The high alpine summits of New England, New York, and eastern Canada contribute significantly to the plant, bird, and invertebrate diversity of northeastern North America. Well-known summits such as Mount Washington have been the focus of ecological inquiry since the early 1800s. Beyond the Presidential Range and such other well-known mountains as Katahdin, Mont Jacques-Cartier, and Gros Morne are many little-known eastern alpine mountain ranges, unified by the treeless alpine communities on their slopes and summits but facing their own unique conservation challenges. Join New England Wild Flower Society on Wednesday, February 25 from 7 – 8:30 at Garden in the Woods for a presentation and lecture on the natural history of the lesser-known alpine ecosystems of Québec, Labrador, and Newfoundland and for a book signing by Liz Willey and Mike Jones, editors of the Eastern Alpine Guide: Natural History and Conservation of Mountain Tundra East of the Rockies and co-founders of Beyond Ktaadn (beyondktaadn.org). $13 for NEWFS members, $15 for nonmembers.  Register online at http://www.newenglandwild.org/learn/our-programs/amazing-alpine-communities-of-the-northeast.
