Summer Student Publishes Invasive Species Research

Jenna Turner and her mentor Matt Fitzpatrick

2009 Harvard Forest Summer Research Program student Jenna Turner has co-authored a paper using her summer project data. Using fluorescent powder, she and mentor Matt Fitzpatrick simulated the dispersal of an invasive insect (the hemlock woolly adelgid) in a hemlock forest understory. The clumps of powder, which are larger than the insect but easier to detect in the forest understory, generally

Expanding Research on the Impacts of Deer and Moose

Using horses for scientific research at Simes

Four new pairs of deer and moose fence exclosures have been constructed in mature oak and hemlock stands at the Forest. These new undisturbed sites complement existing exclosures built in recently logged stands at Harvard Forest, on DCR Watershed Land, and in Northern CT. The study, led by Highstead ecologist Ed Faison and Steve DeStefano of the Mass. Cooperative Fish
