Flora
See also: Category: Flora of Baja California SurThe composition of the pine-oak forests varies with elevation; oak woodlands predominate from 800 to 1200 meters elevation, with oak-pine woodlands between 1200 and 1600 meters elevation, transitioning to pine-oak forests above 1600 meters elevation. Mosses and lichens are abundant throughout.
The oak woodlands from 800 to 1200 meters elevation are warmer and drier, with evergreen oaks predominant (principally Quercus devia; Quercus arizonica and Quercus rugosa have a limited distribution), along with lower trees and shrubs such as Dodonaea viscosa, Sideroxylon peninsulare, and Buddleia crotonoides.
Above 1200 meters elevation, the oak woodlands transition to oak-pine forests. The only pine present is an endemic subspecies of Mexican Pinyon, Pinus cembroides subsp. lagunae, mixed with oaks, including Quercus devia and Quercus tuberculata, and other broadleaf trees, including Arbutus peninsularis and Nolina beldingi. Lower trees and understory shrubs include Calliandra peninsularis, Mimosa xanti, Heterotoma aurita, Verbesina pustulata and Hypericum peninsulare. Above 1600 meters elevation, pine predominates, mixed with oaks, and with an understory of grasses (Muhlenbergia spp. and Festuca spp.).
