The Willow Creek site is one of the most significant remaining areas of typical native Willamette Valley habitats, with a variety of wetlands, grasslands, and woodlands. A diverse array of native flora and fauna, with significant wildlife habitats, is present on the site. Wildlife diversity is high, and includes species of mammals, songbirds, raptors, reptiles, amphibians, and one rare invertebrate. Over 200 species of native plants have been identified (including populations of six rare, threatened, or endangered species), along with significant remnants of native plant communities. Willow Creek is located in Lane County, Oregon, on the western edge of the City of Eugene (see Figure 1). The city limit of Eugene passes through the site, and the site is entirely within the Eugene Urban Growth Boundary (UGB). At present, only lands to the east and northeast of the site are developed to full urban densities. Low density rural residential and agricultural land uses predominate on lands to the northwest and south. A partially completed light industrial/research office park is located to the northwest. Several informal trails lead south from West 18th at various points into the site. The area encompasses a total of approximately 349 acres under several ownerships, in …

"The purpose of this profile is to summarize the ecological information available for and relevant to stream and riparian habitats of the Great Basin. The Great Basin comprises the northern half of the Basin and Range physiographic province and covers most of Nevada and western Utah and portions of California, Oregon, and Idaho. The entire basin actually consists of numerous subbasins and mountain ranges which present an extremely diverse physical setting" (p. iii).
