AASHTO GVM-1APP contains the appendices to the Guidelines for Vegetation Management published by AASHTO in 2011. The volume is issued separately and contains only the appendices for the publication, not the main text. The appendices supply supporting reference material for the vegetation management guidance presented in the companion main volume. The guidelines as a whole address the conditions roadside vegetation managers face, including dwindling resources, increasing environmental and legal constraints, and public pressure to provide safe and aesthetically pleasing roadsides. Readers should use this appendix volume together with the main text, which is available separately. Roadside vegetation managers in state and local agencies are the intended audience for the complete publication.
