The goal of this Third Edition is to update long-term data presented in earlier editions and to generate new syntheses and conclusions about the biogeochemistry of the Hubbard Brook Valley based on these longer-term data. There have been many changes, revelations, and exciting new insights generated from the longer data records. For example, the impact of acid rain peaked during the period of the HBES and is now declining. The longer-term data also posed challenges in that very marked changes in fluxes occurred in some components, such as hydrogen ion and sulfate deposition, calcium and nitrate export in stream water and biomass accumulation, during the almost 50 years of record. Thus, presenting “mean” or “average” conditions for many components for such a long period, when change was so prominent, do not make sense. In some cases, pentads or decades of time are compared to show these changes in a more smoothed and rational way for this long period. In some cases, a single period, often during periods of rapid change, such as acidification, is used to illustrate the main point(s). And, for some elements a unique mass balance approach, allowing the calculation of the Net Ecosystem Flux (NEF), is shown on an annual basis throughout the study.

Dr. Likens' research focuses on the ecology and biogeochemistry of forest and aquatic ecosystems, primarily through long-term studies at the Hubbard Brook Experimental Forest, in the White Mountains of New Hampshire. He was the co-founder of the Hubbard Brook Ecosystem Study in 1963, which has shed light on critical links between ecosystem function and land-use practices. He and his colleagues were the first scientists to discover acid rain in North America and to document the link between the combustion of fossil fuels and an increase in the acidity of precipitation. His findings have influenced politicians and policy makers, guided and motivated scientific studies, and increased public awareness of human-accelerated environmental change.

Reviews for Biogeochemistry of a Forested Ecosystem

From the book reviews: This third edition ... continues the release of data and interpretations related to the Hubbard Brook Experimental Forest (HBEF) in New Hampshire. ... The HBEF system is a well-circumscribed site, providing a detailed large-scale area where changes in the availability, cycling, and fluxes of chemical elements and other matter can be monitored. ... Summing Up: Recommended. Upper-division undergraduates and above. (D. H. Pfister, Choice, Vol. 51 (11), July, 2014)
