Giant sequoia trees in the United States In the northeastern USA there has been some limited success in growing the species, but growth is much slower there, and it is prone to fungal diseases due to the hot, humid summer climate there. Within groves, trees are densest in moist areas, such as drainage bottoms and meadow edges. Since the 1890's, most of the groves of giant sequoia have been protected by California state parks and Yosemite, King's Canyon, and Sequoia National Parks so that all Californians may enjoy their stately grandeur. The second agent is the chickaree, or Douglas squirrel (Tamiasciurus douglasi). In fact, giant sequoias are the largest living things to ever inhabit the earth and are among the tallest.

In the northern part of its range (American River, Placer County to Kings River) there are only eight small separate groves, of which three are contained within the borders of Yosemite National Park. The wood from huge old-growth giant sequoia trees does not make good lumber, despite the its resistance to decay, because it is brittle and has little strength. Sequoias regenerate by seed, by stump sprouting when injured, and artificially by cuttings. The fleshy green scales of the young cones are a major food source for the squirrel.

The first agent is the long-horned wood-boring beetle (Phymatodes nitidus). Nevertheless, large vigorous individuals do grow in shallow and rocky soils when underground water is available. The Giant Sequoia (Sequoia giganteum), and its close relative the coast redwood (Sequoia sempervirens) are the two remaining "relic" species. The younger the tree the more susceptible to the color change it is. Agriculture Handbook 654.

However, trees planted in nurseries and outside the giant sequoia's natural range are more susceptible to disease and insect damage. Climate in the coast redwood's natural range is moderate with precipitation ranging 25-122 inches annually, mostly as winter rain, but with a large degree of fog drip. The sequoia seems to reach such heights because of its ability to grow rapidly and continue growing into old age. Temperatures can vary 20 to 30 degrees as you change elevation.
