About Mountain Home Grove
Mountain Home Grove is the largest giant sequoia grove at 2,801 acres. It is in the Tule and Kern River Watershed region situated between 4,308 - 7,257 feet elevation at 36.23189°N. The grove is managed by Mountain Home Demonstration State Forest, Tulare County, and Giant Sequoia National Monument/Sequoia National Forest. Dwight Willard (1994) describes the grove as “primarily on the Mountain Home plateau with a major extension east and northeast into the canyon of the North Fork of the Middle Fork of the Tule River. Most of the plateau is in the headwaters of Rancheria and Bear Creeks. On the east, the grove generally extends beyond the plateau into upper elevations of the river canyon. The grove is narrowly continuous between the plateau and the canyon bottom in the Moses Gulch drainage.” Mountain Home Grove contains many large and ancient giant sequoias, including the Genesis Tree - the seventh largest living sequoia. The grove was heavily logged in the late 19th century, but many old growth sequoia trees were left intact. It has a long history of mechanical and fire-related treatments, which has contributed to its resiliency against destructive wildfire. There is a high amount of recreational use in the Mountain Home Grove.

Health & Resilience
Mountain Home Grove is ranked Low for Relative Overall Vulnerability because it is at a Low risk of being negatively impacted by the effects of severe wildfire and at Low risk for inadequate natural regeneration.
Additionally, Mountain Home Grove is at Moderate risk for negative impacts from drought stress, Low levels of tree mortality have been detected in the grove, and the presence and activity of beetles in the grove is Confirmed. 100% of Mountain Home Grove has burned in large fires since 1984. See below for more detailed information.
