No big surprise, but Giant Sequoias are only native to California. This species of the Cupressaceae family is the only member of its genus Sequoiadendron. The trees are also called big tree and Sierra Redwood. They are so large, they often have monikers. The largest standing today is the General Sherman which has a volume of 52,500 cubic feet and is over 274 feet tall. Due to their height and trunk volume, these trees are often referred to as the largest living things on earth. General Sherman is not the tallest known Giant Sequoia. The tallest is said to be over 300 feet and grows in a known grove but the exact tree is not specified. Sequoias may also be some of the most long-lived, as the oldest one by stump count in 1870 was 3266 years.
As this tree grows fast even in old age, it is possible the General Sherman will get both taller and wider! Although Giant Sequoias would provide a lot of wood per tree, most of them are protected. Once used for fenceposts, their wood is rot resistant but also brittle, making it less than ideal for building. The local Native Americans, members of the Tule River Tribe, did use the wood for fenceposts and crafts, but instead of felling the trees, they utilized downed wood. After the white man discovered the Sequoia, many were lumbered, eventually leading the preserved groves to be added to the National Park System.
North American Trees (Preston and Braham, 2002) mention that a “dark red pigment in ink” can be obtained from the cones. One advantage of having a smaller tree in the park is you can feel the leaves, which I think are the prickliest of the conifers. They hurt!
This short video discusses the lifecycle of the sequoias. At one time the conditions for these trees to grow may have existed as far east as Colorado. Changes to the climate affecting California may not bode well for the Sequoias as well as other other trees. In 2017 the Pioneer Cabin Tree, which you could drive through, fell during a severe rainstorm.
Sequoias have been planted elsewhere in the world, including Denmark and France. In the mid 1800s, Giant Sequoias were a popular addition to English castle gardens, where conditions appear to be ideal. Some of the largest specimens in Europe can be found in Great Britain. In the relatively few tree-years since then, some specimens have acquired height of around half the tallest in the US. Another group of trees which were planted in Denmark to help with reforestation, where killed in the winter of 1942. Today many visitors from around the world take home seeds to grow the trees.
To find B116 Giant Sequoia (Sequoiadendron giganteum) go to the triangle formed at Oak, Jackson, and City Park. In this area is a stone bench. If you were to sit on the bench facing south you would be looking toward the Giant Sequoia, which is parallel to the lamp post.
