Lyme – The Lyme Land Trust will sponsor an open air seminar and beaver walk at 10 a.m. Oct. 6.

The guided walk will visit three sites of beaver activity to show the ecological cycle of beaver activity that changes the landscape, invigorates biological diversity, and triggers recurring cycles of animal and plant habitat development.

Ann Kilpatrick, district wildlife biologist with the state Department of Energy & Environmental Protection, will be the guide and seminar leader. She will explain how the beavers create habitat for many other species of both plants and animals in the course of building their own watery homes.

This moderately rugged two-mile walk will be primarily along forest trails and will take between two and three hours. Sturdy, waterproof shoes are recommended. Admission is free; children are welcome. Participants should not bring pets.

The walk will start at Clucas Field on Brush Hill Road, about a quarter mile west of Tantumorantum Road.
