I compared bird assemblages in 97 restored and 85 natural wetlands using modified point counts. In 30 (15 restored) of these wetlands, I compared plant communities using quadrat-sampling techniques and amphibian abundance via trapping. Plant communities and amphibian abundance wee similar in restored and natural wetlands in both provinces. In Alberta, bird assemblages were comparable in both wetland types.
