Yosemite is one of the largest and least divided habitat blocks in the Sierra Nevada, and the park supports a variety of plants and animals. The park has an altitude scope from 2,000 to 13,114 feet (600 to 4,000 m) and contains five leading flora zones: chaparral/oak forest, lower montane, upper montane, subalpine, and alpine. Of California’s 7,000 plant species, about 50% in the Sierra Nevada and much than 20% within Yosemite. There is appropriate habitat or certification for much

than 160 uncommon plants in the park, with uncommon local geological formations and unusual soils characterizing the restricted ranges many of these plants invade. The geology of the Yosemite region is characterized by granitic rocks and remnants of old stone.

About 10 million years ago, the Sierra Nevada was uplifted and so inclined to organize its comparatively mild southwestern slopes and the more spectacular eastern slopes.
