Abstract:

An investigation on status of waterbirds in two sorts of plots respectively with mangroveforested and mangrove\| deforested in Hainan Island was conducted consecutively in winters from 2003 to 2005 to facilitate the conservation and management of mangrove forests in Hainan Island. The results showed that the waterbird species,numbers and diversity were much higher in mangrove forests wetlands than that of mangrove deforested plots,probably due to a higher density of invertebrate animals on the mudflat of mangrove forests,which attracted the more waterbirds to feed on. Whereas there was no marked difference in the numbers of ducks,plovers and small shorebirds such as Rufousnecked Stint,Temminck's Stint between the two habitats,the numbers of egrets and herons were significantly higher on mangrove forests wetlands,and the numbers of some middle and larger sandpipers,such as Common Redshank,Common Greenshank and Marsh Sandpiper,on mangrove forests wetlands were higher than that of mangrovedeforested plots. Finally,some conservation suggestions were put forward to strengthen the conservation and management of mangrove forests in Hainan Island.
