Background information.—Historically, the Powell River supported abundant and diverse populations of freshwater mussels. In recent decades, mussel density and species richness have declined and many freshwater mussel species are listed as either State or Federally threatened or endangered species. Environmental degradation from coal mining has been identified as one of the drivers of this decline. An example is the 1996 Lone Mountain slurry spill that directly affected mussel populations, as well as their host fish species. Freshwater mussels feed by filtering small particles from water, thereby improving water quality and providing an essential ecosystem service in rivers and streams. Mussels also serve as a food...

The Agassiz Beach Ridges landscape is located in the Red River watershed of northwestern Minnesota and falls and is within the larger Prairie Pothole Region (PPR). The PPR has been identified as being responsible for producing 50–80 percent of the continent’s waterfowl while accounting for only 10% of the available breeding habitat. It is estimated that less than 1% of Minnesota’s historic native prairie remains intact, with much of the remnant prairie scattered about in small clusters. Restoration of key sites within this landscape has been identified as the most important strategy to create a contiguous expanse of prairie/wetland mosaic and improve the ecological functioning of these systems. In the fall of...
