  1. Restore or create inland wetlands

    A replicated, paired site study from May-July in 1997-1998 in 39 pairs of restored and natural wetlands in North and South Dakota, USA (Ratti et al. 2001) found that restored wetlands exhibited equal, and often greater, avian abundance, species richness and diversity. There were no significant differences in overall bird abundance, species richness or diversity; waterfowl breeding pair density or upland species richness between restored and natural wetlands. However, Canada goose Branta canadensis, mallard Anas platyrhynchos, redhead Aythya americana, and ruddy duck Oxyura jamaicensis exhibited significantly higher densities on restored wetlands. Total area bird counts were performed four times on each wetland.
