James San Jacinto Mountains Reserve

Map     Satellite

This Reserve is situated near the lower boundary of the transition forest on the slopes of San Jacinto. It lies entirely within the Black Mountain Scenic Area.

Two stream courses flow through the area.  One is permanent and supports a diverse riparian flora, including the Western azalea, Rhododendron occidentale, which here is near the southern limits of its range, and the white alder, Alnus rhombifolia.

Much of the Reserve is in mountain meadowland covered with grasses, low annuals and bracken fern. On the protected slopes three species of pine are abundant, Coulter, Pinus coulteri, yellow, Pinus ponderosa, and sugar, Pinus lambertiana.  Incense cedar, Calocedrus decurrens, and white fir, Abies concolor, are also present.  There are four species of oak, coastal scrub, Quercus berberidifolia, interior scrub, Quercus wislizenii, black, Quercus kelloggii, and canyon, Quercus chrysolepis, on the Reserve.

Exposed slopes generally support open stands of high-altitude chaparral dominated by Ceanothus leucodermis, Ceanothus palmeri, Arctostaphylos pringlei and Arctostaphylos pungens.

Animals are abundant and include most species found in the southern California transition forests.  Among the more colorful breeding birds are the Western tanager, Piranga ludoviciana, black-headed grosbeak, Pheucticus melanocephalus, and the calliope hummingbird, Stellula calliope.  The rare southern rubber boa, Charina bottae umbratica, may be found here.

At least one archaeological site is said to exist on the Reserve.

Integrity:  This Reserve is included in the University of California Natural Land and Water Reserves System.  The former owners preserved much of the original surroundings.  There are several buildings on the Reserve, including a cookhouse and cabins.

Use:  Research, educational, observational.
