Members of the Site Assessment Team completing the site assessment at a wetland mitigation site in Snohomish County. |
 |
The Phase 2 study found a net gain of open water and aquatic bed as a result of mitigation activities. |
 |
An Eastern Washington created wetland that provided a high contribution to water quality and wildlife habitat. |
 |
One of the few restoration sites evaluated in the Phase 2 study. |
 |
This enhanced wetland was minimally successful. This project met permit requirements by enhancing vegetation structure, but it did not provide a sufficient contribution to compensate for the wetlands lost. |
 |
The mitigation actions on this site failed to enhance any wetland functions. |
 |
Surrounding land uses influence the success of mitigation projects. Proximity to high density residential areas can decrease the wetland’s ability to provide habitat functions. |
 |
Is it a wetland? The Site Assessment Team used the WA State Wetland Delineation Manual to determine wetland boundaries. Presence of hydric soils is one of the necessary components. |
 |
Skunk cabbage (Lysichitum americanum) was present along with other native wetland species at this created wetland in King County, which was moderately successful. |
