WETLANDSCAPES: SIZE, CONNECTIVITY AND ECOHYDROLOGY AT THE LANDSCAPE SCALE
Our research addresses questions like:
Our study in the Prairie Pothole region shows that wetland loss follows a strong pattern, with smaller, isolated wetlands being lost in much greater numbers than larger wetlands. We further showed using meta-analysis and modelling that small wetlands were more efficient biogeochemical reactors than larger ones of equivalent area -- or in other words ten 1-ha wetlands can remove more nutrients than one 10-ha wetland. This work led to multiple newspaper articles and interview in CBC radio. I am a member of the USGS Powell Center Group on Wetland Connectivity and the Global Wetland Ecohydrology Network, and as part of these groups I have contributed to multiple papers in high-impact journals on the need for protection of geographically isolated wetlands.
