The Northern Forest Region lies between the oak forests of the eastern United States and the boreal forests of eastern Canada. It is, collectively, one of the largest and most continuous temperate forests left in the world and, like much of the biosphere, it is at risk. This guide is an essential companion for those interested in stewardship and conservation of the region. Through multi-image composite photos that allow for unparalleled depth and clarity, this unique guide illustrates the majority of the 265 species of woody plants present in the forest and its associated communities. With a visual glossary, nineteen quick guides, and five systematic sections, this book is intended as a quick reference for the rapid identification of twigs and leaves. It is an invaluable tool for foresters and an excellent teaching guide for all ages.
