    Description

    The Hubbard Brook Ecosystem Study presents a unique opportunity for studying long-term ecosystem responses to changes in anthropogenic factors. Following industrialisation and the intensification of agriculture, the Hubbard Brook Experimental Forest (HBEF) has been subject to increased loads of atmospheric deposition, particularly sulfur and nitrogen. The deposition of these elements, also referred to as acidic deposition because of its acidifying effect on the soil, has inevitably affected the forest ecosystem and streams at HBEF. A particular characteristic of great relevance for studying the effects of acidic deposition at HBEF is the existence of long time-series of field measurements, including forest biomass, soil and runoff water. This study builds on the available data for HBEF to validate the dynamic ecosystem model ForSAFE, with the aim of using the model to reconstruct the historical state of the forest as it has been gradually affected by the increasing atmospheric deposition, and to make future predictions about changes in the forest ecosystem at HBEF.
