Trees in Your Pocket: A Guide to Trees of the Upper Midwest

Valued for their lumber, their shade, and the beauty of their flowers and foliage as well as the nuts that nourish wildlife and humans alike, trees play important economic, ecological, and aesthetic roles in our lives. From honey and black locusts to white and chinkapin oaks to yellow and river birches, Trees in Your Pocket gives us identification and natural history information for about forty prominent deciduous species found in the Upper Midwest states of Minnesota, Wisconsin, Illinois, Iowa, and Missouri.

 

Botanist Tom Rosburg provides diagnostic color photographs of leaves, acorns and other fruits, and bark along with descriptions of leaves, fruits, and measurements of blades. The composition, arrangement, shape, and margin of leaves are most important for tree identification. Fruits can help confirm identification of species with similar leaves. The bark of a tree can be very helpful for identifying some species; as a tree ages, older bark (lower on the tree) can be quite different from younger bark (higher and on branches). In addition to these essential markers, Rosburg gives information about the range, habitat—savannas, moist forests, dry slopes, sandy soils, and so on—life-span, and tolerance of shade, fire, drought, and flood.
