History and Ecology of Mariposa Grove / Giant Sequoias: Located in the southern portion of Yosemite, the Mariposa Grove of Giant Sequoias is the largest sequoia grove in Yosemite and is home to over 500 mature giant sequoias. The national park idea is rooted in the Mariposa Grove. In 1864 President Lincoln signed legislation protecting the Mariposa Grove and Yosemite Valley for "public use, resort, and recreation." For the first time in our nation's history, the federal government set aside scenic natural areas to be protected for the benefit of future generations. Later added to Yosemite National Park in 1906, the Mariposa Grove is a popular destination within the park.

Most of these trees are over 2000 years old and have experienced fire many times throughout their lives. Fire Ecology of Yosemite National Park.

|Current as of|
|Cause||Human Caused/under Investigation|
|Location||Mariposa Grove of Giant Sequoias|
|Incident Description||Full Suppression|
|Coordinates||37.499 latitude, -119.614 longitude|
|Percent of Perimeter Contained||100%|
Very heavy accumulations of available dead surface fuels with ample snags, downed logs, and fuel concentrations in an old growth forest landscape. Representative fuels include multi-species conifer timber with an understory of young conifer and shrubs. Very deep duff and accumulation of timber litter (branchwood and needles) dominate the forest floor. Recent large fire scars in the area include woody fuels and recent shrub growth. Live fuels (shrubs/brush) are seasonally moist and are providing limited intensity and spread.
Aggressive suppression tactics and strategies have mitigated and reduced fire behavior in all areas of the fire.
