About Black Mountain Grove

Black Mountain Grove is a 1,717-acre grove in the Tule and Kern River Watershed region situated between 4,312 - 7,255 feet elevation at 36.11330°N. It is located on Solo Peak, which separates the drainages of the Middle Fork and the South Fork of the Tule River. The grove is managed by Giant Sequoia National Monument/Sequoia National Forest. Black Mountain contains a high density of exceptional sequoias and is home to several notable individuals including the Black Mountain Beauty - the largest living sequoia in the grove. In the early 1970s, it was one of the first sequoia groves to undergo timber harvesting by the Forest Service. The grove was extensively logged for non-sequoia conifers, but most of the old growth sequoias were selectively untouched. In 1980, rights to a portion of the grove were transferred to the Tule River Tribe. The 2017 Pier Fire burned through a large part of the grove and caused severe damage, killing off many non-sequoia conifers. Patches of old growth remain in good condition.

Additional Grove Health & Resilience Information

Below is additional information about Black Mountain Grove's Health & Resilience. These data, their inputs, and any available notes and updates may be found in the Grove Resilience Datasheet.

Beetle Activity
unknown

Beetle Activity in Black Mountain Grove has not been determined.

Please see the Grove Resilience Datasheet for details.

Drought-related Tree Mortality (all species)
low

The drought- and insect-related mortality of all tree species combined in Black Mountain Grove is estimated as Low according to USFS dead canopy surveys from 2017-2021. Please see Grove Assessment Analysis Methods for details.
