FOREWORD<br />

Interim Recovery Plan No. 65<br />

Interim Recovery Plans (IRPs) are developed within the framew<strong>or</strong>k laid down in Department <strong>of</strong><br />

Conservation and Land Management (CALM) Policy Statements Nos 44 and 50<br />

IRPs outline the recovery actions that are required to urgently address those threatening processes most<br />

affecting the ongoing survival <strong>of</strong> threatened taxa <strong>or</strong> ecological communities, and begin the recovery<br />

process.<br />

CALM is committed to ensuring that Critically Endangered, and where appropriate and feasible, other<br />

threatened ecological communities are conserved through the preparation and implementation <strong>of</strong><br />

Recovery Plans <strong>or</strong> Interim Recovery Plans. CALM will also ensure that conservation action commences<br />

as soon as possible and always within three years <strong>of</strong> end<strong>or</strong>sement <strong>of</strong> Endangered rank <strong>by</strong> CALM's<br />

Direct<strong>or</strong> <strong>of</strong> Nature Conservation.<br />

This Interim Recovery Plan will operate from 11 September 2000 but will remain in f<strong>or</strong>ce until<br />

withdrawn <strong>or</strong> replaced.<br />

The provision <strong>of</strong> funds identified in this Interim Recovery Plan is dependent on budgetary and other<br />

constraints affecting CALM, as well as the need to address other pri<strong>or</strong>ities.<br />

Inf<strong>or</strong>mation in this IRP was accurate at 18 August 2000.<br />

1 BACKGROUND<br />

Hist<strong>or</strong>y, defining characteristics <strong>of</strong> ecological community, and conservation significance<br />

Noondine (= Coomberdale) chert is a discontinuous, narrow (up to 14 km wide) band <strong>of</strong> the Mo<strong>or</strong>a<br />

group <strong>of</strong> Proterozoic rocks stretching from Carnamah to Mo<strong>or</strong>a (Baxter and Lipple 1985, Carter and<br />

Lipple 1982). The Coomberdale Fl<strong>or</strong>istic Region c<strong>or</strong>responds to the discontinuous, narrow (~2-10 km<br />

wide) outcrop <strong>of</strong> Noondine chert from Jingemia to Mo<strong>or</strong>a with the largest most extensive outcrop<br />

between Coomberdale and Dalaroo (Carter and Lipple 1982, Griffin 1992).<br />

Three closely related vegetation sub-types occur on the exposed chert ridges and gravelly slopes <strong>of</strong> the<br />

chert hills in the Coomberdale Fl<strong>or</strong>istic Region that are recognisably different from other vegetation<br />

types within this fl<strong>or</strong>istic region and other fl<strong>or</strong>istic regions (Griffin 1992, 1994). These consist <strong>of</strong> dense<br />

heath <strong>dominated</strong> <strong>by</strong> <strong>Regelia</strong> <strong>megacephala</strong> <strong>or</strong> Allocasuarina campestris on the exposed chert ridges<br />

(sub-type 1); <strong>or</strong> dense heath <strong>or</strong> open low woodland over dense to mid-dense heath <strong>dominated</strong> <strong>by</strong><br />

<strong>Kunzea</strong> praestans (sub-type 2) <strong>or</strong> Allocasuarina campestris (sub-type 3) on shallow loamy rocky soil<br />

over chert on the slopes and ridges (Table 1). One <strong>or</strong> m<strong>or</strong>e <strong>of</strong> Dryandra fraseri var. fraseri, Dryandra<br />

sessilis, Hibbertia subvaginata, Xanth<strong>or</strong>rhoea drummondii, Melaleuca sp., Calothamnus quadrifidus<br />

and Calytrix leschenaultii are common to all sub-types.<br />

Interim Recovery Plan No. 65<br />

The chert substrate is highly restricted and there are currently only 8 known occurrences <strong>of</strong> the heath<br />

community. The maj<strong>or</strong> threats to the community are weed invasion, grazing, inappropriate fire regimes,<br />

clearing and mining.<br />

Description <strong>of</strong> Occurrences<br />

All the known occurrences are located in the Shire <strong>of</strong> Mo<strong>or</strong>a on the range <strong>of</strong> Noondine chert hills that<br />

extend discontinuously from Jingemia south to Mo<strong>or</strong>a, ie. the Coomberdale Fl<strong>or</strong>istic Region. Table 3<br />

summarises the occurrence inf<strong>or</strong>mation.<br />

Occurrence 1 is spread across 3 freehold properties 12 km n<strong>or</strong>th <strong>of</strong> Mo<strong>or</strong>a. The Threatened Ecological<br />

Community (TEC) comprises 152 ha <strong>of</strong> the 251 ha <strong>of</strong> remnant vegetation. The remaining vegetation<br />

comprises mixed low heath and vestiges <strong>of</strong> the once widespread Eucalyptus loxophleba woodland on<br />

the plains and valley flo<strong>or</strong>s (Griffin 1992). The n<strong>or</strong>thern p<strong>or</strong>tion <strong>of</strong> Occurrence 1 (61 ha) is on private<br />

land and is only known to have been inspected once to locate <strong>Regelia</strong> <strong>megacephala</strong> (Burgman 1983).<br />

The central p<strong>or</strong>tion <strong>of</strong> Occurrence 1 (79 ha, known as ‘Cairn Hill’) is owned freehold <strong>by</strong> Westrail and is<br />

apparently the most intact p<strong>or</strong>tion. The Mo<strong>or</strong>a Shire has, until recently, been extracting gravel from the<br />

base <strong>of</strong> this p<strong>or</strong>tion <strong>of</strong> the hills which has extended up into the edges <strong>of</strong> the heath community. Two<br />

radio and television towers are located on the highest p<strong>or</strong>tion <strong>of</strong> the hills in the centre <strong>of</strong> the Westrail<br />

land, and low land on the eastern p<strong>or</strong>tion <strong>of</strong> this land is currently under a grazing lease. There is a<br />

prospecting lease over much <strong>of</strong> the central and n<strong>or</strong>thern p<strong>or</strong>tions <strong>of</strong> Occurrence 1 f<strong>or</strong> the purposes <strong>of</strong><br />

extracting chert with expl<strong>or</strong>ation tracks over a segment <strong>of</strong> the n<strong>or</strong>thern p<strong>or</strong>tion.<br />

The southern and smallest p<strong>or</strong>tion (12 ha) <strong>of</strong> Occurrence 1 is located on private land that is heavily<br />

grazed with vegetation only on the summits. Occurrence 2 (17 ha) occurs on the same property and<br />

comprises m<strong>or</strong>e <strong>of</strong> the TEC fragmented into six p<strong>or</strong>tions, with the largest site 7 ha and the smallest 0.5<br />

ha.<br />

Occurrence 3 is located on private land 7 km n<strong>or</strong>th-east <strong>of</strong> Mo<strong>or</strong>a. The TEC comprises 25 ha <strong>of</strong> the 54<br />

ha <strong>of</strong> remnant vegetation surrounded <strong>by</strong> cropping land; the remainder <strong>of</strong> the remnant vegetation<br />

comprising Eucalyptus loxophleba and E. salmonophloia woodland in the lower areas. The occurrence<br />

has not been grazed f<strong>or</strong> at least seven years and has recently been fenced under the Remnant Vegetation<br />

Protection Scheme.<br />

Interim Recovery Plan No. 65<br />

Occurrence 4 is located on private land 0.25 km n<strong>or</strong>th <strong>of</strong> Occurrence 1. The TEC <strong>or</strong>iginally comprised<br />

60 ha <strong>of</strong> the 95 ha <strong>of</strong> remnant vegetation - surrounded <strong>by</strong> cropping land – but 45 ha was mined f<strong>or</strong><br />

chert. Expl<strong>or</strong>ation tracks traverse the rest <strong>of</strong> the occurrence and the remnant vegetation.<br />

Occurrence 5 is the largest occurrence and is located on private land 0.5 km n<strong>or</strong>th <strong>of</strong> occurrence 4. As<br />

with four previously menti<strong>one</strong>d occurrences, the three sub types are represented on this occurrence as<br />

well as an Acacia acuminata thicket on top <strong>of</strong> <strong>one</strong> ridge and a Eucalyptus loxophleba and E. wandoo<br />

woodland on the lower west side. The occurrence – spread across 3 freehold properties – is fragmented;<br />

with cropping and grazing lands between hills and on the lower slopes. Only 21 ha <strong>of</strong> the occurrence<br />

has been fenced f<strong>or</strong> conservation and covenanted under the Remnant Vegetation Protection Scheme. In<br />

1981 a fire swept through the south eastern side <strong>of</strong> the occurrence affecting the fenced p<strong>or</strong>tion and the<br />

hill <strong>dominated</strong> <strong>by</strong> Acacia acuminata.<br />

Of the total 668 ha <strong>of</strong> the community across all occurrences, 60 ha occur in two reserves. Occurrence 6<br />

(10 ha) is in a water reserve 1 km east <strong>of</strong> Mo<strong>or</strong>a - surrounded <strong>by</strong> agricultural land - managed <strong>by</strong> the<br />

Water C<strong>or</strong>p<strong>or</strong>ation. Only sub type 3 is represented in this reserve, although <strong>Regelia</strong> <strong>megacephala</strong> was<br />

thought to occur on the reserve (T. Griffin, personal communication 1 ). Much <strong>of</strong> the reserve has been<br />

cleared f<strong>or</strong> gravel extraction and access tracks, and has been trampled through recreational use.<br />

Occurrence 7 includes the only p<strong>or</strong>tion <strong>of</strong> the TEC (sub type 3 only) in conservation reserve - 50 ha in<br />

Watheroo National Park vested in the National Parks and Nature Conservation Auth<strong>or</strong>ity and managed<br />

<strong>by</strong> the Department <strong>of</strong> Conservation and Land Management (CALM). The remainder <strong>of</strong> the occurrence<br />

is on private land. The National Park p<strong>or</strong>tion part <strong>of</strong> it is on the edge <strong>of</strong> the park and b<strong>or</strong>ders a gravel<br />

road. The rest is surrounded <strong>by</strong> extensive, intact Eucalyptus loxophleba and mallee woodlands. The<br />

privately owned p<strong>or</strong>tions are surrounded <strong>by</strong> agricultural land and are currently grazed.<br />

Occurrence 8 is located on private land 2 km west <strong>of</strong> occurrence 4. The TEC comprises 15 ha <strong>of</strong> the 35<br />

ha <strong>of</strong> remnant vegetation and the remainder is Eucalyptus loxophleba, E. salmonophloia and E. wandoo<br />

woodland.<br />

Critical Habitat<br />

Critical habitat is habitat identified as being critical to the survival <strong>of</strong> a listed threatened species <strong>or</strong> listed<br />

threatened ecological community. Habitat is defined as the biophysical medium <strong>or</strong> media (a) occupied<br />

(continuously, periodically <strong>or</strong> occasionally) <strong>by</strong> an <strong>or</strong>ganism <strong>or</strong> group <strong>of</strong> <strong>or</strong>ganisms; <strong>or</strong> (b) once occupied<br />

(continuously, periodically <strong>or</strong> occasionally) <strong>by</strong> an <strong>or</strong>ganism, <strong>or</strong> group <strong>of</strong> <strong>or</strong>ganisms, and into which<br />

<strong>or</strong>ganisms <strong>of</strong> that kind that the potential to be reintroduced. (sections 207A and 528 <strong>of</strong> Commonwealth<br />

Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act)).<br />

The critical habitat f<strong>or</strong> the heath community on the chert hills <strong>of</strong> the Coomberdale fl<strong>or</strong>istic region<br />

comprises the area <strong>of</strong> occupancy <strong>of</strong> the known occurrences c<strong>or</strong>responding to the outcrop <strong>of</strong> Noondine<br />

chert from Jingemia to Mo<strong>or</strong>a (Carter and Lipple 1982).<br />

Biological and ecological characteristics<br />

The fl<strong>or</strong>istic composition <strong>of</strong> the heath community is assumed to c<strong>or</strong>respond to the soil/substrate types<br />

and depths: <strong>Regelia</strong> <strong>megacephala</strong>, f<strong>or</strong> example, is only found where chert is exposed at the summit <strong>of</strong><br />

the hills. Otherwise, little is known <strong>of</strong> the biology and ecology <strong>of</strong> the community and gaining m<strong>or</strong>e<br />

inf<strong>or</strong>mation is a pri<strong>or</strong>ity in this Interim Recovery Plan.<br />

Threatening processes<br />

Interim Recovery Plan No. 65<br />

Only eight occurrences are currently known. With the exception <strong>of</strong> the occurrence within the National<br />

Park (Occurrence 7), all the other occurrences are surrounded <strong>by</strong> agricultural land – many with very<br />

little <strong>or</strong> no native vegetation buffer (eg. Occurrence 2 is fragmented into six small areas with no<br />

vegetation on the lower slopes and the valleys). Of the three vegetation sub-types that make up the<br />

community, only sub-type 3 is in a conservation reserve (in the National Park). Potential and current<br />

threatening processes to individual occurrences were summarised in Table 3 and are elab<strong>or</strong>ated as<br />

follows:<br />

Clearing<br />

Clearing f<strong>or</strong> agriculture in the Shire <strong>of</strong> Mo<strong>or</strong>a has been extensive with some 85% <strong>of</strong> vegetation in the<br />

area cleared (B. Lullfitz, personal communication 2 ). New proposals to clear <strong>one</strong> ha <strong>or</strong> m<strong>or</strong>e <strong>of</strong> any<br />

occurrences, and/<strong>or</strong> <strong>of</strong> the surrounding vegetation, <strong>of</strong> this community on private land would be subject<br />

to assessment in acc<strong>or</strong>dance with the Mem<strong>or</strong>andum <strong>of</strong> Understanding f<strong>or</strong> the protection <strong>of</strong> remnant<br />

vegetation on private land in the agricultural region <strong>of</strong> Western Australia (Government <strong>of</strong> Western<br />

Australia 1997)..<br />

Grazing<br />

All occurrences have been <strong>or</strong> are actively grazed. Grazing has caused alterations to the species<br />

composition <strong>of</strong> a number <strong>of</strong> the occurrences <strong>by</strong> the selective grazing <strong>of</strong> edible species, the introduction<br />

<strong>of</strong> weeds and nutrients, trampling and general disturbance.<br />

Weed invasion<br />

Weeds can have significant impacts on a community through competition with the native species,<br />

prevention <strong>of</strong> regeneration and alteration <strong>of</strong> fire regimes (Hobbs and Mo<strong>one</strong>y 1993). Disturbances such<br />

as fires and grazing can predispose areas to weed invasion if weed propagules are present. All <strong>of</strong> the<br />

occurrences <strong>of</strong> this community are close to agricultural areas that act as weed sources, and would be<br />

vulnerable to weed invasion following any disturbance. At present, weed levels in occurrences 2, 4, 5<br />

and 6 are high, but still quite low in the other occurrences.<br />

Altered fire regimes<br />

Fire can cause alterations to the species composition <strong>by</strong> increasing the number <strong>of</strong> weeds. As well, an<br />

increase in the frequency <strong>of</strong> fire can prevent species from completing growth and reproductive cycles.<br />

The risk <strong>of</strong> frequent fire to all occurrences is increased <strong>by</strong> the presence <strong>of</strong> grassy weeds in the<br />

underst<strong>or</strong>ey, as they are likely to be m<strong>or</strong>e flammable than many <strong>of</strong> the <strong>or</strong>iginal native species in the<br />

underst<strong>or</strong>ey. A fire swept through Occurrence 5 in 1981 seemingly damaging the community such that<br />

some <strong>of</strong> the species have still not recovered, including the <strong>Regelia</strong> <strong>megacephala</strong> (G. Ridgeway,<br />

personal communication 3 ). No post fire assessment, however, has been carried out to confirm and<br />

determine the fact<strong>or</strong>s responsible f<strong>or</strong> the apparent loss <strong>of</strong> species.<br />

Mining<br />

Plants that are reliant on the chert substrate are unlikely to regenerate once the chert is removed from<br />

the soil pr<strong>of</strong>ile. Regeneration techniques such as returning the topsoil and controlling weeds may be<br />

useful in reducing native species loss, however unless all species reliant on chert are identified<br />

regeneration may not be enough to return the community to anything approaching its <strong>or</strong>iginal state.<br />

Occurrence 4 has been extensively mined f<strong>or</strong> chert, and there are applications f<strong>or</strong> mining on Occurrence<br />

1. The company responsible f<strong>or</strong> mining Occurrence 4 has rep<strong>or</strong>tedly successfully cultivated and reintroduced<br />

<strong>Regelia</strong> <strong>megacephala</strong> f<strong>or</strong> use in rehabilitation (L. Doust, personal communication 4 ) but there<br />

is no inf<strong>or</strong>mation on the successful regeneration <strong>of</strong> the other comp<strong>one</strong>nts <strong>of</strong> the community.<br />

Mining proposals would be subject to assessment <strong>by</strong> the Environmental Protection Auth<strong>or</strong>ity in<br />

acc<strong>or</strong>dance with the Environmental Protection Act 1986.<br />

Guide f<strong>or</strong> decision-makers<br />

Section 1 provides details <strong>of</strong> current and possible future threats. Developments in the immediate<br />

vicinity <strong>of</strong> the occurrences require assessment. No developments should be approved unless the<br />

prop<strong>one</strong>nts can demonstrate that they will have no significant impact on the ecological community.<br />

Current status<br />

The ‘<strong>Heath</strong> <strong>dominated</strong> <strong>by</strong> <strong>one</strong> <strong>or</strong> m<strong>or</strong>e <strong>of</strong> <strong>Regelia</strong> <strong>megacephala</strong>, <strong>Kunzea</strong> praestans and Allocasuarina<br />

campestris on the ridges and slopes <strong>of</strong> the chert (quartzite) hills <strong>of</strong> the Coomberdale fl<strong>or</strong>istic region’<br />

community meets the following criteria f<strong>or</strong> Endangered (EN) ecological communities:<br />

B) Current distribution is limited, and<br />

ii) There are few occurrences, each <strong>of</strong> which is small and/<strong>or</strong> isolated and all <strong>or</strong> most<br />

occurrences are very vulnerable to known threatening processes<br />

Recovery strategy<br />

To devise, in close liaison with landholders and land managers, recovery actions f<strong>or</strong> all known<br />

occurrences, and promote their conservation.<br />

To conduct appropriate research into the ecology <strong>of</strong> the community to develop further understanding<br />

about the management actions required to maintain <strong>or</strong> improve its condition.<br />

2 RECOVERY AIM AND CRITERIA<br />

Aim<br />

• To improve the status <strong>of</strong> the heath community <strong>by</strong> protecting and maintaining the known<br />

occurrences, and reducing the level <strong>of</strong> threat so that the community will not become Critically<br />

Endangered.<br />

• To locate m<strong>or</strong>e occurrences and promote their protection, maintenance and recovery.<br />

Criteria f<strong>or</strong> success<br />

• Maintenance <strong>of</strong> the diversity and composition <strong>of</strong> the native species in the community.<br />

• An increase in the area <strong>of</strong> this community under conservation management.<br />

• Improvement in terms <strong>of</strong> reduction <strong>of</strong> threatening processes as defined in this document.<br />

Criterion f<strong>or</strong> failure<br />

Interim Recovery Plan No. 65<br />

• Significant loss <strong>of</strong> area <strong>or</strong> further modification <strong>of</strong> occurrences <strong>of</strong> the threatened ecological<br />

community.<br />

3 RECOVERY ACTIONS<br />

All but <strong>one</strong> <strong>of</strong> the occurrences are on land not managed <strong>by</strong> CALM. All land managers/owners have<br />

been notified <strong>of</strong> the imp<strong>or</strong>tance <strong>of</strong> the community and their cooperation will be sought to ensure that<br />

management activities do not affect the occurrences. Permission and cooperation will be sought from<br />

the appropriate land managers/owners pri<strong>or</strong> to any recovery actions being taken.<br />

3.1 Establish a Recovery Team<br />

The Mo<strong>or</strong>a District Threatened Fl<strong>or</strong>a Recovery Team will be the recovery team f<strong>or</strong> this community.<br />

The team will give consideration to including members to represent landholders. The Recovery Team<br />

will continue to rep<strong>or</strong>t annually to CALM’s C<strong>or</strong>p<strong>or</strong>ate Executive.<br />

Action: Establish a Recovery Team<br />

Responsibility: Mo<strong>or</strong>a District Threatened Fl<strong>or</strong>a Recovery Team (MTFRT)<br />

Estimated cost: $Nil<br />

Completion date: Completed<br />

3.2 Clarify the extent <strong>of</strong> the community and locate m<strong>or</strong>e occurrences<br />

The best quality colour aerial photographs (stereoscopic pairs) may assist in selecting likely sites, as<br />

would geological maps. An appropriate starting point would be areas <strong>of</strong> Noondine chert between<br />

Coomberdale and Watheroo. Field surveys (ground-truthing) will confirm their status. New occurrences<br />

should be added to the threatened ecological community (TECs) database as recommended in English<br />

and Blyth (1999).<br />

Action: Clarify the extent <strong>of</strong> the community and locate m<strong>or</strong>e occurrences<br />

Responsibility: CALM (WATSCU)<br />

Estimated cost: $3,000<br />

Completion date: Year 1<br />

3.3 Monit<strong>or</strong> the extent and boundaries <strong>of</strong> the community<br />

Monit<strong>or</strong> the extent, and determine and compare the condition <strong>of</strong> the known occurrences and any other<br />

identified occurrences (refer recovery action 3.2). The boundary <strong>of</strong> the occurrences should be monit<strong>or</strong>ed<br />

regularly and can be determined from current aerial photographs and annual ground-truthing. This<br />

inf<strong>or</strong>mation should be added to the threatened ecological community (TECs) database as recommended<br />

in English and Blyth (1999).<br />

Action: Monit<strong>or</strong> the extent and boundaries <strong>of</strong> the community<br />

Responsibility: CALM (WATSCU) f<strong>or</strong> initial monit<strong>or</strong>ing and MTFRT f<strong>or</strong> continuity<br />

Estimated cost: $2,000 f<strong>or</strong> the initial monit<strong>or</strong>ing ($500 per year f<strong>or</strong> subsequent monit<strong>or</strong>ing)<br />

Completion date: Ongoing<br />

Interim Recovery Plan No. 65<br />

3.4 Design and implement a program f<strong>or</strong> monit<strong>or</strong>ing the fl<strong>or</strong>a <strong>of</strong> the heath community<br />

Data collected should include plant species diversity, species richness and weed levels. Occurrences<br />

should be monit<strong>or</strong>ed regularly to provide inf<strong>or</strong>mation on condition. The program could include<br />

installing permanent quadrats and taking photographs <strong>of</strong> the same area. This inf<strong>or</strong>mation should be<br />

added to the threatened ecological community database (TECs) as recommended in English and Blyth<br />

(1999).<br />

Action: Design and implement a program f<strong>or</strong> monit<strong>or</strong>ing the fl<strong>or</strong>a <strong>of</strong> the heath<br />

community<br />

Responsibility: MTFRT<br />

Estimated cost: MTFRT to determine costs<br />

Completion date: Ongoing<br />

3.5 Continue to liaise with current owners, land managers and other interested groups<br />

Most <strong>of</strong> the occurrences are privately owned: The involvement <strong>of</strong> land managers, landholders, local<br />

community groups and industry in the recovery <strong>of</strong> the community wherever possible and practical is<br />

theref<strong>or</strong>e essential to the recovery process.<br />

Action: Continue to liaise with current owners, land managers, and other interested<br />

groups<br />

Responsibility: CALM (WATSCU) via MTFRT<br />

Estimated cost: $500 per year<br />

Completion date: Ongoing<br />

3.6 Encourage and assist landowners to gain access to available incentives and<br />

mechanisms f<strong>or</strong> conserving the community<br />

Incentives f<strong>or</strong> protection include the Remnant Vegetation Protection Scheme, CALM and National<br />

Trust covenanting systems, Land f<strong>or</strong> Wildlife and other funding programs that are available to promote<br />

long term protection <strong>of</strong> the community.<br />

Action: Encourage and assist landowners to gain access to available incentives and<br />

mechanisms f<strong>or</strong> conserving the community<br />

Responsibility: MTFRT<br />

Estimated cost: $Nil<br />

Completion date: Ongoing<br />

3.7 Seek rate rebates f<strong>or</strong> ‘protected’ occurrences<br />

CALM will negotiate with the Shire <strong>of</strong> Mo<strong>or</strong>a and the WA Municipal Association to provide partial <strong>or</strong><br />

total rate rebates f<strong>or</strong> occurrences covered <strong>by</strong> conservation agreements (ie. covenants). A provisional<br />

period <strong>of</strong> supplementation to the Shire could be used as an inducement (Binning and Young 1997).<br />

Action: Seek rate rebates f<strong>or</strong> ‘protected’ occurrences<br />

Responsibility: CALM (WATSCU and Mo<strong>or</strong>a District)<br />

Estimated cost: Based on outcome <strong>of</strong> negotiations<br />

Completion date: Ongoing<br />

3.8 Fence all known occurrences<br />

Interim Recovery Plan No. 65<br />

Fence occurrences to ensure stock (and subsequent weed invasion) are excluded and vehicle access can<br />

be limited to management access only. F<strong>or</strong> those occurrences that are already fenced, seek funds to<br />

assist in maintenance.<br />

Action: Fence all known occurrences<br />

Responsibility: MTFRT<br />

Estimated cost: MTFRT to determine costs<br />

Completion date: Ongoing<br />

3.9 Design and implement weed control strategy<br />

As all occurrences are adjacent to cleared farmland and most are weed infested, a weed control strategy<br />

is required that takes into account the nature <strong>of</strong> the community and the need f<strong>or</strong> continuing<br />

maintenance. The weed control program should involve:<br />

1. Identifying and mapping the weed species<br />

2. The selection <strong>of</strong> the appropriate herbicide<br />

3. The control <strong>of</strong> invasive weeds <strong>by</strong> hand <strong>or</strong> spot spraying as soon as the weeds emerge.<br />

Action: Design and implement weed control strategy<br />

Responsibility: MTFRT<br />

Estimated cost: MTFRT to determine costs<br />

Completion date: Ongoing<br />

3.10 Implement replanting and rehabilitation where necessary<br />

Seek to replant and rehabilitate occurrences that have suffered disturbance – due to the weed control<br />

strategy (recovery action 3.9), fire <strong>or</strong> other such disturbance. The appropriate species can be identified<br />

from plot data f<strong>or</strong> each occurrence held in Griffin (1994) <strong>or</strong> from fl<strong>or</strong>a monit<strong>or</strong>ing (recovery action 3.4).<br />

These should then be propagated from stock from surrounding areas to preserve local provenance.<br />

Action: Implement replanting and rehabilitation where necessary<br />

Responsibility: MTFRT<br />

Estimated cost: MTFRT to determine costs<br />

Completion date: Ongoing<br />

3.11 Determine the fire ecology <strong>of</strong> the community<br />

Seek funds f<strong>or</strong> research into recovery <strong>of</strong> the community (and target species) from fire, and to determine<br />

the implications <strong>of</strong> findings f<strong>or</strong> management (eg. preservation <strong>of</strong> seed f<strong>or</strong> future re-introduction in case<br />

<strong>of</strong> fire, prescribed burning). This would also include developing a fire hist<strong>or</strong>y map <strong>of</strong> the occurrences,<br />

to be updated regularly.<br />

Action: Determine the fire ecology <strong>of</strong> the community<br />

Responsibility: MTFRT<br />

Estimated cost: MTFRT to determine costs<br />

Completion date: Ongoing<br />

3.12 Design and apply appropriate fire management plans<br />

Interim Recovery Plan No. 65<br />

A fire management plan should be developed with landowners and the relevant auth<strong>or</strong>ities. The plan<br />

should deal with minimising wildfires; the need f<strong>or</strong>, design, position and upgrade <strong>of</strong> firebreaks/firefighting<br />

access tracks; fire management (including the need f<strong>or</strong> and design <strong>of</strong> prescribed fire) and fire<br />

suppression. The plan should include an annual fire monit<strong>or</strong>ing and rep<strong>or</strong>ting schedule.<br />

Action: Design and apply appropriate fire management plans<br />

Responsibility: MTFRT<br />

Estimated cost: MTFRT to determine costs<br />

Completion date: Ongoing<br />

3.13 Liaise with surrounding landholders to ensure strategies f<strong>or</strong> fuel reduction on their<br />

lands do not impact on the community<br />

Liaise with owners and surrounding landholders to prevent burning at inappropriate times when fires<br />

are likely to spread to the community.<br />

Action: Liaise with surrounding landholders to ensure strategies f<strong>or</strong> fuel reduction on<br />

their lands do not impact on the community<br />

Responsibility: MTFRT in liaison with owners <strong>of</strong> land containing, <strong>or</strong> adjacent to, the community<br />

Cost: $Nil<br />

Completion date: Ongoing<br />

3.14 Seek to acquire occurrences on private land f<strong>or</strong> the conservation estate<br />

To secure the long-term recovery <strong>of</strong> this community, CALM will liaise with landholders, including<br />

Westrail, and seek to acquire appropriate occurrences if they are <strong>of</strong>fered f<strong>or</strong> sale. Such areas should then<br />

be declared Class A reserves f<strong>or</strong> the purpose <strong>of</strong> ‘Conservation <strong>of</strong> Fl<strong>or</strong>a and Fauna’ vested in the<br />

National Parks and Nature Conservation Auth<strong>or</strong>ity (NPNCA).<br />

Action: Seek to acquire occurrences on private land f<strong>or</strong> the conservation estate<br />

Responsibility: CALM (Land Acquisitions Section)<br />

Estimated cost: CALM to negotiate costs on a market/valuation basis<br />

Completion date: When available<br />
