FORESTS IN TIME: THE ENVIRONMENTAL CONSEQUENCES OF 1,000 YEARS OF CHANGE IN NEW ENGLAND

Edited by David R. Foster and John D. Aber. P.O. Box 209040, New Haven, Connecticut 06520-9040: Yale University Press, March 2004. (203) 432-0964. www.yalebooks.com. ISBN 0-300-09235-0. 496 pp. $45.00 Clothbound.

Leading biological, physical, and social scientists contributed to Forests in Time--a book demonstrating that an understanding of landscape history is essential for the study of ecology and environmental management. The research that forms the basis of the book was conducted in central Massachusetts at Harvard Forest--one of 25 national centers for ecological research funded by the National Science Foundation.

Although New England is one of the most heavily forested regions of the United States today, this was not always the case. The authors examine how 1,000 years of both natural and man-made influences have affected the ecosystem. They analyze the legacy of land use embedded in the stone walls, empty cellar holes, wood paths, and abandoned railroad beds throughout the region; they draw upon clues in the soils, streams, ponds, and forests to discover previous land use practices through time and show how land use has affected vegetation, wildlife, and ecosystem structures.
