Cowles Temescal Canyon Reserve

MAP     Satellite

Located near the crest of the Santa Monica Mountains, much of the terrain in this Reserve consists of relatively steep-sided canyons.

Coastal sage scrub and chaparral are the dominant communities.  In the former, such species as buckwheat, Eriogonum fasciculatum, black sage, Salvia mellifera, chia, Salvia columbariae, and lemonade berry, Rhus integrifolia, are present; in the latter, chamise, Adenostoma fasciculatum, Arctostaphylos glandulosa, Ceanothus spinosus, Ceanothus megacarpus, mountain mahogany, Cercocarpus betuloides, toyon, Heteromeles arbutifolia, laurel sumac, Malosma laurina, sugar bush, Rhus ovata, scrub oak, Quercus berberidifolia, and Yucca whipplei are found.

Some oak woodland occurs, with coast live oak, Quercus agrifolia, and California walnut, Juglans californica. Along the intermittent stream courses there is a riparian woodland with sycamore, Platanus racemosa, and California bay, Umbellularia californica.

Animals are typical of the mountains and relatively abundant.

A cold spring and seep are located within the Reserve. Shale with some altered sandstones, dating from the upper Cretaceous and Oligocene, occur in the area.

Integrity:  All of the area was burned over in 1961, a portion in 1938.

Use:  Research, educational.
