| 英文摘要 | The Baer's pochard ( Aythya baeri ), a migratory duck, used to be widespread in northeast China and eastern Russia, where it would breed, and in central and southeast Asia, where it would migrate for the winter ([ 1 ][1]). However, in recent years, the Baer's pochard population has decreased to between 150 and 700 Critically Endangered individuals ([ 2 ][2], [ 3 ][3]). China, as the primary residence of Baer's pochard ([ 3 ][3]), must take more protective measures to alleviate the threats to the species and prevent their extinction.
Anthropogenic activities have exacerbated the rapid decline of the Baer's pochard population. Wetlands are the duck's primary habitats and breeding grounds, but 33% of wetlands in China were lost between 1978 and 2008 ([ 4 ][4]). Environmental pollution has killed Baer's pochards and further restricted their habitats ([ 5 ][5]). Human activities such as fishing, illegal hunting, and picking up bird eggs have disrupted Baer's pochard populations and threatened their breeding ([ 5 ][5]).
The Baer's pochard is an important species in the biosphere and vital for maintaining biodiversity and freshwater ecosystems. Urgent and coordinated action from government and the public is required to protect this species. The Chinese government should update the National Key-protected Species List, where the Baer's pochard is still listed as a lower-priority class III protected species ([ 6 ][6], [ 7 ][7]). Local governments must strictly enforce the Wildlife Protection Law of China to stop illegal hunting and trade ([ 8 ][8]) and increase the investigation and monitoring of the Baer's pochard population, distribution, and habitats ([ 9 ][9]). China should also promote the protection and restoration of the inland freshwater wetlands that serve as the duck's primary habitats by strengthening the management of wetland nature reserves and improving the infrastructure of wetland parks. The government, scientists, and the public must work together to control China's pollution ([ 10 ][10]). Finally, the government should work to raise the public's awareness of wildlife protection.
