about five years ago, scientists said, and they decided to take a closer look. The researchers examined 658 red spruce trees in 52 plots in Vermont, New Hampshire, New York, Massachusetts and Maine. They found that 75 percent of the trees and 90 percent of the plots showed increasing growth since 2001. They credit cleaner air and a warming climate that
extended the growing season.
"Higher temperatures help some species and hurt others — right now,
red spruce are benefiting, but they could be vulnerable to change in the future," Schaberg said.
Similar trends are emerging in the Appalachian Mountains in West Vir- ginia, which were also hit by acid rain, according to a recent report in the Global Change Biology journal.
The two studies provide further evidence that addressing causes of acid rain helped the species recover, said Timothy Fahey, a forest ecologist and professor at Cornell University.
That recovery should help efforts to restore red spruce forests to moun- tains in central Appalachia, where they were heavily logged in the late 1800s and early 1900s, reducing the habitat for the now-endangered Car- olina northern flying squirrel.
Last month in Vermont, Schaberg was hiking through the woods on Mount Mansfield, Vermont's highest peak, with Alexandra Kosiba, lead researcher for their study in the journal Science of the Total Environment. They found red spruce at middle elevations and higher that were thriving. The trees were surrounded by saplings, and seed-bearing cones lay on the ground.
"This is a good sign that the species is doing well in the near term, and then the future forests will have red spruce," said Kosiba, a staff scientist for the Forest Ecosystem Monitoring Cooperative at the University of Vermont.

Kosiba led a study that found that the red spruce, once heavily damaged by acid rain, is rebounding in five Northeast states.
