Wilderness Landscape & Natural Heritage
The Bull Run Watershed Management Unit, located in Oregon, is a vital area that supplies Portland with its primary water source. Encompassing approximately 102,000 acres, this watershed is characterized by dense forests and rugged terrain, consisting of a combination of coniferous trees like Douglas fir and western hemlock. The area is strictly protected to maintain water quality, prohibiting public access to preserve its pristine condition. Historically, it has been managed for water production since the late 19th century, reflecting early conservation efforts. While it is not open for recreation due to its primary role as a water source, the surrounding Mount Hood National Forest offers numerous recreational opportunities. Conservation in this region is critical, both for maintaining Portland's drinking water supply and for safeguarding its unique ecosystem.
