    Status, habitat use and factors affecting breeding waterbirds of Changthang Wildlife Sanctuary, Ladakh (India).
    (Wildlife Institute of India, Dehradun, 2020) Mahar, Neeraj
    Tourism 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.

    Assessment of the existing National Highway – 7 and its proposed widening on habitat use and movement of wild animals in Pench Tiger Reserve, Madhya Pradesh.
    (wildlife Institute of India, Dehradun, 2019) Pragatheesh, A.; Rajvanshi, Asha; Mathur, V. B.
    The construction of roads and railways change the natural landscape along the entire length of the road, or railway line, apart from fragmenting the landscape. Compared to national highways, narrow country roads have more intense network ad its penetration into the wild habitat is deeper and the adverse effect is therefore manifold as compared to a single national highway. mobility of people and transportation of goods is an integral component of globalization and economic opportunity, road infrastructure that enhances connectivity among people also results in increased habitat fragmentation which is recognized as the largest single threat to biological diversity

    Human-tiger conflict, ranging pattern and habitat use by tiger in Sundarban Tiger Reserve, India
    (Wildlife Institute of India, Dehradun, 2015) Naha, Dipanjan; Sankar, K.; Qureshi, Qamar
    The Sundarban tiger inhabits a unique mangrove habitat type, isolated from neighboring tiger populations by hundreds of kilometers of agricultural and urban land. The main objectives of the present study were to (a) understand ranging pattern and habitat use of tiger (b) to quantify livestock losses by tiger predation and identify spatio-temporal patterns in conflict in and around the Tiger Reserve (c) to document and quantify the geographic distribution of tiger-human incidents and (d) to evaluate the perception and level of tolerance of people living in the vicinity of Tiger Reserve. This study showed that tiger home range range sizes are much larger than reported from Bangladesh Sundarban. The Sundarban Tiger Population is of global importance for the conservation of the species due to the size of the contiguous nature of the habitat and the unique adaptations of the tigers that inhabit these mangrove forests. In spite of only four tigers that could be radio-collared and monitored this study enhances our understanding aspects of tiger ecology in this unique landscape. Sundarban tigers are primarily diurnal, prefer certain habitat types and are reluctant to cross wide expanse of water. This information can be used to minimize human-tiger conflict which is a major impediment to tiger conservation in this region.

    Habitat use, ranging patterns and food habits of striped hyaena (Hyaena hyaena) in Kutch, Gujarat
    (Wildlife Institute of India, Dehradun, 2013) Bopanna, I.P.; Jhala, Y.V.
    Among the diverse carnivores found in Kutch, the striped hyaena is the one of the largest and the region is also a stronghold for the species. This study was developed for a better understanding of the ecology and behaviour of the species. It aims at providing a better understanding of density, food availability and sociability in hyaenas, at the interface of human land uses. The study was carried out mostly in Abdasa and parts of Lakhpat, Nakhatrana and Mandvi talukas in Kutch district of Gujarat state, for five years from January 2006 to January 2011. During the course of the study, the sudden influx of industrialization in the region changed the dynamics drastically, undermining traditional way of life and value system. This change in dynamics resulted in rapid change in land use patterns and illegal encroachment of prime wildlife areas, directly affecting the wildlife in the region. This study will directly contribute for the conservation of the species in the region and elsewhere and also determined the food habits and foraging patterns of the species in the region and its dependence on anthropogenic food sources.

    A study on habitat use and food habits of swamp deer (Cervus duvauceli duvauceli) in Jhilmil Tal, Haridwar Forest Division, Uttaranchal
    (Wildlife Institute of India, Dehradun, 2009) Tiwari, Rachna; Rawat, G.S.
    Habitat use and food habits of the swamp deer (Cervus duvauceli duvauceli) were studied in and around Jhilmil Jheel Conservation Reserve (JJCR), Uttarakhand, during June 2006 and June 2008. This population of swamp deer was recently rediscovered in the state and warranted an ecological study and conservation initiative because the habitat around this study area is heavily fragmented due to expansion of agriculture, habitation and various other land use practices. Therefore, this study was initiated. The major objectives were: i. ii. iii. To study seasonal variation in habitat use pattern and food habits, Activity pattern, Population structure and habitat condition, and iv. Identify threats and suggest conservation measures. Habitat evaluation of various potential (but fragmented) habitat blocks in Jhilmil Jheel Conservation Reserve area and surrounding Banganga wetland revealed that they bear a close resemblance with the prime swamp deer habitat both in terms of structure and composition of key habitat variables.

    Impact of land use changes on the habitat, bahaviour and breeding biology of Indian Sarus Crane (Grus antigone antigone) in the semi-arid tract of Rajasthan, India.
    (Wildlife Institute of India, Dehradun, 2007) Kaur, Jatinder; Choudhury, B.C.
    The Sarus Crane has been recorded all over the northern India and central region of the Indian sub-continent historically. However, this once abundant tallest flying bird species has now become threatened. The present study was undertaken during the year 2000-2002 to i) to determine the habitat use, breeding biology and behavioural ecology of the Sarus Crane in the semi-arid tract of Kota, and Bharatpur in Rajasthan, and ii) to determine the changes in land-use and its impact on Sarus Crane in the semi-arid landscape and to suggest the conservation strategies for the long-term survival of Sarus Crane. The study was conducted in the semi arid tract of Kota, and Bharatpur districts of Rajasthan. District Kota, the first intensive site falls under arid Zone V (the humid south-eastern humid plain zone,) where the development of canal irrigation has made this area rich in agricultural production. The population of Sarus Crane in Kota are dependent mainly on the canal system induced and other natural wetlands. Data on distribution and habitat utilization of Sarus Crane in Kota and in Keoladeo Ghana National Park were carried out

    Habitat use by sympatric small carnivore in Sariska Tiger Reserve, Rajasthan, India.
    (Wildlife Institute of India, Dehradun, 1998) Mukherjee, Shomita; Johnsingh, A.J.T.
    The present study on three sympatric carnivores, two felids: jungle cat (Felis chaus), and caracal (Caracal caracal) and one canid, the golden jackal (Canis aureus) aimed at studying their spatio - temporal use of food resources. The hypothesis are as follows : 1) Jungle cat is relatively more eclectic in the kind of habitat it inhabits than the jackal. 2) The felids are mostly nocturnal whereas the jackal is both diurnal and nocturnal ( cathemeral). 3) Diet of the three carnivores differs between seasons. 4) Small mammals «1 kg. body weight) form the major diet of the felids and are taken in proportion to their abundance. 5) Jungle cat and caracal are dietary specialists relative to the jackal. The study was conducted in Sariska Tiger Reserve (STR) which is located between 74° 17' to 76° 34'N and 25° 5' to 27° 33' E. STR encompassing an area of BOO km2 has three core areas of which core 1, with an area of 273.B km2 forms. the proposed National Park. This area functioned as the study site and the intensive study area was approximately 30 km2.
