Item Ranging and Habitat Utilization by the Himalayan Ibex (Capra ibex sibirica) in Pin Valley National Park.(Wildlife Institute of India, Dehradun, 1997) Bhatnagar, Yashveer; Rawat, G.S.The Himalayan ibex is an important prey species of the endangered apex predator of the alpine region, the snow leopard (Schaller 1977). There is an imminent threat to the trans-Himalayan areas in India due to increasing human activities. In this context the study is conducted to study ibex in a relatively safe population to learn about its habitat requirements and ranging behaviour. The study area is part of the Pin Valley National Park (PVNP; 31o 6' 40'' to 32o 2' 20'' N latitude and 77o 41' 21" to 78o 6' 19" E longitude), located in the South-East of the Lahul and Spiti district of Himachal PradeshItem Ungulates mediated effects on Vegetation Structure and Biomass in Panna Tiger Reserve, Central India(Wildlife Institute of India, Dehradun, 2023) Gupta, Deepti; Ramesh, K.; Rawat, G.S.Ungulates play an important role in shaping the plant community structure, species richness and distribution through herbivory, seed dispersal, trampling and adding nutrient to the soil.They also act as important component of food chain, and hence their abundance and distribution are directly related to the large carnivore survival. Distribution of ungulates is strongly influenced by plant phenology, spatial heterogeneity of the forage plants and seasonal rhythm. Ungulates having different body sizes, habitat preferences, and anti-predator strategies might show a range of responses to the vegetation structure and composition (tree density, basal area and species richness), habitat parameters (terrain complexity, water availability and slope) and anthropogenic pressure (cattle abundance and human proximity). Ungulates in tropical dry deciduous forests have been majorly studied as primary prey to large carnivores. Panna Tiger Reserve (PTR), situated in the Vindhyan mountain ranges in Madhya Pradesh, central India, between 24°27¢N to 24°46¢N latitude and 79°45′E to 80°09′E longitude. PTR is uniquely characterized by its 'terraced topography' and presents two tabletop mountains and a valley formed by the Ken River. For this study, I chose four ungulates species having different habitat preferences, dietary requirements and body size viz., sambar (primarily a browser), chital (primarily a grazer), Nilgai (mixed feeder) and wild pig (omnivorous). Research objectives are as follows:1. To determine the vegetation structure and composition and quantify the above-ground biomass 2. To estimate the density of ungulates across space and seasons. 3. To model the ungulates-habitat relationships and related functional responses.Item Influence of pastoral practices on wild ungulates in Upper Gori Valley, Western Himalaya.(Wildlife Institute of India, Dehradun, 2020) Bhattacharya, Ankita; Rawat, G.S.; Habib, BilalThe alpine meadows of western Himalaya have been used for livestock grazing by a large number of agro-pastoral communities for several centuries (Tucker 1986). Five distinct pastoral practices are prevalent across the alpine landscape in the western Himalaya: nomadic, semi nomadic, nuclear transhumance, trans-migratory and sedentary (resident). Trans-migration (seasonal altitudinal movement by the entire family along with the livestock) is practiced mainly by the Bhotiya communities in various parts of Uttarakhand, such as Byans, Darma, Johar and the upper basins of Alaknanda and BhagirathiItem A study on habitat use and food habits of swamp deer (Cervus duvauceli duvauceli) in Jhilmil Tal, Haridwar Forest Division, Uttaranchal(Wildlife Institute of India, Dehradun, 2009) Tiwari, Rachna; Rawat, G.S.Habitat use and food habits of the swamp deer (Cervus duvauceli duvauceli) were studied in and around Jhilmil Jheel Conservation Reserve (JJCR), Uttarakhand, during June 2006 and June 2008. This population of swamp deer was recently rediscovered in the state and warranted an ecological study and conservation initiative because the habitat around this study area is heavily fragmented due to expansion of agriculture, habitation and various other land use practices. Therefore, this study was initiated. The major objectives were: i. ii. iii. To study seasonal variation in habitat use pattern and food habits, Activity pattern, Population structure and habitat condition, and iv. Identify threats and suggest conservation measures. Habitat evaluation of various potential (but fragmented) habitat blocks in Jhilmil Jheel Conservation Reserve area and surrounding Banganga wetland revealed that they bear a close resemblance with the prime swamp deer habitat both in terms of structure and composition of key habitat variables.Item 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
