Approximately one-third to slightly over 40% of North America is covered by forests. Estimates vary depending on the source and definitions used:

• About 32.7% of total North America is forested, equivalent to roughly 677 million hectares

• Another source estimates forest and other wooded land covers approximately 850 million hectares, slightly more than 40% of the total land area of North America. Of this, forests alone account for about 500 million hectares or 25% of the land area, with the remainder being other wooded land such as open woodland and shrubland

• In the United States specifically, forest cover is around 34-36% of the land area, with some regional variation

• Canada accounts for about half of North America's forest cover, with nearly 45% of its land area forested

In summary, roughly one-third to just over 40% of North America is forested, with the figure depending on whether other wooded lands are included and the specific definitions applied
