Summary
Shrubs are an important component of terrestrial plant communities in both forested and nonforested ecosystems, but relatively little information is available on their distributions. This project provides mapped occurrences for 78 native shrub species found in the Pacific Northwest (Oregon, Washington, Idaho, and western Montana) as derived from two large regional databases: the U.S. Department of Agriculture, Forest Service Forest Inventory and Analysis database of vegetation collected as part of a nationwide forest inventory and the Consortium of Pacific Northwest Herbaria online database (http://www.pnwherbaria.org) of species locations from forested and nonforested habitats. Background information on the project and maps of locations by species and data source are included.
