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 ecology of California can be understood by dividing the state into a number of ecoregions, which contain distinct ecological communities of plants and animals in a contiguous region. The ecoregions of California can be grouped into four major groups: desert ecoregions (such as the Mojave Desert), Mediterranean ecoregions (such as the ...
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

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 Botanists have ranked the Sierra Nevada alpine zone floral bloom as one of California's foremost wildflower displays, with flowers of fantastic color and abundance. [ 8 ]
Which Southern California native plants survived climate change and mass extinctions 13,000 years ago and still live today? La Brea Tar Pits researchers compiled a list.
The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary vegetation. A biodiversity ...
The largest area of the state is in the Mediterranean climate floristic region, within the California Floristic Province — with the greatest number of endemic plants in North America. The state's other floristic regions include: the low deserts within the Sonoran Desert Floristic Province; the high deserts and eastern borders' dry steppes ...
Chaparral (/ ˌ ʃ æ p ə ˈ r æ l, ˌ tʃ æ p-/ SHAP-ə-RAL, CHAP-) [1] is a shrubland plant community found primarily in California, southern Oregon, and northern Baja California. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires .
