Item Mapping of the protected area (PA) and surrounding areas in Pench Tiger Reserve, Madhya Pradesh(Wildlife Institute of India, Dehradun, 2000) Sankar, K.; Qureshi, Q.; Mathur, V.B.; Mukherjee, S.K.; Areendran, G.; Pasha, M.K.S.In this study the task included the preparation of baseline maps of Pench tiger reserve and surrounding areas consisting of features relevant to PA management and ecodevelopment activities. The maps were digitized and incorporated in Geographical Information System (GIS) domain. As part of assignment the spatial database developed for the Pench tiger reserve has been installed in the PTR office at Seoni.Item Ecology of tigers in Pench Tiger Reserve, Madhya Pradesh and Maharashtra(Wildlife Institute of India, Dehradun, 2013) Sankar, K.; Qureshi, Q.; Jhala, Y.V.; Gopal, R.; Majumdar, Aniruddha; Basu, S.The present study aimed to map land use/land cover patterns and to assess spatial structure and configuration of landscape; structure and composition of vegetation types in landscape; and varies ecological aspects of tiger (Panthera tigris) in a tropical deciduous forest of Central India from 2005 to 2013. Prey species availability was estimated using line transect method in an intensive study areas of 410 sq km between January 2007 and June 2012.Item Ecology of Dhole (Cuon alpinus Pallas) in Central India(Wildlife Institute of India, Dehradun, 2006) Acharya, Bhaskar B.; Johnsingh, A.J.T.; Sankar, K.The objectives of the project in Pench Tiger Reserve, Madhya Pradesh, were to estimate the seasonal abundance of dhole prey species, the diet of the dhole packs from their scats and kills, to determine patterns of habitat use and range sizes of dhole packs, to estimate temporal changes in size and composition of dhole packs, and the processes behind such changes, to screen captured dhole and other animals for diseases, and estimate the probability of contact with potential disease carriers, to devise standardised protocols for dhole population surveys and to estimate dhole population size for the Tiger Reserve.Item Reintroduction of Gaur (Bos gaurus gaurus) in Bandhavgarh Tiger Reserve, Madhya Pradesh, India(Wildlife Institute of India, Dehradun, 2011) Sankar, K.Item Evaluation of prey availability and habitat suitability for tigers and its ranging patterns in Sanjay Tiger Reserve, Madhya Pradesh(Wildlife Institute of India, Dehradun, 2017) Ramesh, K.; Sankar, K.; Kumar, Deleep; Nigam, Parag; Qureshi, Qamar; Raman, K.; Rajasekar, R.; Chaudhuri, Sankarshan; Sundaram, Snehaa; Hazra, PoushaliTiger conservation in human dominated landscape such as Sanjay Tiger Reserve (STR) has always been challenging for the managers and conservation planners. Anthropogenic factors have affected the area negatively, causing habitat degradation, depletion of prey base and unviable tiger population. STR is considered to be low density tiger population area and require recovery strategy, involving translocation from other areas, since natural colonization is not possible to boost the population to viable state. As a precursor to active population recovery, the project was conceived and implemented to establish baseline on prey availability and habitat suitability for tigers, which also involved understanding ranging patterns of tigers using radiotelemetry. Prey availability in terms of density of wild ungulate was estimated and was found to be low (8.2 ± 0.8 animals per km2), but there is an increasing population trend during the study period (2014- 2017), largely owing to active protection measures. Amongst the wild ungulates, density of chital was the highest (3.0±0.6/km2) followed by wild pig (2.0±0.6/km2), nilgai (1.8±0.3/km2), chinkara (1.1±0.3/km2) and four horned antelope (1.0±0.4/km2). Livestock (11.6±5.5/km2) was the most abundant animal using the reserve throughout, also contributing to prey base to some extent. Home range of one radio-collared adult male tiger was estimated to be 208.6km2 during May 2015 to July 2015 and the animal got killed to a territorial fight with another male tiger. Similarly, home range of radio-collared (captive-raised) tigress was estimated to be 154.1 km2 during October 2016 - May 2017. Exploring large areas could be attributed to limitation of mate choice and a depleted prey base. Habitat suitability of tiger was assessed based on habitat covariates and it was found that 44% of the total area of tiger reserve is potentially suitable habitat in the current status of prey availability, but the suitability can increase to 61% if prey base can be restored in other areas of the reserve. Carrying capacity of tiger was determined for STR based on the current prey density. It was found that STR can support 11 tigers in this present situation. Population Viability Analysis (PVA) with the carrying capacity of 11 tigers and current population (four individuals, one adult male, two adult females and one juvenile) of tiger in STR showed a poor survival probability (0.12 ±0.03) over a time span of 25 years. However, given the availability of habitat space and potential to increase prey base, doubling of carrying capacity from 11 to 22 tigers is possible with a supplementation of two tigers in every three years until year ten and it will ensure very high survival probability (0.87±0.03). Active recovery strategy should target the futuristic carrying capacity and management actions would have to be geared towards this. In this context, active population recovery and long-term monitoring strategy has been proposed towards successful population recovery and establishment of viable tiger population, along with other habitat covariates.
