Site History and Existing Conditions
Mariposa Woodland is located within the City of Eugene (City) owned Spencer Butte Park. Totaling 29.5 acres, the site extends from the parking area at 52nd Avenue and Willamette Street along a narrow corridor, following a well defined ridgeline to the lower north slope of Spencer Butte. In addition to accommodating a key segment of the existing Ridgeline Trail, this site contains an area of unique habitat including areas of oak-pine woodland, savanna, and prairie. These habitat types have declined significantly in the Willamette Valley over the past century and are vulnerable to at this site as well without significant management intervention. This oak-pine woodland includes numerous large ancient Willamette Valley ponderosa pine, Oregon white oak, and California black oak as well as a high quality under story with a diversity of native grasses and forbs. The City has identified this particular area for immediate habitat enhancement and management due to the high quality and diversity of the existing habitat and the likelihood of significant decline in quality if no management actions are taken.
