Park Creation Timeline
On June 30, 1864, President Abraham Lincoln signs the bill creating the Yosemite Grant, given to the state of California to form Yosemite State Park.
On October 1, 1890 Congress passes the bill creating Yosemite National Park. California retains control of the valley and Mariposa Grove.
President Theodore Roosevelt signs the bill that takes back the valley and Mariposa Grove and adds it to the national park.
The park is named a World Heritage Site by UNESCO (United Nations Educational, Scientific and Cultural Organization).
Animals and Plants
There are 90 known species of mammals in the park. They include mule deer, black bear, bobcat, mountain lion, coyote, foxes, raccoon, bats, chipmunks, squirrels, and gophers.
12 amphibian and 22 reptile species inhabit the park. Common lizards include the western fence and the northern and southern alligator lizards. Snakes include three species of garter snake, mountain king snakes, rubber boas. Only the western rattlesnake is venomous. Amphibians include the western toad and its relative, the endemic Yosemite toad, and five species of frogs, along with salamanders and newts.
Over 150 species of birds regularly occur in the park, with around 80 additional species that have been seen in Yosemite only a few times. With such a number, listing them here is not practical, but the NPS has produced a PDF file of Yosemite's bird species
The park's huge elevation range leads to five different plant zones. The Foothill Woodland Zone is found at the lowest elevations, gets almost no precipitation, and includes manzanita and blue oak. Next is the Lower Montane Forest which includes ponderosa pine, incense cedar, and white fir, along with the giant sequoias. The Upper Montane Forest lies further up and is characterized by red fir and lodgepole and jeffrey pine. The Subalpine Forest, just below treeline, is filled with western white pine, mountain hemlock, and lodgepole pine. The Alpine zone is above treeline and contains mostly herbaceous plants with quick growing seasons.
