Watersheds as Laboratories

Hubbard Brook scientists pioneered the small watershed approach, which transformed the study of forests by using whole watersheds as living laboratories. This ground-breaking approach fostered many new discoveries beneficial to both science and society.

Long-term trends in annual precipitation, stream discharge, and evapotranspiration (ET) for watershed 3 at the Hubbard Brook Experimental Forest. There has been a significant long-term increase in annual precipitation and stream runoff and a significant decrease in evapotranspiration.
Data are from U.S. Forest Service, J. Campbell.
