    A study on the structure and composition of forests along an altitudinal gradient in upper Bhagirathi catchment, Garhwal Himalaya.
    (Wildlife Institute of India, Dehradun, 2001) Uniyal, Sanjay; Rawat, G.S.; Biswas, Sas
    The present study highlighted the role of anthropogenic factors in distribution of plant communities in addition to altitude, aspect and slope. Market oriented economy has influenced the ethnobotanical knowledge of the local people. Though human-induced pressures are increasing in the area, still the status of forests in Bhagirathi valley is satisfactory compared to neighbouring areas. Hence, proper conservation and scientific management of such rich and diverse forest in small watersheds should be taken up on a priority basis. Data were collected from primary and secondary sources. Field work (primary source) was carried out during July 1996 to July 1999. Stratified random sampling was done for quantification of various vegetation and site parameters. The study area lies between 780 18' to 780 57' E long and 300 30' to 31 0 08' N lat. It covers an area of ca 2050 sq.km. and has an altitudinal gradient of 279 to 6600 m. For the intensive work two representative watersheds viz., north facing Duggada watershed (DWS) and south facing Bhatwari watershed (BWS) were selected. Objectives of the study include: preparation of baseline vegetation maps of the area, assessment of forest structure and composition, quantification of available woody biomass, documentation of ethnobotanical knowledge of local people and assessing the conservation status of rare plants in the area.

    The ecology and conservation of ungulates in Great Himalayan National Park, Western Himalaya.
    (Wildlife Institute of India, Dehradun, 1999) Vinod, T.R.; Rawat, G.S.
    Ungulates form a major component of the mammalian fauna in the Himalaya. In total, 19 ungulate species belonging to four families viz., Moschidae, Cervidae, Bovidae and Equidae, inhabit the Himalaya, out of which eight species are reported from the state of Himachal Pradesh (HP). Apart from some surveys and short term ecological studies on a few ungulate species of Western Himalaya, there has been no detailed study on ungulates of HP except for Himalayan ibex (Capra ibex sibirica). The available literature highlights the difficulties of studying rare and/ or elusive ungulates in Himalayan condition. Long term study on the ecology of theses' species are needed for the conservation and monitoring. Present study on the ecology and conservation of ungulates namely goral (Nemorhaedus qoral), Himalayan musk deer (Moschus chrvsogaster), Himalayan tahr (Hemitragus jemlahicus), in Great Himalayan National Park, Kullu district, HP, was conducted from January 1996 to November 1998. An intensive study area of ca. 90 km2 was selected in the South-western region of. the Park, which represents various ecological zones of the Park. The objectives of the study were (i) to estimate the abundance and density of goral, Himalayan musk deer & Himalayan tahr in relation to human use, (ii) to determine the group size. composition & sex ratio of these animals. (iii) to study the habitat use pattern and (iv) to identify and discuss conservation issues. mitigation measures and to develop a long term' monitoring programme. In this study an attemp has been made to estimate the abundance and density of major ungulates viz, goral, Himalayan musk deer and Himalayan tahr

    Ecological studies on the grassland of Eravikulam National Park, Kerala.
    (Wildlife Institute of India, Dehradun, 1998) Karunakaran, P.V.; Rawat, G.S.
    An ecological study on the. montane grasslands of Eravikulam National Park (ENP), the Western Ghats, was conducted during 1992-1996, with the following objectives: (i). to prepare a complete floristic inventory of the grasslands of ENP, (ii). to identify the grassland communities, their structure, function and successional trends along the anthropogenic gradient, (iii). to determine the forage quantity in different ecological conditions and (iv). to study the effect of fire and tree plantations on the grasslands. 2. The ENP lies between 10° 5’ to 10°20’ N and 77° to 77°10’ E with an area of 97 km2 in the Southern Western Ghats. The study recommends the following research and management strategies for the long term conservation of Shola-Grassland ecosystems and endangered Nilgiri tahr: (a) inclusion of adjecent reserved forests with shola-graslands in the park, (b) boundary verification and better patrolling to check the illegal activities and fire hazards, (c) early burning in selected areas on experimental basis, (d) control of black wattle spreading, (e) ecodevelopment measures for the Lakkamkudi village, (f) better tourism management and (g) long term monitoring of exclosures and representative shola-grassland patches.

    Pastoral Practice and Herders Attitude Towards Wildlife in South Gobi Mongolia
    (Wildlife Institute of India, Dehradun, 2011) Mijiddorj, Tserennadmid; Rawat, G.S.; Badola, Ruchi
    This study deals with analysis of traditional and current pastoral practices in south Gobi areas of Mongolia with emphasis on herders' attitude towards wildlife. The study was conducted during December 2010 to May 2011. The major objectives of the study were to study: (i) Nomadic herders' pastoral practices and drives of changes. (ii) Influence of pastoral practices on human-wildlife conflict and (iii) nomadic herders' attitude towards wildlife. I used questionnaire surveys in two villages in Gurvantes soum to find out the past and current patters of herding, herders' attitudes and major drivers of changes. The villages were selected based on the fact that in one village (Tost), Snow Leopard Conservation initiatives are going along with livestock insurance and research programs, while in another village (Baysah) no conservation initiatives have been undertaken. However the range use patterns by the local herders and the level of conflict with wild carnivores is the same in both areas. A total of 144 individuals from different age, gender and educational background were interviewed, 74 in 8 aysah (nonconservation) area and 70 from Tost area where snow leopard conservation activities are taking place. The data were analyzed using SPSS Statistical Package for Social Sciences (SPSS) PC version 16.0 for . Generalized linear model GLM linear and negative binomial with log linear model. The study reveals that the pastoral practices among the herders in the study area is largely influenced by land tenure, mining disorder, school kids' admissions and development factors. Assessment of pastoral practice changes revealed that 84.7% herders had highly altered their seasonal movement pattern which can affect pasture degradation and regeneration of grass growth. Owing to changes in pastoral practices, the herders have become more prone to lose more livestock to carnivores. Using GLM models it is proven (Wald chi-square =4.551 df=11 P=O.033) that recent faulty pastoral practice change (.e.g, nuclear family, vulnerable for natural disaster and herding techniques) explains livestock losses due to the carnivores. It requires implementing livestock husbandry management in better ways. Gurvantes soum's two different villages offered ideal condition to compare carnivore conservation efficiency and way to forward to mitigate such human-wildlife conflict. Study indicated that in generally herders positive perception towards ungulates whereas carnivores Tost (conservation area) area herders' tolerance level was higher than those of baysah area (non-conservation area) (t=5.23, df=89.
