Stebbins Cold Canyon Reserve

Map     Satellite

Most of the Reserve, which lies to the south and east of Monticello Dam, is covered by chaparral. The dominant species are chamise, Adenostoma fasciculatum, scrub oak, Quercus berberidifolia, poison oak, Toxicodendron diversilobum, buck brush, Ceanothus cuneatus, and bush monkey-flower, Mimulus aurantiacus. Many of the steeper, south-facing slopes have grassy clearings with a mixed annual vegetation. To the north are slopes of oak parkland, with blue oak, Quercus douglasii, predominant.

In the canyon bottoms California bay, Umbellularia californica, California buckeye, Aesculus californica, Fremont cottonwood, Populus fremontii, sandbar willow, Salix hindsiana, and redbud, Cercis occidentalis, are found. In the upper part of Cold Canyon, big-leaf maple, Acer macrophyllum, and spicebush, Calycanthus occidentalis, occur.

It is estimated that there are over 250 species of vascular plants in the Reserve.

Wildlife includes species typical of the inner Coast Ranges. Some 79 species of birds have been observed in the Reserve, with perhaps 25 nesting.

The underlying rock consists of uptilted sediments, chiefly Cretaceous sandstones and shales. There is an intermittent stream.

Integrity: Several ruined buildings, a clearing and a pathway to the buildings are present; however, most of the area is virtually undisturbed.

Use: Research, educational.
