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. January 1981
