Forests that Govern

The critical role that forests play in providing stable flows of pure water was demonstrated in pioneering research at Hubbard Brook. Long-term studies by HBR scientists have clarified the mechanisms underlying these and other forest ecosystem services thereby providing the basis for projecting the social benefits from environmental policies.

A classic experiment at HBR involved the deforestation (shaded) of watershed 2 (dashed line) which resulted in striking increases in the flux of key nutrients in comparison with the reference watershed 6.
