The Department of Natural Resources today announced that 2013 will mark the 18th year of the annual statewide Frog and Toad Survey coordinated by the DNR Wildlife Division. This year, the DNR hopes to get valuable survey assistance from both veteran and first-time volunteers.

Declining populations of frogs, 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 DNR’s survey coordinator.

The surveys are conducted by volunteer observers along a statewide system of permanent survey routes, each consisting of 10 wetland sites. Observers visit the sites three times during spring – when frogs and toads are actively breeding – and listen for calling frogs and toads at each site, identify the species present, and make an estimate of abundance.

“We could still use some new volunteers in all parts of the state. Please consider joining us for a fun, educational time every spring and run a route,” said Sargent. “The continued success of the program is dependent on strong volunteer support.”
