Blue Ridge Berryessa Natural Area, Protected natural area in northern California, United States

Blue Ridge Berryessa Natural Area is a protected area in northern California that covers a mix of open grassland, oak woodland, ridgelines, and the shores of Lake Berryessa. Several creeks run through the land, draining into the Sacramento River watershed to the north.

The Blue Ridge Berryessa Natural Area Conservation Partnership was founded in 1997 as a forum for land managers to discuss land use, primarily Homestake Mining Company surplus acreage at McLaughlin mine. The meetings evolved into a regional conservation effort. In 2002 the Partnership received the California Governor's Environmental and Economic Leadership Award in Watershed Management.

The name joins the Blue Ridge Mountains and Lake Berryessa, the two features the corridor links. The partnership counts over 100 participants, among them Yolo Land & Cattle Co., Guenoc Ranch and Winery, Gamble Ranch, the Bureau of Land Management and the University of California Natural Reserve System. In 2002 it received the California Governor's Environmental and Economic Leadership Award for watershed management.

The parking area near Monticello Dam, close to Napa, is the main starting point for most trails in the area. Trail surfaces can become very dry and hard in summer or muddy after rain, so it helps to check conditions before heading out.

The area sits at the meeting point of two of California's major plant zones, which means desert shrubs and cool-climate oaks grow side by side within a short walking distance. This overlap draws a wide range of birds and mammals that are not typically found together in one place.
