Have you ever wondered what a plant was, and why it grows there? John Kotar can tell you! As emeritus professor of forest ecology from University of Wisconsin-Madison, Kotar developed an ecological classification system for Great Lakes forests. Join him on a field trip to a local trail to talk about how geology, soils, climate, natural disturbances, and the history of land use interact in creating a rich variety of forest types and distinct and predictable patterns of their distribution on the landscape. Call ahead to find out where to meet. 10:00 a.m.-2:00 p.m. Bring a lunch and water; dress for the weather. Expect a short walk with many pauses for questions and answers. Register by August 25 by calling the Cable Natural History Museum 715-798-3890. $10 member/$15 non-member.
