Deciding on a research question
Becky and Chuck chose eight streams in the Park for their baseline study: four in “pristine” hemlock forests with healthy trees, and four in “impacted” hemlock forests, where the hemlock woolly adelgid left stands of dead trees. They prepared to monitor any changes in species, number, and health of macroinvertebrates in the dying hemlock forest streams that could result from changing temperatures.
