GENERAL DISTRIBUTION : 
Coast is distributed along the Coast, Transverse, and Peninsular ranges
and the Sierra de Juarez from Sonoma County, California south to Canada
El Piquillo, Baja California [5,35,54,58].  Limited inland populations
occur along watercourses in the Central Valley [38,42].  Coast live oak
is also found on the Channel Islands of Santa Rosa and Santa Cruz
[18,65].

HABITAT TYPES AND PLANT COMMUNITIES : 
Coast live oak is the most conspicuous tree in lower elevation woodlands
of southern California [33].  The southern oak woodland, describing
various woodlands of southern California, contains many phases in which
coast live oak is dominant or codominant.  The coast live oak phase
varies in structure from dense stands to open savannas [17,19].  Coast
live oak woodland may be monospecific or mixed.  Frequent codominants
include bigcone Douglas-fir (Pseudotsuga macrocarpa) and Engelmann oak
(Quercus engelmannii) [32].  Southern California coast live oak woodland
also has a chaparral phase, dominated by shrubby coast live oak
subjected to frequent fire.  Canyon live oak (Q. chrysolepis) is a
common chaparral codominant [39].  Coast live oak frequently codominates
in California walnut woodland [32].

Coast live oak is a frequent dominant or codominant of mixed evergreen
forests of northern and southern California [33,79], where these oaks
codominate with valley oak (Q. lobata), blue oak (Q. douglasii),
California black oak, interior live oak, California bay (Umbellularia
californica), and Digger pine (Pinus sabiniana) [17].  In riparian
areas, it codominates with western sycamore (Plantus racemosa), white
alder (Alnus rhombifolia), and red alder (A. rubra).
