Direct damage from the insect is causing gradual mortality of hemlock. Widespread harvesting of hemlock in advance of mortality, in contrast, causes immediate mortality and removal of biomass from the site. Although both processes affect thousands of acres of forest annually, we have only a limited understanding of their effects on forest ecosystem function and productivity and the nature of the subsequent forest community. We anticipate that harvesting will yield different consequences than gradual mortality from the insect. Therefore we designed an experiment to simulate these contrasting impacts, by logging or girdling hemlock stands. Results from the experimental treatments are compared to the changes observed in forests that are being infested by the adelgid, and can also be included in integrated analyses of a suite of large experiments that form a core component of the Harvard Forest LTER programForest Ecosystem Monitoring CooperativeEmeryBooseprincipalInvestigatorSince 1907, the Harvard Forest has served as a center for research and education in forest biology and conservation. The Forest's Long Term Ecological Research (LTER) program, established in 1988 and funded by the National Science Foundation, provides a framework for much of this activity.Understory Vegetation in Hemlock Removal Experiment at Harvard Forest since 2003Hemlock decline in New England is caused by direct and indirect effects of invasion of the hemlock woolly adelgid.
