XI'AN - China's conrvation work for the endangered crested ibis（朱鹮）is facing new challenges, including an increasing death rate due to inbreeding（同系繁殖）, and the conflict between the need to expand natural habitats and local communities' economic interests, bird experts have warned.
瀛湖中学The crested ibis, once widespread in Japan, China, Russia and the Korean Peninsula, almo
st became extinct in the first half of the 20th century.
Before 1981, when ven crested ibis were accidentally found in Yangxian county, in Northwest China's Shaanxi province, academics thought the species had been extinct in China for almost 17 years.
Due to the huge effort put into species protection since 1981, the number of crested ibis in China has rin to an estimated 1,617, including 997 in the wild, the State Forestry Administration said at a meeting on crested ibis protection in Xi'an on Monday.

However, although the ibis population exceeds 1,000, the birds are still not free from the threat of extinction, said Fang Shengguo, director of the State Conrvation Center for Gene Resources of Endangered Wildlife at Zhejiang University.
Ornithologists ud inbreeding in the early stages of protection so that numbers of the precious birds could increa quickly, but that method had conquences, Fang said.
"Studies have proved that as a result of inbreeding, crested ibis have the lowest genetic d

"It means a high death rate and more physical defects for hatched chicks."
The government should collect genetic information from all crested ibis and establish a genetic databa as soon as possible, then design a scientific mating plan for the species, Fang said.
So far, about 90 percent of crested ibis live in Shaanxi province, and fewer than 140 ibis live in three zoos in other parts of the country, including Beijing Zoo, according to Liu Dongping, an assistant rearcher at the National Bird Banding Center of China, which is affiliated to the Chine Academy of Forestry.
The bird has lost the ability to migrate, he said, adding that if an unexpected natural disaster occurred in Shaanxi province or an infectious dia spread through the area, the ibis population could be greatly reduced.
Experts also warned that the incread population of ibis, whether in the wild or in captivit崔颢黄鹤楼

y, requires a larger and more varied natural habitat.
Rampant hunting, the massive loss of habitat caud by deforestation and the overu of pesticides, which killed aquatic(水生的) incts on which the ibis feed, are believed to be the main reasons for the sharp reduction in the ibis population before 1981.
So, in 1983, a State-level natural rerve was t up in Shaanxi province to protect the bird. But the struggle for living space between human and animal has never stopped, said Lu Baozhong, deputy director of the Shaanxi Crested Ibis Conrvation Station.
"For example, ibis often look for loaches in farmers' rice fields. Sometimes their claws trample the rice edlings. In another ca, villagers discovered some land with abundant mineral resources which happened to be a habitat for ibis," said Lu, who has devoted 30 years to ibis protection.
A long-term win-win solution for ibis and local communities needs to be developed, one that would provide ecological compensation for local residents, Lu said.
