Martinez Canyon - Cottonwood Springs

Map     Satellite

A variety of habitats is included in this large area which is an important part of the rare Peninsular bighorn sheep, Ovis canadensis cremnobates, range. Habitats range from low desert to ponderosa pine forest in the higher elevations, and include such communities as creosote bush scrub, desert wash, pinyon-juniper woodland, and oak woodland.  The ocotillo, Fouquieria splendens, found in the creosote bush scrub, is here near the western limits of its range. Two rare plants, Penstemon californicus and Salvia eremostachya, occur in the area.

There is an equal diversity of animals.  Among the more noteworthy, aside from the sheep, are the Southwestern toad, Bufo microscaphus, an uncommon species of irregular distribution, and a variety of reptiles, including the speckled rattlesnake, Crotalus mitchelli.

Much of the area is a rugged, mountainous terrain with rocky slopes, chiefly metamorphosed granite. Numerous canyons showing Quarternary terracing dissect the area.  Springs are found in many canyons. There are archaeological sites in the area.

Integrity:  Virtually undisturbed.

Use:  Research, educational, observational, light recreational.
