First published in 1990, Forests explores the ecological, economic, and human influences on over thirty significant types of woodlands. Laurence Walker focuses especially on the effects of site factors—climate, physiography, biology, and soils—upon the growth of various kinds of trees. Projects for amateur naturalists, reading lists, and a glossary make this the perfect introduction for general readers.
The late Laurence C. Walker enjoyed a fifty-year career in forest management, research, and instruction.
