Of course this inventory contains only tree records as far as they are registered on this site. Despite the difficulties of growth and the apparent Trees with multiple trunks are excluded. Giant Sequoias. Believe it or not, the measurement was made with an extra long tape measure, but there are much easier methods you can try yourself.
