Studies have been conducted in and around the Penobscot Experimental Forest in Bradley, Maine from 1995 through the present in order to investigate the role of forest management practices on insect biological diversity as well as forest function. In general, sampling and taxonomic challenges have seriously limited the scope of many studies of this type. The use of "morphospecies" may well provide insights into the determination of those taxonomic groups that are sensitive to forest management. However, it may not be adequate for illuminating the biological mechanisms by which forest management impacts those species. Studies such as ours illustrate the need for basic taxonomic and biological investigations which can be used to understand and evaluate the impacts of harvesting activities.
