Alder Creek Grove is a giant sequoia grove located both on private land and within the Giant Sequoia National Monument in the western Sierra Nevada of California. The grove is spread out over approximately 785 acres (318 ha) of land and contains 526 giant sequoias that are at least 6 feet in diameter, including the Stagg Tree, the 5th largest tree in the world and one of the oldest known living giant sequoias. It is estimated that approximately 200 mature giant sequoias died in the grove from the 2020 Castle Fire, part of the SQF Lightning Complex.
