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 A study people – Protected Area interface at Keibul Lamjao National Park, Manipur.(Wildlife Institute of India, Dehradun, 2014) Leima, Sanggai; Badola, Ruchi; Hussain, S.A.Keibul Lamjao National Park (KLNP) is the only natural home of the remnant population of endangered brow antlered deer or Sangai whose habitat is the phumdi- a unique part of the habitat of KLNP. It is a floating mass of entangled vegetation formed by the accumulation of organic debris and biomass with soil particles. It covers approximately two thirds of the area of the park and the thickness varies from a few centimeters to about two meters. However, due to illegal exploitation of resources from the park in the form of vegetable and fuelwood collection, the park is facing consistent anthropogenic pressures which are posing a threat to the habitat of Sangai. A need arises to understand local people’s dependence on the park as well as their perceptions and attitudes in order to devise management strategies to solve parkpeople conflicts. Thus, the main objectives of the present study were to (a) examine the socioeconomic and demographic conditions of the villagers around KLNP, (b) quantify the resources extracted from the park and its contribution to the livelihoods of the local people, (c) assess the impacts of anthropogenic activities on the wildlife habitat, (d) examine the conservation awareness and attitudes of people towards the park and alternative livelihood options and (e) to assess the economic value of the park in terms of recreation for the conservation of Sangai and KLNP.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 Ecological impacts of anthropogenic pressures on high altitude forests along Bhagirathi catchment.(Wildlife Institute of India, Dehradun, 2001) Awasthi, Anjali; Rajvanshi, Asha; Rawat, G.S.The forests of Bhagirathi catchment in Garhwal Himalaya (Uttaranchal) have faced anthropogenic pressures since pre-British period. However, human induced disturbances increased during British period when the commercial exploitation of these forests started. It was during this period that the cultivation of potato and apple orchards were introduced in the region. These initial phases of transformation paved way for more recent changes in land-use practices and degradation of high altitude forests. The modern phase of degradation started with the construction of road to Gangotri in the middle of 20th century and opening up of Garhwal for tourism which led to development of infrastructural facilities and influx of mass tourism in the inner valleys. These added pressures on the remaining forests of Bhagirathi valley. 2. Ecological impacts of anthropogenic pressures and patterns and processes of forest degradation have not been quantified in this valley so far. Therefore, the present study was carried out in a part of the Bhagirathi catchment (78015' to 790 E long. & 30030' to 31 008' N lat.). The objectives of the study were: to assess the resource use patterns of villagers, transhumant communities and tourists, to assess the impacts of anthropogenic activities on forests and wildlife and to detect changes inland-cover classes over time and space. The study area is visited seasonally by various transhumant communities who also depend on the surrounding forests for a period of about six months. Four forms of transhumance viz., Nomadism, Semi-nomadism, Transmigration and Nuclear Transhumance were identified in the Bhagirathi valley. -Nomadism is followed by Gujjars, semi-nomadism by Gaddis, transmigration by Jadhs and Garhwalis and Nuclear transhumance by resident Garhwalis. Nomadic people have temporary hutsat both summer and winter settlements whereas transmigrants have permanent houses. Seminomadic and nuclear transhumants have one temporary and one permanent settlement. The impact of 'resource extraction by locals, transhumant communities and tourists on the forests was assessed. It was found that forests located close to villages (zone-I) and temporary settlements (zone-III) were under high lopping/cutting pressure.Item Livestock grazing and conservation of biodiversity in the high altitude ecosystem - An integrated landscape management approach.(Wildlife Institute of India, Dehradun, 2000) Mehra, Badrish S.; Mathur, P.K.The present study therefore, aimed to assess various issues of livestock grazing on a regional landscape basis and to suggest a long term strategy for integrating sustainable grazing compatible to biodiversity objectives. The study formed a part of the major 5-year Forestry Research, Education and Extension Project (FREEP) implemented in the GHNPCA and its surrounds. The present study was undertaken in the Great Himalayan National Park Conservation Area (GHNPCA), Himachal Pradesh comprising three PAs viz., the Great Himalayan National Park (GHNP), Tirthan Wildlife Sanctuary, Sainj Wildlife Sanctuary and an Ecodevelopment Zone (EZ) encompassing an area of 1,171 sq km. The local inhabitants in the GHNPCA have reared livestock since time immemorial and have followed transhumant pastrolism. According to the common belief amongst the local people, conservationists and wildlife managers, the livestock population and herd or flock size have increased substantially overtime; grazing practices are harmful to wildlife and also leading to large scale degradation; and unregulated grazing in forests and alpine pastures is not compatible with the long term conservation objectives. The study revealed that the age old practice of seasonal transhumant pastrolism and their life style largely remained unaffected despite several changes brought in during the different ruling regimes, new technologies and overall development since the Pre-colonial period to till date. The caste system has influenced the social structure, work distribution and resource use. The landscape had a total pressure of an estimated 33,000 to 38,000 livestock including resident of GHNPCA as well as migratory beyond the Conservation Area.Item An assessment of eco-development initiatives in Periyar Tiger Reserve.(Wildlife Institute of India, 2007) Bhardwaj, Anil; Badola, RuchiThe present study was undertaken with the objectives of examining the kind of input provided to local communities (Ecodevelopment committees) through ecodevelopment program. To examine the impact of ecodevelopment program and to critically examine the factors responsible for the success and failure of ecodevelopment initiative with respect to Periyar tiger reserve and suggest measures for effective implementation of the future program. The study was carried out in and around Periyar tiger reserve, KeralaItem Study of pressure and dependency of local people on the natural resources of Mudumalai Wildlife Sanctuary with a veiew to devising compatible management strategies.(Wildlife Institute of India, Dehradun, 1998) Silori, C.S.; Mishra, B.K.Mudumalai Wildlife Sanctuary (WLS) (11° 32’-11° 42’ N and 76° 2T-760 45’ E) and the adjoining forests of Bandipur National Park (NP), Nagarhole NP Wynaad WLS and Sigur Reserve Forest (RF) form the largest contiguous elephant tract in the peninsular India. Location of Masinagudi village right in the middle of the link forest divide it to still narrower corridors (north and south corridors). A large chunk of the inhabitants of Masinagudi and its hamlets are landless labourers who came to this area in the recent past from the adjoining areas to work in a hydro-electric project. Most of the villagers in these villages maintain large herds of cattle in the surrounding forests for selling cow dung manure to the nearby tea and coffee estates. Many of them cut firewood from these forests to sell in the local market for making a living. The corridor forests between Mudumalai WLS and Sigur RF is thus subjected to heavy biotic pressure from the local people and their grazing cattle. Objectives :i) to investigate the socio-economic and cultural dimensions of sustenance problem of the local people, (ii) to quantify and analyze the pressure of local people and their cattle on the biomass resources of the corridor forest, and (iii) to design viable alternatives for people for mitigating their sustenance problem as well as reducing pressure upon the resource of the corridor forest and the surrounding elephant habitat.Item Ecology and Management of Lion and ungulate habitats in Gir.(Wildlife Institute of India, Dehradun, 1995) Sharma, Diwakar; Johnsingh, A.J.T.The Gir is the only refuge of the Asiatic lion (Panthera leo persica) in its range. This implies that long term conservation of the Asiatic lion will remain an overirding management objective. A study on the impacts of management practices on lion and ungulate habitat was conducted in Gir Protected Area (PA) from June 1991 to July 1994. The Gir . PA includes Gir Wildlife Sanctuary and National Park. It is situated between 200 55' to 21 0 20 'N and 700 25' to 71 0 15' E in the Southern part of Kathiawar peninsula in western Gujarat. Gir PA (hereafter Gir) is located about 60km South of Junagadh. The area which was .3,107 sq km iIi 1877 (Joshi 1976) has been presently reduced to 1,412 sq km, o~ which about 259 sq Ian is national nark. Gir is the last refuge of the wild Asiatic lions (Panthera leo persica) and long term conservation of the Asiatic lion is an overriding management objective of Gir. In order to improve habitat conditions in Gir, the park authorities, over the last 20-25 years have made some management interventions such as relocation of some maldharis (local graziers), reduction in livestock grazing (specially migrant livestock during the rainy season) and fire control. These measures have led to vegetational recovery and increase in wild ungulate and lion populations. Understanding this vegetational recovery was thought to be crucial to determine the extent of management intervention required. It also needed to be determined if the trend (especially in the western Gir) was toward a higher woody proportion both at shrub and tree levels, and whether this in long term would adversely affect ' the distribution and abundance of ungulates, and therefore, group hunting by the lions, their pride size and territoriality.Item Patterns of grazing, natural resources use by local community and their influence on wild ungulate (Ibex) habitats in Pin Valley National Park, Himachal Pradesh(Wildlife Institute of India, Dehradun, 2023) Targe, Kalzang; Adhikari, B.S.; Salvador, LyngdohThis study conducted for a comprehensive study in response to the imperative need for a deeper understanding of the impact of pastoralism on wildlife. The research is centered on the high-altitude rangelands of the Trans-Himalaya, which have a grazing history spanning millennia. The primary goal of this research is to analyse an agropastoral system and investigate its conflicts with wildlife, particularly in relation to the Himalayan ibex. The study is summarized into the following objectives. - To study the changing aspects of local and migratory herders in Pin Valley, - To study grazing patterns of livestock and wild ungulate (Ibex) in Pin Valley, and - To document the natural resource dependency of local agropastoral community in Pin Valley. The study on agropastoral practices and their influence on the wild ungulate ibex in the Trans-Himalaya area employed a variety of methodologies and data analysis techniques. The primary data collection took place between September, 2017 and December, 2019. The research conducted for social aspects in all thirteen villages but only villages dependent on National Park were considered for the analysis. Semi- structured interviews in thirteen villages ensuring representation from different strata, age groups, and genders. Additionally, two focused group discussions were organized in the villages that related with migratory herders with the aim of raising awareness about overstocking and over-grazing's impact on range land resources. To analyse changes in the traditional agropastoral system, data were collected for both the past (pre-2000, before green pea commercialization) and present (post-2017) periods. Informal discussions with local community members were held to understand trends in livestock numbers and composition. Data on agriculture practices were also recorded. The employed various methods to assess Ibex and livestock feeding habits, including direct and indirect observations, bite counts, and microhistological techniques. The findings of this thesis hold practical relevance for land use planning and conservation management strategies. The research findings contribute valuable insights into the interactions between agropastoral practices and wild ungulate Ibex in the Trans-Himalaya area, providing a foundation for guiding conservation and management implementations strategies in the regionItem Effect of village relocation on ground birds and small mammals in Sariska Tiger Reserve, Rajasthan, India(Wildlife Institute of India, Dehradun, 2017) Mondal, Rakesh; Goyal, S.P.; Nigam, Parag1) Conservation related resettlement has been practised in India from 1960' s. However, studies related to the effect of village relocation on wildlife are limited. 2) Exploitation of natural resources by resident communities causes direct negative impact on native fauna and flora. These activities may include extraction of natural resources (fodder and fuel) or competition for the available resources by existing livestock with native fauna. Alterations in the vegetation structure can result in alteration of the bird community in these areas. 3) Galliformes is one such taxon that has been documented to be affected by human disturbance and grazing. These species are good indicators of habitat quality as they are solely dependent on the ground layer for food and cover. 4) There are 29 villages inside the Sariska Tiger Reserve and a relocation effort initiated as early as 1966 provides an excellent opportunity to study its effect on wild fauna and flora. 5) The study was carried out in four sites, with two sites where villages had been relocated 50 years (Slopka) and 10 years back (Bhagani); one site where village had been partially relocated (Sukola) and one where the village still existed The primary objective was to understand the influence of village relocation on Ggalliformes, small mammals and small carnivores. Additionally, vegetation structure at each village was also studied to understand influence of village relocation on natural vegetation.
