Yosemite National Park is an American national park located in the western Sierra Nevada of Central California, bounded on the southeast by the Sierra National Forest and on the northwest by the Stanislaus National Forest. The park is managed by the National Park Service and covers 748,436 acres and is located in four counties: concentrated in Tuolumne and Mariposa, extending north and east to Mono and south to Madera County. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, crystal-clear streams, giant sequoia ranges, lakes, mountains, grasslands, glaciers, and diversity. biology. Nearly 95% of the park is designated wilderness.

Yosemite is one of the largest and least fragmented habitat areas in the Sierra Nevada, and the park supports a wide variety of plants and animals. The park ranges in elevation from 2,127 to 13,114 feet and has five main vegetation zones: chaparral and oak forests, subalpine forests, alpine forests, subalpine and alpine forests. Of California’s 7,000 plant species, about 50% occur in the Sierra Nevada and more than 20% are in Yosemite. The park has suitable habitat for more than 160 rare plant species, with rare geological formations and unique soils that characterize the limited range that many of these plants occupy. The geology of the Yosemite area is characterized by granite and remnants of old rocks. About 10 million years ago, the Sierra Nevada was uplifted and then tilted to form relatively gentle western slopes and more dramatic eastern slopes. Uplift increases the slope of streams and river beds, leading to the formation of deep, narrow canyons. About a million years ago, snow and ice accumulated, forming glaciers in alpine meadows that moved down into river valleys. Ice thickness in Yosemite Valley may have reached 4,000 feet during the first glaciation. The downward movement of the ice blocks cut and sculpted the U-shaped valley that attracts scores of visitors to its stunning scenery today. The name “Yosemite” was originally the name of a tribe driven out of the area by the Mariposa Battalion. Previously, this area was called “Ahwahnee” by the natives.
