History

In 1946, much of Alder Creek Grove was purchased by the Rouch family to be logged and developed. The grove was logged in the late 1940s and early 1950s. However, doing so proved to be uneconomical due to the brittle nature of

wood, and the regret the family felt logging them. About two dozen giant sequoias were cut down. A 236-lot subdivision of mostly summer cabins, called Sequoia Crest, was built in and adjacent to the grove around the same time so people could visit the Stagg Tree and some of the surrounding giant sequoias. A short-lived ski resort was also established to make the land more profitable for the Rouch family. On September 17, 2019, the

announced it was raising $15.65 million to buy 530 acres from the Rouch family to formally protect the giant sequoias found there, including the Stagg Tree. The nonprofit group was able to acquire the property—the largest private holding of unprotected sequoias at the time—raising funds from more than 8,500 donors worldwide, including from every U.S. state and 30 other countries. After acquiring the parcel, Save the Redwoods League planned to retain and steward the Alder Creek property for 5–10 years before handing it over to the

so the property could be cooperatively stewarded with the portion of the grove already managed by the U.S. Forest Service. The Stagg Tree will then become the largest giant sequoia on land managed by the U.S. Forest Service, edging out the Boole Tree of Converse Basin Grove, the current largest on forest service land.


Castle Fire

On September 13, 2020, the high-intensity Castle Fire, part of the SQF Lightning Complex, swept through the Alder Creek Grove. An assessment of the wildfire in 2021 showed that 200 mature sequoias were killed and another 49 were severely damaged in the Alder Creek Grove, which is approximately 47% of the giant sequoias over in diameter in this grove. The Stagg Tree survived in part because firefighters ran hoses and turned on sprinklers at its base. The Sequoia Crest subdivision lost 46 of 102 homes. In 2020, 19 sequoia groves burned in wildfires, and it is estimated that the SQF Complex caused the death of 10-14 percent of mature giant sequoias. Range-wide giant sequoia grove research and restoration has progressed, largely led by th
Giant Sequoia Lands Coalition
a multi-partner collaboration dedicated to the conservation and stewardship of giant sequoia grove ecosystems. The U.S. Forest Service and Save the Redwoods League, both coalition members, are actively leading restoration programs in the Alder Creek Grove and in other parts of the sequoia range. They have been conducting post-fire restoration in the Alder Creek Grove since 2021 to remove some standing dead trees and combustible, overgrown vegetation to reduce the risk and severity of future wildfires. In 2023, they planted more than 30,000 giant sequoia seedlings and 20,000 other native trees in areas where mature seed trees died and natural regeneration has been low. In 2024, two cultural burns were held at Alder Creek to improve forest health and revive Indigenous land management practices in the grove. Leaders from the

Description

Alder Creek Grove is remarkably diverse, being made up of trees of many different ages and sizes, from seedlings to 3,000-year-old giants. There are also mature stands of red fir, white fir, ponderosa pine, and sugar pine trees mixed in amongst the giant sequoias. The grove is also home to several meadows, wetlands, and lush riparian woodlands.

This tree was also destroyed by the Castle Fire.
