National Research Highlights

New Insights into how Forests Provide Clean, Secure Water Supplies

Year: 2016

Forests are the source of much of our nation's water supply. Understanding how forested watersheds regulate water quality is key to proper watershed management.

“Smart Forests” Digital Environmental Sensors and Telecommunications Take Research to New Levels

Year: 2015

Scientific breakthroughs of the 21st century will be powered by tools that help researchers collect and manipulate massive datasets, visualize that data, and offer new ways of understanding the scientific processes behind that information. Forest Service scientists are taking a lead in developing a national Experimental Forests and Ranges “Smart Forests” Network. This network of wired forests uses digital environmental sensors, wireless communications, and new data visualization programs to create a powerful integrated research and monitoring program for the nation’s air, water, forest and rangeland resources.

Climate Change Effects on Streamflow

Year: 2010

In the northeastern United States, it is unclear how climate change may affect the surface water supply, which is critically important in this densely populated region. NRS scientist John Campbell and collaborators have been evaluating the impact of climate change on streamflow at small gauged watersheds at the Hubbard Brook Experimental Forest in New Hampshire.
