Functions Characterization / Assessment: What do the wetlands do?
A wetland biologist may perform an assessment to determine and describe what functions the wetland provides, using one of the assessment tools below. • Wetland Functions Characterization Tool for Linear Projects (pdf 119 Kb) Also known as the Wetland Functions Best Professional Judgment (BPJ) Tool, Washington State Department of Transportation developed this method in 2000. WSDOT biologists routinely apply this method to all wetlands occurring within project right-of-ways and project areas. • Summary of Functions and Values Form (doc 32 Kb) (Use this form to summarize wetland functions for the BPJ Tool.) • Washington State Wetland Function Assessment Method Also known as WFAM, the Washington Department of Ecology developed this method in 1991. Because WFAM is so time consuming to perform, this method is only used when specifically required by regulatory agencies. WSDOT wetland biologists have utilized this method on their wetland mitigation bank sites. (top of page) Wetland Rating: How
