Vol­un­teers Needed for DNR Frog and Toad Sur­vey

Modern Pioneer - - News -

The Michi­gan Depart­ment of Nat­u­ral Re­sources (DNR) is seek­ing vol­un­teers through­out the state to as­sist with its an­nual frog and toad sur­vey.

De­clin­ing pop­u­la­tions of frogs, toads and other am­phib­ians have been doc­u­mented world­wide since the ’80s. Stud­ies sug­gest am­phib­ians are dis­ap­pear­ing due to habi­tat loss, pol­lu­tion, dis­ease and col­lec­tion.

Michi­gan’s an­nual sur­vey ef­forts help bi­ol­o­gists mon­i­tor frog and toad abun­dance and dis­tri­bu­tion in the state.

“Fowler’s toads and mink frogs have a lim­ited range in Michi­gan, un­like most other species that oc­cur statewide,” said Lori Sar­gent, the DNR’S frog and toad sur­vey co­or­di­na­tor. “Over the past 20 years, through an­a­lyz­ing the sur­vey data col­lected, we’ve no­ticed a de­cline in these two species in Michi­gan.”

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.

Sar­gent said new vol­un­teers are needed in all parts of the state, and the con­tin­ued suc­cess of the sur­vey is de­pen­dent on strong vol­un­teer sup­port. Those in­ter­ested in vol­un­teer­ing should con­tact Lori Sar­gent at (517) 284-6216 or sar­[email protected]­gan.gov.
