One of the largest trees on Earth is Boole Tree in California. This giant sequoia is 81.9 m tall and its trunk has a circumference of 24.3 m.

Giant sequoias

Giant sequoias are unique trees - they are the largest single-stem trees in the world and some of the oldest living beings in the world with proven age of 3,500 years. These trees grow in small area - on the western slopes of Sierra Nevada mountains in California.

In order to propagate these trees need regular wildfire, thus in 1970 in this area started controlled burns.

History

Boole tree by far is the largest tree in Converse Basin grove of giant sequoias. Earlier this forest was magnificent, with thousands of magnificent sequoias in it, but in 1892 - 1918 here were cut most of the giant trees and now some 60 - 100 large trees remain.

Tree got its name sometimes around 1895, when Fresno doctor A.H.Sweeny honoured the feat of the supervisor of logging operations Franklin A. Boole - this man saved the tree from felling due to its giant size.

Until 1931 this tree frequently was named as the largest tree in the world, just like another giant - General Grant Tree. Now General Grant Tree is the second largest and Boole Tree - sixth largest sequoia.

Dimensions

Boole Tree by all accounts is one of the largest trees in the world. Especially impressive is its girth at the ground level - 34.4 m. Further up it becomes thinner and at the height of 1.37 m the girth is 24.3 m (1). There are sequoias with larger circumference, e.g. General Grant Tree.

The height also is beyond impressive - 81.9 m and calculated volume of its trunk is 1,203 m³.

It is amazing that the trunk of this tree and its dead branches are seen even on the satellite images on Google Earth.
