The giant-sequoia is a massive evergreen tree, maturing to 250 ft. high with a girth of 80 ft. Bluish-green needles are crowded and spirally arranged on the twigs. The fluted trunk and red-brown bark are attractive landscape features, revealed as the tree loses its lower branches. The tree retains a narrow, pyramidal crown of foliage in the upper reaches at maturity. One of the world’s largest trees with fibrous, reddish-brown trunk much enlarged and buttressed at base, fluted into ridges, and conspicuously narrowed or tapered above; narrow, conical crown of short, stout, horizontal branches reaches nearly to base. Giant trees have tall, bare trunk and irregular, open crown.
This rare species ranks among the worlds oldest trees; felled trees show annual rings indicating up to 3200 years of age. Almost all Giant Sequoias are protected in Yosemite, Kings Canyon, and Sequoia national parks, in 4 national forests, and in state parks and forests. It is a popular, large ornamental tree in moist, cool temperate climates along the Pacific Coast and around the world. The lumber is no longer used, although many trees were cut and wasted in the early logging days. Seedlings and saplings are killed by forest fires, but the very thick bark of mature trees offers resistance. Douglas squirrels cut and store quantities of mature cones, and sparrows, finches, and chipmunks destroy many seedlings.
