Academics at Prescott College

Tom Fleischner, Ph.D.

Faculty Emeritus

Tom's work is always rooted in natural history, ecology, and conservation biology, but plies the terrain at the margins of disciplines. He's most interested in the connections between sciences, humanities, and public policy, and between analytical and creative modes of thought.  After 29 years at the college, Tom is now Faculty Emeritus, as well as the Executive Director of the Natural History Institute.  From both these vantage points, he will continue to work with Prescott College classes and students. In addition to helping to coordinate the Conservation Biology and Natural History and Ecology emphasis areas within the undergraduate Environmental Studies curriculum, Tom has taught courses that link with many other curricular areas, including creative writing, environmental politics, and ecopsychology.  

"Natural history is the process of falling in love with the world."

Tom Fleischner



Ph.D., Environmental Studies. The Union Institute, 1998.
M.S., Biology. Western Washington University, 1983.
B.S., Field Biology. The Evergreen State College, 1977.



Tom has written two books—Singing Stone: A Natural History of the Escalante Canyons and Desert Wetlands, and edited two more-- The Way of Natural History, and the upcoming Nature, Love, Medicine: Essays On Healing In Wildness—as well as numerous journal articles and book chapters. (The Way of Natural History was included in the "Best of Science" short list in the Wall Street Journal, and also was awarded Honorable Mention in the ForeWord Book of the Year Awards.)  He co-founded the North Cascades Institute in Washington State, and served on the Board of Governors of the Society for Conservation Biology, the Science Advisory Council of the Grand Canyon Trust, and served in an advisory capacity to many other local and regional organizations. He was a long-term member of the Education Committee of the Society for Conservation Biology, and served as President of the society’s Colorado Plateau Chapter.  

Field research projects include an ongoing study of migratory and wintering shorebirds at Estero Santa Cruz in the Gulf of California, Mexico.  For many years Tom was involved in studying the ecological effects of livestock grazing in western North America.  He chaired the committee that wrote a position statement on this topic for the Society for Conservation Biology.   Earlier field research concerned marine mammals and marine birds. Recently, he has written and spoken extensively on the critical importance of natural history and field studies.  As part of these efforts, he has been a principal investigator on two National Science Foundation grants in the last six years.
