Restore wetland
A replicated, site comparison study in 1999–2000 of 97 restored wetlands in aspen parkland in Alberta and Saskatchewan, Canada (Paszkowski, Puchniak & Gray 2001) found that restored wetlands had similar amphibian abundance to natural wetlands, suggesting that restored wetlands provide suitable habitat for amphibians. A total of 4,086 wood frogs Rana sylvatica, boreal chorus frogs Pseudacris maculata and tiger salamanders Ambystoma tigrinim were captured over the two years. Amphibians, in particular wood frogs, were found in similar numbers in restored and natural wetlands. From 1987, wetlands were restored by installing ditch plugs. Amphibian presence/absence was recorded in 97 restored and 85 natural wetlands. In 1999, seven and in 2000, 11 restored and natural wetlands were monitored intensively. Pitfall (19,431 trap nights) and minnow traps (6,794 trap nights) were used to compare species between restored and natural ponds.
