Photo Credit : Pankaj Chandan/WWF-India Preface This report on Black-necked Crane is the result of intensive studies and surveys in the harsh and unique environment of Ladakh. There are several fi ndings which will be of great interest to ornithologists and particularly people working on cranes. The report takes into account the interest of the general reader and therefore has the fi rst two chapters accounting for general information on the cranes of the world and the Black-necked Crane respectively. The essence of the report lies in the chapter giving account of the survey observations from almost all the wetlands of eastern Ladakh, where the Black-necked Cranes are known to breed and feed. Such an exhaustive survey is the fi rst ever to be conducted in all the 22 wetlands in this region. The information generated from the current survey has been put in perspective against past studies and a detailed analysis has been carried out. The section on the threats to the breeding cranes and the fi nal chapter on recommendations should be of particular interest to conservation planners. This report puts into one place most of the important research related to status, breeding productivity and conservation of the Black-necked Crane in the Ladakh region of India. It is hoped that the report will not only be a source of reference for researchers but also will be of help to planners and other stakeholders in conservation and management of the species and its habitat. It is also hoped that this research will inspire further in-depth work on this unique species and the ecosystems that support it. Authors Black-necked Crane - Status, Breeding, Productivity and Conservation Acknowledgements A study like this spanning over years under hostile climatic conditions and challenging terrain of Ladakh can never be successful without the whole hearted support of numerous individuals and organizations. We have tried our best to thank all those who have contributed in one way or the other, in making this study possible. We are greatly indebted to all the organizations, agencies and individuals in Ladakh, for their cooperation and support during various stages of the study. Our special thanks to Thupstan Chhewang, former Chief Executive Councillor, Ladakh Autonomous Hill Development Council (LAHDC), currently Member of Parliament from Ladakh; Rigzin Spalbar, Chief Executive Councillor, LAHDC; Tashi Dorje, former Deputy Commissioner, Leh; Sonam Lundup, former SDM, Nyoma; Mohd. Abbas, Forest Range Offi cer, Nyoma; M P Singh, Engineer, Indian Institute of Astrophysics; who guided us and facilitated the research at all stages. We would like to thank the Indian Army and the Indo-Tibetan Border Police (ITBP) for their support and participation, which did not end with the study; the defence forces have pledged to continue supporting the conservation of Black- necked Crane.

Last but not the least we greatly appreciate the warmth and hospitality of the people of Ladakh which made the hostile conditions seem hospitable and our work possible. Authors Executive Summary Ladakh dotted with some of the world’s most unique and spectacular wetlands, also holds the distinction of being the only known breeding ground of Black-necked Crane, Grus nigricollis in India. Few studies which formed the basis for this initiative, have touched upon only some aspects of the ecology of the cranes, the reasons for which could range from hostile climatic conditions to inaccessibility of the region. WWF-India has been working towards conservation of high altitude wetlands in the Ladakh region and has identifi ed the Black- necked Crane as a priority species owing to its critically endangered status. Under this initiative, WWF in collaboration with the Department of Wildlife Protection, Jammu and Kashmir conducted the study for fi ve consecutive seasons starting from May 2000 to November 2004 on the breeding population of Black-necked Crane and covered virtually all the potential wetlands in Ladakh. Regular surveys were conducted and the observations were analysed to fi nd out breeding success and productivity. The analysis was made using an established methodology and the results indicate that though the population seems to be increasing, the overall breeding productivity is declining. The increase in the population is due to the discovery of new breeding sites and populations and the decline in breeding success is due to increased human activities, and resultant secondary impacts, like direct killing by dogs as well as pressure on habitat because of unplanned developmental activities. The study indicates that incubation period and the fi rst few weeks after hatching are the most crucial periods in the breeding cycle of the Black-necked Crane in Ladakh. Thus, immediate measures need to be taken to ensure that no disturbance is caused to the birds during the breeding season, especially the incubation period.

The Crowned Crane, however, lacks this development and consequently does not produce the trumpet-like calls, and sounds instead rather plaintive. Male and female are similar in size and plumage.
