All naturally occurring giant sequoia groves are located in the moist, unglaciated ridges and valleys of the western slope of the Sierra Nevada range in California, United States.
[1] Groves in the northern half of the range (north of the Kings River) are widely scattered and host smaller collections of giant sequoias than groves found within and south of the Kings River watershed.
The total area of all the groves combined is approximately 14,416 ha (35,623 acres).
Currently, the U.S. National Park Service cites Rundel's total of 75 groves in its visitor publications.
