Item Ecology of alpine arid pastures with special reference to livestock grazing in upper Dhauli valley, Nanda Devi Biosphere Reserve, Western Himalaya.(2018) Mitra, Monideepa; Adhikari, B.S.; Rawat, G.S.Pastoral practices have been in existence in the alpine region of the Himalaya since millennia.The region is characterized by the presence of diverse pastoral practices such as sedentary, nuclear trans-humane, semi-nomadic, and nomadic pastoralism. These practices have strongly influenced the vegetation and ecology of the alpine rangelands, including local biodiversity. The region is broadly divisible into two distinct eco-climatic zones, viz., a moistal pine zone of Greater Himalaya and cold arid zone of Trans-Himalaya. These zones differ considerably in terms of physiognomy, species composition, history of livestock grazing and their ability to withstand grazing pressure. The objectives of the study were (i) To study the patterns of livestock grazing in the study area, (ii) To assess resource use by livestock, (iii) To assess the pasture quality (floristic) and quantity (biomass) in the study area, and (iv) to assess overlap in resource use between wild ungulates and livestock. The study was conducted in Upper Dhauli valley, situated in the cold arid region of Nanda Devi Biosphere Reserve (hereafter NDBR; 30º 08’-31º 02’N, 79º 12’- 80º 19’E) in Uttarakhand. The study was conducted in 2012 and 2014Item Ecology and management of savanna vegetation in Sariska Tiger Reserve, Rajasthan.(Wildlife Institute of India, Dehradun, 2015) Bhatt, Priyanka; Rawat, G.S.; Sankar, K.This study is aimed to document the role of various abiotic and biotic factors playing a vital role in the coexistence of trees and grasses. Attempts have been made to bridge the research gaps related to the structure and composition of forest vegetation, phenology diversity and regeneration patterns along the landscape. Hence, present study was initiated with a view to collect baseline data that would be helpful in monitoring the forest changes in future. It provides information about the savanna vegetation and the dynamics and also deals with the vegetation composition, species diversity, richness and other phyto- sociological parameters, Vegeation structure, composition and factors affecting the savanna vegetation in Sariska Tiger Reserve. Objectives are : 1. To study the phenology of savanna species 2. To study the aut-ecology of dominant savanna grasses and tree species of Sariska with reference to biotic and abiotic factors 3. To study the impact of invasive species and management implications: case study of Adhatoda vasicaItem Systematics and ecology of Berberidaceae in Uttarakhand state.(Wildlife Institute of India, Dehradun, 2011) Tiwari, Umesh Kumar L.; Rawat, G.S.; Adhikari, B.S.Item Ecology and management of the alpine landscape in the Khangchendzonga National Park, Sikkim, Himalaya(Wildlife Institute of India, Dehradun, 2007) Tambe, Sandeep; Rawat, G.S.In Sikkim the villagers practice a mixed livelihood strategy earning their income from agriculture, horticulture and animal husbandry. Livestock such as yak, cow, sheep, horse, buffalo and goats are grazed in the forests and alpine meadows of the state. During the beginning of the 20th century the forests of the state were demarcated and the Khasmahal and Goucharan forests were specifically set aside to meet the fodder and firewood demands of the villagers. The The genesis of this study lies in this conflict, wherein it was realized that a sound understanding of the ecology of the alpine meadows and pastoralism was needed to ensure effective management of these unique and fragile environments. It is with this objective that the present research study titled “Ecology and Management of Alpine Landscape in the Khangchendzonga National Park, Sikkim Himalaya” was initiated in 2004 which would evolve a long term conservation plan for the alpine zone of KNP. The study spans over a large spatial scale covering all the major watersheds of KNP and aims to bridge the knowledge gaps related to structure and composition of the alpine vegetation, alpine landscape characterization, sustainability of pastoralism, conservation strategy and co-management experiments. The purpose of the study is to provide a scientific basis for the long term conservation and sustainable and equitable use of the resources of the alpine zone of KNP to promote sustainable development in the state. The significance of the study is based in its ability to contribute in the formulation of a conservation plan for the alpine zone of KNP and a rational pastoral policy for the Sikkim Himalaya.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
