What's Killing the Aspen?

By 2006, close to 150,000 acres of Colorado aspen were dead or damaged, according to aerial surveys. By the following year, the grim phenomenon had a name—"sudden aspen decline," or SAD—and the devastated acreage had more than doubled, with some 13 percent of the state's aspen showing declines. Surveys of two national forests in Arizona showed that from 2000 to 2007, lower-elevation areas lost 90 percent of their aspen.
