2. BackgroundTo begin simply, plants equal <strong>life</strong>. They arethe primary producers that sustain all other<strong>life</strong> <strong>for</strong>ms. They regulate air and waterquality, shape ecosystems and control theclimate. They provide food, medicine,clothes, shelter and the raw materials fromwhich innumerable other products aremade. These benefits are widelyrecognised but poorly understood. Thusplants are both a vital part of the world’sbiological diversity and an essentialeconomic resource <strong>for</strong> human existence.Yet plant extinctions are occurring at a rateunmatched in geological history, leavingecosystems incomplete and impoverished.Current extinction rates are at least 100 to1,000 times higher than naturalbackground rates, with a quarter of theworld’s coniferous trees known to be injeopardy (IUCN, 2006) and as many as15,000 medicinal plants under threat(IUCN/SSC MPSG, 2007). Over 50% ofcycads, used medicinally and the oldestseed plants on earth, are threatened withextinction. This makes them one of themost threatened groups of speciescurrently on the IUCN Red List ofThreatened Species. Whilst the extinctionof a species is the ultimate loss, theprocess of extinction itself has seriousconsequences <strong>for</strong> local ecosystems.Plant to plant interactions effect bothresource availability and habitat structure,and play an important role in mediating theresponses of natural systems (Brooker,2006). Thus the loss of any one speciesweakens an ecosystem’s ability to adapt ina rapidly changing world.“Exploitation pressures have increasedwith growing human population.Although sustainable exploitation ofmany species is theoreticallyachievable, many factors conspire tomake it hard to achieve in practice,and overexploitation remains a seriousthreat to many species andpopulations. Among the mostcommonly exploited species or groupsof species are plants and animalsharvested <strong>for</strong> the medicinal trade”(Millennium Ecosystem Assessment, 2005).Destructive harvesting practices coupledwith the degradation of <strong>for</strong>ests,agricultural expansion, grazing pressureand urbanisation all threaten the survivalof medicinal plants. In short, we areasking more and more from naturalecosystems even as we reduce theircapacity to meet our needs (Kazoora,2002).Ginkgo biloba, a ‘living fossil’ with a longhistory of use in China <strong>for</strong> improving thememory.As we lose species, we lose vitalcomponents necessary to our ownsurvival. Humans, with all their culturaldiversity, are an integral part ofecosystems; ultimately one is entirelydependent on the other. Whilst we driveecosystem change both directly andindirectly, changes in ecosystems causechanges in human well-being also.Adverse impacts on ecosystems haveadverse impacts on cultures andcommunities, often affecting the world’spoorest people with disproportionateseverity. The ecosystem approach toconservation, which puts people at thecentre of ecosystem management, isstrikingly relevant to medicinal plants.Surely, we should save the plants thatsave us?<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 5


3. Medicinal plants <strong>for</strong> healingMedicinal plants have been used bymankind <strong>for</strong> millennia; their use is as oldas humanity itself. The range of speciesused and their scope <strong>for</strong> healing is vast.Cures as yet undiscovered may exist inplants as yet undescribed. Currently, it isestimated that the number of higher plantspecies used worldwide <strong>for</strong> medicinalpurposes is more than 50,000(Schippmann et al., 2002). This equates toapproximately 20% of the world’s vascularflora and constitutes the biggest spectrumof biodiversity used by people <strong>for</strong> aspecific purpose (Hamilton et al., 2006).Traditional medicine“Traditional medicine is the sum totalof the knowledge, skills and practicesbased on the theories, beliefs andexperiences indigenous to differentcultures, whether explicable or not, usedin the maintenance of health as well asin the prevention, diagnosis,improvement or treatment of physicaland mental illness”(World Health Organisation (WHO), 2003).In 1960, at the cave site of Shanidarin what is now north-eastern Iraq,the skeleton of an adult male wasdiscovered, lying on his left side ina partial foetal position. He’d beenburied some 60,000 years ago.Routine soil samples were gathered<strong>for</strong> pollen analysis in an attempt toreconstruct the site’s palaeoclimateand vegetational history. In some ofthe samples concentrated clumps ofpollen were found suggesting thatentire flowering plants had beenburied close to the man. Though thesource of the pollen is hotly debated,a study of the particular flower typessuggested that the flowers may havebeen specifically chosen <strong>for</strong> theirmedicinal properties. Yarrow (Achilleaspp.), St. Barnaby’s thistle (Centaureaspp.), groundsel (Senecio spp.) androse mallow (Hibiscus spp.) amongstothers were represented in the pollensamples, all of which have longknowncurative powers as stimulants,astringents and anti-inflammatories.• In China, Traditional Chinese Medicine(TCM) is largely plant-based (80%) andTCM preparations account <strong>for</strong> 30-50%of total medicinal consumption, risingto 90% in rural areas (WHO, 2003).• In India, Ayurvedic medicine, a systemmore than 5,000 years old, is based onsome 2,000 plant species (Zedan,2002).• In Sub-Saharan Africa, the ratio oftraditional healers to the populationis approximately 1:500, while medicaldoctors have a 1:40,000 ratio to therest of the population (Richter, 2004).In fact, of the total pharmaceutical drugsupply available worldwide, only 15%is consumed in developing countries(Lydecker et al., 1992), supporting the


much-quoted WHO’s estimate that 80%of people worldwide rely on traditionalmedicine <strong>for</strong> their primary healthcare.The majority of these people are indeveloping countries, where rapidpopulation growth is expected to increasepressures on medicinal plant resources.The greater part of traditional therapyinvolves the use of plants. With little orno access to modern pharmaceuticalsand a strong cultural preference <strong>for</strong>traditional medicine, medicinal plants arethere<strong>for</strong>e fundamental to the well-being ofbillions of people.Demand <strong>for</strong> traditional remedies is alsoincreasing in so-called developedcountries, alongside growingenvironmental awareness and a desire<strong>for</strong> natural healing through naturalproducts.‘Modern’ medicineOf course, allopathic or ‘modern’medicine also owes a great deal tomedicinal plants. Catharanthus roseus<strong>for</strong> example, treats leukaemia andHodgkin’s disease. Morphine andcodeine are produced from cultivatedopium poppy, Papaver somniferum.Aspirin was originally found in willow bark(Salix spp.). Quinine from the cinchonatree has been the primary treatment <strong>for</strong>malaria <strong>for</strong> centuries. Digitalin medicines,Digitalis spp.extracted from the leaves of the commonfoxglove (Digitalis spp.), are widely used<strong>for</strong> a variety of heart conditions. Topicalsteroids <strong>for</strong> eczema are produced fromthe yam (Dioscorea spp.) or from sisal(Agave spp.) and the alkaloidGalantamine, sourced from the bulbs ofsnowdrops (Galanthus spp.) is used totreat Alzheimer’s disease, slowing downthe progression of dementia.In many cases modern chemistry cannotoffer viable alternatives to activebotanical compounds. The compoundpaclitaxel (found in Taxus spp. and sourceof the anti-cancer drug, taxol) wasdescribed as the kind of molecule that nochemist would ever sit down and think ofmaking;“If contemporary chemistry is nowallowing us to merely copy suchmolecules, one can imagine the nearimpossibility of designing from scratch amolecule with a comparable combinationof <strong>for</strong>m and biological function”(Capson, 2004).Predictions that advances in chemicalsciences and synthetic materialdevelopment would lessen the need <strong>for</strong>natural materials have proved to bewrong, and modern medicine dependson the continuing availability ofbiological materials as anincomparable source of moleculardiversity.Taxus spp.In fact, as many as 50% of prescriptiondrugs are based on a molecule thatoccurs naturally in a plant, with some25% of prescription drugs derived directlyfrom flowering plants or modelled on plantmolecules (Foster and Johnson, 2006).<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 7


4. Medicinal plants <strong>for</strong> livelihoodsMedicinal plants are clearly an importantglobal resource in terms of healthcare butthey are also an important economicresource, traded extensively on scalesranging from the local to the international.Internationally, the trade in medicinalplants is estimated to be worth $60 billionper year (World Bank, 2004) increasing ata rate of 7% a year (Koul and Wahab,2004).Very little of the raw material to supplythis demand is from cultivated sources.Of the 3000 or so species known to be ininternational trade (Schippmann et al,2006) there are approximately 900 <strong>for</strong>which commercial cultivation is underwayor in development (Mulliken and Inskipp,2006). Putting it another way, about 70-80% of the medicinal plants being tradedin the world’s most important rangecountries <strong>for</strong> medicinal plants originatefrom wild-collection (WWF/TRAFFICGermany, 2002). Many of these speciesare widespread and abundant but <strong>for</strong>naturally rare and heavily exploitedspecies wild collection can be a majorthreat with local extinction the outcome.It is the collection <strong>for</strong> commercial traderather than home-use that isoverwhelmingly the problem (Hamilton,2003).Though notoriously poorlydocumented, and though ourunderstanding of the biology, ecologyand status in the wild of mostmedicinal plants is very fragmented,this level of wild harvest is said to becurrently unsustainable.We know this because herb-gatherers arehaving to go farther and farther afield toharvest the plant they want; they’reexperiencing a drop in harvest levels.Some species just aren’t there anymore.Un<strong>for</strong>tunately, the motivation of shorttermprofit increase neglects allconsiderations of sustainability, butconservation intervention can occur atseveral points along the supply chain.The consequences of unsustainableharvest are far-reaching, and not simplyconfined to a loss of healthcare orbiodiversity. Many of the world’s poorestpeople rely on the collecting and sellingof wild medicinal plants <strong>for</strong> incomegeneration. Though prices paid togatherers tend to be very low medicinalplant collection provides a significantincome <strong>for</strong> the often marginal, rural poor(World Bank, 2004).Gentiana luteaGentiana lutea (Yellowgentian) is found in themountains of central andsouthern Europe. Gentianroot (which can be asthick as a person’s arm)has a long history of useas an herbal bitter in thetreatment of digestivedisorders. An Egyptianpapyrus from 1200 B.C.mentions gentian as aningredient in medicines(Foster and Johnson,2006).The root contains one ofthe bitterest substancesknown to science (thebitter taste can still be detected atdilutions of herb to water 1:20,000) andit stimulates the taste buds and brainreflexes to promote the secretion of salivaand gastric juices. As such it has beenused as an appetite stimulant in thetreatment of anorexia (Foster, 2006).It is said to be especially useful in statesof exhaustion from chronic disease andin cases of debility or weakness of thedigestive system; strengthening the humansystem by stimulating the liver, gall bladderand digestive system (<strong>Plants</strong> <strong>for</strong> a Future,2004).Most imports of G.lutea originate fromwild harvest and occasionally fromcultivation in south east Europe(WWF/TRAFFIC Germany, 2002).The species is endangered or criticallyendangered over most of its range; it isincluded in the Red Data Books ofBulgaria, Albania and Transcarpathia;wild harvest is banned in Montenegro;the species is protected by law inSerbia and the Ukraine and it isconsidered threatened in Turkey.Gentiana lutea is recorded in cultivationin 48 botanic gardens (PlantSearchdatabase). The gathering ofpropagation data from these gardensand the exchange of this in<strong>for</strong>mationwill help to ensure the ex situconservation of this species and willsupport restoration and reintroductionef<strong>for</strong>ts. BGCI aims to facilitate thiswork though its medicinal plantsprogramme.8<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens


• About 20,000 tons of medicinal andaromatic plants worth US$18-20 millionare traded every year in Nepal alone,and about 90% are harvested inuncontrolled fashion by landless,resource-poor mountain farmers <strong>for</strong>whom the harvest and trade inmedicinal plants constitutes their only<strong>for</strong>m of cash income. The situation issimilar in Bangladesh, Bhutan, India,and other countries of South Asia(MAPPA, 2007).• In Namibia, there are an estimated5,000 to 10,000 Devil’s Claw(Harpagophytum spp.) harvesters,50 to 100 middlemen and 17 Namibianexporters. The retail value in 2001 wassome US$40 million, though Namibiacaptures at most 5% of the retail valueof the trade (Cole and Stewart, 2006).• Ethnoveterinary medicine is used bylivestock raisers throughout the worldto keep their animals healthy andproductive, since modern treatmentsmay be expensive and inaccessible inremote areas (Mathias, 2001).Rows of ginseng and mushroom elixirs <strong>for</strong> sale in Seoul, Korea.Aconitum spp.Aconitum heterophyllum (Patris) isendemic to the alpine and sub-alpinezones of the north-west Himalayas.It grows only in localised restrictedecological niches and is said to neitherinvade new areas nor survive at loweraltitudes (Beigh et al, 2005).The species has;1 name in Arabic, 5 in Hindi, 2 inKannada, 1 in Malayalam, 2 in Marathi,3 in Persian, 70 in Sanskrit, 83 in Tamil,3 in Telugu, 5 in Tibetan and 4 in Urdu(FRLHT, no date).The dried root is commonly used totreat gastric disorders and high fevers,as a substitute <strong>for</strong> quinine and to treattoothache and scorpion or snake bites.It is a high value species; gatherers canexpect to receive around Rs 1500/kg(approximately US$37) (Uniyal et al,2006). Traditionally, it was harvestedevery two to three years. It is nowharvested every year and subject to alengthened harvesting season, placingthe species under heavy pressure(Singh, 2006). The species shows poorseed germination and low seed survivalthere<strong>for</strong>e regeneration is low undernatural conditions. This characteristic,combined with non-judiciousexploitation, over-grazing and habitatdestruction mean that the species isnow hard to find and criticallyendangered.Aconitum heterophyllum is recorded incultivation in only 4 botanic gardens(PlantSearch database). BGCI willthere<strong>for</strong>e support the ex situconservation of this species by alertinggardens to the conservation needs ofthe species, gathering species-specificdata and facilitating knowledge sharebetween gardens.The world’s greatest concentration ofmedicinal plant wealth is found in tropicaldeveloping countries that are beset byacute poverty. In these regions, the lossof biodiversity and land degradation isaccelerating as poverty is increasing.The loss of livelihood is a very real concerngiven that approximately 1 billion people, afifth of the world’s population, live on lessthan US$1 a day (World Bank, 2007).A common definition is that a livelihood isthe financial means whereby one lives; <strong>for</strong>example, collecting wild medicinal plants<strong>for</strong> sale. However, this does notnecessarily mean that the plantscollected are sufficient to satisfy anindividual’s needs or to lift them out ofpoverty. Such a livelihood cannotthere<strong>for</strong>e be sustainable. A sustainablelivelihood is one that can cope with andrecover from stresses and shocks whilstmaintaining or enhancing its capabilities<strong>for</strong> the future and not undermining thenatural resource base (Kazoora, 2002).Sustainable use meets the needs of thepresent without compromising the abilityof future generations to meet their ownneeds (Brundtland, 1987).<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 9


5. Approaches to medicinal plantconservationMedicinal plant conservation is challenging,since the taxa occur in a wide range ofhabitats and geographic regions. Theirconservation threats and ultimate use arediverse and users are not only local ruralcommunities but also far away urbancitizens. However, it is widely agreed thatthe conservation of medicinal plants (andbiodiversity in general) can be achievedthrough an integrated approach balancingin situ and ex situ conservation strategies.Medicinal plant conservation mustthere<strong>for</strong>e operate within several spheres;drawing together disparate groups andmutually acknowledging differentstakeholder interests in order to succeed.The policy contextA policy trend positively linkingbiodiversity conservation with humandevelopment is gaining momentum andpeople’s access rights to naturalresources necessary <strong>for</strong> their survivalhave improved with policy provisions.• The Convention on BiologicalDiversity (CBD) was ratified in 1992 atthe Rio Earth Summit. The 190 Partieshave agreed to commit to protectbiodiversity, develop sustainably andengage in the equitable sharing ofbenefits from the use of geneticresources.The conservation of biodiversity isacknowledged as the cornerstone ofsustainable development. For morein<strong>for</strong>mation on the CBD go towww.cbd.int.• The World Trade Organisation’s (WTO)agreement on Trade-Related Aspectsof Intellectual Property Rights(TRIPS), 1994, sets out how to dealwith the commercial use of traditionalknowledge and genetic material bythose other than the communities orcountries where these originate,especially when these are the subjectof patent applications. Morein<strong>for</strong>mation on the WTO and TRIPSAgreement is available at www.wto.org.The Chiang Mai Declaration of 1988 led to the publication of the first Guidelineson the Conservation of Medicinal <strong>Plants</strong> (currently being updated), recognisingthe “urgent need <strong>for</strong> international co-operation and co-ordination to establishprogrammes <strong>for</strong> the conservation of medicinal plants to ensure that adequatequantities are available <strong>for</strong> future generations” (WHO, 1993).The guidelines detailed the expertsmost needed <strong>for</strong> a programme ofconservation and sustainable utilisationof medicinal plants, though terms mayhave changed in the almost 20 yearssince, the roles remain just as current.Agronomists:Conservation campaigners:Ecologists:Ethnobotanists:Health policy-makers:Horticulturists:Legal experts:Park managers:Park planners:Pharmacologists:Plant breeders:Plant genetic resourcespecialists:Plant pathologists:Religious leaders:Resource economists:Seed biologists:Taxonomists:Traditional health practitioners:To improve techniques <strong>for</strong> cultivating medicinal plantsTo persuade the public of the need to conserve medicinal plantsTo understand the ecosystems in which medicinal plants growTo identify the use of plants as medicines in traditional societiesTo include conservation and utilisation of medicinal plants in their policy and planningTo cultivate medicinal plantsTo develop effective legal mechanisms that ensure that collection of medicinal plants is atlevels that are sustainableTo conserve medicinal plants within their parks and reservesTo ensure the park and reserve system contains the maximum diversity of medicinal plantsTo study the application of medicinal plantsTo breed improved strains of medicinal plants <strong>for</strong> cultivationTo assess the genetic variation in medicinal plants andmaintain seed banks of medicinal plantsTo protect the cultivated medicinal plants from pests and diseases without using dangerouschemicalsTo promote a respect <strong>for</strong> natureTo evaluate the patterns of use and the economic values of medicinal plantsTo understand the germination and storage requirements of the seed of different medicinal plantsTo identify the medicinal plants accuratelyTo provide in<strong>for</strong>mation on the uses and availability of medicinal plants10<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens


Access and benefit sharing (ABS)One of the three fundamental objectivesof the CBD is to promote the fair andequitable sharing of the benefits arisingout of the utilisation of genetic resources.One way of doing this is by confirmingthe sovereign rights of the State over itsbiological resources. The bioprospectingof plants <strong>for</strong> potential new drugs raisesissues about the protection of traditionalknowledge and the mechanisms toensure that indigenous peoples benefitfrom uses of their resources.• The UNCTAD BioTrade Initiative(launched in 1996) promotes thesustainable use of goods and servicesderived from biodiversity, in support ofthe objectives of the CBD(www.biotrade.org/).• The eight Millennium DevelopmentGoals (MDGs) were agreed by worldleaders in 2000, providing an agenda<strong>for</strong> reducing poverty and improvinglives through environmentalsustainability by the target date of2015. Any measures which enable thesustainable use of natural resources toimprove livelihoods will contribute tothe MDGs. The MDGs can be viewedat www.un.org/millenniumgoals/.• The Millennium EcosystemAssessment (MEA) assessed theconsequences of ecosystem change onhuman well-being, gathering data from2001 to 2005 and providing a scientificappraisal of the condition and trends inthe world’s ecosystems and theservices they provide, as well as thescientific basis <strong>for</strong> action to conserveand use them sustainably(www.millenniumassessment.org).• The Doha Declaration of 2001 aimedto ensure that the TRIPS agreementand the CBD support each other;“allowing <strong>for</strong> the optimal use of theworld’s resources in accordance withthe objective of sustainabledevelopment, seeking both to protectand preserve the environment and toenhance the means <strong>for</strong> doing so in amanner consistent with their respectiveneeds and concerns at different levelsof economic development”.• In 2002 the CBD adopted the GlobalStrategy <strong>for</strong> Plant Conservation(GSPC), which specifies 16 outcomeorientatedtargets <strong>for</strong> delivery by 2010.See Annex 3 and www.plants2010.org.• The 2002 World Summit onSustainable Development aimed topromote a global commitment tosustainable development, improving thelives of the world’s poorest people aswell as reversing the continueddegradation of the global environment.For the latest developments seehttp://www.un.org/esa/sustdev/index.html.• The WHO launched their TraditionalMedicine Strategy in 2002, discussingthe role of traditional medicine in healthcare systems. View at http://www.who.int/medicines/publications/traditionalpolicy/en/.• In 2004, the Addis Ababa Principlesand Guidelines to the CBD detailed 14interdependent practical principles andoperational guidelines that govern theuses of components of biodiversity toensure the sustainability of such use.These can be viewed on the CBDwebsite, as be<strong>for</strong>e.• Also in 2004, a new paragraph wasadded to the Convention onInternational Trade in EndangeredSpecies of Wild Fauna and Flora(CITES) Resolution Conf.8.3 statingthat the Conference of the Partiesrecognizes that implementation ofCITES listing decisions should take intoaccount potential impacts on thelivelihoods of the poor. Seewww.cites.org <strong>for</strong> further in<strong>for</strong>mation.Homalanthus nutans• Homalanthus nutans (the mamala tree)is native to the rain<strong>for</strong>ests of the SouthPacific island of Samoa. It hastraditionally been used to treat anumber of conditions; from back painto hepatitis, diarrhoea and yellow fever.Researchers at the University ofCali<strong>for</strong>nia, Berkeley, in the US identifieda promising AIDS drug (Prostratin) inthe bark of the tree. Samoa there<strong>for</strong>edeclared sovereign rights over thespecies, including the actual genesequences, and signed an ABSagreement with the University in 2004(picture above). The agreement givesSamoa and the University equal sharesto any commercial proceeds resultingfrom the genes. Samoa’s 50% sharewill be allocated to the government, tovillages and to the families of traditionalhealers. Another facet of theagreement is a requirement that anysubsequent commercialised drug mustbe supplied to developing countriesfree, at cost or at very nominal profit.<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 11


• In October 1991, the Costa RicanAsociacion Instituton Nacional deBiodiversidad (INBio), a private, nonprofit,scientific organization andMerck, a U.S. multi-nationalpharmaceutical corporation, signed atwo year agreement. In the agreement,INBio would supply Merck withsamples among the plants, insects andmicroorganisms collected from CostaRica’s protected <strong>for</strong>ests. Merck thenwould have the right to use thesesamples to create new pharmaceuticalproducts. Merck paid one milliondollars to INBio <strong>for</strong> the right to analyzean agreed-upon number of indigenousplant and animal samples. Merck (it isbelieved) will pay INBio between one tothree percent royalties <strong>for</strong> any productdeveloped through the agreement.Ten percent of the initial one milliondollars and fifty percent of any royaltywill be invested in biodiversityconservation through Costa Rica’sMinistry of Natural Resources. (Tradeand Environment Database, no date).Clearly such agreements are beneficial inmany ways to countries rich in biodiversitybut without the capacity to develop theseresources. However, there are concernsthat such legislative measures may restrictaccess to plant resources <strong>for</strong> noncommercialuse such as research,conservation, education and display.Considering the key role that botanicgardens play in educating the publicabout medicinal plant use, access tomedicinal plants <strong>for</strong> education and displaypurposes as well as <strong>for</strong> conservation andresearch activities, is important. Botanicgardens have in recent years beenworking to develop harmonisedapproaches to implementing the ABSprovisions of the CBD. Two voluntaryapproaches have been developed,the Principles on Access to GeneticResources and Benefit-Sharing (thePrinciples) and the International PlantExchange Network (IPEN).• The Principles provide a framework tohelp guide gardens when developingtheir own individual policies.• IPEN establishes a system of facilitatedexchange <strong>for</strong> a network of gardens thathave signed up to a Common Code ofConduct. The IPEN system only coversnon-commercial use of livingcollections.Non-monetary benefits resulting fromplant exchange can include knowledgetransfer, technical support, staff exchangeand capacity building to strengthenconservation work in the country of originof the plant material.Further in<strong>for</strong>mation can be found atwww.bgci.org/abs.Cultivation versus wild harvestCultivation has long been suggested as apossible mitigation to the unsustainablewild harvest of medicinal plants,simultaneously taking the pressure offwild stock whilst boosting commerce.Along an agronomic model, modernmethods of plant breeding, propagationand post-harvest processing techniquesPanax quinquefoliusPanax quinquefolius (Americanginseng) has been heavily traded inNorth America <strong>for</strong> over a century;“We were down in the Tennesseemountains when there came slowlydown the mountain trail a dilapidatedspecimen of humanity, slouch hat,bare foot, coat hung on one shoulder,and a sack, of unknown origin, in hishands. He saw us, heard us as wegreeted – but without turning the headslunk on like some phantom creatureinto the <strong>for</strong>est labyrinth. ‘Humph’,said the guide. ‘You might a’ known.You can’t expect nothin’ of a ginsengdigger.’”(Koch, 1910).It is highly prized as a universal remedy ineast Asia, where more than 95% ofharvested roots end up. Traded ginsengtypes include wild, wild-stimulated,cultivated woods-grown and cultivatedfields-grown. Field-grown ginseng rootsreach a size in three years that can only beattained by 15-30 years of growth undernatural <strong>for</strong>est conditions, and are very palein colour compared to wild-grown roots.Wild ginseng root has the greatestperceived medicinal value of all theginseng types and this is reflected inprice – from as much as US$1300/kg <strong>for</strong>wild roots to as low as US$44/kg <strong>for</strong>field-cultivated roots (Pierce, 2002).Though there is a move towards gradingthe roots according to the quantity ofactive chemical content, buyers primarilygrade roots according to physicalcharacteristics; size (the bigger thebetter), shape (the more ‘man-shaped’and thicker the better), age (the olderthe better) and colour (the darker thebetter) (Sinclair, 2005).Illegal wild harvest is known to occur;10,515 illegally harvested roots wereseized between 1991 and 1999 in theGreat Smokey Mountain National Parkalone (Pierce, 2002). Conservationef<strong>for</strong>ts have there<strong>for</strong>e includedemploying marker technology to enabledistinction between cultivated and wildroot, as well as research into the activecompound content. P .quinquefolius iswidely cultivated commercially, andrecorded in eight botanic gardencollections (PlantSearch database).12<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens


Harvesting Prunus africana.allow medicinal plant products to beengineered to a consistent and highstandard, infinitely more appropriate <strong>for</strong>standardised pharmaceutical use.The cultivation, management andenrichment planting of high value plantsis there<strong>for</strong>e an important strategy to meetconsumer demands and reduce theimpacts of markets on biodiversity.However, cultivation often requires majorinputs <strong>for</strong> a far-off return in a fluctuatingmarket characterised by ‘fads’. Thoughseveral medicinal plants are cultivated ona large scale (Arnica montana, Hamamelisvirginiana, Panax quinquefolius andCatharanthus roseus to name a few) it isnot economically feasible to commerciallycultivate all of the medicinal plants thatare threatened in the wild. (It should benoted that, despite cultivation, several ofthese species were also considered aspriorities <strong>for</strong> further conservation attentionin the wild, see Annex 5). There is littleincentive to bring into cultivation speciesthat are required in relatively smallvolumes, are slow growing, are believedto be more potent in their wild <strong>for</strong>m or donot command sufficiently high prices.Moreover, there are social, economic andecological benefits to wild harvest. Asmentioned, since wild collection is mostlycarried out in low-wage countries and bylow-income, underprivileged groups it’s achance <strong>for</strong> the poorest of people to get atleast some income, despite having no land.Wild harvest also gives an economic valueto ecosystems and habitats and thusprovides an incentive <strong>for</strong> the protection ofsomething much larger than just themedicinal plant. Though theconsequences of collecting activity are stillvery little understood, the involvement oflocal people in sustainable managementpractices increases both their desire andability to protect wild populations fromover-exploitation. Of course, theassumption here is that stocks aresufficient, demand will remain constantand the structures and dynamics withinlocal communities will remain stable.Rauvolfia serpentinaRauvolfia serpentina (Indiansnakeroot, Sarpaghanda) is member ofthe dogbane family, found in India,Pakistan and south east Asia.“The primary folk use <strong>for</strong> the extractwas as a means of attaining states ofintrospection and meditation, andIndian holy men, including MahatmaGhandi, were habitual users of thedrug”(Mann, 1992).But the plant is also an importanthealer, used <strong>for</strong> stomach disorders,snakebite and epilepsy. R. serpentinais also the source of the alkaloidresperine, which revolutionized thetreatment of hypertension in the 1950sand is still commonly prescribed today.Chemically similar to serotonin,resperine was also used to treat severemental illnesses due to its powerfulsedative properties.Once found in most of tropical India,by 1998 it was confined to a range ofless that 5,000km 2 ; with an area of wildpopulation occupancy said to be lessthan 500km 2 (Mamgain et al. 1998).Export was banned by the IndianMinistry of Commerce in 1994, and inNepal in 2001 (Aryal, no date) andtrade is now less than it was in pastIt should be noted that both large-scalecultivation and unsustainable wild harvestlead to genetic erosion. When cultivated,artificial changes (to intensify theconcentration of certain compounds)often occur very quickly, unlike in nature.In the short term the desired results areachieved but, in terms of geneticdiversity, there may be long term negativeconsequences. It is a diverse gene poolthat contributes to the ability of speciesor populations to maintain resistance todiseases and to adapt to a changingclimate. Environmental conditions atevery level are constantly changing, andonly diversity can ensure that someindividuals will be able to adapt to thesechanges.CITES and medicinal plantsThe Convention on International Trade inEndangered Species of Wild Fauna andFlora (CITES) provides varying degrees ofprotection to more than 33,000 plantspecies. Of these, about 240 aredecades (CITES, 2005).However the rapiddecline and isolatednature of snakerootpopulations means thatwild genetic stock isseverely depleted.On a small scale India has successfullycultivated snakeroot <strong>for</strong> many decades,<strong>for</strong> example in hospital gardens, andcontinues to invest in this area. It isnot clear how successful this has beenhowever, given that the speciesrequires at least two years be<strong>for</strong>ebearing marketable product. Furtherexperiments have shown that netreturns are higher when Rauvolfia isinter-cropped than when grown alone,in this way yielding a year roundharvest and down-playing the slowearly growth of the species(Maheshwari, 1985).Rauvolfia serpentina is recorded incultivation in 22 botanic gardens(PlantSearch database). However, littleis known about the genetic diversity ofsuch cultivated stock and accessionsin genebanks. A genetic study of theplants in botanic garden collections willbe encouraged by BGCI with a view todeveloping a strategy <strong>for</strong> therestoration of wild populations.medicinal (Schippmann, 2001) eventhough only approximately 30 have beenlisted specifically because of concernover their trade as medicine. Theintention of CITES is to promote asustainable trade in listed species.<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 13


Hoodia spp.Hoodia spp. are slowgrowing,perennial,spiny succulent plants.They occur in a widerange of arid habitatsin southern Africa,typically on arid gravelplains. Detailedin<strong>for</strong>mation on thedistribution andpopulation status ofindividual taxa islimited but ten of the16 taxa assessedhave been classified as threatenedaccording to IUCN Red List categories,with four taxa classified as Vulnerablein 2002.Traditionally used by the San bushmenof South Africa, strong, globalcommercial interest in the genus hasresulted from the isolation andpatenting of an active ingredient (P57)which acts as an appetite suppressantand is claimed to help weight loss;“Amazing, most effective safe weightloss with no side effects advancedappetite suppressant available!”“HoodiThin - Feel full faster andstay full longer!” “Hoodia diet pillsare guaranteed to work <strong>for</strong> you or itcosts absolutely nothing!”The active ingredient has been isolatedfrom H. gordonii which only occurs inNamibia and South Africa. This speciesis considered to be abundant andwidespread. However, some of theother taxa in the genus exist infragmented populations (some with asfew as 250 individuals) and cannoteasily be distinguished from H. gordonii.These species are there<strong>for</strong>e under threatfrom over-collection <strong>for</strong> trade. AllHoodia species were listed on CITESAppendix II in 2005, but illegal trade isknown to occur.SpeciesNo. of botanicgarden collectionsHoodia bainii 2Hoodia barklyii 2Hoodia currori 1Hoodia dregei 5Hoodia gibbosa 1Hoodia gordonii 10Hoodia juttae 3Hoodia langii 1Hoodia macrantha 7Hoodia parviflora 1Hoodia pilfera 4Hoodia pillansii 1Hoodia ruschii 3There is significant commercial attentionon this genera, given the lucrative natureof its promise. The species should onlybe grown or collected with a permit andplantations have been in development<strong>for</strong> several years. Demand however,remains a threat to certain populations.As a suggested species <strong>for</strong> priorityconservation action, Hoodia will beincluded in BGCI’s wider medicinal plantconservation programme.CITES regulates international tradebetween signatory countries. It is notapplicable to domestic or non-signatorytraffic. Monitoring of the trade under theterms and conditions of the Convention iscomplex and only partially successful.It is thought that a huge amount of tradein medicinal plants goes unrecorded andunregulated, <strong>for</strong> example that withinChina or between Nepal and India.Even trade movements covered by CITESare poorly understood, hampered byidentification problems, under-resourceden<strong>for</strong>cement and inconsistent nationalinterpretations of the international statute.Most medicinal plant species are nottraded under their scientific name, andcome in a variety of parts and derivatives.Aquilaria malaccensis, <strong>for</strong> example, has atleast 50 trade names (Lange andSchippmann, 1999); an import ofwoodchips can be listed as ‘bark’ withno species name.“It is indisputable that monitoring thetrade in wild collected plants is onlyuseful if carried out at species level andthat without such, analysis of the tradeand its impact on populations cannot becarried out effectively”(Schippman, 1994).However, CITES is an importantmechanism <strong>for</strong> trade regulation and tohighlight critical issues. Botanic gardenscan be involved in the success of CITESin a number of ways.For more in<strong>for</strong>mation on CITES andbotanic gardens go to www.bgci.org/citesor see A CITES manual <strong>for</strong> botanicgardens (Oldfield and McGough, 2007).The IUCN Red List of ThreatenedSpeciesIt is essentially a framework <strong>for</strong>classifying species according to theirextinction risk. So far, almost 40,000species have been assessed, of whichsome 12,000 are plants. It is difficult tospecify what proportion of threatenedmedicinal plant species have beenevaluated using the IUCN Red Listcategories and criteria but it is generallyrecognised to be a low proportion.For more in<strong>for</strong>mation on the IUCN SSCand the IUCN SSC Medicinal <strong>Plants</strong>Specialist Group (MPSG) go towww.iucn.org/themes/ssc/ andwww.iucn.org/themes/ssc/sgs/mpsg/.Seized cycads, said to have variousmedicinal qualities and one of the mostendangered living things on the planet.Policy frameworks and legislation arein<strong>for</strong>med by essential data such as theendangerment assessments made by theSpecies Survival Commission (SSC) ofthe IUCN, which produces a Red List ofThreatened Species. Using a network ofthousands of scientists the Red Listprovides taxonomic, conservation statusand distribution in<strong>for</strong>mation on globallyevaluated species according to specificcategories and criteria (Annex 6).14<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens


6. Medicinal plants and botanic gardensSome 5,000 years ago, a botanicgarden said to have astounded theSpanish conquistadores existed in thecity of Texcoco, the second mostimportant city in the once majesticAztec empire. Approximately 370species of plants still grow there in aconfined geographical area, thoughthe city and the civilisation have longsince disappeared. Researchconducted at the sight has resulted inthe identification of all the plants thatwould have been cultivated in thegarden, all of which have eithermedicinal properties or othereconomic uses (Montúfar, 2007).The Botanical Garden of Padua,founded in 1545 and one of the oldestbotanic gardens in the world, wascreated by the Vatican Republicpurposely <strong>for</strong> the cultivation ofmedicinal herbs. The institutionenabled students to use the garden tolearn how to distinguish between anduse medicinal plants, improving bothlocal healthcare and scientificunderstanding. Similarly, the ChelseaPhysic Garden was founded inEngland in 1673 by the WorshipfulSociety of Apothecaries to trainapprentices to identify plants and tohelp in the cultivation of exotic plants<strong>for</strong> medicine. These gardens thus meta research, economic and health goal.These days, there are over 2,500 botanicgardens in 150 countries around theworld, holding over six million accessionsof living plants representing around80,000 species. They are there<strong>for</strong>e majorrepositories of species diversity andcollectively represent many, many yearsof learning.As institutions, their work remit occupiesseveral spheres; from scientific researchto education to in<strong>for</strong>ming legislation torunning community-based projects – andit’s a remit that’s widening in both scopeand importance alongside globalpopulation increase, rapid urbanisationand relentless pressure on our collectivewild resources. Increasingly, botanicgardens are more than just ‘prettyplaces’.Whilst conservation has not been atraditional garden activity, it is becomingmore so, as demonstrated by theInternational Agenda <strong>for</strong> Botanic Gardensin Conservation (Wyse Jackson andSutherland, 2000) launched in 2000 toprovide a common global framework <strong>for</strong>garden policies and signed by 432botanic gardens so far, as well as theinvolvement of botanic gardens in thedevelopment of the GSPC.Botanic gardens have a long-standingconnection to medicinal plants inparticular, since the sole purpose of allearly botanic gardens was to grow andstudy medicinal plants. They areinherently well-placed to respond to thevery specific local conservation needs ofmedicinal plants and the people who relyon them <strong>for</strong> health and livelihood in aparticular region. Moreover, they areprobably the most important agencies <strong>for</strong>the conservation of native medicinalplants, since plants are not often thepriority of other conservation bodies andgovernment agencies related toagriculture pay little attention to thosespecies of undetermined economic use.Using botanical and cultivationknowledge there are a number of keyways in which botanic gardens cancontribute towards medicinal plantconservation and sustainable use.<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 15


Questionnaire responses illustrated thewide range of areas in which botanicgardens are involved with medicinalplant conservation, the positive effectsof this work and the linkages betweenbotanic gardens and otherconservation agencies.Ex situ conservationEx situ conservation remains the main remitand area of expertise of botanic gardens.It provides an important ‘insurance’ againstthe loss of plant genetic resources, with akey role to play in terms of preservationand species re-introduction programmes,education and research.This role has been defined by theGSPC, specifically Target 8, which calls<strong>for</strong> 60% of threatened plant species inaccessible ex situ collections,preferably in the country of origin, and10% of them included in recovery andrestoration programmes.Living collectionsThe conservation of plant resources canbe achieved through different methodssuch as seed banks, in vitro storagemethods, pollen banks and DNA banksas well as the maintenance of livingcollections. This is particularly importantwith threatened medicinal plants whereprotection in the wild may not be realisticin the short-term, or where ex situ workcannot yet be directly linked to in situ.The resources provided by thesecollections are important <strong>for</strong> in siturecovery programmes.Target 9 of the GSPC calls <strong>for</strong> 70% ofthe genetic diversity of the majorsocio-economically important plantsconserved.Wuhan Botanic Garden, China hasdeveloped a medicinal plant gardenwith over 800 species <strong>for</strong> education,research and preservation (Z. Jiang,pers.comm.).A medicinal plant seed bank andherbarium has been developed atAl-Quds University Botanic Gardenin Palestine, to preserve wild nativemedicinal plants (K. Sawalha,pers.comm.).In China, the Shangri-La AlpineBotanical Garden in Yunnan provinceis designing a Tibetan Medicinal <strong>Plants</strong>Garden, collecting those species mostcommonly used (Liu, pers.comm.).Chicago Botanic Garden maintainsboth an outdoor collection and a seedbank of local medicinal plant species,<strong>for</strong> detailed evaluation of active plantcompounds. The identification ofuseful medicinal compounds shouldnot only promote public health butalso underscore the importance ofprotecting native flora.Jardin Botanico de Bahia Blanca inArgentina maintains a display ofmedicinal plant species used on alocal scale (Villamil, pers.comm.).Plant recordsAn essential, defining feature of a botanicgarden is the maintenance of plantrecords on the living collection. Eachrecord typically records the scientificname of the plant and its origin (whetherof known wild origin or cultivated source).Many botanic gardens hold collections ofmedicinal plants – see <strong>for</strong> example theBGCI Directory of Medicinal PlantCollections in Botanic Gardens (WyseJackson and Dennis, 1998) but the valueof these has never been fully assessed.BGCI maintains the PlantSearch databasewhich records data on plants in botanicgarden collections. As of August 2007 thePlantSearch database held details on over2,540 botanic gardens, 681 of which haveuploaded their species data, totalling505,000 records of approximately 140,000different taxa. The database is available<strong>for</strong> public use, although garden addressesare only accessible after requesting furtherin<strong>for</strong>mation from the garden itself, due tothe valuable nature of some of the plantsheld.As part of the ‘Safety Nets <strong>for</strong> Medicinal<strong>Plants</strong>’ project, BGCI has updatedPlantSearch to include in<strong>for</strong>mation onsome 3,000 medicinal plants species aswell as all plants listed on CITES. We haveobtained over 40 lists of key speciesincluding almost 1,000 species threatenedin the wild due to unsustainableharvesting and habitat destruction (seeAnnex 2). Work is currently underway ona detailed gap analysis of key medicinalplant species in botanic gardencollections and the conservation workbeing done with them, if any.Since botanic gardens hold the largestassemblage of plants outside ofnature, it makes sense to worktowards a global inventory of medicinalplants held in botanic gardens.BGCI is working towards this aim.ResearchBotanic gardens provide a permanentlocation around which an infrastructurecan develop. Around the world, theyhave become centres <strong>for</strong> the researchand study of disciplines as diverse astaxonomy, ecology, agronomy,horticulture, ethnobotany and habitatrestoration, all of which in<strong>for</strong>m medicinalplant conservation.


Xishuangbanna Tropical BotanicGarden in China has begun a researchprogramme into the propagation andre-introduction of local Dendrobiumspecies, used extensively in TCM.This will include field work to assessthe status of populations in the wildand research into cultivation techniques(Y.Shouhua, pers.comm.).Leiden Botanic Garden in theNetherlands has begun researchingways of distinguishing between legallyproduced and illegally wild harvestedagarwood (Aquilaria and Gyrinops spp.)using DNA markers in plantation crops(van Uffelen, pers.comm.). Thisresearch work aims to assist the controlof illegal wild harvest and trade inthreatened medicinal plants.In 2006, the Pfizer Plant Laboratorywas opened in New York BotanicGarden, systematically screening plantsin the search <strong>for</strong> active medicinalcompounds, and studying the efficacyof these compounds. This is not assimple as it sounds. Normally, allmedicinal plants have one or twoprimary compounds and a number ofsecondary compounds. The efficacy ofthe plants in medicinal use depends onthe interaction of all roughage,secondary and mucous compoundswith the primary active compounds.If primary compounds are isolated, theymay have completely different effectsthan in combination with the cocktail ofsecondary compounds of the respectiveplant (WWF/TRAFFIC Germany, 2002).Efficacy also depends, to a certainextent, on abiotic factors of theenvironments and on collectionmethods. It differs from location tolocation (soil quality, mineral content,moisture content, temperature, intensityof light) and depends on the weatherconditions at the time of collection.The Jodrell Laboratory at RBG, Kew in theUK is dedicated to ethnobotany and runsnumerous research projects into thechemistry, bioactivity and taxonomy ofmedicinal plants (Olwen, pers.comm.).This scientific research can be used toin<strong>for</strong>m legislation and policy development.Turpan Desert Botanic Garden hasconstructed an Ethnic Medicinal PlantGarden, researching the use of medicinalherbs used by the Uygur people ofXinjiang (Tan, pers.comm.).At Reading University in the UK theFaculty of Pharmacy is developing aUniversity Botanic Garden <strong>for</strong> use as amedicinal plant resource (V. Heywood,pers.comm.). Work is also underway inaffiliation with the Foundation <strong>for</strong> theRevitalisation of Local Health Traditions(FRLHT) in India on developing DNAmarkers <strong>for</strong> medicinal plants. (J. Hawkins,pers.comm.).EducationRightly hailed as a way of inspiring andmotivating action and public support,education about medicinal plants takesmany <strong>for</strong>ms; from educating endconsumers about the sources of theirmedicines to educating farmers and herbgatherers about the value of sustainableharvest. Botanic gardens have a key roleto play in educating the public about thevalue and conservation needs ofmedicinal plants.Target 14 of the GSPC calls <strong>for</strong>education and awareness about plantdiversity to be promoted.Marie Selby Botanic Garden in Floridais creating in<strong>for</strong>mation profiles <strong>for</strong> themedicinal plants in the garden, toinclude the conservation status of thespecies in the wild, geographicalin<strong>for</strong>mation, botanical characteristicsand ecology, uses to humans and partsof plants used, chemical compounds,history and folklore, re-affirming thelinks between plants and people(Tieghem, pers.comm.).Seven of the eight botanic gardens inthe South African National BiodiversityInstitute’s (SANBI) network of botanicgardens have demonstration gardensthat are used <strong>for</strong> education, display andresearch on indigenous traditional use(Xaba, pers.comm.).Several botanic gardens in the US <strong>for</strong>example, Denver, Brooklyn, NorthCarolina and New York as well as theRoyal Botanical Gardens in Canada offertraining courses in horticultural therapy.It has been well established that peoplerespond positively to green plants andcolorful flowers. Gardening offers relieffrom physical and cognitive limitations,reduces stress, gently exercises aging orarthritic joints, and stimulates memory.Krishna Mahavidyalaya Botanic Garden inIndia grows approximately 130 species ofmedicinal plants in pots, emphasizingthose used in indigenous systems ofmedicine. The plants are accompaniedby display notes including the commonname in various languages as well as itsuse as medicine and scientific data.Since the plants are in pots, a mobileexhibit has traveled extensively, creatingawareness and educating people abouttheir shared medicinal plant resource(Salunkhe, pers.comm.).The IB-UNAM Botanic Garden, Mexicoruns courses whereby ethnobotanistsshare their technical and botanicalexpertise while traditional healers sharetheir knowledge on the indigenous andritual use of plants. The in<strong>for</strong>mation isdisseminated by the botanic garden toother healers, housewives, professionalsand alternative health practitioners.In the UK, the Botanic Garden of Waleshas a ‘Physicians of the Myddfai’exhibition and displays traditionallyimportant medicinal plants whilst BristolZoological Gardens provides the locale<strong>for</strong> a series of courses and lectures onmedicinal plants.<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 17


Working with local authorities, OaxacaBotanic Garden in Mexico hasrecommended Guiacum coulteri beplanted in local parks and publicgardens, as well as making seedsavailable to local schools and communityorganizations (A.de Avila, pers.comm.).The Tasmania Herbarium in Australiaused its living collections to supportscreening by a large pharmaceuticalcompany searching <strong>for</strong> active medicinalcompounds, in accordance with accessand benefit sharing regulations(Papworth, pers.comm.).NetworkingNo single sector, public or private, canundertake the conservation of medicinalplants alone and the neutral nature ofbotanic gardens puts them in a goodposition to act as intermediaries betweenvarious commercial and scientific interests.The importance of enhancedcommunication and knowledge exchangebetween concerned parties has also beenrecognised by the GSPC, which statesthat networking can avoid duplication ofconservation ef<strong>for</strong>t, enable thedevelopment of common approaches,help strengthen links between differentsectors and ensure the co-ordination ofpolicy development at all levels.Target 16 of the GSPC calls <strong>for</strong> theestablishment and strengthening ofplant conservation networks.The Jardin Botânico da FundaçâoZoobotânica de Belo Horizonte in Brazilpartners with universities to study thechemical composition and biologicalactivites of local medicinal plants(Nogueira, pers.comm.).The Botanic Gardens of Adelaide inAustralia, as well as developingeducation programs <strong>for</strong> schools basedaround indigenous knowledge and thetraditional uses of plants, work closelywith hospitals on harmful plants andtoxicology (Christensen, pers.comm.).In situ conservationAs recognised by the CBD, in situconservation is the preferablemethodology, since ex situ conservationtends to take place outside the range stateof the target species. The preservation ofspecies in situ offers all the advantages ofallowing natural selection to act, whichcannot be recreated ex situ. Unless plantscan be conserved in their natural habitats,in variable breeding populations, they runthe risk of extinction.In reality, many species exist only aspart of ecosystems and cannotsurvive unless their ecosystems arepreserved along with as much aspossible of the biodiversity theycontain. Cistanche deserticola, <strong>for</strong>example, an important plant in TCM,is dependent on two fungi; Mycenaosmundicola (to draw nutrients fromthe soil and allow seed germination)and Armillaria mellea (which must beincorporated into the tuber tomaintain growth to maturity).Similarly, Cistanche deserticola isparasitic to the roots of the desertshrub Haloxylon spp. The Haloxylongenus is notoriously difficult tocultivate, and is also know as ‘coal ofthe desert’ because of its firewoodproperties. The conservation of thesespecies cannot be removed from thehabitats they exist within.Traditionally, in situ conservation hasinvolved the protection of species withintheir natural habitats in various <strong>for</strong>ms ofland set aside as nature reserves or otherprotected areas. This approach cordonsoff certain areas and restricts their use.Though often hampered by weaken<strong>for</strong>cement capacity, protected areasare of critical importance since we haveyet to master the sustainable use ofmedicinal plant resources in the wild.Botanic garden display including various aloes, which are commonly used <strong>for</strong>skin conditions.Botanic gardens are involved in themanagement of natural habitats in thisway, as well as carrying out field-work,such as wild population surveys.A priority <strong>for</strong> medicinal plant conservationis the carrying out of ecogeographicalsurveys, followed by proper targeted insitu species conservation with as manysamples of genetic (there<strong>for</strong>e chemical)variation as possible preserved(Heywood, pers.comm.).18<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens


NGO representatives but mostimportantly the rural populations ofpeople living near wild medicinal plantpopulations. Preferable methodologieswill improve the understanding of impactson the livelihoods of the poor of bothharvesting medicinal plants and ofmeasures to ensure the conservation andsustainable use of medicinal plants.Community-based conservationworkBotanic gardens are increasingly involvedin the development, implementation andsupport of local, community-basedprojects, <strong>for</strong> example using collections tosupport local initiatives in primaryhealthcare.Medicinal plant conservation is aboutplant resources, hence emphasising theidea of conservation not <strong>for</strong> conservation’ssake but <strong>for</strong> the conservation of resources<strong>for</strong> use (Hamilton, pers.comm.).Community-based conservationemphasises the things about these plantsthat give people drive to do somethingabout them i.e. concerns about health,money (income generation) and cultures(important religious elements, heritageprotection). Recent <strong>for</strong>estry research hasshown that, when their rights arerecognised, communities are moreeffective at protecting <strong>for</strong>ests thannational parks (Rights and ResourcesInitiative, 2007).However, response strategies designed toprovide incentives <strong>for</strong> biodiversityconservation by ensuring that local peoplebenefit from one or more component ofbiodiversity (such as products from asingle species) have proved very difficultto implement (MEA, 2005).Lophophora williamsii, used ritually inMexico <strong>for</strong> thousands of years.Community-based conservation mustthere<strong>for</strong>e be integrated with developmentat every level; from village to region toworld. A wide range of stakeholdersmust be engaged from the start; fromscientists to traders to government andThe Etnobotanica Paraguay project, runby the Conservatoire et JardinBotaniques de la Ville de Geneve, isresearching the use of local medicinalplants and running targeted educationcampaigns to encourage the use andprotection of appropriate species, aswell as setting up community gardensand looking at the best application ofthe plants.Malabar Botanic Garden in India ispromoting the cultivation of the state’snative medicinal plants, by giving trainingin relevant techniques to local farmers.Guidance is given on the medicinalplants‘ cultivation, storage and trade.In the last two years over 200 farmershave been trained, and a farmer’s societyhas been <strong>for</strong>med to share knowledgeand to promote the mass cultivation andtrade of medicinal plants. This hasprovided a valuable opportunity <strong>for</strong> thesefarmers to expand and diversify theircrops, safeguarding their incomes.At Nature Palace Botanic Garden inUganda the Poverty Alleviation andHealth Promotion through Conservationproject engaged 50 subsistencefarmers who are now cultivating raremedicinal plants <strong>for</strong> income generation.The farmers have <strong>for</strong>med anAssociation (the Kasanje Conservationand Development Association), which isnow engaged in a drive to recruit morefarmers (D. Nkwanga, pers.comm.).North Carolina Botanic Garden andthe North Carolina Department ofAgriculture collaborated on a project tomark Dionea muscipula plants growingin the wild. Roots are painted with adye that glows under ultra-violet light,enabling the identification of wildharvested specimens. This is proving adeterrent to would-be poachers, whoplucked thousands of Venus fly-trapsfrom the protected Green Swamp areain a single afternoon in 2005 (NatureConservancy, 2006).Aburi Botanical Garden in Ghana inpartnership with BGCI, the UNEPWorld Conservation Monitoring Centre,the Royal Botanic Garden Edinburghand the University of Ghana ran theConservation and Sustainable Use ofMedicinal plants in Ghana project. Thisproject aimed to improve communities’access to medicinal plants, and toencourage their sustainable use. It setup a 50 acre model Medicinal PlantGarden, based on community ethnobotanicalsurveys, which was plantedwith 1,361 medicinal plant seedlings,and also set up a plant nursery to hold5,000 medicinal plant seedlings <strong>for</strong>distribution to herbalists.The National Botanic Garden ofBelguim works closely with KisantuBotanic Garden in the Congo both oncommunity education and thepropagation of medicinal plants <strong>for</strong>distribution (Rammello, pers.comm).<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 19


7. Recommendations <strong>for</strong> medicinal plantconservation by botanic gardensThe questionnaire survey has provided awealth of in<strong>for</strong>mation on the ways botanicgardens can support medicinal plantconservation. These echo the pointsmade in the previous section, in whichcase studies from questionnaireresponses have already been highlighted.A strong majority of respondentsemphasised the role that botanic gardensplay in conservation education, and thecontinued importance of raisingawareness about medicinal plantresources. Also particularly highlightedwas the role of research and the need <strong>for</strong>botanic gardens to develop collaborativeventures, working with partner NGOs andlocal communities.Rescuing Aloe castanea from granite mining.Encephalartos ghellinctii, vulnerable in thewild, slow-growing and rare in cultivation.Prioritise speciesTaking into account the sheer number ofmedicinal plant species around the world(c.70,000) and the number which may bethreatened (c.15,000) comprehensive andconsistent in<strong>for</strong>mation on the threat statusof medicinal plants at a global level is notyet available. This limits the extent towhich a rational prioritisation can beundertaken <strong>for</strong> medicinal plantconservation.Logically, the in<strong>for</strong>mationrequired <strong>for</strong> such aprioritisation exercise is:i) which species are mostthreatened; ii) which speciesare most valuable in terms ofhealthcare and of livelihoodsand iii) our ability to conservethe species in question.Botanic gardens are wellplaced to define localpriorities. Globally, BGCI can assist byassessing the extent to which plants arealready in cultivation by botanic gardens,what their threat status is and (throughcollaboration with other organisations)what the priorities <strong>for</strong> practical action are.Annex 5 lists all the species that weresuggested to us as priority species <strong>for</strong>conservation action over the next 5 years,as well as their IUCN and CITES status.In most cases the in<strong>for</strong>mation providedreflects species of national concern asprovided by the respondents.We have also indicated whether thesespecies are held in botanic gardencollections. Several species werementioned more than once, and these35 priority species are presented first.BGCI will pay particular attention to workwith its member gardens to conservethese species (See Section 8 andAnnex 7).Prioritise actions1. ResearchIt is widely recognised that medicinal plantconservation is hampered by a lack ofgood quality in<strong>for</strong>mation. It is there<strong>for</strong>eessential to collect accurate data regardingplant population density in the wild in thepast and present, the current commercialdemand and future projections, methods ofcollection and threats to these plants.Botanic gardens are well placed toundertake research to determine thetaxonomy, propagation and managementtechniques <strong>for</strong> medicinal plants.20<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens


Specifically, the following research areaswere highlighted in questionnaireresponses;• Regionally up-to-date lists of speciesused <strong>for</strong> medicinal purposes wouldenhance the opportunity to use themsustainably.• Locally used medicinal plants can thenbe categorised according to their use,value, ecological characteristics andmanagement, by way of prioritisingspecies <strong>for</strong> conservation action.• Species-specific baseline data on thestatus of populations in the wild and onwhat entails a sustainable harvest limit,both culturally and commercially, isrequired <strong>for</strong> priority species (to includeharvesting techniques which aresuitable <strong>for</strong> village level use).2. EducateIt has often been argued that a majorreason <strong>for</strong> our failure to conserve naturalecosystems is that we do not realise howvaluable they are. In fact, a country’secosystems and its ecosystem servicesrepresent a capital asset. The benefitsthat could be attained through bettermanagement of this asset are poorlyreflected by conventional economicindicators, so this must be clearlydemonstrated in different ways.For medicinal plants; why should wildharvest be curtailed when it will alwaysbe the easiest option? Why shouldconsumers re-visit their consumptionhabits and make a decision on whichproducts they will use and which theywon’t? An educated public can influenceboth the pattern of trade and,optimistically, governmental decisions.Practical suggestions <strong>for</strong> educationalinitiatives included the following;• Botanic gardens should be aware ofthe medicinal properties of plantswithin their collections. Interpretationpanels can illustrate both the valuesand vulnerability of medicinal plantsand promote an understanding ofmedicinal plant conservation, effectingan attitudinal change about the use ofnatural resources and medicinal plants.Botanic gardens can pro-activelyimprove people’s access to thisin<strong>for</strong>mation.• Model gardens can be created to bedemonstration areas <strong>for</strong> people livingnear to threatened species <strong>for</strong>conservation knowledge. Stakeholderscan be taught appropriate ex situmanagement techniques such asdomestication, management and valueadding. Booklets can be prepared andcirculated on the latest cultivationmethods and post-harvestingprocesses <strong>for</strong> key species.• Targeted education campaigns canalso be linked to outreachprogrammes, <strong>for</strong> example to healthcare workers dealing with first linemedicinal aid, or with school botanicprojects. Mobile exhibits have beenshown to be particularly useful.3. CollaborateMuch mentioned in questionnaireresponses was the need <strong>for</strong> acollaborative approach to medicinal plantconservation and the recognition thatbotanic gardens are well placed tofacilitate this and add both key botanicalknowledge and key knowledge aboutlocal people, industries and landscapes.Key messages <strong>for</strong> botanic gardens were to:• Joint plan rather than work in isolation,check who else is doing what be<strong>for</strong>edeciding priorities.• Diversify working partners, <strong>for</strong> examplework with <strong>for</strong>estry, agriculture andhealth industries, as well as NGOs.• Develop regional approaches to themanagement of species occurring inneighbouring countries.• Develop joint outreach and extensionprogrammes and contribute to theseby bringing botanical expertise onspecific taxa.• In<strong>for</strong>m legislation and policydevelopment and assist with nationalimplementation and interpretation ofinternational statutes. For example,training Customs officials on theidentification of CITES listed medicinalplant parts and derivatives.• Encourage private sector support <strong>for</strong>sustainable and ethical sourcing.<strong>Plants</strong> <strong>for</strong> <strong>life</strong> 21


4. ConserveThe role of plant and seed collections as aconservation resource was widelyacknowledged as an important piece ofthe conservation jigsaw puzzle. It wasemphasised that ex situ methods aremade more relevant when they feeddirectly and specifically into targeted insitu conservation, and that this shouldbecome a normal partnership. Seedbanking was frequently cited inquestionnaire responses as a vital backupto other conservation methodologies,and one that should be supported andexpanded <strong>for</strong> medicinal plants specifically,since most ef<strong>for</strong>ts have been directed tocrops thus far. Further, climate changescience is turning its attention to thepredicted effects of temperature rise onindividual plant species. The alteration ofa species’ environmental niche will in turnaffect whole ecosystems; habitats willshift and their composition change.Ex situ collections that attempt to recreatehabitats become even more relevant inthis light.Botanic gardens should there<strong>for</strong>e:• Maintain and develop living collectionsof local medicinal plants and makethem available <strong>for</strong> teaching andresearch use.• Set-up and maintain seed andgermplasm banks, specifically <strong>for</strong> localmedicinal plants and those criticallyendangered. Ensure that the best andmost current seed conservationtechnologies are used, to ensure longtermpreservation.• Foster ecological and floristic studies insites of origin of plants.• Maintain familiarity and compliancewith regulations, <strong>for</strong> example CITES,and with the conservation status ofmedicinal plant holdings via, <strong>for</strong>example, the IUCN Red List.• Contribute to the development andtesting of conservation methodologies.5. Preserve indigenous knowledgeIn 2004 the United Nations Conferenceon Trade and Development (UNCTAD)warned that a biodiversity crisis is beingaccompanied by a cultural diversity crisisand the weakening of the customary lawsthat traditionally regulated the use ofnatural resources. The growingawareness of loss of indigenousknowledge and the implications of thiswas reflected in questionnaire responses.• Target 13 of the GSPC calls <strong>for</strong> thedecline of plant resources andassociated indigenous knowledge thatsupport livelihoods to be halted, sinceboth physical habitat and ancientknowledge, once lost, will be gone<strong>for</strong>ever.• There are inherent conservation valuesin the way plants were collected <strong>for</strong>traditional healing, many of which havenow fallen out of use. In Zimbabwe,<strong>for</strong> example, the collecting of bark,roots, branches etc. from a plant thatshowed signs of having been collectedfrom by another n’anga (traditionalhealer) was prohibited. It was believedthat when a n’anga used a plant totreat a patient, the patient’s diseasewas transferred into that plant.When another n’anga subsequentlyused the same plant to treat a patient,the disease of the previous patientwould be transferred to the newpatient. This belief ensured that theplant recovered from the effects ofcollection (Mavi and Shava, 1997).• There have been clashes betweentraditional healers and externalorganisations, based around theownership of indigenous knowledge.Botanic gardens are likely to havedetailed specific knowledge about thelandscapes, people and flora of anarea and are well-placed to buildcommunity links and to help with thedocumentation of traditional knowledgeon medicinal plants that is available inthe public domain.• There are simple ways botanic gardenscan collect and promote indigenousknowledge. For more in<strong>for</strong>mation onthe collection of indigenous knowledgego to www.kew.org/ethnomedica/.6. Develop alternatives to wild harvest,technology transferAnother key questionnaire response,emphasised again and again, was therole of community involvement inconservation. This is imperative at allstages of project development andimplementation. At a local level botanicgardens can provide communities withvaluable horticultural expertise andmarket in<strong>for</strong>mation. The transfer ofcultivation methodologies to farmers andother stakeholders via training initiativesshould be encouraged, as should thedevelopment of harvester organisationsand best practice horticultural knowledgeshared between these. Additionally,investments in technology transfer,research, training and capacity building,can make the private sector voluntarilyrespond to environmental management.• A recent study of 150 traditional healersin South Africa found that 72% saidthey would appreciate proper trainingon how to domesticate frequently usedmedicinal plants (Manzini, 2005).• During storage considerable amountsof medicinal plants are wasted due tohumidity, insect attacks, inappropriatestorage facilities and lack of awarenesson the part of collectors. (Hamuyan etal., 2006).22<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens


8. Towards an action plan <strong>for</strong> medicinalplant conservation by BGCI• Link this data to the PlantSearchdatabase and make available via anin<strong>for</strong>mation portal. Continue todevelop PlantSearch as a means ofmonitoring and recording medicinalplants in botanic garden collections,as well as identifying regions where thisis a priority.• Coordinate the collection of casestudies, analysis of best practice andsharing of lessons, helping to improveboth collection management andconservation practice.Use the in<strong>for</strong>mation available <strong>for</strong>educational purposes (see below).2. Provide education and trainingmaterials on medicinal plants and theirconservation• Identify and publish case studies aboutsuccess in medicinal plant conservation.• Provide in<strong>for</strong>mation and educationalmaterials about relevant policy andscientific issues, <strong>for</strong> example the ISSC-MAP and CITES and ABSrequirements.• Develop models and outreach materials<strong>for</strong> 35 priority species relevant to alllevels of botanic garden visitors, staffand volunteers, as well as <strong>for</strong> donorsand decision makers.The role of BGCI is to support and enablebotanic gardens to act on therecommendations made <strong>for</strong> medicinalplant conservation in the previous sectionof this report. The questionnaire surveyand consultation during this projectresulted in a very wide range ofsuggestions of activities BGCI couldundertake. These suggestions, togetherwith discussions between BGCI staff,member gardens and other medicinalplant conservation agencies have led tothe development of an action plan <strong>for</strong>BGCI’s medicinal plant conservation work,as well as the identification of key partners<strong>for</strong> future activities, such as TRAFFIC,the IUCN/SSC MPSG and Plant<strong>life</strong>International, as well as various nationaland local organisations and stakeholders.Activities at the global level1. In<strong>for</strong>mation gathering andawareness raising <strong>for</strong> over 400suggested priority species (at Annex 5)• Collect detailed in<strong>for</strong>mation on the exsitu conservation status of these speciesand work towards ensuring that all aresecure in ex situ collections (at least 5botanic gardens), with well-documented,diverse genetic representation.Develop education materials that in<strong>for</strong>mkey stakeholders about the need <strong>for</strong>botanic gardens and their role inmedicinal plant conservation.3. Promote the role of botanic gardensin CITESQuestionnaire responses to CITES issuesfavoured the promotion of appropriatecultivation of CITES listed species andlocal community participation in this,incentivising compliance andconservation without threateninglivelihoods.

Annex 3 – Medicinal plants questionnaireSafety Nets <strong>for</strong> Medicinal <strong>Plants</strong> ProjectQuestionnaireLinking more than 800 botanic gardens in 118 countries BGCI(www.bgci.org) <strong>for</strong>ms the world’s largest plant conservationnetwork, with a mission to mobilise botanic gardens and engagepartners in securing plant diversity <strong>for</strong> the well-being of peopleand the planet. One of the specific aims of our 5 year plan(2007 – 2012) is to enhance the conservation of threatenedmedicinal and nutritious plants to address human well-beingand livelihood issues as a contribution towards Targets 3 and 13of the GSPC.To this end, we have begun to identify the threatened plantspecies held in botanic gardens according to the BGCIPlantSearch database and we are working to improve thein<strong>for</strong>mation held so that it can be used as a planning tool. Wehave also identified several successful models of medicinal plantconservation work undertaken by botanic gardens. Theyinclude:• Working with communities to document and use indigenousknowledge• Educating on the value and used of sustainably harvestedmedicinal plants• Collecting and developing gene pools of wild stock plants• Research to discover and investigate medicinal plantproperties• Using collections to support local initiatives in primaryhealthcare, particularly in developing countries• Using collections to support screening programmes <strong>for</strong>pharmaceutical companies, in accordance with guidelines onaccess and benefit sharing, and to assay the value and safetyof particular medicines• Improving the agronomy of cultivated medicinal plants• Cultivating medicinal plants, to tackle unsustainable harvestand improve ease of harvest• Practice of horticultural therapy, using plants and gardeningto treat mental and physical disorders• Educating end consumers and supporting standard setting <strong>for</strong>medicinal plant productionNow, in order to successfully match medicinal plantconservation needs with the capabilities of gardens we wouldgreatly value your input. This will help to define priorities <strong>for</strong>both in situ and ex situ conservation programmes and tofacilitate best practice and priority activities <strong>for</strong> implementation.5. We want to help botanic gardens help medicinal plants.Where do you think BGCI should focus our capacity buildingover the next 5 years?There are a range of resources available on medicinal plants andconservation programmes but little specifically targeted atbotanic gardens. We want to maximise the potential <strong>for</strong> skill,best practice and knowledge sharing.Your input will help focus conservation ef<strong>for</strong>ts and feed into theproduction of a new report and action plan containing casestudies and best practice to utilise the skills of botanic gardensin conserving threatened medicinal plant species.Optional contact details:Your name:Your institution:Email:Does your institution currently run any projects withmedicinal plants?

Within the 35 priority list 5 genera were suggested: Aloe spp.,Aquilaria spp., Cinchona spp., Hoodia spp. and Panax spp.These have been discounted from the above graph and lookedat separately. For Aloes, Aquilarias and Cinchonas only thosespecies that have been assessed as CR, EN or VU on the 2007Red List of Threatened Species have been screened against thePlantSearch database. For Panax spp. we have used both the2007 Red Listed species and those specifically suggested to usas of conservation priority.

A taxon is presumed Extinctwhen exhaustive surveys in known and/orexpected habitat, at appropriate times(diurnal, seasonal, annual), throughout itshistoric range have failed to record anindividual. Surveys should be over a timeframe appropriate to the taxon’s <strong>life</strong> cycleand <strong>life</strong> <strong>for</strong>m.EW – Extinct in the wildAdequate dataA taxon is Extinct in the Wild when it isknown only to survive in cultivation, incaptivity or as a naturalized population (orpopulations) well outside the past range.A taxon is presumed Extinct in the Wildwhen exhaustive surveys in known and/orexpected habitat, at appropriate times(diurnal, seasonal, annual), throughout itshistoric range have failed to record anindividual. Surveys should be over a timeframe appropriate to the taxon’s <strong>life</strong> cycleand <strong>life</strong> <strong>for</strong>m.CR – Critically EndangeredNot Evaluated (NE)A taxon is Critically Endangered when thebest available evidence indicates that itmeets any of the criteria <strong>for</strong> CriticallyEndangered and it is there<strong>for</strong>e consideredto be facing an extremely high risk ofextinction in the wild.ThreatenedData Deficient (DD)EN - EndangeredA taxon is Endangered when the bestavailable evidence indicates that it meetsany of the criteria <strong>for</strong> Endangered and itis there<strong>for</strong>e considered to be facing avery high risk of extinction in the wild.VU - VulnerableEndangered (EN)Vulnerable (VU)Near Threatened (NT)Least Concern (LC)A taxon is Vulnerable when the bestavailable evidence indicates that it meetsany of the criteria <strong>for</strong> Vulnerable, and it isthere<strong>for</strong>e considered to be facing a highrisk of extinction in the wild.NT – Near threatenedA taxon is Near Threatened when it hasbeen evaluated against the criteria butdoes not qualify <strong>for</strong> Critically Endangered,Endangered or Vulnerable now, but isclose to qualifying <strong>for</strong> or is likely to qualify<strong>for</strong> a threatened category in the nearfuture.LR – Lower risk (from the 1994Categories and Criteria, version 2.3)A taxon is Lower Risk when it has beenevaluated, does not satisfy the criteria <strong>for</strong>any of the categories CriticallyEndangered, Endangered or Vulnerable.Taxa included in the Lower Risk categorycan be separated into threesubcategories:1. Conservation Dependent (cd). Taxawhich are the focus of a continuingtaxon-specific or habitat-specificconservation programme targetedtowards the taxon in question, thecessation of which would result in thetaxon qualifying <strong>for</strong> one of thethreatened categories above within aperiod of five years.2. Near Threatened (nt). Taxa which donot qualify <strong>for</strong> ConservationDependent, but which are close toqualifying <strong>for</strong> Vulnerable.3. Least Concern (lc). Taxa which do notqualify <strong>for</strong> Conservation Dependent orNear Threatened.LC – Least concernA taxon is Least Concern when it hasbeen evaluated against the criteria anddoes not qualify <strong>for</strong> Critically Endangered,Endangered, Vulnerable or NearThreatened. Widespread and abundanttaxa are included in this category.DD – Data deficientA taxon is Data Deficient when there isinadequate in<strong>for</strong>mation to make a direct,or indirect, assessment of its risk ofextinction based on its distribution and/orpopulation status. A taxon in thiscategory may be well studied, and itsbiology well known, but appropriate dataon abundance and/or distribution arelacking. Data Deficient is there<strong>for</strong>e not acategory of threat. Listing of taxa in thiscategory indicates that more in<strong>for</strong>mationis required and acknowledges thepossibility that future research will showthat threatened classification isappropriate. It is important to makepositive use of whatever data areavailable. In many cases great careshould be exercised in choosing betweenDD and a threatened status. If the rangeof a taxon is suspected to be relativelycircumscribed, and a considerable periodof time has elapsed since the last recordof the taxon, threatened status may wellbe justified.<strong>Plants</strong> <strong>for</strong> <strong>life</strong>: Medicinal plant conservation and botanic gardens 45
