migrating and emigrating pandas

the associated press reports that pandas in southwestern china are being forced to move as the bamboo that they eat is in its regenerative phase and thus there are massive food shortages. henry sanderson writes:

"Most of the pandas' favorite arrow bamboo in a 217,000 square-mile region of Sichuan province is going through a once-in-60-year cycle of flowering and dying before regenerating, said Yang Xuyu, deputy head of the province's Wild Animal Preservation Station. The pandas are moving to other areas of Sichuan, which has about 40 reserves of various sizes. "No wild panda has been found dead of starvation," said Yang. But more than 80 percent of bamboo in the affected region, called Ruoergai, is now unfit for the animals to eat, he said. Pandas will not touch the plant once it flowers.

About 1,200 pandas — 80 percent of the surviving wild population in China — live in several mountainous areas of Sichuan. Hundreds of pandas died of starvation in Sichuan in the 1980s when arrow bamboo in some reserves flowered and then died. Pandas derive most of their nutrition from arrow bamboo and can starve once the plant enters its dying-off stage. The bamboo produces seeds before dying, and takes 10 to 20 years to grow back. Yang told a conference on panda survival in Chengdu, Sichuan, on Sunday that a shrinking habitat due to farming and industrial development makes it increasingly hard for the animals in the wild to find food during the bamboo life cycle, according to the Xinhua news agency. China's forestry bureau is carrying out a panda rescue drive and working with the World Wildlife Fund to try to restore panda migration paths, Xinhua said."

on a more positive note, mei sheng (which translates as "born in the usa"), arrives safely at the wolong nature reserve in china. mei sheng was born in the san diego zoo, and returns as part of the agreement with china that allowed his parents to go to san diego in the first place.
