Aquatic Mammal Surveys for St. Louis River AOC


This is a two year project to conduct population surveys of aquatic mammals within the estuary of the St. Louis River Area of Concern (AOC) to assess the status of the Degraded Fish and Wildlife Populations Beneficial Use Impairment (BUI).


Conduct surveys of aquatic mammals (beaver, mink, otter, and muskrat) to determine current populations. The data will be used to determine future actions for the Degraded Populations BUI in the AOC (either removing the BUI or guiding the selection of projects to address populations if needed).
