In 2017, staff from the Illinois Natural History Survey continued to monitor translocated populations of two federally-endangered freshwater mussel species in the Vermilion River basin (Wabash River drainage). Through 2017, a total of 3,699 Northern Riffleshell (Epioblasma rangiana) and 4,166 Clubshell (Pleurobema clava) have been translocated to the Middle Fork and Salt Fork Vermilion rivers in the Vermilion River basin, Champaign and Vermilion counties, Illinois, and these translocated animals have been monitored since being moved to Illinois. This end-of-the-year report summarizes the activities for the 2017 calendar year, and includes two reprints and a galley of a third paper summarizing data from this project. This relocation project is being funded, in part, by a natural resource damage assessment settlement (Hegeler Zinc—Lyondell Basell Companies) to the U.S. Fish and Wildlife Service and to the State of Illinois, and by the U.S. Fish and Wildlife Service’s Ohio River Basin Fish Habitat Partnership.
