In 2000, the FWSs Environmental Contaminants Program currently Environmental Quality Program received funding as part of the Department of Interiors Amphibian Initiative. The surveys originally done in Regions 3 and 5 1997 were refined and expanded into a nationwide survey of over 43 refuges in 31 states. The six original locations in Region 3 included Mark Twain NWR Annada District renamed Clarence Cannon NWR MO, Mark Twain NWR Brussels District renamed Two Rivers NWR EL, Union Slough NWR IA, Ottawa NWR OH, Rydell NWR MN, and Fergus Falls WMD MN. More than 1,600 frogs were collected and examined. Ninetyeight percent of these frogs were Ranids with northern and southern leopard frogs accounting for the majority.
