First and foremost, thank you to the WAB 2010 Coordinating Committee members, and Liz Galli-Noble and Emily Rindos of the Center for Invasive Plant Management for taking on the challenge of organizing the 2010 conference. WAB 2010 would also not have been possible without the generous support of our sponsors. A very special thank you to Bonnie Harper-Lore, who helped ensure continued financial support for WAB, including WAB 2010, from the US Federal Highway Administration (FHWA). We are also grate- ful to: Gina Ramos and the Bureau of Land Management for matching the FHWA’s support for WAB 2010; the US Fish and Wildlife Service for providing event leadership and administrative support; and the Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) for providing crucial organizational, financial, and administrative support over the years.
