“There are many species of plants and animals that spend most or all of their lives in small waterways and tributaries, including local species of concern like the Tennessee dace. In order to intelligently manage these systems, we need to have details and accurate assessments of the area’s environmental suitability and the distribution of important habitat features. My research involved developing a system for mapping small stream habitats that are generally difficult to study using traditional techniques, such as satellite and aerial photography.”


“I have been turning over rocks and stomping around creeks since I was a child, and I’ve never really grown out of that urge to seek out and understand things that are wild and new. This research was an opportunity to professionally pursue that urge in a new context—most of my experience in ecology thus far has been entirely terrestrial; this provided me an opportunity to quite literally get my feet wet in aquatic research.”


“This project has broadened my range of skills and experience considerably. It’s very valuable to have been able to work on a project from its very beginning stages, going from designing and budgeting to assembling and testing equipment. Planning will be an essential skill for any research project I lead in the future.”
