We adopt a hindcast simulation approach comparing wetland conditions between two 30-year periods (1946–1975; 1976–2005) to determine if recent climate warming in the region has already resulted in changes in wetland condition. Modeled wetlands in the Prairie Pothole Region (PPR's) western Canadian prairies show a recent trend toward less dynamic vegetation cycles, which already may have reduced the productivity of hundreds of wetland-dependent species.
