The Declining Importance of the Fujian Coast, China, for Wintering Waterbirds

摘要

East China is a very important wintering region for many migratory waterbirds, but many species have suffered large population declines over recent decades. However, the limited information available oil the current and historical abundances of waterbirds in tire region Seriously limits our ability to assess the magnitude of these declines. The first comprehensive count of tire complete Fujian coastline, conducted over a three-week period in February 2006, provided the opportunity to compare data from this count with historical information on waterbird abundances along the Fujian coast obtained during the second half of the 1800s and early-1990s. Our count total of nearly I 10,000 birds of 65 species shows that the Fujian coast is still very important for waterbirds during the wintering period. We obtained abundance comparisons for 28 species of which 19 had declined greatly in the last 100150 years: four of these are globally threatened. The Anatidae group, in particular, has suffered seriouslyin diversity and numbers during the last century and this finding is consistent With observed decreases in breeding numbers. Given Population declines and the great importance of cast China as a wintering area for waterbirds (including some globally threatened species), all important priority should be to determine the current Status of the different species throughout. the region. This information will be useful ill proposing effective conservation measures including monitoring in east China. Received28 August 2007, accepted 1 April 2008.
