    Founded in 1963, the Hubbard Brook Ecosystem Study is one of the longest running and most comprehensive ecosystem studies in the world. The collaborative, multidisciplinary research efforts include long-term studies of air, water, soils, plants, and animals. The study site is the Hubbard Brook Experimental Forest, a 7,800-acre northern hardwood forest situated in the White Mountains of New Hampshire. The Hubbard Brook Ecosystem Study is a unique public-private partnership involving the USDA Forest Service, the National Science Foundation’s Long Term Ecological Research (LTER) program, the Hubbard Brook Research Foundation, and scientists from research institutions throughout the country.

    Data Table

    • Title: Forest Inventory of a Calcium Amended Northern Hardwood Forest 1996-2011: Watershed 1, Hubbard Brook Experimental Forest
    • Start Date: 1963-01-01
    • Description: In order to evaluate the role of Ca supply in regulating the structure and function of base-poor forest and aquatic ecosystems, the Ca content of soil was increased through the application of wollastonite (CaSiO3) in October 1999. Forest inventory surveys were initiated in 1996 and repeated at 5 year intervals. 

    • Purpose: To better understand the role of Ca supply in the regulation of structure and function of base-poor forests and aquatic ecosystems.
