“When I consider the melancholy fate of so many of botany's votaries, I am tempted to ask whether men are in their right mind who so desperately risk life and everything else through the love of ‘collecting' plants.”

-Carolus Linnaeus, "Glory of the Scientist," 1737

David Douglas, a Naturalist at Work: An Illustrated Exploration Across Two Centuries in the Pacific Northwest, a book by Jack Nisbet, is a colorfully illustrated collection of essays that examines various aspects of Douglas's career, demonstrating the connections between his work in the Pacific Northwest of the 19th century and the place we know today. From the Columbia River's perilous bar to luminous blooms of mountain wildflowers; from ever-changing frontiers of technology to the quiet seasonal rhythms of tribal families gathering roots, these essays collapse time to shed light on people and landscapes. 

Finding David Douglasa documentary film follows the short life of David Douglas as he explored western North America in a time before white settlement altered the landscape. He discovered and introduced more than 200 new species to the gardens and forests of Europe. This film was produced by the Oregon Cultural Heritage Commission in collaboration with the US Forest Service and Forestry Commission Scotland.
