Bird diversity and the conservation value of a new Ramsar site: Guangdong Haifeng Wetlands,China

Wetlands are critical habitats for birds. However, wetlands are being degraded at an accelerating rate due to global human activity, and a disproportionate fraction of wetland‐dependent bird species are in decline. We evaluated the conservation value of a new Ramsar site, Guangdong Haifeng Wetlands, China, for birds, by comparing bird communities (using line transect data) in 3 different districts: Gongping, Dongguan Lian'anwei and Dahu. We recorded 139 species of birds, including 26 species that are protected at a national level. Dahu had the highest species richness and diversity, whereas Dongguan Lian'anwei had the highest abundance of birds and the lowest species diversity. Finally, Gongping had both the lowest species richness and the lowest abundance. The endemism of constituent species differed among districts, and the bird communities were complementary. There were significant seasonal differences in the species richness and the number of individuals. Spring had the highest species richness and diversity. The present study identifies the high conservation value of Haifeng Wetlands for both waterbirds and terrestrial birds. Our findings suggest that conservation efforts in Haifeng Wetlands and other wetlands should focus not only on wintering migratory birds, but also on resident birds. To accomplish effective conservation, we should consider the reserve and surrounding wetlands as a whole, incorporating ecological research, education and local economic development.
