The Great Lakes Basin is a fertile ground for nature exploration and learning. Covering a staggering 94,000 square miles, it is the world’s largest freshwater watershed. It spans rich hardwood forests at its southern edge, boreal forests at its north end, and mixed-wood plains in between. There are also coastal dune systems, the largest freshwater island in the world (Manitoulin Island), prairie remnants, and numerous mighty rivers. Over 450 birds annually occur here, and thousands of plants grow across the various landscapes. Learning about the many life forms is a tall order, so it helps to have a starting point like the portable reference guides Great Lakes Birds, Great Lakes Trees and Wildflowers, and Great Lakes Wildlife, each of which is beautifully illustrated with 140 common and familiar species and includes an ecoregion map showing nature hotspots and learning sites. Laminated for durability, these 12-panel folding pocket guides are offered in the three-pack Great Lakes Nature Set and collectively serve as means to identify representative species and peer into their fascinating lives.
