Even though the national park has a resident red panda population of only about 42(in 2019) members, Project Red Panda (funded by the Central Zoo Authority) chose Singalila National Park for reintroduction of red pandas from its captive breeding program at the Padmaja Naidu Himalayan Zoological Park in Darjeeling, mainly due to reasons of proximity. Two females, Sweety and Milli, were released in November 2004. Milli was killed by a leopard, but Sweety adapted to the wild and gave birth to an offspring - the first such successful re-entry for red panda.
