Ecosystem and Vegetation Management
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.
- Invasive Species Cover And Wildlife Use at Compensatory Mitigation Sites – This FHWA Study evaluates compliance
with invasive species performance standards at state Department of Transportation (DOT) wetland mitigation sites by comparing invasive species cover and
wildlife use at eight DOT mitigation sites and eight corresponding reference sites.
- Executive Order - Safeguarding the Nation from the Impacts of Invasive Species
- Field Guide to Common Roadside Invasive Species – This FHWA Field Guide identifies common
roadside invasive grasses and forbs that appear on State noxious weed lists.
- National Invasive Species Information Center – This U.S. Department of Agriculture
(USDA) site provides information about invasive species for Federal, State, local, and international sources.
- Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) – As a formal partnership between sixteen Federal agencies, FICMNEW holds the responsibilities to manage and regulate
invasive species across the United States.
- "Dangerous Travelers: Controlling Invasive Plants Along America's Roadways" – As part of its efforts to prevent the spread of invasive species, the USDA Forest Service San Dimas Technology and Development Center, in partnership with the National Forest System Invasive Species Program, the Federal Highway Administration, the U.S. Department of the Interior Fish and Wildlife Service, and the Pennsylvania Department of Transportation, has produced a training video designed to help road maintenance crews recognize and control invasive flora. The video may be accessed online or by contacting:

- "Invasive Plants: What are they and how can we pull together to win the war on weeds!" – Presentation available for
PowerPoint (7.5 MB) or in HTML.
