Concerns continue over potential impacts of elevated atmospheric nitrogen deposition on forested ecosystems of the northeastern United States and eastern Canada. Researchers have conducted numerous experiments over the last several decades to address these concerns at forest plot and watershed scales. Both individually and together, these studies contribute significantly to our understanding of the process of nitrogen saturation of forest ecosystems.

The goals of this project were to increase communication and facilitate information exchange among researchers involved in experimental nitrogen addition studies in northeastern North America and northern Europe and to analyze ecosystem response to experimentally elevated nitrogen deposition by combining results of these many studies.
