Jonah Goldberg's got an interesting column today.

...forests are breaking out all over America. New England has more forests since the Civil War. In 1880, New York State was only 25 percent forested. Today it is more than 66 percent. In 1850, Vermont was only 35 percent forested. Now it's 76 percent forested and rising. In the South, more land is covered by forest than at any time in the last century. In 1936 a study found that 80 percent of piedmont Georgia was without trees. Today nearly 70 percent of the state is forested. In the last decade alone, America has added more than 10 million acres of forestland.
