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)
