Notes: Klamath Mammoth, also known as Tree 49, is the fastest-growing tree yet measured. It gained more than 2,205 lb (1,000 kg) aboveground biomass each year, on average, during the last century and 2,811 lb (1,275 kg) aboveground biomass in 2014. Klamath Mammoth also has the largest redwood crown yet measured: 82 ft (25 m) width, 282 ft (86 m) depth, volume 1,000,676 ft3 (28,336 m3).
Klamath Mammoth grows beside High Prairie Creek in the Yurok Research Natural Area of Redwood Experimental Forest which was established in 1940 to improve coast redwood silviculture. Ample sunlight, from canopy gaps created after the surrounding forest was logged in 1960, and abundant water from the nearby creek provide optimum conditions for Klamath Mammoth's rapid growth.
Although Redwood Experimental Forest remains inaccessible to the general public, parts of the forest are visible from the observation deck at Ted's Ridge, near the SkyTrail gondola terminus, at Trees of Mystery (admission fee required) nearby.
