Overview: The Hubbard Brook Experimental Forest (HBEF) is a 3,160 hectare reserve located in the White Mountain National Forest operated by the USDA Forest Service, near Woodstock, New Hampshire. The on-site research program is dedicated to the long-term study of forest and associated aquatic ecosystems. It has produced some of the most extensive and longest continuous data bases on the hydrology, biology, geology and chemistry of a forest and its associated aquatic ecosystems. Hubbard Brook scientists discovered acid rain in North America by taking meticulous, long-term measurements of rain and snow. Scientists continue to document acid rain’s damaging effects and track recovery linked to pollution reduction efforts.
History: The HBEF was established by the USDA Forest Service, Northeastern Research Station in 1955 as a major center for hydrologic research in New England. In the early 1960’s, Dr. F. Herbert Bormann and others proposed the use of small watersheds to study element cycling. In 1963, the Hubbard Brook Ecosystem Study (HBES) was initiated by Bormann and Drs. Gene E. Likens and Noye M. Johnson, then on the faculty of Dartmouth College, and Dr. Robert S. Pierce of the USDA Forest Service. They proposed to use the small watershed approach at Hubbard Brook to study linkages between hydrologic and nutrient flux and cycling in response to natural and human disturbances, such as air pollution, forest cutting, land-use changes, increases in insect populations and climatic factors.
Research Topics: Vegetation structure and production; dynamics of detritus in terrestrial and aquatic ecosystems; atmosphere-terrestrial-aquatic ecosystem linkages; heterotroph population dynamics; effects of human activities on ecosystems.
