My work is always rooted in natural history, ecology, and conservation biology, but plies the terrain at the margins of disciplines. I’m most interested in the connections between sciences, humanities, and public policy, and between analytical and creative modes of thought.  I'm fascinated by the confluence of nature & culture, biology & adaptation, when considering humans as an ecological species.

I have taught in the interdisciplinary Environmental Studies Program at Prescott College for 29 years.  In addition to helping coordinate the Conservation Biology and Natural History and Ecology emphasis areas, I teach courses that link with many other curricular areas, including creative writing, environmental politics, and ecopsychology (see Teaching).  I'm also founding Director of the college's Natural History Institute, which seeks to integrate art, science, and humanities in the work of connecting humans and nature.  

Much of my work over the past few years has focused on revitalizing the practice of natural history (see Natural History Projects). Here's the most recent of many writings on this topic (others available here, at bottom of page). I was the founding President of the Natural History Network.

I've been delighted and honored to lead a National Science Foundation project, The Decline in Field Studies: Proactive Strategies for Essential Training for the Next Generation of Biological Researchers,” to address the growing crisis in American (and, indeed, global) ecological sciences training--that fewer and fewer students have the opportunity to study and learn in the field, directly from nature.  We convened a working group of  faculty, administrators, and practitioners from across the spectrum of field education to identify the specific obstacles that have made field study increasingly difficult in some institutions--and defined and communicated specific strategies to remove these obstacles.  An article we wrote on this topic, "Teaching Biology in the Field: Importance, Challenges, and Solutions," has recently been accepted by the professional journal, BioScience.

Recent 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 I've been involved in studying the ecological effects of livestock grazing in western North America.  I chaired the committee that wrote a position statement on this topic for the Society for Conservation Biology.  More recently, colleagues and I conducted a study of the ecological effects of historic livestock grazing on plant communities in Chaco Canyon, New Mexico (as well as a follow-up study).  I wrote earlier and more recent synthesis papers on livestock grazing and wildilfe conservation in the American West.  Recently, I was a co-author on a paper linking livestock and native ungulates to climate change concerns; this paper received a great deal of response, both positive and negative.  We wrote a follow-up paper that responds to one of the latter.

Earlier field research concerned marine mammals and marine birds.  I continue to be fascinated with these animals; they remain strong passions, and subjects in my teaching (including in a recent field program on island biogeography in the Gulf of California, one of my favorite places in the world). I have written two books—Singing Stone: A Natural History of the Escalante Canyons and Desert Wetlandsand edited a third,  The Way of Natural History.  This anthology received attention from reviewers as diverse as the Wall Street Journal, which included Way on its end of year "Best of Science" list, and the Shambhala Sun.   It received an Honorable Mention in the ForeWord Book of the Year Awards. I've also written numerous journal articles and book chapters (see Publications).

I've recently finished editing another anthology,  Nature, Love, Medicine: Essays on Healing in Wildnesswhich will be published later this year by Torrey House Press.  The book gathers narrative essays that address three interrelated questions: "How can nature heal us, as individuals and communities?," "How does practicing natural history lead to healthier lives?," and "Why does deep engagement with nature help us love the world?"

I co-founded the North Cascades Institute in Washington State, and have served on the Board of Governors of the Society for Conservation Biology, the Science Advisory Council of the Grand Canyon Trust, and many other local and regional organizations. I 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.
