The Department of Natural Resources and Environment (DNRE) today announced that this year will be the 15th annual statewide Frog and Toad Survey coordinated by the DNRE Wildlife Division.
Declining populations of frog, toads, and other amphibians have been documented worldwide since the 1980s. Studies suggest amphibians are disappearing due to habitat loss, pollution, disease and collection.
Michigan's annual survey efforts help biologists keep tabs on frog and toad abundance and distribution in the state.
"We have collected a large, valuable data set to help us evaluate the condition of Michigan's frog and toad populations," said Lori Sargent, the DNRE's survey coordinator.
The surveys are conducted by volunteer observers along a statewide system of permanent survey routes, each consisting of 10 wetland sites. These sites are visited three times during spring when frogs and toads are actively breeding. Observers listen for calling frogs and toads at each site, identify the species present and make an estimate of abundance.
"There are only about 200 routes statewide that are active routes. We could really use some new volunteers in all parts of the state," said Sargent. "I encourage folks to consider joining us for a fun, educational time every spring and run a route. The continued success of the program is dependent on strong volunteer support."
For additional information or to volunteer, please leave your contact information for Lori Sargent at 517-373-9418, or at SargentL@michigan.gov.
