Set in the southernmost mountains of the Transverse Ranges, the Stunt Ranch Santa Monica Mountains Reserve is located in the Cold Creek watershed of Malibu Creek, perhaps the most pristine and biologically diverse watershed in the Santa Monica Mountains. Cold Creek itself flows year-round through the reserve. Smaller tributaries of Cold Creek additionally provide the reserve with a welldeveloped corridor of riparian habitat. Primary habitats include chaparral, coast live oak woodland, and annual grasslands. Overall, there are more than 300 vascular plant species. The reserve also harbors an abundance of fauna, particularly birds and reptiles. All of Stunt Ranch burned in 1993, but has recovered well. The site’s natural diversity remains undiminished and continues to provide excellent educational and research opportunities. Research is also possible at other natural areas adjacent to the reserve under management of the National Park Service, California Department of Parks and Recreation, Mountains Restoration Trust, and Santa Monica Mountains Conservancy.
