UNH Forest Program Notices Pine Needle Loss
02/25/2013 12:46 PM ET  

Barrett Rock of UNH's Institute for the Study of Earth, Oceans and Space, says something very serious is stressing the trees.

DURHAM, N.H. (AP) _ A University of New Hampshire forest program has noticed that white pine trees in northern New England seem to be losing more needles lately.

The Forest Watch program says the trees maintained vigorous growth during the late 1990s as the Clean Air Act took effect and ozone levels fell.

But data shows that since 2010, the trees have not done a good job of retaining those needles.

Barrett Rock of UNH's Institute for the Study of Earth, Oceans and Space, says something very serious is stressing the trees. Possible causes are air pollution from wildfires and unusually wet weather that's caused an explosion of fungi.

Forest Watch is an inquiry-based science program that takes K-12 students and teachers out of their classrooms to study air pollution and forest health.
