Abstract
  • This project defined criteria to allow only the use of existing spatial databases (and only those with comprehensive coverage of the ecoregion) to identify the HGM (hydrogeomorphic) class of mapped Willamette Ecoregion wetlands. The project then applied those criteria automatically and systematically to every mapped wetland in the ecoregion, resulting in an HGM label for each mapped wetland. The project also created a database that describes over 200 attributes of each mapped wetland in the Willamette ecoregion, i.e., a regional wetland “profile.”
