Scientists at Michigan State University have shown that streams can be key health indicators of a region’s landscape, but the way they’re being monitored can be improved.
New research featured in Ecology Letters showcases how streams can be used as sensors to diagnose a watershed’s sensitivity or resiliency to changes in land use practices, including the long-term use of fertilizers. Using streams as sensors – specifically, near the headwaters – can allow scientists, land-use managers and farmers to diagnose which watersheds can be more sustainably developed for food production, said Jay Zarnetske, MSU earth and environmental scientist and co-author of the study.

“We were surprised to see that the streams were good sensors of long-term nutrient conditions,” he said. “Our methods show that we can learn much from a relatively small number of samples if they are collected more strategically than current watershed management practices dictate. This understanding is critical in protecting aquatic ecosystems and ensuring human water security.”
