    Status of the tigers and copredators in Central Indian landscape
    (Wildlife Institute of India, Dehradun, 2007) Jhala, Y.V.; Gopal, Rajesh; Qureshi, Qamar
    The present report forms a part of the All India Tiger Monitoring exercise undertaken on the direction of the Ministry of Environment and Forests by the Wildlife Institute of India in association with National Tiger Conservation Authority, MoEF, Government of India, and the State Forest Departments. As a part of this process, preliminary findings on the status, and distribution of tigers, co-predators and prey in the States of Rajasthan, Madhya Pradesh, Maharashtra, Chattisgarh, Andhra Pradesh and Orissa are presented. Tiger population estimates are provided for the States of Rajasthan, Madhya Pradesh, Maharashtra and Chattisgarh. For the remaining States of Andhra Pradesh, Jharkhand, and Orissa tiger population estimation is in progress and estimates will be provided at a later date. The current monitoring system for tigers, co-predators, prey and their habitat transcends beyond generating mere numbers. It is a holistic approach which uses the tiger as an umbrella species to monitor some of the major components of forest systems where the tiger occurs in India. The data and inferences generated by the system would not only serve as a monitoring tool but also as an information base for decision making for land use planning. It provides an opportunity to incorporate conservation objectives supported with a sound database, on equal footing with economic, sociological, and other values in policy and decision making for the benefit of the society. After the Sariska debacle, this system with a few modifications was recommended as a monitoring tool for the entire country by the Tiger Task Force.

    Social organization and dispersal of Asiatic lion and ecological monitoring of Gir
    (Wildlife Institute of India, Dehradun, 2006) Jhala, Y.V.; Chellam, R.; Qureshi, Q.; Pathak, Bharat; Meena; Chauhan, K.S.; Dave, C.; Banerjee, K.
    Project titled ‘Social Organization and dispersal of Asiatic lion’ was initiated in 2002 by the Wildlife Institute of India in collaboration with the Gujarat Forest Department. Continuous record of lion demographic and population parameters, ungulate density and distribution, livestock-ungulate interaction and the study of male ranging patterns and resource utilization with the help of radio- telemetry have been some of the achievements of the project in the past five years. The project had established two research-bases at Sasan Gir (West Gir) and Tulsi Shyam (East Gir) respectively to meet the added project objective of project “Ecological monitoring of the Gir” in 2003. This component included studies on livestock-wild ungulate interaction, Maldhari-lion interaction, refinement of protocols for lion monitoring and mapping of peripheral areas of Gir which were considered important by the Gujarat Forest department and The Wildlife Institute of India.

    Monitoring of Gir : A technical consultancy report
    (Wildlife Institute of India, Dehradun, 2004) Jhala, Y.V.
    This project would be a step towards capacity building of the PA management by acquisition of appropriate equipment and training in ecological, sociological and institutional monitoring. We believe that by undertaking this task in the above manner we would contribute more towards the long-term conservation of the Gir ecosystem which has been the ultimate objective of the India Eco-development project.

    Ecology of black kites Milvus migrans subsisting on urban resources in Delhi: Black kite Project Phase - III
    (Wildlife Institute of India, Dehradun, 2008) Kumar, N.; Gupta, U.; Malhotra, H.; Jhala, Y.V.; Sergio, F.; Gosler, A.; Qureshi, Q.
    The research team working in the National Capital territory, since December 2012, and through major funding support from the Raptor Research and Conservation Foundation (RRCF), envisioned a long collaborative term study around the urban adaptations of a large raptor, the Black Kite Milvus migrans. Supervised since its inception by Profs. Y. V. Jhala and Q. Qureshi from the Wildlife Institute of India, and Dr. F. Sergio of CSIC, Spain, this project is a unique attempt in the Sub-Continent to holistically unravel the adaptations around Black Kite’s densest urban settlement in the world. We have now established how human cultural practices and attitudes may well be the most defining dimensions of the urban niche of synanthropes like Black Kites (Kumar et al. 2018). Thus, the third phase (August 2016 – July 2018), was a comprehensive assessment of the breeding ecology of Black kites, and their aggressive interaction with residents along the sampled urban gradient within the megacity of Delhi. For this, we used the habitat selection criteria of kites (Kumar et al. 2018) and inspected the behaviour of breeding kites at 101 territories (total 657 visitations), and tested their offspring defence (Kumar et al. in review). We found that defence increases with proximity to ritual-feeding sites and availability of offal, apart from progression in the breeding stage. This period also included the beginning of Phase -IV, an attempt to understand the migration of the Milvus migrans lineatus, the subspecies from the Central Asian Steppes wintering in the urban quarters of the Subcontinent from September to April every year. We deployed 13 GSM e-obs tags and 5 GSM tags from Microwave Telemetry Ltd. USA. These efforts were preceded by Phase-I of the project (December 2012 – June 2014) that focused on basic natural history observations (Kumar et al. 2014), and the Phase-II (July 2014 – July 2016) which further extended the efforts to cover more sampling units, focusing on the aspects of habitat, behaviour and population ecology. The project has now entered its intensive publication stage, as substantial data have now accumulated to enable high-level publications on international scientific outlets, with three publications lined up and ready to enter the genetic and disease components, apart from movement ecology. Finally, the project has incorporated through these initial years: (1) a remarkable amount of environmental education of Delhi citizens; (2) the Master thesis and near -completion of a PhD thesis by N. Kumar at an institute of repute (Oxford University, Department of Zoology, Edward Grey Institute of Ornithology); (3) completion of a Master program by U. Gupta at the Department of Geography of Oxford University; (4) training of more than 100 volunteers and some of them joining institutes of national and international reputation. All in all, the overall research team is extremely satisfied of all the progress and research formation attained and eager to move on to expand and intensify the project even more.
