The standing dead biomass of a grassland community of Kaptipada forest range (21 0 51' N; 86 0 53'E) in Odisha was carried out following " short term harvest method " of Odum (1). The standing dead biomass values of the experimental site exhibited an increasing trend from July to December and then attend a peak in the month of January (78.64 g m-2). Thereafter, a decreasing trend in value was observed and showed a minimum of 3.44 g m-2 during June. Onwards, the value again showed increasing at the end of the sampling period. The mean standing dead biomass of the community was found to be 37.31 g m-2. The mean standing dead biomass value of the community, when compared to other grassland communities, present findings did not show similarity. This variation in standing dead biomass value might be due to the variation in topography, species composition, climatic conditions, soil characteristics and the biotic interference of the locality.

DYNAMICS OF ABOVE GROUND HERBACEOUS BIOMASS IN HIGH ALTITUDE RANGELANDS OF PAKISTAN2019 •
Periodic monitoring of above ground biomass is a vital component for effective management of rangelands health and productivity. Rangelands in Gilgit-Baltistan are dominant land-use forms, spanning over 25% (16450.5 km 2) of its total area, and contributing about 30-40% in the total household income. The present research is an attempt to document the field based above ground biomass assessment of selected rangelands in the Hindu-Kush, Karakorum and Himalayan (HKH) regions of Pakistan and to relate it with the current livestock numbers in order to assess the grazing pressure on these rangelands. Five sampling plots (1km 2) at 17 catchments of five watersheds, representing the three mountain ranges were randomly selected for the study. The mean elevation of sampling plots ranged from 2500 m to 4100 masl. Within each sampling plot 3 quadrats (1m 2) were chosen, located, at least, 250 m apart from each other. For each of the sampling plot plant species were identified, biomass was calculated, and evenness and diversity of species was determined. On average the wet as well as dry biomass, across all the grazing areas was 2279 kg/ha and 650 kg/ha, respectively, with highest in Khunjerab (2831 and 704 kg/ha) and lowest in Bathraite (1590 and 596 kg/ha). About 138 species belonging to 27 families were recorded from the study areas. The highest species richness was found in the Deosai Plains (11) followed by Bathraite (10). It was observed that the grazing areas nearest to the permanent settlement have highest non-palatable species, possibly due to extensive grazing. Grazing pressure in all pastures is increasing with maximum in Babosar and Bathraite, showing decline in productivity of the rangelands at these sites. Grazing management can improve pastures conditions as evident from high biomass in Khunjerab, attributed to grazing management under the National Park regime. This research will provide a baseline study for further research on rangeland management activities in the area and their sustainability.

A study was conducted in the valley of Chagharzaiin Bunair district lying in the north Trans- Himalayan moist zone occupying Malakand Division, North Western Frontier Province (NWFP), Pakistan to determine the nutritive value of locally available marginal,land grasses. The study area lies between 34.42 to 34.66, longitude, having a humid subtropical to temperate environment. The annual precipitation varies from 600 to 1000 mm, mainly during summer,and spring. Twelve marginal ,land grasses were ,identified and analyzed ,for dry matter (DM), organic matter (OM), ash, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemi-cellulose, and lignin contents. The mean percentage values for DM, OM, ash, CP, NDF, ADF, hemi-cellulose and lignin at early bloom stage were 30.1±1.08, 27.6±0.92, 8.1±0.33, 8.7±0.39, 52.3±0.25, 25.8±1.36, 26.6±1.75 and 3.7±0.17, respectively. The mean percentage values for DM, OM, ash, CP, NDF, ADF, hemi-cellulose and lignin at mature sta...

The effects of cutting and burning on grass quality and axis deer (Axis axis) use of grassland in lowland Nepal1997 •
ABSTRACTMan-made grasslands dominated by Imperata cylindrica (L.) Beauv. in forested areas of lowland Nepal are commonly cut and/or burned annually. Changes in grass forage quality following different treatments of cutting and burning and axis deer (Axis axis) response to such habitat manipulations were investigated. Samples of matured grass were collected in December 1990, February and April 1991 from three experimental sites: cut, burned, cut-and-burned. Four locations on cut-and-burned grassland were repeatedly sampled at 12-d intervals from January to April 1992. Numbers of axis deer were recorded during the dry season of 1991/1992 on grassland plots receiving the following treatments: cut, cut-and-burned, and uncut/unburned (controls). Based on grass quality differences between December and February and between December and April, cut-and-burned treatments gave the greater increase in forage quality. N was significantly higher on cut-and-burned plots than on cut plots both in F...
The live green biomass of a grassland community of Kaptipada forest range (21 0 51' N; 86 0 53'E) in Odisha was carried out following " short term harvest method " of Odum (1). The live green biomass values of the experimental site exhibited an increasing trend from July to August and then attend a peak in the month of September (1485.90 g m-2). Onwards, a gradual decrease in value was observed showing a minimum of 116.14 g m-2 during April. Thereafter, the value again showed an increasing trend till the end of the sampling period. The mean live green biomass of the community was found to be 760.41 g m-2. The mean live green biomass value of the community, when compared to other grassland communities, present findings did not show similarity. This variation in live green biomass value might be due to the variation in topography, species composition, climatic conditions, soil characteristics and the biotic interference of the locality.

We compared the community structure, nutritive quality, and aboveground biomass of grazing lawns (patches of shortgrass communities) to neighboring grasslands in the Terai of western Nepal. Grazing lawns differed from the adjacent grasslands in species composition and community structure. Species diversity and species richness were higher on grazing lawns (H = 1.60, S = 20.93) than the grasslands (H = 0.97, S = 8.97). Fencing that excluded grazers for 150 days made areas of grazing lawns indistinguishable from neighboring grasslands in terms of plant height and biomass. Growing shoots of forage from grazing lawns had higher digestibility, crude protein, and sodium than forage from the grasslands. Grazing lawns appear to be maintained by continuous grazing and are enriched by deposition of urine, dung, and by certain plant species not found in the the adjacent grasslands.Hamile nepalko paschimi terai chetrako grazing lawn (choto samudayik ghans bhayeko chetra) sanga cheuchauko ghanse maidan ko community structure, paustik matra ra aboveground biomass ko tulana garyou.

Cholistan desert is hot and an arid rangeland located in the southern Punjab, Pakistan. The wet season lasts from June to September, whereas dry season falls from October to January with seasonal and annual variation in rainfall and temperature. The monthly sampling over 2 year’s period was carried to determine the grass productivity from 20 sites during 2010-12. The average dry biomass production of grasses was 263.22 Kg/ha during the dry season, whereas the same was 370.22 kg/ha in wet season. The maximum carrying capacity (17.25 ha/AU/year) was observed in the wet season, while the same was the lowest (24.2 ha/AU/year) during the dry season. Based on the results, it is concluded that the Cholistan rangeland is degraded due to overgrazing resulting into reduction in biomass production especially during the dry season coupled with the removal of palatable species from the whole rangeland. There is need to manage proper stocking rate during the growing season along with the introduc...
