Impacts of Nonnative Invasive Species on US Forests and Recommendations for Policy and Management

摘要

The introduction of normative invasive species (NNIS) into the United States has had tremendous impacts on the nation's commercial and urban forest resources. Of principal concern are the effects of NNIS on forest composition, structure, function, productivity, and patterns of carbon sequestration. In 2006, the Society of American Foresters commissioned an ad hoc team to prepare a white paper on the effect of NNIS on America's forests. The paper was the genesis of this article, which provides an overview of the impacts of NNIS within the United States and includes recommendations for NNIS policy and management.
