Area # 16
Name: Buzzard Peak/San Jose Hills
Quadrangle(s): San Dimas
Class 7

Resource Description: Buzzard Peak is one of three areas in the hilly region of eastern Los Angeles County that still supports a relatively undisturbed stand of the southern oak woodland, chaparral, coastal sage scrub, riparian woodland complex that was once common there. The remainder of this vegetation type has been converted to agricultural and urban uses. This is true throughout the entire southern California region, making it one of the most rapidly disappearing habitat types. These three areas were chosen to serve as representative samples of this once widespread community.

The vegetation and wildlife on Buzzard Peak are in relatively good condition. This is due in part to the buffering provided by the California State Polytechnic University at Pomona, Mt. San Antonio Junior College, and Forest Lawn Memorial Park. It is also a result of the area being a peak, thus isolating it from disturbances that mould arise from an upstream or up-slope source. The area adjacent to Cal Poly supports dense groves of California walnut. This species is uncommon outside Los Angeles and Ventura Counties, and has one of its major populations in this hilly region. Buzzard Peak is of sufficient size and in close enough proximity to the other recommended areas in this region, that is should be able to continue to support relatively healthy animal populations if preserved.

Status: Buzzard Peak is undeveloped and unroaded. It is protected on the north by Forest Lawn Memorial Park, on the east by California State Polytechnic University, and on the south by Mt. San Antonio Junior College. Urban encroachment is occurring on the west end.

Information Source(s): Survey/Interview, ERC/UCLA, CNACC/CNPS.

Nature of Information: Due to the California Natural Area Coordinating Council project, and the efforts of the Environmental Resources Committee, competent biologists have made surveys of the area.

Buffer Zone Requirement: None. Resources will be protected by recommended boundaries.

Compatible Uses: Low intensity recreational uses are compatible with the resources of the area.
