LANSING (AP) -- The Michigan Department of Natural Resources is looking for volunteers to help monitor frog and toad populations.
Scientists have documented drop-offs of frogs and other amphibians worldwide since the 1980s. Studies indicate they're falling victim to habitat loss, pollution, disease and collection.
The DNR's Wildlife Division has conducted surveys the past 17 years to keep track of frog and toad abundance and distribution in Michigan. The agency is looking for volunteers to help.
Survey coordinator Lori Sargent says observers visit a network of routes around the state, each with 10 wetland sites. They go there three times during spring breeding periods and listen for frog and toad calls. The volunteers identify the species present and estimate their abundance.
