P. MARK S. ASHTON is Associate Professor of Silviculture in the Yale School of Forestry and Environmental Studies where he has been since receiving his doctorate there in 1991. He also has a M.F. degree from Yale and a B.S. (high honors) from the University of Maine (Orono) College of Forest Resources. His current research is in tree seedling physiological ecology, adaptation of leaves to their environment, disturbance and landscape level dynamics of forests, plantation analogs of mixed-species stands, restoration of degraded forest lands, and silviculture of non-timber forest crops. He has served as manager of the Yale-Myers Forest in Connecticut, and worked as a full-time forestry and natural resources consultant. He has extensive overseas experience, particularly in South and Southeast Asia, and works with Mistik Management in Saskatchewan. In addition to English, he speaks French and Sinhala, and some Malay.
