LEWISTON — The Maine Master Naturalist Program is accepting applications for its 2012-13 year course taking place at Bates College, in partnership with the Stanton Bird Club and the Androscoggin Land Trust.

The training, which includes 10 Wednesday evening classes and five Saturday field trips, costs $300.

Upon enrollment, participants agree to give 40 hours of service to conservation nonprofits or schools during the year following certification, and they must continue to volunteer to remain active Maine Master Naturalists.

The organization’s goal is to develop a statewide network of volunteers to teach Maine natural history at parks, conservation organizations and schools throughout Maine.

“The Lewiston course will provide participants with over 60 hours of classroom and field experience focusing on ecological principles, wetland and upland ecology, identification of Maine’s flora and fauna, geology, soil science and teaching skills,” said Susan Hayward, course coordinator and faculty member.

She said, “By the end of the program, participants will have developed the skills to lead an informative walk, present talks and slide shows, provide outreach to children in schools or on land trust/park property, and teach people how to identify common trees, wildflowers, birds and other plants and animals.”
