This project report provides a GIS map to accompany the 1999 tidal wetland prioritization in these estuaries. updates information on major changes at 1999 study sites, and recommends revisions to the NWI wetland classification for tidal wetlands. Study included emergent, scrub-shrub and forested tidal wetlands but excluded other tidal wetland habitat classes.

Abstract or Summary
  • Green Point Consulting created a GIS layer of current and likely former tidal wetlands in the Yaquina and Alsea estuaries, working from the National Wetland Inventory (NWI) mapping and applied their field knowledge of the estuaries, as well as newly available data such as LiDAR and recent aerial orthophotos. They identified all NWI polygons that corresponded to the study sites in our 1999 tidal wetland prioritization. (Brophy 1999. Final Report: Yaquina and Alsea River Basins Estuarine Wetland Site Prioritization Project) they also reviewed the NWI wetland classification for these areas, and recommended revisions. They identified substantial areas of likely former tidal wetlands that are classified as upland in the NWI, but did not recommended a wetland classification to these areas, since the project’s scope of work did not allow us to determine their current wetland status. The results provide considerable new data for estuarine resource management in these two estuaries.
