A WILDLIFE CONSERVATION SOCIETY PROGRESS REPORT BIG CATS Wildlife Conservation Society 2300 Southern Boulevard Bronx, NY 10460 wcs.org 2015 Wildlife Conservation Society Progress Reports provide you, our generous supporters, with updates and insights on core conservation activities. Together, we are securing a future for wildlife and wild places. WCS saves wildlife and wild places worldwide through science, conservation action, education, and inspiring people to value nature. WCS envisions a world where wildlife thrives in healthy lands and seas, valued by societies that embrace and benefit from the diversity and integrity of life on earth. Scientists Deploy Camera Traps to Protect Tigers Remote camera traps provide conservation scientists with valuable information that is difficult—and sometimes downright impossible—to gather by other methods. In Russia, India, and other tiger range countries, WCS teams are using this technology to monitor and protect wild tiger populations. Counting tigers has proven challenging as these forest of the Malenad Landscape in southwestern animals are elusive and often live in dense forest India to set up camera traps. Trekking up to 10 miles habitats, but monitoring is vital to successful per day through the tropical landscape, they walk conservation. We need to know how tiger numbers for months on end, setting up cameras at about today compare to past tiger numbers, how many 700 locations within nearly 2,300 square miles. tigers are born each year, where tigers are living, and how many tigers move in and out of landscapes. “Camera trapping has proven We also need to investigate factors that could be driving population changes, including threats such more accurate and reliable as a lack of prey and available forest cover due to in determining whether our deforestation, and human disturbance such as conservation action on the poaching.

Tiger Stamp Back on Sale Congress has reauthorized the sale of the Save Vanishing Species postage stamp, also known as the Tiger Stamp. Once again, it is available for purchase at U.S. Post Offices. The tamps costs 60 cents—11 cents more than a regular first-class stamp. The additional 11 cents from each stamp’s sale go directly to the U.S. Fish and Wildlife Service’s Multinational Species Conservation Funds, which support conservation programs to save tigers and other animals such as African and Asian elephants, great apes, rhinos, and turtles. Between September 2011 and December 2013 (when the stamp’s original authorization expired), the U.S. Postal Service sold more than 25 million stamps, raising more than $2.5 million for conservation at no taxpayer expense.

Their current range is limited to the remote mountains of Central Asia and parts of China, Mongolia, Russia, India, and Bhutan. WCS has a long history of snow leopard conservation, beginning with former WCS Chief Scientist George Schaller's surveys on snow leopards and their prey in the Himalayas in the 1970s. We now work in a number of snow leopard range countries, focusing on populations with ample potential to bounce back, to help this endangered species thrive in the wild once more. Afghanistan wcs’s eight years of snow leopard conservation in reported any incidents of snow leopards killing livestock Afghanistan culminated in 2014 with the declaration corralled in these structures or subsequent retaliatory of the remote northwestern district of Wakhan as the killing of the snow leopards. We hope the structures country’s second protected area—Wakhan National will continue to reduce this primary cause of conflict Park. This vast area of 4,241 square miles—25 percent between snow leopards and their human neighbors.
