Abstract
My objectives were to evaluate different fish farm management strategies effecting waterbird composition, and provide management recommendation for Sitsao Wildlife Refuge in Tainan reference to the surrounding fish farms. A long-term (January 2004-February 2006) and short-term data (September 2005-February 2006) were obtained. Results indicated that shallow-water fish farms have the highest richness, evenness and diversity; deep-water fish farms have the highest beta turnover. Deep-water and abandoned fish farms preferable habitats for egret, rail and ducks, while shallow-water fish farm and refuge are major habitats for shorebirds. And the operation tactics of shallow-water fish farms seems to provide suitable habitat for shorebirds just in time. According to the surrounding habitat condition and future trends, refuge should set shorebird as the first conservation priority and provide habitat with wetter soil, higher salinity, and lesser vegetation coverage.
