Dr. David Haskell, professor of biology at the University of the South and author of the acclaimed “The Forest Unseen: A Year’s Watch in Nature” will talk about his book this Tuesday, Oct. 16 at 6:30 p.m., at Highland Rim Music and Art, 108 W. Main Street.In his wholly original book, Haskell uses a one-square-meter patch of old-growth Tennessee forest as a window into the entire natural world. Visiting it almost daily for one year to trace nature’s path through the seasons, he brings the forest and its inhabitants to vivid life. “The Forest Unseen” has received outstanding reviews from many sources, including the Atlanta Journal Constitution: “Under Haskell’s magnifying glass, what to us looks like an unremarkable forest floor takes on the exquisite, layered intricacy of a Faberge egg, its color and texture more vivid than photographs …” Haskell’s classes at the University of the South have received national attention for the innovative ways in which they combine scientific exploration, contemplative practice and action in the community.
