About Carr Wilson Grove
Carr Wilson Grove is a 13-acre grove in the Tule and Kern River Watershed region situated between 4,767 - 6,427 feet elevation at 36.12399°N. It is part of the Belknap Complex and managed by Giant Sequoia National Monument/Sequoia National Forest. The grove is located on Bear Creek and is just southwest of McIntyre Grove. Carr Wilson Grove was formerly considered part of the McIntyre Grove, but now the groves are seen as separate. It is less than a mile away from the nearest community and is home to at least three locally-named giant sequoia trees, but they are not tracked by the Forest Service.

Management Considerations
Carr Wilson Grove is ranked Medium for Relative Management Priority because it has Moderate Relative Overall Vulnerability and Good feasibility for implementing management actions toward restoration goals.
Additionally, the grove is 0.5 miles from a community and is 0.3 miles from recreational infrastructure. The grove has both historic and prehistoric resources. There is a 100-year cabin tract; the long-term goal is to move it out of the grove. Fisher dennings have been observed under the cabin. See below for more detailed information.
