Tedoc Mountain
Map Satellite
Tedoc Mountain, a semi-isolated peak situated in a serpentine area, is of particular interest botanically. On the serpentine soils the open forest is composed of Jeffrey pine, Pinus jeffreyi, and incense cedar, Calocedrus decurrens; on other soils the forest is mixed evergreen with ponderosa pine, Pinus ponderosa, and Douglas fir, Pseudotsuga menziesii, dominants.
At least five rare plants are found here, including Minuartia rosei, Eriogonum alpinum, Lomatium tracyi, Asclepias solanoana, and Ericameria ophitidis. This is the type locality of the latter which is known from only one other site. The Asclepias is near the northern limit of its distribution, as is Collomia diversifolia. The uncommon Streptanthus barbatus is near the southern limit of its range here, as is the Arenaria, Eriogonum strictum var. proliferum and Collomia tracyi. Allium platycaule, a northern Sierran and Great Basin native, is found in the area, its only known site in the Coast Ranges. Another Sierran native, Allium hyalinum, is present here also. The Great Basin species Antennaria dimorpha is also known in the Coast Ranges from only this site.
Integrity: Virtually undisturbed, though there is a dirt road in the area.
Use: Educational, research, observational.
