Determining the Health of New England Forests

Forest Watch

Bridging Science and Education Through Ground-Truth Studies of White Pine Stands

Forest Watch offers students and teachers authentic opportunities in science by participating

in on-going research to assess the health of forests in New England.

Schools set-up permanent sampling plots and conduct several ecological and biophysical

measurements in white pine stands, looking for signs of ground-level ozone damage and other

forest health concerns.

Getting samples from top of trees

Sample collection

White pine branches are cut from the north and south sides of each tree

for lab analysis and spectral analysis

Fascicles are removed for identification of ozone

symptoms on the needles (white pine has fascicles of

five needles)
