Note: These trees were the first source of major gene resistance in western white pine. Jerry Barnes was the first Project Leader at Dorena (1966-1977). The last of the western white pine trees at this location dies of blister rust (from a virulent strain) by 1994.

Dorena Genetic Resource Center (DGRC) is the USDA Forest Service's regional service center for genetics in the Pacific Northwest Region. Dorena houses disease resistance breeding programs for five-needled pines and Port-Orford-cedar, a native plant development program, and the National Tree Climbing Program.
