AASHTO GVM-1 contains the main text of the Guidelines for Vegetation Management published by AASHTO in 2011, issued without the appendices, which are available separately. The guidelines draw on the long-term experience and expertise of roadside vegetation managers to provide the basic knowledge required for managing highway roadsides. They respond to dwindling resources, increasing environmental and legal constraints, and public pressure to provide safe and aesthetically pleasing roadsides. The preview shows the main text beginning with Chapter 1, an introduction to the guidelines. Because vegetation managers throughout the United States and worldwide face similar challenges and opportunities, the guidelines present practices of broad applicability. Roadside vegetation managers in state and local agencies can use the main text together with the separately issued appendix volume.
