FALMOUTH, Maine — Maine’s largest conservation organization is undergoing a reorganization that will include layoffs as it seeks ways to make do during the economic downturn.

Maine Audubon announced Tuesday that 12 jobs will be eliminated by September from its pool of 60 full-time, part-time and seasonal positions.

Maine Audubon’s trustees have been analyzing the organization’s operating costs, fundraising projections and revenue-generating programs.

The Falmouth-based organization says it will focus on its core environmental education, conservation and advocacy projects as well as keeping its wildlife sanctuaries open to the public.
