About Bearskin Grove

Bearskin Grove is a 69-acre grove in the Kings River Watershed region situated between 5,985 - 6,579 feet elevation at 36.74605 °N. It is managed by Giant Sequoia National Monument/Sequoia National Forest. The grove is separated into two units, a larger east unit and a west unit. They are on opposite sides of a low ridge southeast of Bearskin Creek, tributary to Ten Mile Creek, in the Kings River watershed. The grove has several outliers, including a group along Bearskin Creek. There were two sequoia and mixed conifer plantations in this grove from the 1970s - 1980s that were involved in experiments testing to see how much fire it took to achieve surviving natural regeneration. The area experienced heavy logging in the 1980s, but most mature sequoias were left untouched. At least 85 mature sequoias remain today.

Bearskin Grove

Health & Resilience

Bearskin 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, Bearskin Grove is at Low 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 Unknown. 0% of Bearskin Grove has burned in large fires since 1984. See below for more detailed information.

Relative Overall Vulnerability
Components of Relative Overall Vulnerability

Relative Overall Vulnerability is based on Wildfire Vulnerability and Regeneration Vulnerability using an area-weighted calculation. See Grove Assessment Analysis Methods for more details.

Additional Grove Health & Resilience Information

Below is additional information about Bearskin 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 Bearskin 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 Bearskin Grove is estimated as Low according to USFS dead canopy surveys from 2017-2021. Please see Grove Assessment Analysis Methods for details.

Wildfire History

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.

Bearskin Grove

Management Considerations

Bearskin 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 1.9 miles from a community and is 0.9 miles from recreational infrastructure. Bearskin Grove experiences a high volume of day-use recreation. There is a California Spotted Owl PAC; nesting in this grove has occurred for years. There are two prehistoric sites in the grove. See below for more detailed information.
