Ecologist Aram Calhoun will lead a vernal pool walk on Sears Island Wednesday, May 9, from 10 a.m. to noon.

Program participants will learn about vernal pool fauna and the landscape-scale functions of vernal pools. If time allows, Calhoun will also show the group some mitigation pools on Sears Island where she conducted research tracking populations of wood frogs and spotted salamanders.

Aram JK Calhoun is a professor of wetland ecology in the Department of Wildlife, Fisheries, and Conservation Biology at the University of Maine. Her research focuses on conservation of forested wetlands and vernal pool ecosystems. She is particularly interested in conservation of natural resources on private lands and collaborative approaches to conserving wetlands through locally driven initiatives.

Dr. Calhoun is active in working at all levels of government on wetland policy and conservation issues. She will be joined by Dr. Kristine Hoffmann, who is a herpetologist and blue spotted salamander expert.
