"If the panda cannot mate with those from other habitats, it may face extinction within two to three generations," said Fan Zhiyong, Beijing-based species programme director for WWF. "We have to act now."
The risk of inbreeding is increasing, threatening to reduce the panda's resistance to diseases and lowering its ability to reproduce, the paper said. Fan said that highways pose major restrictions on the panda's free movement. "We may have to give up building some infrastructure," Fan said. "I don't know the solution to this problem."
There are about 1,590 pandas living in the wild around China , mostly in southwestern Sichuan , northern Shaanxi and northwestern Gansu provinces. A total of 180 have been bred in captivity, according to earlier reports.
