Eastern hemlock, a species with key ecological roles in eastern forests, is being killed throughout its range by an invasive insect, the hemlock woolly adelgid (HWA). Recently, Forest Service scientists and their partners conducted a study in which they subjected potted hemlock seedlings to different levels of artificial shade and infested them with HWA. The results, published in the journal Forest Ecology and Management, showed that elevated sunlight levels improved hemlock growth and carbon status and dramatically reduced numbers of HWA on the branches. The findings suggest that forest management practices, such as thinning or creating small canopy gaps, that increase sunlight exposure on hemlocks could be valuable tools in the effort to manage and conserve eastern hemlock. Additional research to test the effect of such practices on the health of hemlocks growing naturally in the forest is ongoing. The research is ongoing, and aims to provide forest managers with additional strategies for protecting hemlock trees.
