TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 341: Integrated Roadside Vegetation Management examines the incorporation of integrated roadside vegetation management decision-making processes into highway project planning, design, construction, and maintenance. The report also documents existing roadside vegetation management research and practice.
Originally published by the U.S. Department of Transportation's Federal Highway Administration (FHWA), Office of Natural Environment to promote the planting and care of native plants along highway rights-of-way, this unique handbook provides managers of roadsides and adjacent lands with the information and background they need to make site-specific decisions about what kinds of native plants to use, and addresses basic techniques and misconceptions about using native plants. It brings together in a single volume a vast array of detailed information that has, until now, been scattered and difficult to find.The book opens with eighteen short essays on principles of ecological restoration and management from leading experts in the field including Reed F. Noss, J. Baird Callicott, Peggy Olwell, and Evelyn Howell. Following that is the heart of the book, more than 500 pages of comprehensive state-by-state listings that offer: a color map for each state with natural vegetations zones clearly marked comprehensive lists of native plants, broken down by type of plant (grasses, forbs, trees, etc.) and including both scientific and common names, with each list having been verified for completeness and accuracy by the state's natural heritage program contact names, addresses, and phone numbers for obtaining current information on invasive and noxious species to be avoided resources for more information, including contact names and addresses for local experts in each state The appendix adds definitions, bibliography, and policy citations to clarify any debates about the purpose and the direction of the use of native plants on roadsides.Roadside Use of Native Plants is a one-of-a-kind reference whose utility extends far beyond the roadside, offering a toolbox for a new aesthetic that can be applied to all kinds of public and private land. It can help lead the way to a cost-effective ecological approach to managing human-designed landscapes, and is an essential book for anyone interested in establishing or restoring native vegetation.

All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.
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.
