The Wetlands Inventory and Survey Maps document the National Wetlands Inventory as conducted in the western United States and the central Willamette Valley and Pacific Coast in Oregon by the U.S. Fish and Wildlife Service, Office of Biological Services. The collection includes an atlas of state and local wetlands surveys that had been conducted in 1965-1975 as well as drafts of wetlands inventory maps documenting the type and extent of coastal and inland wetlands in Oregon.

The Wetlands Inventory and Survey Maps document the National Wetlands Inventory as conducted in the western United States and the central Willamette Valley and Pacific Coast in Oregon. The collection includes two atlases. One atlas depicts the extent of state and local wetlands surveys that had been conducted in 1965-1975. The second atlas shows the types and coverage of aerial photography available for conducting wetlands surveys and inventories. Drafts of wetlands inventory maps for the area from the central Willamette Valley to the coast comprise about half of the collection. These maps document the type and extent of coastal and inland wetlands following the Cowardin Classification System developed by the U.S. Fish and Wildlife Service in 1979. The Cowardin system is a hierarchical classification consisting of the major wetlands classes of marine, estuarine, riverine, lacustrine, and palustrine. Details on water flow, substrate, vegetation, flooding, and salinity define subclassifications within the major classes. The maps were prepared primarily by stereoscopic analysis of high-altitude aerial photographs; wetlands were identified based on vegetation, visible hydrology, and geography. Selected sites were examined in the field. All of the maps are blueline prints.

More Extent Information: 36 maps; 2 map folders

Statement on Access: Collection is open for research.

Acquisition Note: These materials were transferred from the Oregon State University Libraries' maps collection to the Special Collections & Archives Research Center in 2014.

Related Materials: Final National Wetlands Inventory maps for portions of the Willamette Valley and the Oregon Coast are available in the Valley Library maps collections and in the Guin Library at the Hatfield Marine Science Center. The Planimetric Maps of Oregon and Washington (MAPS Planimetric), Environmental Remote Sensing Applications Laboratory Records (RG 218), and Sea Grant College Program Records (RG 201) include additional materials regarding wetlands in Oregon.
