Very similar to Open Engelmann Oak Woodland (71181), but has Quercus agrifolia as an additional significant constituent. Canopy cover is very similar to that observed in Open Engelmann Oak Woodland, but stem densities are much greater due to Quercus agrifolia being superimposed on the Quercus engelmannii.
SITE FACTORS:
On slightly more mesic sites (especially in steep canyons) than Open Engelmann Live Oak (71181). Intergrades also with Coast Live Oak Woodland (71160) at slightly higher elevations on even more mesic sites.
DISTRIBUTION:
Mainly in the Santa Ana and other Peninsular ranges.
