Item Status, habitat use and factors affecting breeding waterbirds of Changthang Wildlife Sanctuary, Ladakh (India).(Wildlife Institute of India, Dehradun, 2020) Mahar, NeerajTourism has evolved as an alternative livelihood for the local people and has reduced their direct dependencies on natural resources and perhaps indirectly contributed towards nature conservation. However, unregulated tourism activities have led to degradation of natural systems and increased the ecological vulnerabilities of local communities. Often, tourism and other developmental activities related disturbances collide with the peak season for several biological processes and affect the ability of natural system to revive and restore itself. In case of waterbirds these disturbance affect the breeding success. Other than anthropogenic activities, domestic dogs, apparently the most abundant carnivores in the world, pose a major threat to local wildlife. Recent studies have determined waterbirds as an important part of their diet. The existing literature clearly suggested that there was a huge information gap regarding Trans-Himalayan wetlands and their avifaunal characteristics. Previous studies were either site specific or species-specific, and thus, landscape level base line data was either scanty or unavailable. The Trans-Himalayan wetlands of India are increasingly under anthropogenic stress which is affecting their ecological structure and functions, especially the breeding birds. Blacknecked crane (BNC) is one of the flagship species of these wetlands. With the above background, I decided to study and understand their ecology and major threats faced by waterbirds and wetlands of Changthang Wildlife Sanctuary (CWLS). The objectives for this work were to (1) assess the population status and habitat use by waterbirds, (2)evaluate the factors affecting the breeding waterbirds, and (3) assess change in the wetland area.Item Status and spatio-temporal ranging behavior of leopard (Panthera pardus) in Dachigam National Park, Srinagar, J&K.(Wildlife Institute of India, Dehradun, 2021) Noor, Athar; Habib, Bilal; Gopi, G.V.This study was initiated by Wildlife Institute of India, Dehradun with support funding from the Department of Science and Technology (DST), Government of India, in December 2010 to December 2013 to estimate leopard population and prey abundance, to study the leopard feeding habits and to determine the ranging behavior of leopards in Dachigam National Park. This thesis is an outcome of the main study and has three main objectives. The first objective being to determine the population status of leopards; second is to study the ranging behaviour and habitat use by leopards and lastly to model habitat suitability for leopards in Dachigam National Park. This study also provides basic information about co-occurrence of mammalian species in the community of the moist temperate forest of the Kashmir Himalaya, IndiaItem Status and Ecology of the Andaman Crake(SACON, 2009) Ezhilarasi, N.; Vijayan, LalithaAndaman Crake is a rare and endemic bird of Andaman Islands. There was no detailed information available on this species and was listed as data deficient till recently. Hence a study was undertaken during 2004-2007 to collect baseline data on the population, ecology and biology of the Andaman Crake. A variety of factors is responsible for Andaman Crake's habitat degradation and loss. In this chapter I briefly highlight key findings of this study, major threats to this species and suggestions for conservation and future research. While these threats and recommendations are given for the conservation of the Andaman Crake, they pertain to several other species ecologically dependent on the wet forests.Item Status and Ecology of the Nilgiri Pipit in the Western Ghats.(SACON, 2007) Vinod, Uma J.; Vijayan, LalithaStudy was undertaken on the Nilgiri Pipit with the following main objectives a) determine the status b) unravel the ecology c) identify the key factors affecting the survival of the Nilgiri Pipit and suggest management optionsItem Status and ecology of the Nilgiri Wood Pigeon in the Western Ghats(SACON, 2006) Soumasunderam, S.; Vijayan, LalithaConservation of the species requires a comprehensive picture on the status and distribution, ecological requirements for feeding, breeding and other activities. Ecological studies on most of the endemics have not yet been conducted and hence, such information is not available for any management programmes. Moreover, human impacts on the habitats of most species are also not understood. Hence, the present study was conducted on an endemic, endangered species of the Western Ghats which is considered as Globally Threatened, the Nilgiri Wood Pigeon Columba elphinstonii, addressing mainly its biological and ecological requirements.Item A study on ethno-flora with special reference to Traditional Health Care System (THCS) in western Ladakh, Jammu & Kashmir.(Wildlife Institute of India, Dehradun, 2013) Angmo, Kunzes; Adhikari, B.S.A study on ethno-flora with special reference to traditional health care systems (THCS) was conducted in Western Ladakh, Jammu & Kashmir (Indian Trans-Himalaya) during 2009-2013. The major objectives of the study were: i) to study and compare the traditional health-care system across major ethnic groups (Boto, Balti and Dards) in Suru, Wakha-chu and Lower Indus valleys, ii) to document the Traditional Knowledge System (TKS) across various ethnic groups, and iii) to assess the conservation status of ethno-medicinal plants in the study area. To meet the objectives of the study a detailed field investigation was undertaken in all the valleys. The field work involved questionnaire survey and group discussions in the three valleys to document traditional healthcare system (THCS), perception of people and allopathic doctors regarding THCS (objective 1); Interviews of local healers and different sections of the society to assess the status of traditional knowledge (objective 2); and Rapid survey of wild medicinal plants across various land forms, habitat and vegetation types so as to ascertain the distribution of ethno-flora across various landforms, and ethnoecology and conservation prioritization of Ethno-flora (objective 3). The study area is located above 2700m altitude and is characterized by unique geographical and socio-cultural attributes. Traditional medicine is one of the tangible heritage of the local people in Ladakh, which has been an indispensable source of both preventive and curative medicine.Item Study of leopard menace, food habits and habitat parameters in Mandi Distrcit, Himachal Pradesh.(Wildlife Institute of India, Dehradun, 2012) Kumar, Devender; Chauhan, N.P.S.This study deals status, distribution and relative abundance of leopard in relation to habitat characteristics of leopard. Estimation of status of leopard population and its distribution become more important in an area when a species is highly threatened due to continuous habitat degradation and loss of habitat due to the increasing human population. Many carnivore species are rare or elusive, and documenting their distribution is difficult. Habitat requirement is also one of the most important factors which influence the distribution and abundance of a species, therefore habitat evaluation is a vital step in the formulation of carnivore management in an area. Large carnivores need large areas of relatively wild habitat. The assessment of nature and extent of man leopard conflict in relation to land use pattern. Carnivores exert a profound influence on biological communities via predation and interspecific competition. Human-carnivore conflict is considered to be a major conservation and rural livelihood issue because many carnivore species have been heavily persecuted due to elevated conflict levels with communities. Present study documented about the enormity of the problem, problem areas and human casualties and livestock depredation with respect to places of occurrence, season, time and circumstances of attack. It would help plan mitigation of leopard problem, besides conservation and future scientific management of the species in Mandi district, Himachal PradeshItem Estimating the Status and Impact of Hunting on Tiger Prey in Bardia National Park, Nepal(Wildlife Institute of India, Dehradun, 2009) Malla, Sabita; Jhala, Y.V.; Qureshi, QamarA study was undertaken to understand the status of tiger prey species in relation to the hunting pressure in Bardia from November 2008 to April 2009. The prey densities were estimated using distance sampling
