    Factors affecting habitat occupancy of tiger in the Terai Arc landscape, India
    (Wildlife Institute of India, Dehradun, 2009) Rajapandian, K.; Goyal, S.P.; Qureshi, Qamar
    The goal of this study, therefore, was to identify the factors affecting the distribution of tiger and assess the distribution of suitable habitat patches and the connectivity between these patches for successful dispersal in the Indian part of TAL. In the present study developed GIS probability models for tiger and its prey species and a spatially explicit individual-based dispersal model (SEIBM) for tiger in order to identify and assess the factors which are affecting the occupancy of tiger and subsequently predict potential suitable habitats and estimate the connectivity between the fragmented subpopulations in the Indian as well as between Indian and Nepal part of TAL. Data were collected on presence/absence of four wild ungulates (sambar Cervus unicolor, chital Axis axis, nilgai Boselaphus tragocamelus, and wild pig Sus scrofa), which are important prey species of tiger in two phases during the period between 2002 and 2006. The results of this study, in addition to contributing to the knowledge on factors affecting suitable habitat distribution and dispersal of tiger, have many implications for conservation of tiger in the Indian part of TAL. This study has also identified critical areas needed for management initiatives for functional unit of tiger conservation in the TAL.

    Development of spatial database in Geographical Information System Domain for Bandhavgarh Tiger Reserve and assessment of land use/land cover changes.
    (Wildlife Institute of India, Dehradun, 2008) Lal, Panna; Mathur, V.B.; Qureshi, Qamar
    The study on “Development of spatial database in Geographical Information System Domain for Bandhavgarh Tiger Reserve and Assessment of Landuse/Landcover Changes” was carried out between 2001 and 2006. The major objectives of the study were (a) Mapping of major vegetation communities using remotely sensed data, (b) Assessment of changes in landuse/landcover using time series analyses with a focus on areas from which villages have been relocated as part of the ecodevelopment initiative (c) Development of a resource database on ecological and management attributes for management of Bandhavgarh Tiger Reserve. The study has covered the physical, floral and faunal aspects of Tiger Reserve.

    Spatial patterns of species richness and distribution in breeding land birds of the Central Indian Highlands.
    (Wildlife Institute of India, Dehradun, 2006) Jaypal, R.; Qureshi, Qamar; Chellam, Ravi
    Variations in number and distribution of species in space constitute one of the fundamental themes in ecological research. It is being increasingly recognized that studies on species diversity at regional scale are essential to understand the mechanisms of maintenance of biological diversity. Emergence of macroecology, where large-scale ecological phenomena are examined to test biogeographical hypotheses, has considerably widened the scope of these approaches to include application of empirical patterns in finding solutions to conservation issues. This study, adopting this acroecological framework, investigates the spatial patterns in species richness and distribution of breeding land birds in central India. 2. The study was conducted across the Satpura and Vindhya Ranges, collectively known as Central Indian Highlands, in Madhya Pradesh, India between March, 2002 and September, 2005. Bird species composition is found to be primarily determined by vegetation structure at regional level and by floristic composition at local scale. This finding is consistent with earlier observations that birds respond, in their species composition, to vegetation structure across habitats and to vegetation composition within habitats. The species-area relationship in central Indian birds is best described by power function curve with a slope of 0.12. The acutely low slope points to the extremely sparse nature of spatial gradient in bird species diversity of Central Indian Highlands. The findings of the study clearly illustrate the bias in PA network that a single-species approach can potentially bring about. The recent rediscovery of the critically endangered Forest Owlet (Heteroglaux blewitti), after a gap of 113 years, from these low-rainfall dry deciduous forests highlights the importance of extending adequate protection to all major biomes and the need for multi-species approach in design and maintenance of an efficient PA network.

    Aspects of ecology of Hangul (Cervus elephas hanglu) in Dachigam National Park, Kashmir, India.
    (Wildlife Institute of India, Dehradun, 2006) Ahmad, Khursheed; Sathyakumar, S.; Qureshi, Qamar
    The Hangul or Kashmir Stag (Cervus elaphus hanglu) is a highly threatened species that has a restricted distribution confined to the Kashmir region. The Hangul is a one of the four eastern most subspecies of Red Deer of Europe (Cervus elaphus) and belongs to order Artiodactyla (even-toed animals) and family Cervidae or deer family. Compared to a very wide global distribution of Red deer, the Hangul has had a limited global distribution. Hangul were once distributed widely in the mountains of Kashmir in an arc of 40 Km extending from Karen in Kishenganga catchments in Bandipora over to Dorus in Lolab valley and Erin catchments in Bandipora to Chinab valley in Kishtwar. Some population of Hangul also occurred in Chamba district of Himachal Pradesh. However, during the recent past Hangul appears to have drastically declined from its past distribution range, possibly due to large scale biotic pressures owing to poaching, habitat fragmentation and degradation. At present the last surviving population of Hangul occurs only in 171 Km2 Dachigam National Park, although some relic populations also occur in the adjoining areas. The population of Hangul in Kashmir in 1900 was 3,000 and in 1947, there were 2,000 Hangul still surviving. But ten years later, the population got drastically reduced to about 400 individuals, and in 1970 Hangul population estimated was 140 - 170. The recent censuses carried out by the State Wildlife Protection Department in 2004 puts the Hangul population between 209-243 individuals. The most alarming threat to Hangul in Dachigam has been reported to be the excessive over grazing in the alpine meadows of Upper Dachigam by livestock including sheep and goat of the Government Sheep Breeding Farm located in Dachigam National Park. The past studies carried out in Dachigam National Park have shown that the range of Hangul In Dachigam National Park is restricted to Lower Dachigam with eastern boundaries at Gratnar, Waskhar and west of Dagwan. Keeping in view the given background and based on my preliminary surveys in in the first year of this study, the intensive study was carried out upto the above given boundaries of Lower Dachigam. There have been very little studies on Hangul compared to extensive studies carried out on its conspecifics Red Deer and Elk, and Himalayan Ungulates. There is still a lack of baseline information on the aspects of Hangul ecology prerequisite of its effective management and conservation planning. This stl1dy was as such initiated after a wildlife research gap of about 15 years in Kashmir valley in general and Dachigam in particular. This study was aimed at enhancing our scientific knowledge on the aspects of Hangul ecology such as population, habitat use and feeding ecology which are prerequisite of its effective long term management and conservation planning. During the study period (February 2001 to December 2004) a total of 693 surveys were carried out in these transects and survey blocks putting a total of 5668 km and 1839 hours effort, and a total of 326 Hangul sightings were recorded. All these Hangul sightings were recorded in lower Dachigam in an area of 41.20 km2 out of the total area of 171 Km2 of Dachigam National Park.
