The current volume is 747 million acres of forest and growing in the United States. This does not include trees outside of forest areas. Inside every measurable method shows growth since 1900. Acres of trees, density of trees and board feet have all improved. About 4 million new trees are planted daily in North America for transplanting at a later date. The current definition of a forest acre is an area that is capable of growing 20 board feet of new tree each year per acre. This is not to say that it will be used as timber. This volume is twice what we considered a forest 70 years ago. Canada has even more trees. 417 million hectares is their current estimate and also growing. Mexico claims 55.3 million hectares.
