Did you know there are no earthworms native to the Great Lakes? And did you know that they are destroying some of our forests? Earthworms of the Great Lakes will not only help you identify 16 species that are found in the ground beneath your feet, but it will also educate you as to their role in our forest ecosystems. This book is an excellent classroom research tool. Methods for collecting worms and keys to identifying your finds are included.
