Abstract:
part of the Willamette Basin Geographic Initiative Program, the Environmental Protection Agency (EPA) funded The Nature Conservancy of Oregon to inventory, classify, and map native wetland and riparian plant communities and their threatened biota in the Willamette Valley. Between October 1994 and September 1996, we evaluated 172 wetland and riparian sites throughout the Willamette Valley. A site is a stream or river reach or wetland area that was inventoried at one to many locations. Of these sites, 21 are high-quality remnants important for future protection and restoration efforts. We identified 153 natural communities as occurring in native wetland and riparian habitats, of which 101 are new to the plant community classification of the Oregon Natural Heritage Program.
Purpose:
This project was conducted in order to gather information about the Willamette Valley to aid in the development of the Willamette Valley Conservation Plan. The Willamette Valley represents one of the most threatened ecoregions in Oregon. This Phase I Project is a much needed project that has the potential to promote integrated efforts on a wide range of activities in the basin that have at their core the conservation of aquatic and terrestrial related natural resources. The Willamette Valley was dominated by extensive and diverse riparian and wetland plant communities during presettlement times in the early 1800's (Johannessen et al. 1971). Settlement of the Willamette Valley, the endpoint of the Oregon Trail, brought dramatic changes to the landscape as it was cleared for pasture and drained for agricultural purposes (Boag 1992). Now only about 10% of the Willamette Valley remains in relatively natural vegetative communities. The Willamette Valley also became home to over two-thirds of the state’s population by the end of the 1980's. Finally, the streams and rivers which drained into the Willamette Valley have changed significantly since presettlement times, with flood control dams and stream channelization projects resulting in a vastly different hydrologic regime than previously existed for the Willamette drainage (Seddell and Froggatt, 1984). Nevertheless, in the face of extensive alteration of natural habitats, there remain examples of natural communities and populations of rare and threatened species. These occurrences, and the open spaces of the valley, are prime attractions to the human population there who desire increased connection to the outdoors for recreation and renewal. Maintaining biodiversity and restoring sites critical for conservation is as necessary for the long-term livability of the Willamette Valley as it is for the long-term survival of the species native to the ecoregion.
