Service Description: Version 20091030 (October 30, 2009). The Oregon Wetlands Cover is a compilation of polygon data from numerous sources, and represents the most comprehensive dataset available for the location and composition of the state's wetlands. It uses as a base all available digital data from the National Wetland Inventory (NWI; U.S. Fish and Wildlife Service, USFWS), to which has been added draft NWI mapping (Oregon Natural Heritage Information Center and The Wetlands Conservancy, ORNHIC and TWC), mapping from Local Wetland Inventories (LWIs; Department of State Lands, DSL), wetlands along state highways (Oregon Department of Transportation, ODOT), and mapping of individual sites by a variety of federal, state, academic, and nonprofit sources. Because the Oregon Wetlands Cover is based on the NWI framework, it represents all wetland categories in the Cowardin classification (Cowardin, L.M., V. Carter, F.C. Golet & E.T. LaRoe. 1979. Classification of wetlands and deepwater habitats of the United States. USDI Fish & Wildlfe Service, Biological Services Program. FWS/OBS-79/31. 103 pp. ; ) that are known to be present and mappable in Oregon. It includes perennially inundated "open water" aquatic habitats such as lacustrine limnetic, riverine (all subsystems), and marine and estuarine intertidal and subtidal. Man-made water features such as industrial detention ponds, log ponds, municipal sewage treatment lagoons, and flooded gravel pits are also included because they are often habitat for wetland biota. Portions of upland riparian areas may also be included where they are intermixed with riverine or palustrine wetlands and cannot be separated at the scale used in original mapping. Despite the inclusion of wetland spatial data from many different sources, a multitude of wetlands in Oregon have yet to be identified and mapped, and are not present in this coverage. This is especially true for seasonal, small, farmed, and forested wetlands that are difficult to detect with aerial photography.
