Drainage of Prairie Pothole Wetlands Can Increase Flooding and Degrade Ecosystems

The drainage of small wetlands can decrease wildlife habitat and may contribute to flooding in the Prairie Pothole Region (PPR), according to a recent U.S. Geological Survey study.    USGS scientists analyzed data on 141 large PPR wetlands in North Dakota from the 1930s through 2010, and found that they have increased significantly in size. Most …
