This curriculum is made possible by a grant from the Maine Outdoor Heritage Fund (www.mohf.org), and by generous support of the Margaret E. Burnham Charitable Trust. Karen Hoydick Rent and Cathy Stivers both helped develop the classroom activities and the Maine Learning Results matrix. Thanks to Dave Evers, Kate Taylor, Lee Attix and Nina Schoch (all at BioDiversity Research Institute, www.briloon.org) for their detailed comments on the text, and to Lisa Kane at the Maine Department of Inland Fisheries and Wildlife for her comments and support. Thanks to volunteer Shirley Wells, and Maine Audubon staff Becca Wilson and Bob Bittenbender for all their help, especially in pulling together the final edits and the supplemental boxes. A special thanks to the many amateur photographers who gave us permission to use their photos throughout the curriculum.
