Panda Climbing Tree in Wolong National Nature Reserve, Sichuan Province, China
China’s iconic giant panda is struggling to survive; while its numbers appear to be higher than once suspected, there are still believed to be no more than 3,000 left in the wild. Despite strenuous efforts, they also don’t breed very well in captivity; they are also susceptible to poaching in the wild. The panda has been the symbol of the World Wildlife Fund since 1961.
