Sequoia National Park was created in 1890 in the southern Sierra Nevada, California, in the United States. The park is famous for its giant sequoia trees, including the General Sherman tree, world’s largest living tree. The first, second, third and sixth tallest trees in the world grow within a mile of each other in Redwood National Park.
There are two different Sequoia species growing here. The giant sequoia (Sequoiadendron giganteum) has huge stout branches, cinnamon bark and massive trunk and the coast redwood (Sequoia sempervirens) has more conifer-like profile, is taller and more slender than giant sequoia.
Some giant sequoia facts.
This amazing tree can grow up to 311 feet (more than 90 meters) for maximum of 3,200 years. The bark can be even 31 inches (78 cm) thick. Bases can be to 40 feet (12 meters) diameter.
Why sequoias don’t die of old age and are resistant to fire and insects?
Chemicals in the bark and wood provide resistance to insects and fungi. Very thick bark insulates those trees from fire.
How do they die?
Most of sequoias die by falling over because they have a shallow root system without taproot. In this case strong winds, root damage or soil moisture can lead to toppling.
