David Gilligan

David Gilligan, author The Secret Sierra, The Alpine World Above the Trees, has made the natural history of the Alpine Sierra Nevada his life’s study. A graduate of Prescott College in natural history and ecology, where he now lectures, David has worked with several organizations as teacher and naturalist, focusing on programs and curriculum in forest, stream and intertidal ecology, environmental awareness, nature philosophy, and natural history. He has traveled extensively through the Sierra Nevada backcountry on trips of a hundred days in length by foot, ski, and snowshoe. Integrating his skills as an observer with his education as a scientist, he has studied and practiced primitive and pioneer skills such as fire making, shelter building, edible and medicinal uses of wild plants and animals. When David is not teaching natural history, ecology, and landscape geography, he is in the field studying the alpine zone of the Sierra Nevada.
