Giant sequoias by far are the largest trees of the world by wood volume. But they belong also to the highest trees of the world – there is known 95.8 m tall specimen.

Redwood Mountain Grove is the largest stand of this tree, its area is 1,240 ha. It is assessed that here grow some 15,800 sequoias. Most prominent sequoias have their own names and in Redwood Mountain Grove are located two such named trees which belong to 25 largest trees by volume in the world – The Hart Tree and Roosevelt Tree.

Here is located one of the tallest known sequoias – it was discovered in July 1998 and measured in August 1998 by Michael Taylor, the height then was 94.9 m. In July 2005 there was done repeated measurement by redwood researcher Steve Sillett – the result was exactly the same.

The main trunk of this tree was killed by a fire at the height of 74.4 m and there grew new trunks, reaching current height.

This tree has not received any specific name and its exact location is not given in the available works. Close to it grow several slightly lower sequoias.

This was considered to be the tallest giant sequoia in the world but in 2013 there was reported an even taller tree – 95.8 m tall tree, here named: Tallest Giant Sequoia in Converse Basin.

There have been reports about higher – up to 97.8 m tall sequoias and even (wrong) assumptions that these trees could reach 133 m height ("Father of the Forest" in Calaveras Grove mentioned by James M.Hutchings, Scenes of Wonder and Curiosity in California in 1862).

Although California is one of states in the United States of America, Americans often compare it to a separate country, e.g. “if California would be a country, it would have the eighth largest economy in the world”. We can go on with this comparison – California has more landmarks and attractions than many large countries of the world.

Category includes some of the most impressive and interesting separate trees of the the world. Total number of tree species in the world still is a wild guess – may be 10,000 and may be 100,000 but most likely somewhere in between. Every month there are reported new tree species from the whole world, including the Western Europe.
