About McKinley Grove

McKinley Grove is a 57-acre grove in the Kings River Watershed region, situated between 6,216 - 6,698 feet elevation at 37.02300°N. It is managed by the Sierra National Forest. The grove is located in the North Fork of the Kings River watershed, within the drainage of an unnamed tributary to Dinkey Creek. Relative to other giant sequoia groves, it is one of the most isolated; second only to Placer County Big Trees Grove. Some areas of the grove were logged in the late 19th century, but none of the old growth sequoias were logged. Prior to the Garnet Fire of August 2025, wildfire had not been recorded in this grove for nearly a century.

McKinley Grove

Health & Resilience

McKinley Grove is ranked Moderate for Relative Overall Vulnerability because it is at a Moderate risk of being negatively impacted by the effects of severe wildfire and at Low risk for inadequate natural regeneration.

Additionally, McKinley 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. 100% of McKinley Grove has burned in large fires since 1984. See below for more detailed information.
