An assessment of human-wildlife interactions in the Indus valley, Ladakh, Trans-Himalayas
(Wildlife Institute of India, Dehradun, 2012) Chandola, Shivani; Mathur, V.B.
The Hemis National Park, in the “Ladakh mountains” Zone 1A, presents such a case of human-wildlife interaction, where the Snow leopard (Panthera uncia) and the Tibetan wolf (Canis lupus chanko) are known to be the major cause of livestock losses to the agro-pastoral communities of this region. On the other hand, the livestock grazing and tourist influx have been cited as challenge for habitat and wildlife conservation. The present study was designed to improve upon the existing knowledge on the human-wildlife interactions in Ladakh. The major objectives of the study were to (i) study the pattern of resource use and its contribution to livelihood of local communities in Trans-Himalayan landscape; (ii) evaluate xi the pattern of conflicts arising from resource use practices by the local communities and its impact on wildlife values; (iii) examine the existing education systems and religio-cultural teachings in their ability to address the conservation issues of the region, and (iv) to examine the existing policy instruments and suggest improvement to minimize such conflicts. The assessment of natural resource dependency and sources of livelihood for the local community residing inside the HNP was carried out during 2005-2006 using data generated through questionnaire surveys, personal observations and secondary sources.
Application of Geographic Information System(GIS) and Remote Sensing in assessing habitat, resource availability and its management in Tadoba-Andhari Tiger Reserve.
(Wildlife Institute of India, Dehradun, 1999) Dubey, Yogesh; Mathur, V.B.
The present study attempts to determine the distribution and abundance pattern of ungulate species in Tadoba Andhari Tiger Reserve and to assist in the development of a computerised wildlife database on spatial as well as non spatial attributes, which could be used for conservation monitoring and evaluation as well as to help in resource management planning, With the increasing pressure on forests it has become important to focus the research effort which could eventually lead to a better management of our PAs.
Biodiversity conservation in Indian Sundarban in the context of anthropogenic pressures and strategies for impact mitigation
(Wildlife Institute of India, Dehradun, 2012) Vyas, Pradeep; Mathur, V.B.
The present study revealed that human-crocodile conflict is a low key affair whereas the information on human-shark conflict is almost non-existent. The data on human crocodile conflict from 1999 to 2009 revealed that a total of 29 persons were attacked by crocodiles, in which 12 people were killed and 13 were seriously injured. A total of 13 crocodile straying incidences were recorded during this period. The analysis of result of human-crocodile conflict reveals that it is restricted to the areas where tiger prawn (Penaeus monodon) seed collection is carried out. The tiger prawn seeds are collected mainly by women and children, who wade through water and drag fine net and in the process often become victims of crocodile attacks.

The study has covered the physical, floral and faunal aspects of Tiger Reserve.
Diversity and rarity in avifaunal assemblages in the western Himalaya: A study of patterns and mechanisms.
(Wildlife Institute of India, 2006) Raza, Rashid H.; Mathur, V.B.; Gaston, Kevin J.
This study focuses on patterns of diversity and rarity in the avifaunalassemblages of the Western Himalaya. It attempts to find patterns at a regional scale using a secondary database and through field studies at landscape scales at two intensive study sites, Kedarnath area and Goriganga valley in Uttaranchal. The study adopts a macroecological approach in arriving at statistical generalizations emerging from the analyses of distribution and abundance patterns of birds along the altitudinal gradient. The study identifies key patterns of composition, species abundances and species diversity seen in the Western Himalayas and attempts to understand some of the mechanisms associated with these patterns.
Geospatial modelling of ungulate-habitat relationship in Tadoba-Andhari Tiger Reserve
(2008) Paliwal, Ambika; Mathur, V.B.
The present study is an amalgamation of ecological theory, scientific technology and modern statistical modeling. It provides a sound basis for effective management of Tadoba Andhari Tiger Reserve TATR including preparation of science based management plans. the study aims to map landuse/landcover patterns and to assess spatial structure and configuration of landscape; structure and composition of vegetation types in landscape; spatial and ecological distribution of ungulate species in response to seasons and management status and habitat suitability and site occupancy using spatially explicit ungulate-habitat model. The study was carried out in Tadoba-Andhari Tiger Reserve (TATR). It lies in civil district of Chandrapur, eastern edge of Maharashtra. Field work was carried out between February 2005 and January 2007.
Habitat suitability evaluation for leopard (Panthera pardus) using remote sensing and GIS in and around Chitwan National Park, Nepal
(wildlife Institute of India, 2011) Thapa, Tej Bahadur; Mathur, V.B.; Goyal, S.P.
The leopard Panthera pardus is one of the large felid of Asia and Africa that is threatened by habitat loss and direct conflicts with humans. Owing to low population densities and cryptic habits leopard has remained little studied. This study evaluated landscape characteristics; determined distribution and relative abundance of leopards, analyzed diets of leopards and assess the extent, nature of human leopard conflicts and examined habitat use and preference in and around the Chitwan National Park and Buffer Zone (CNPBZ), Nepal. Methodologies used to accomplish these objectives included remote sensing, geographic information system (GIS), ecological field work (line transect sampling for prey, camera trapping for leopard and scat collection), social surveys and lab work for diet determination using micro histological technique. Abundance and density information forms the baseline for conservation planning. Camera-trap surveys were carried out during winter 2008/09 and 2010. This study provided much needed baseline information on habitat characteristics of CNPBZ, abundance of leopard and prey population, feeding ecology and prey selection by leopard, leopard- human conflicts and habitat use of leopards.
Habitat Utilization by Hog Deer (Axis Porcinus) in Relation to other Sympatric Species at Jaldapara Wildlife Sanctuary
(Wildlife Institute of India, Dehradun, 1999) Biswas, Tanushree; Mathur, V.B.; Sawarkar, V.B.
This study on habitat utilization by hog deer (Axis porcinus) in relation to other sympatric species (chital & rhino) was carried out from December 1998 to April 1999 in Jaldapara Wildlife Sanctuary, West Bengal, The spatial and seasonal differences in habitat utilization of grasslands by hog deer, chital and rhino were investigated, The study was restricted to various types of grassland s existing within the sanctuary which were broadly stratified into five major types: Pure grassland (natural ), pure grassland (plantation), Savanna grassland (natural) and Savanna grassland ( plantation) and riverine grassland, Different habitat were traversed on riding elephants on selected paths to collect data on animal abundance/hr based on sightings in different habitat types, A total of nine transects were laid in different habitats to quantify availability of habitat parameters and their selection. Dung abundance was quantified using belt transects, at each 100m interval on the transects, The availability and utilization of habitats based on direct and Indirect methods were examined using Neu et al (1974), The results showed that hog deer selected areas with extensive grass cover with structural mosaics of cover and mostly early phenophase as opposed to habitats with low cover values, High abundance of hog deer were found in areas with higher proportion of Imperata cylindrica, Fire or burning of grasslands in combination with rain seemed to influence the overall selection of habitat by hog deer, Cutting of thatch by local people also influenced the habitat use by hog deer, Area preferred by hog deer were found to have high cattle dung density thus showing a very high pressure on areas preferred by hog deer, Interaction with chital seemed to be very low as the areas preferred by hogdeer are avoided by chital, Rhino also showed a similar trend with preference for plantation grassland areas and avoidance for natural grassland, Apart from the effect of these sympatric species directly, habitat use by hog deer seemed to have been influenced by the management steps taken to provide protection to Rhino, Plantation areas raised for the management of rhino were avoided by hog deer.
Ranging, Activity Patterns and Habitat Use of Blackbuck and Nilgai in Velavadar National Park, Gujarat, India
(Wildlife Institute of India, Dehradun, 2001) Sahabandhu, H. Dhanushki R.; Chellam, Ravi; Mathur, V.B.
I studied the activity patterns, ranging and habitat use of blackbuck (Antelope cervicapra rajputanae) and nilgai (Boselaphus tragocamelus) in Velavadar National Park from November 2000 to April 2001. Scan sampling was used to record blackbuck and nilgai activity patterns. Herds were also followed from sunrise to sunset to study the diurnal movements. Satellite imagery was used for vegetation mapping. Habitat availability and usage of both species were examined by plotting the grazing circuit on the satellite imagery. Activity patterns were found to differ amongst the various social groups, habitats and seasons. Temporal variations in foraging time and resting time were found in all the groups studied. Blackbuck had three foraging peaks and two resting peaks as compared to nilgai, which had two, and one peaks respectively. Diurnal distances were not found to differ in any of the different blackbuck or nilgai groups or between the two species. Differences between blackbuck herds in different seasons and habitats were attributed to the nutritional levels and the spatial dispersion of vegetation. Foraging behaviour decreased in summer supporting results of previous studies that blackbuck reduced foraging due to lower nutrition levels. Male blackbuck was found to forage 67% compared to 58% by females. This difference was attributed to larger body size in males, and the upcoming rutting/lekking season. No difference was found between nilgai males and females, except usage by females was slightly more in high nutritional areas. Female nilgai were found to become more selective in summer, by increasing their foraging time from 43% to 55%. But no difference in habitat usage was found, possibly due to sustenance from Prosopis juliflora pods. Blackbuck were found to spend more time foraging (53%) compared to nilgai (43%). This was due to blackbuck being more selective in the prevailing drought conditions, while nilgai were possibly supplementing their diet with P Juliflora pods. Differences between the two species in temporal allocation of foraging time was found which was ascribed to difference in gut capacity. No seasonal differences were found between the two species, except that nilgai were found to be using high nutrition areas. Nilgai were found to be more selective nutritionally than blackbuck, possibly due to nilgai being an intermediate feeder compared to blackbuck, which are coarse bulk feeders.
