摘要：	Transportation agencies manage approximately 12 million acres of land in transportation rights-of-way. Vegetation management therefore is a primary activity of department of transportation (DOT) maintenance forces in all 50 states, Puerto Rico, and the District of Columbia, as well as for local highway departments across the country. Vegetation management can involve significant department staff and staff time, and the battle against invasive species and their effects on the aesthetic and natural environments is requiring increasing time and resources. Vegetation management affects transportation systems, public health, the economy, and natural environments. As transportation corridors for plant and animal invasives carried by traveling vehicles, highways cross geologic barriers that previously prevented the spread of species. Consequently, transportation corridors are a factor in the spread of and loss of natural habitat, the top two drivers of declining biodiversity. Increased species rarity has been a concern to other agency partners and stakeholders. These pressures and Executive Order 13112, which directs all federal agencies to address invasive species concerns and refrain from actions likely to increase invasive species problems, have made a synthesis of existing practice for controlling invasive species more urgent than ever before.
