Pitch pines are so named because of their sticky sap that may discourage some predators, like the unlucky Thoreau.
With a grant from the National Park Service's National Center for Preservation Technology and Training, Nick Smith, an assistant professor in Texas Tech University's Department of Biological Sciences, and researcher Jeff Licht from the University of Massachusetts-Boston are beginning important research to determine whether the Concord pitch pines' defense mechanisms can fend off a far more ominous threat, the southern pine beetle.
