The assessment, titled "Invasive Species in Forests and Rangelands of the United States: A Comprehensive Science Synthesis for the United States Forest Sector," serves as a one-stop resource for land managers who are looking for information on the invasive species that are already affecting the landscape, the species that may threaten the landscape, and what is known about control of invasive species.
