Restore or create inland wetlands Bird Conservation

A replicated, controlled study in 1992-1994 in wetlands in the Lake Ontario and St. Lawrence River plains, New York State, USA (Brown & Smith 1998), found lower species richness and densities of wetland birds on restored wetlands compared with natural wetlands (6 species/ha and 15 birds/ha for 18 restored sites vs. 8 and 20 for eight natural sites). This pattern was stronger for wetland dependent species. Restored sites also had community compositions more similar to other restored sites than to natural wetlands. Birds were surveyed with an unlimited-radius point count within each wetland each year during the breeding season.
