Vascular Plant Species List for Web.Docx

Vascular Plant Species List Cedar River Municipal Watershed

This vascular plant species list for the Cedar River Municipal Watershed (CRMW) was compiled from a series of botanical forays conducted in association with the University of Washington Burke Museum Herbarium, surveys for invasive plant species, several monitoring and research projects, and observations by CRMW biological staff during the course of their field work, 2001-2012.

In the column "Species ID confidence", a "High" was given to specimens vouchered in the Burke Museum Herbarium, specimens collected and identified with high confidence by an experienced botanist but not vouchered, and species that are commonly known and could not be confused with any other species. All other species were given a "Good" confidence level. Only species that were collected and identified with at least good confidence by an experienced botanist are included in the list.

Nomenclature is according to the USDA Natural Resources Conservation Service PLANTS Database (http://plants.usda.gov/java/). Where specimens were vouchered under a different name, the vouchered synonym is provided.
