Join David Douglas on a nature walk as he guides you through the flora and fauna of the Northwest.

David Douglas was a Scottish-British botanist who traveled through North America, collecting and documenting the botanical life of the Oregon Territory. Oregon's state tree, the Douglas Fir, is named after him.

Douglas came to the U.S. as a botanical collector for the Royal Horticultural Society, making his trip in 1823; he later made several other scientific journeys, returning to the North American Far West frequently. He introduced roughly 50 new trees and shrubs and about 100 herbaceous plants into England during his career.
