Invasive Species and Noxious Weeds

Managing vegetation along highways presents a serious challenge in preserving natural beauty along travel corridors and preventing the spread of invasive species.

Invasive Species – Invasive species have the potential to affect a wide range of human and natural activities and functions. Highways present an ideal path for species to spread out of their native environment. FHWA provides guidance and information resources to transportation and planning agencies in order to prevent the problems associated with native species.

For questions regarding roadside vegetation issues in a particular State, please refer to the list of Roadside Vegetation Contacts.
