Trees and Shrubs for the Northern Plains

While there are many excellent publications written about the plant world, there has been no book available which deals specifically with the trees and shrubs of the Northern Great Plains. This is why it is particularly noteworthy that Mr. Donald G. Hoag, the author, has so painstakingly and successfully brought together the scholarly information presented in this book. This information can be as readily used by the amateur who enjoys planting a few trees and shrubs around the house as by the botanist who wants and needs exact and specific technical information. Another feature of this book is the illustrated winter key. Most keys for plant identification are summer keys depending upon fruit, flowers and leaves for identifying features. A reliable key makes plant material readily identifiable at any time of the year. The summer key also makes use of features evident all the year.
