U.S. quickly losing trees

The United States lost more than 46,000 square miles of forest from 2000-2005

Out of seven of the most heavily forested nations on Earth, the United States experienced a greater percentage of forest loss from 2000 to 2005 than did any of the other countries, according to a study by Matthew Hansen of South Dakota State University.
The one part of the contiguous USA that experienced the most forest loss was the Southeast, a large chunk of which lost more than 10% of its forest cover from 2000 to 2005, the year for which the most recent data were available.
Hansen points out that the forest loss in the USA isn't necessarily permanent: "This does not mean that (the forests) do not regenerate, and we make no statements whatsoever about sustainability," he said. "But, compared to other regions of the world, a lot is going on."
