Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).
The most common plant communities are pine forest, pine–oak forest, oak forest, and oak or pine-oak woodland, with smaller areas of mixed conifer forest, mesophytic forest, montane meadow, primary or secondary chaparral, and juniper scrub. [4] Pine forests occur from 1600 to 3200 meters elevation under a variety of conditions. The species ...
The deserts in California receive between 2 and 10 inches (51 and 254 mm) of rain per year. [6] Plants in these deserts are brush and scrub, adapted to the low rainfall. Common plant species include creosote bush, blackbrush, greasewood, saltbush, big sagebrush, low sagebrush, and shadscale. [6]
All three oak species which characterize California oak woodlands can be defined as "long-lived, slow-growing trees." [6] The frequent fires seen within the region have resulted in species such as coastal live oak and Englemann oak (which grow in drier, more fire prone regions) to have developed a resistance to low-intensity fires.
The most common tree in the subalpine forest is the whitebark pine. [10] The western white pine, mountain hemlock, and lodgepole pine are also found in this forest with many subalpine meadows that flower from July through August. [3] Many species live in, or are transient in, this zone, including Clark's nutcracker. [4]
The trees are a variety of needle-leaved and broad-leaved evergreen species. Characteristic trees include coast Douglas-fir (Pseudotsuga menziesii var. menziesii), canyon live oak (Quercus chrysolepis), tanoak (Notholithocarpus densiflorus), madrone (Arbutus menziesii), California bay laurel (Umbellularia californica), and golden chinquapin ...
This list includes most of the more common plants to be found on the Modoc National Forest in California, USA as well as plants of some particular note, especially rare plants known or suspected to occur there. If you click on the genus, you will be taken to the page for the genus only; you must click on the specific epithet to be taken to the ...
Canyon live oak, California black oak, and Pacific dogwood are other trees that also grow here. The forest contains an estimated 87,400 acres (354 km 2) of old growth. The most common types are Sierra Nevada mixed conifer forests, white fir (Abies concolor) forests, Jeffrey pine (Pinus jeffreyi) forests, and lodgepole pine (Pinus contorta ...
