DNR’s annual frog survey marks 20th year
The Department of Natural Resources annual survey efforts help biologists monitor frog and toad abundance and distribution in the state.
For example, over the past 19 years Michigan has seen a decline in Fowler’s toads and mink frogs, two species that have a limited range in the state, unlike most of the other species that occur statewide. Studies suggest amphibians are disappearing due to habitat loss, pollution, disease and collection.
Volunteer observers conduct the surveys along 10 wetland sites. Observers visit these sites three times during spring, when frogs and toads are actively breeding, listening for calling frogs and toads at each site, identifying the species present and making an estimate of abundance.
“We could still use some new volunteers in all parts of the state," Sargent said. "Please consider joining us for a fun, educational time every spring and adopt a route. The continued success of the program is dependent on strong volunteer support.”
Those interested in volunteering should contact Lori Sargent at SargentL@michigan.gov or 517-284-6216 and provide their name and address.
