The Wisconsin Frog and Toad Survey (WFTS) is a citizen-based monitoring program coordinated by the Wisconsin Department of Natural Resources (WDNR), in cooperation with the U.S. Geological Survey (USGS) and the North American Amphibian Monitoring Program (NAAMP).

The primary purpose of the WFTS is to determine the status, distribution, and long-term population trends of Wisconsin's thirteen frog species. The WFTS was initiated in 1981 in response to known and suspected declines in several Wisconsin species, particularly northern leopard frogs (Rana pipiens), Blanchard's cricket frogs (Acris crepitans blanchardi), pickerel frogs (Rana palustris), and bullfrogs (Rana catesbeiana). The WFTS began annual statewide surveys in 1984 and is now one of the longest running amphibian monitoring projects in North America.
