Specimen Records: 76,663
Media Records: 26,245
iDigBio Last Ingested Date: 2026-02-19

The herbarium's total holdings number over 600,000 specimens of vascular and nonvascular plants, fungi, lichens, and marine algae. The herbarium maintains a regional focus on the Pacific Northwest, covering Washington, Oregon, Idaho, Montana, Alaska, British Columbia, and the Yukon Territory. Other significant collections come from California, the rest of Western North America, and the Pacific Rim. Our oldest specimens date to the late 1800's. Particularly active periods of growth for the herbarium occurred with the incorporation of the herbarium of J. William Thompson in 1943, collections made under the direction of C. Leo Hitchcock in the 1930's - 1950's, and field work since 2002.
