Tracing origins of waterfowl using the Saskatchewan River Delta: Incorporating stable isotope approaches in continent-wide waterfowl management and conservation

Using river flow management to improve wetland habitat quality for waterfowl on the Mississippi River, USA

In an effort to improve wetland conditions on the highly regulated Upper Mississippi River, the U.S. Army Corps of Engineers conducted an experiment that involved using navigation dams to restore the stable, summer low water portion of the natural flow regime that would expose soil and permit establishment of moist-soil plant species.
