    An ecological study on the pheasants of Great Himalayan National Park, Western Himalaya.
    (Wildlife Institute of India, Dehradun, 2003) Ramesh, K.; Rawat, G.S.
    The primary focus of the study was to describe the ecological and spatial distribution of three sympatric pheasant species, namely, Himalayan monal (Lophophorus impejanus), koklass (Pucrasia macrolopha) and western tragopan (Tragopan melanocephalus) in the Great Himalayan National Park (GHNP; 31 0 33' - 31 0 57' N and 770 17' - 770 52' E) in Himachal Pradesh, India. The specific were to: (i) review and test the currently available count techniques and provide estimates of relative abundance; (ii) document group size characteristics; (iii) describe habitat preference and investigate species coexistence; and (iv) develop a spatial model to predict availability of the potential habitats and the probability of occurrence of the study species. The study design included three broad approaches, namely, 1) field sampling, to estimate relative abundance and other behavioral and ecological parameters, 2) associative approach, to establish a relationship between the ecological distribution of the study species and habitat characteristics, and 3) Geographical Information System (GIS) based predictive spatial modelling. An area of 16 km2 was selected within GHNP, based on reconnaissance survey and literature, to serve as an intensive study 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

    Diversity and distributional pattern of family Geometridae (Lepidoptera) in Great Himalayan National Park
    (Wildlife Institute of India, Dehradun, 2021) Mallick, Kaushik; Gupta, S.K.
    Lepidoptera is a large and diverse group of insect which includes moths (Heterocera) and butterflies (Rhopalocera). The current study aims to give a clear idea of the diversity and distribution pattern of Geometrid moths in the area which will act as a database for future works. It will also assess the environmental factors governing the distribution pattern of Geometrid moths across different vegetation and habitat type in the study area. Understanding the response of Summary moth fauna with respect to various disturbance factors will help in the implication of management plans to protect significant habitats. The Great Himalayan National Park (GHNP) Conservation Area, located in Kullu District of Himachal Pradesh, falls under the North- Western Himalayan Biotic Province- 2A, lies between 31°31’16” and 31°56’41” N and 77°20’ to 77°52’11” E, covering an area of 1171 km2 and showing an altitudinal variation of 1300 m to 6110 m. Among the total sampled moth assemblage of GHNP, majorly 91% species were found to be Oriental origin, while 83.5% species also had affinities to Palearctic region. In the context of Indian Biogeographic Zones and Provinces, only 21% and 26% species were distributed in two Trans-Himalayan Provinces, Ladakh Mountain (1A) and Tibetan Plateau (1B). Almost 80% species were shared with Western Himalaya (2B) as the landscape located close to that province viz., North-western Himalaya (2A), 72% with Central Himalaya (2C) and 45% species with Eastern Himalaya (2D). 45% species were shared with North-Eastern Hills & Valleys.

    Response of small carnivore community to landscape and climatic variability in the Great Himalayan National Park Conservation Area, the Western Himalaya
    (Wildlife Institute of India, Dehradun, 2022) Bandyopadhyay, Meghna; Ramesh, K
    This study will add knowledge about the elusive and lesser-known small carnivores in a gradient of disturbed and less disturbed habitats. Objectives The study focusses on the following objectives: 1) Occurrence and abundance estimation of small carnivores across space and time along the elevation gradient. 2) Assessment of community composition of small carnivores and association with other small carnivore species. 3) Evaluation of landscape sensitivity by representative small carnivore species. 4) Distribution modelling of indicator species to anthropogenic and climatic effects in the current context Study focusses on the arrangements of small carnivores along the elevation gradient in terms of site intensity usage and abundance of small carnivores. Marked (leopard cat) and unmarked (red fox) species were considered and statistical models were used to find the overall abundance and also across the elevation gradient in space and time. demonstrates the coexistence patterns of small carnivores (red fox and leopard cat) in three dimensions; space, time and diet. The niche dynamics was assessed and compared between low human disturbance and high human disturbance areas. Study reveals how the coexistence patterns of small carnivores change with differential human disturbances.
