Beech trees are dominating the woodlands of the northeastern United States as the climate changes, and that could be bad news for the forests and people who work in them, according to a group of scientists.

The scientists say the move toward beech-heavy forests is associated with higher temperatures and precipitation. They say their 30-year study, published in the peer-reviewed Journal of Applied Ecology, is one of the first to look at such broad changes over a long time period in the northeastern U.S. and southeastern Canada.

Changes - Ramifications - Forest - Ecosystems - Industries

The changes could have major negative ramifications for forest ecosystems and industries that rely on them, said Dr. Aaron Weiskittel, a University of Maine associate professor of forest biometrics and modeling and one of the authors.

Beech, often used for firewood, is of much less commercial value than some species of birch and maple trees that can be used to make furniture and flooring.

Answer - One - Lot - People - Heads

"There's no easy answer to this one. It has a lot of people scratching their heads," Weiskittel said. "Future conditions seem to be favoring the beech, and managers are going to have to find a good solution to fix it."

The authors of the study, who are from the University of Maine and Purdue University, used U.S. Forest Service data from 1983 to 2014 from the states of Maine, New Hampshire, New York and Vermont to track trends in forest composition. They found that abundance of American beech increased substantially, while species including sugar maple, red maple and birch all decreased.

That's a problem not only because...
