Jamul Mountains

MAP     Satellite

Chaparral covers the Jamul Mountains.  Approximately sixty percent is chamisal, virtually pure chamise, Adenostoma fasciculatum, with some Xylococcus bicolor.  The remainder is a mixed chaparral, with Adenostoma fasciculatum, Ceanothus tomentosus olivaceus, and scrub oak, Quercus sp., conspicuous elements.

This area is one of the two known sites in the United States where Fremontodendron mexicanum occurs and one of three where Satureja chandleri is found. It is also the type locality for the uncommon grass, Achnatherum diegoensis.

Animal life is relatively abundant and typical of the region.

Geologically, the mountains are underlain by Jura-Triassic metavolcanics.

Integrity:  There are several small reservoirs and some trails in the area.  Portions are lightly grazed.  Much of the area is in excellent condition.

Use:  Mostly private.  Research, educational on public portion.
