Long-Term Impacts of the Hemlock Woolly Adelgid on Forest Carbon at Harvard Forest 2008-2011

This study used a comparative approach to study potential changes in C fluxes and storage and N cycling associated with Hemlock Wooly Adelgid induced hemlock decline and replacement. The stands include primary and secondary growth hemlock forests (230 and 132 years old, respectively), recently disturbed stands (5 and 18 years old) that now have rapidly growing black birch saplings, and a mature black birch stand of age similar to the second-growth hemlock stand.
