Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 363: Control of Invasive Species explores the extent to which state departments of transportation are identifying actions that affect the spread of invasive species, preventing introduction, tracking status and locations of "invasives" in a timely and ongoing manner, controlling found populations, restoring invaded habitats, conducting research, and sharing lessons learned. The report documents successful practices and lessons learned. It also synthesizes the state of the practice in developing Integrated (Roadside) Vegetation Management, along with physical, chemical, biological, and cultural control mechanisms.
