About Case Mountain Grove
Case Mountain Grove is a 42-acre grove in the Kaweah River Watershed region situated between 5,475 - 6,376 feet elevation at 36.41416°N. It is located six miles east of the town of Three Rivers, CA, in the headwaters of Salt Creek and other tributaries to the East Fork of the Kaweah River. The grove is managed by Case Mountain Extensive Recreation Management Area and is part of the Case Mountain Complex - the only sequoia groves managed by the Bureau of Land Management (BLM). Case Mountain Grove is not remote, but it can only be accessed via an 11-mile primitive dirt road that climbs about 5,000 ft. Accessing and using the road is dependent upon weather conditions; the road can get washed out and clay components in the soil can make it very difficult to drive on after inclement weather. Vehicle access is currently limited to BLM personnel and private landowners. The general public can access the grove by foot, equestrian and mountain bike travel only. Portions of Case Mountain Grove were logged in the 1940s and 1950s but it contains areas with old growth sequoias.

Beetle Activity
Beetle Activity in Case Mountain Grove has not been observed by grove managers.
Please see the Grove Resilience Datasheet for details.
Drought-related Tree Mortality (all species)
The drought- and insect-related mortality of all tree species combined in Case Mountain Grove is estimated as Medium according to USFS dead canopy surveys from 2017-2021. Please see Grove Assessment Analysis Methods for details.
The table below provides information about large wildfires in this grove recorded since 1984. See this map of wildfires and locations of high severity fire.
| Metric | Value |
|---|---|
| Wildfires | CASE - 1987 |
| % of grove burned | 90.10000000000001% |
| % of grove unburned | 9.9% |
| Fire Return Interval Departure | High |
The chart below provides the percentages of the grove burned at different levels of severity for each wildfire since 1984.

Management Considerations
Case Mountain Grove is ranked Low for Relative Management Priority because it has Low Relative Overall Vulnerability and Good feasibility for implementing management actions toward restoration goals.
Additionally, the grove is 2.4 miles from a community and is 4.8 miles from recreational infrastructure. There are historic skid trails that could be used to implement management activities. Restoration treatments are sometimes infeasible due to steepness in the grove, but feasibility is determined on a case-by-case basis. There is a presence of pre-settlement and historic archeological sites. See below for more detailed information.
