Ecosystem and Vegetation Management
Plants and Invasive Species
Managing vegetation along highways presents a serious challenge in preserving natural beauty along travel corridors and preventing the spread of invasive
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.
Roadside Vegetation – What was once the FHWA Wildflower Program has evolved into a holistic roadside program. Roadside rights-of-way account for
more than 10 million acres of land in the United States. This land requires care that assures water quality, improves erosion control, increases wildlife
habitat, reduces mowing and spraying, enhances natural beauty, and protects natural heritage. The FHWA Roadside Vegetation Program serves as a technical
resource for this care of the land.
- "Roadside Use of Native Plants" – This glove-compartment size handbook is a reference for those who
restore, design, or manage native plants. Its State by State organization of information is a beginning point in decision-making. To make site by site
decisions within a State, local expertise will be necessary. This information is aimed at preserving the native remnants that still exist and restoring
natural heritage where necessary. Hardcopy versions of the handbook are available online through
Island Press or by calling (800) 828-1302.
- Wildflowers – Overview of the use of wildflowers as roadside vegetation.
- "Greener Roadsides" – Archived issues of FHWA's quarterly newsletter about vegetation management
- Vegetation Management: An Ecoregional Approach – This publication marks the third and final installment of an FHWA guidebook series
on managing roadside ecology. It was designed as a quick-start guide for maintenance staff from State DOTs, as well as landscape, environmental services,
and erosion control personnel.
