On the Importance of Introducing Crested Ibis into the Coastal Wetland of Yancheng,Jiangsu Province
The crested ibis(Nipponia nippon)is a national first-class protected animal and a globally endangered bird.China is the only country in the world with wild crested ibis distribution.Crested ibis was once distributed in the east coast of China,wintering in the east,southeast coast,Taiwan and other places,with migration habits and the ability to find food in the coastal mudflat.Due to fac-tors such as environmental degradation,habitat loss,and natural enemies,the migratory population of Crested Ibis has become extinct,leaving only 7 wild non migratory populations in Yangxian,Shaanxi Province.After 40 years of conservation,the in situ and ex situ conservation of Crested Ibis has achieved outstanding results in recent years,making it a successful example of saving endangered spe-cies in the world.However,the existing Crested Ibis population has a narrow distribution area,low genetic diversity,and a lack of mi-gration ability,making it difficult to cope with harsh environments and the threat of infectious diseases.The reintroduction of crested i-bis into the coastal mudflat habitat in eastern China is a brave attempt to rebuild the crested ibis migratory population and improve its a-bility to cope with changing environments.This article aims to introduce the historical development,conservation status,and discuss the importance of reintroducing the crested ibis into coastal wetlands.
