Caofeidian wetland in Hebei Province is rich in types: freshwater wetland, seawater wetland, reservoir wetland, reed and fishery wetland, brine wetland and so on. Such a rich habitat attracts hundreds of thousands or even millions of migratory birds to inhabit, forage and reproduce there every year.


At the end of March this year, China Biodiversity Conservation and Green Development Foundation (CBCGDF) established the Community Conservation Area for fairy shrimp at Caofeidian Wetland (CCAfa). Recently, volunteers are pleased to find that tens of thousands of water birds appear in this water area every day.


On artificial bird islands, many bird nests were observed through telescopes. This has something to do with the "dual-cycle" ecological conservation model of the wetland that Caofeidian Wetland has spent more than a year exploring.


An important key species in the wetland "dual-cycle" ecological conservation model carried out by the Yellow Sea Research Institute of the Chinese Academy of Fishery Sciences is the fair shrimp, also known locally as "artemia". According to statistics, about 85% of the world's aquaculture and ornamental fish nurseries use fairy shrimp as bait, which is related to the rise and fall of the aquaculture industry. In ecological conservation, the farmer will not completely catch fish and shrimp and other creatures that grow up to eat fairy shrimp but will reserve a certain ration for birds; In addition, some birds feed directly on fairy shrimp. Moreover, fairy shrimp can also purify water quality and maintain ecological balance, which is a species of great significance to the ecosystem.


On May 7, Wang Jianmin, the director of CBCGDF Community Conservation Area for relict gulls at Tianjin and volunteers conducted an investigation in the CCA for fairy shrimp and observed an artificial bird island of about ten square meters in the ecological breeding pond. There were more than 50 bird nests and many bird eggs on it. There were also bird nests scattered around the road in the wetland. In the visual range, they could see that there were more bird nests on the larger bird island, and the number was even 70-80 nests. In total, hundreds of bird nests were observed. At present, the birds foraging, resting, roosting and breeding around the bird island include black-winged long-legged sandpiper, back-nosed sandpiper, brown sandpiper, sandpiper, curlew, common terns, white-fronted terns, etc., as well as national first-class protected animal relict gulls that feed on perennial worms in brine ponds. Now, tens of thousands or even more than 100,000 birds go there to feed and rest every day. The brine wetland in Caofeidian is of great significance to the water bird community dominated by curlew and snipe.


In order to avoid disturbing the life of the birds, volunteers observe and take photos at a distance, and record the true ecological situation to share with everyone.


The protection of Caofeidian wetland requires a comprehensive and objective assessment in many areas including wetland planning, management of protection, monitoring of protection, and scientific protection technologies. Any area should try to avoid "one size fits all" and consider human-based solutions. After all, protection is for better development.
