LANSING, Michigan — Michigan officials are seeking volunteers to join the annual frog and toad survey, entering its 20th year.

Scientists report a worldwide decline in amphibian populations since the 1980s resulting from habitat loss, pollution, disease and collection.

Michigan's survey is conducted along a statewide network of routes, each with 10 wetland sites.

Observers visit the sites three times each spring, when frogs and toads breed. They listen for calls, identify the species and estimate how many individuals there are.

Department of Natural Resources biologists analyze the data to monitor frog and toad abundance and distribution.

Survey coordinator Lori Sargent says previous surveys identify trends and help guide efforts to slow down the decline of some species. She's reachable by calling 517-284-6216 or by emailing SargentL@michigan.gov.
