The vegetation found in the area is coastal sage scrub. This plant community supports a surprising number and variety of species. There are at least three races of birds resident on the peninsula that are found nowhere else except the Channel Islands. These are the insular forms of the orange-crowned warbler, Pacific-slope flycatcher, and Allen's hummingbird. The same phenomenon has been documented for plant species. A species of live-forever, "Dudleya virens", which is native to the Channel Islands and the Palos Verdes Peninsula, is found near Point Vicente Lighthouse, which was built in 1926.
