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 Endemic flora of the State of California — native plants found within its borders, and nowhere else in nature.; 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.
A small group [citation needed] of Sierra Nevada alpine plants can found around the world in northern latitudes, which is called (circumboreal). [4]: 225 An example is bush cinquefoil (Potentilla fruticosa), [4]: 225 which ranges throughout arctic regions of Alaska, Labrador, and the high mountains of Eurasia. [5]: 187 [9]
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.

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 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 ...
The polar jet stream in the winter brings with it rain and snow. The jet stream is an extremely powerful air current flowing west to east often at over 100 miles per hour. The precipitation in the region is closely associated with winter frontal storms from the Pacific Ocean, which bring cool air and rain to the area.
Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere , and it contains land and the islands that surrounds it.
