Current wetland datasets in Oregon • NWI – wetlands • NRCS -- hydric soils • NHD -- waterbodies and springs • OSU -- vegetation and conservation • TWC -- conservation • OWEB -- wetland restoration projects (OWRI) • ODFW -- Conservation Opp Areas from WCS • DSL – fill & removal, mitigation, LWIs, delineations • USFS, BLM, USFWS, OPRD: wetlands, vegetation, condition

  5. Local Wetland Inventories (LWIs) Miscellaneous wetland mapping Agencies, NGOs Theses, reports Plot data Wetland delineations “Enhanced NWI”

  6. LWIs (Corvallis) Blue = NWI, Red = LWI Available data: Cowardin HGM Veg Condition Conservation Status
