The San Diego Zoo in the United States has joined relief efforts to aid a giant panda base in Sichuan Province which was hit hard by the May 12 earthquake.

Eight giant pandas from quake-hit Sichuan Province are transferred to the national capital Beijing so that the animals can have a better breeding and recovery environment.

"Our colleagues at the Wolong center have already shown tremendous heroism in their efforts to save the giant pandas in the wake of damage done by the earthquake," said the coordinator Dr Ron Swaisgood.

He is co-leader of the conservation center at the San Diego Zoo, about 128km south of Los Angeles.

Donations to a relief fund for the China Giant Panda Protection and Research Center in Wolong can be made at the San Diego Zoo's giant panda conservation center or online at www.sandiegozoo.org, said Dr Swaisgood.

The Wolong center is only 30 km from the epicenter of the 8.0-magnitude quake. A total of 14 giant pandas were removed from the Wolong center due to shelter damage and food shortage. Two of the 53 pandas kept at Wolong center were injured and two are still missing.

Yesterday, eight pandas selected by netizens to add cheer to the Beijing Olympics arrived in the capital from Wolong. The 2-year-old pandas will stay at Beijing Zoo.

Wang Pengyan, an official from the Wolong center, said "The pandas have recovered from the panic and are all in good condition."
