    Distribution of major alien invasive plants and impact assessment of Ageratina adenophora (Spreng.) K & R. in Kailash Sacred Landscape, Uttarakhand
    (Wildlife Institute of India, Dehradun, 2022) Chaudhary, Alka; Adhikari, B.S.; Rawat, G.S.
    The study was conducted to assess the spread, distribution, impact of invasion in Indian part of Kailash Sacred Landscape (KSL) characterized by interspersion of human habitations, extensive forest managed by the State Forest Department and local community institutions (Van Panchayat). The objectives of the study were (i) To model spatial distribution of selected plant invasive species using distribution modeling technique. (2) To assess the impacts of IAPs on native flora and relationship with habitat parameters (3) To analyze people's perception towards the spread of IAPs in KSL India landscape (4) Experimental trials on Eco restoration of habitats and prediction of future spread for better management

    Distribution of breeding Phylloscopus and Seicercus warblers in the Himalayas: Role of ecomorphology and competition.
    (Wildlife Institute of India, Dehradun, 2012) Ghosh, Mousumi; Rawat, G.S.; Price, Trevor
    Present study is carried out for the overarching goal of understanding the ecological and historical determinants of geographic and altitudinal distribution of sixteen breeding Phylloscopus and Seicercus species in the Himalayas. The broad research objectives were as follows: 1. Assess the availability of arthropod resources across the eastern and western Himalaya along the elevational gradients. 2. Identify the climatic correlates of the breeding distribution of Phylloscopidae. 3. Examine the geographic variation in foraging ecology of Phylloscopidae across the Himalayan bioclimatic gradient.

    A study on the traditional knowledge and population status of ethno-medicinal plants in Uttarkashi district, Western Himalaya.
    (Wildlife Institute of India, Dehradun, 2015) Raut, Ninad B.; Rawat, G.S.
    This study is design to identify the current status, Population status, Distribution of Ethnomedicinal plants (EMPs) for curative purpose. The aim of this study is to know the importance of these EMPs in order to prioritize them for conservation and suggest strategies for conservation and management of high value EMPs as well as mechanism for formalizing protection of Traditional Knowledge. Uttarkashi one of the largest and culturally diverse district of uttarakhand for this study

    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
