'Ghost cat': Bronx Zoo welcomes new baby snow leopard just in time for Halloween.
Snow leopards were captured on film for the first time ever in eastern Tibet with the help of remote infrared cameras, Chinese media reported Monday.
The cameras were set up in the Nujiang River Valley, also known as the Nu River.
It is home to one of Asia's last "wild rivers" unencumbered by dams or other projects, according to the U.S.-based non-profit environmental group International Rivers.
The presence of the leopards may be a sign that local conservation efforts are working, Xinhua said.
Snow leopards are classified as a "vulnerable" species by the International Union for the Conservation of Nature, which estimates there are between 2,500 and 10,000 left in the world.
Tibet is a special autonomous region of China and has been ruled by Beijing since 1951. »
