Quercus douglasii, known as blue oak, is a species of oak endemic to California, common in the Coast Ranges and the foothills of the Sierra Nevada. [4] It is California's most drought-tolerant deciduous oak, [5] and is a dominant species in the blue oak woodland ecosystem. It is occasionally known as mountain oak and iron oak. [6] [7]
Quercus agrifolia, the California live oak, [3] or coast live oak, is an evergreen [4] live oak native to the California Floristic Province.Live oaks are so-called because they keep living leaves on the tree all year, adding young leaves and shedding dead leaves simultaneously rather than dropping dead leaves en masse in the autumn like a true deciduous tree. [5]
The Sierra Nevada alpine zone lacks a dominant plant species that characterizes it, so may or may not be called a vegetation type. [7] But it is found above the subalpine forest, which is the highest in a succession of recognized vegetation types at increasing elevations. [1] [6]: 17
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 Santa Monica Mountains are covered by hundreds of local plant species: some are endemic or very rare, some are beautiful California native plants in situ, and some also are familiar as horticultural ornamental and native garden plants. Each season has different plants predominating the visual experience.
Winds can be high throughout the year and are a major factor limiting plant growth near the upper limit of the subalpine zone (tree line). Wind limits vegetative growth chiefly in two ways: by physically battering plants, including blowing snow and ice, and by increasing evapotranspiration in an environment that is already water-stressed.

Joshua trees are already struggling to reproduce in a warming climate. Replacing those lost in the York fire may be all but impossible, experts fear. California's famed Joshua trees are burning up ...
The "Henley Oak", in Covelo, California, is the tallest known valley oak, at 47 m (153 ft). [7] [8] The branches have an irregular, spreading and arching appearance. During autumn, the leaves turn a yellow to light orange color but become brown later in the season. In advancing age, the branches droop. The trees have pewter-colored rippled bark ...
