Woodpeckers and the Human Impact
One can find many seasonal or vernal pools throughout the College Sanctuary south of College Street and west of South East Street. They typically hold breeding populations of wood frogs, spring peepers, and various salamanders. Woodpecker excavations in trees throughout the Sanctuary woods are evidence of several species at work, including pileated, hairy, and downy woodpeckers. To spot woodpecker damage, look for the closely-packed rows of holes they make searching for insect larvae beneath the surface of the tree bark.
