Canada de los Osos Ecological Reserve Updated:06/2019


This approximately 5,800-acre property has a mix of annual grasslands, oak and montane woodland, chaparral, riparian and wetland habitats, with numerous springs and ponds. Raptors, including golden eagles, nest throughout the region and wintering bald eagles are occasionally seen. Several bat species use the area throughout the year. Other wildlife species found on the property include mountain lions, black-tailed deer, wild pigs, wild turkeys, California quail, and Neotropical migrant songbirds.

Formerly known as Stevenson Ranch, the property was designated as an ecological reserve by the Fish and Game Commission in 2003. From 2008 to 2010 there was restoration of native grasses on a 45-acre site, providing high quality habitat.
