FALMOUTH — The Maine Audubon is seeking volunteers to survey roads in the western part of the state for signs of wildlife crossings.

Officials say data collected by volunteers about where, when and how many animals cross roads is the first step in identifying ways to reduce wildlife road mortality.

Maine Audubon is looking for volunteers to survey sections of Routes 4, 16, 27 and 201. Doug Hitchcox, Maine Audubon staff naturalist, says the goal is to find areas of concentration of wildlife movement.

Since the program’s inception in 2010, more than 460 volunteers have reported more than 3,600 wildlife observations. Those include reports of rare and endangered species.
