BHR Peninsula Background
On the Peninsula Watershed, we have restored native habitat around Homestead Pond, (a productive breeding area for the California red-legged Frog at the watershed’s southern end), and we have revived new wetlands along Upper Crystal Springs and San Andreas reservoirs.

The last phase of our long-term habitat restoration project is now under way: to bring back, monitor and maintain approximately 180 acres of native oak woodland and grassland. These are historic habitats that provide essential food and shelter for a variety of native California plant, butterfly, birds and other wildlife species—some found nowhere else in California.
However, over the decades, invasive non-native trees and other vegetation has displaced theose original plant communities and the ecosystems they support, especially east of Crystal Springs and San Andreas reservoirs. In the course of the next two years, new acorn, grass and other native plantings will be distributed across a dozen sites near and along the two reservoirs.
Preparing the Way
Crews remove invasive shrubbery and other low-growing vegetation by hand.
Our efforts to establish those new habitats would be unsuccessful without measures first to remove and control the invasive vegetation, including acacia, eucalyptus and pines from the restoration sites. Otherwise, the new young plantings would not be able to compete with the invasive growth, or survive in the understory. Our first removal efforts started with acacias near and within view of Sawyer Camp Trail, in spring 2016. See a map of the affected areas within the watershed. Over a two-year period, 2016-2018, a total of approximately 72 acres of non-native trees will be removed from various sites in the Crystal Springs and San Andreas reservoir area. All trees slated for removal were identified by certified biologists. Subsequent plantings of about 180 acres of native grasses and oak woodlands will be followed by maintenance and up to 10 years of performance monitoring.
