Naturalists and authors Tony Oppersdorff of Lincolnville and Kyrill Schabert of Jefferson will speak Wednesday, June 5, at 7 p.m. at the Lincolnville Community Library, at the corner of Main Street/Route 173 and Heal Road in Lincolnville Center.

Oppersdorff and Schabert are the authors of “Best Nature Sites: Midcoast Maine,” a natural history guide to sites along the Route 1 corridor from Brunswick to Belfast. The book includes beautiful color photos on nearly every page plus drawings, maps and facts about flora and fauna and historical features of particular sites.

The authors chose 40 sites along Route 1 that reflect a compromise of accessibility, diversity, interest and reward. Their guide offers fascinating information about everything from how chickadees survive the Maine winter to the many uses of cattails. It also tells about historical sites such as the Whaleback Shell Midden in Damariscotta; a stone circular cattle pound in Jefferson; and a German cemetery in Waldoboro. Oppersdorff did much of the writing for the guide, which also includes contributions from local naturalists, conservationists and specialists in geology, ornithology and plant and animal biology. Local land trusts and conservation organizations also provided help and information.

There will be refreshments and plenty of time for discussion following the talk. For more information, email fireweed@tidewater.net.
