About Santa Rosa Plateau Ecological Preserve

Santa Rosa Plateau Ecological Preserve
 

Located in southwestern Riverside County near Murrieta and Temecula, the Santa Rosa Plateau Ecological Preserve protects one of the largest remaining tracts of Southern California's coastal sage scrub and native grasslands. The preserve encompasses over 9,000 acres featuring vernal pools, oak woodlands, and engaging rolling hills. It supports a rich diversity of plant and animal species, including the rare California gnatcatcher and the Quino checkerspot butterfly. Established in 1984, the preserve also preserves historical sites such as Native American artifacts from the Luiseño people and remnants of ranching history. Visitors can enjoy nearly 40 miles of multi-use trails designed for hiking, mountain biking, and horseback riding. The main trailheads begin at the historic Santa Rosa Ranger Station, which includes a visitor center offering educational exhibits and nature programs. Key landmarks include the vernal pools—seasonal wetlands that burst to life in the spring—and the Banning Ranch Oaks, some of the oldest trees in the region. The preserve offers opportunities for wildlife viewing, bird watching, photography, and quiet reflection in a natural setting. Educational tours and volunteer programs often help visitors learn about local ecology and conservation efforts. The area’s Mediterranean climate makes it ideal for visiting year-round, though spring blossoms and fall colors are particular highlights. The Santa Rosa Plateau Ecological Preserve remains a vital natural refuge amidst Southern California's expanding urban landscape, drawing both local residents and eco-tourists seeking outdoor recreation and appreciation of native species.
