Abstract/Contents:"Vegetation is a significant safety and management responsibility for departments of transportation. Still, it is not well understood. In recent years early detection and rapid response of invasive species has become increasingly important. Only about 20 percent of departments of transportation have taken statewide inventories of invasive species and far less have took surveys of all species that occur on state roadsides. A better understanding of weed occurrences and their ecology could greatly assist with management efforts. The purpose of this study was to conduct a species survey on roadsides managed by the Mississippi Department of Transportation during 2011. Survey locations were broke down into ten physiographic regions in which 10 cross-section transects were established. Species data was collected in eight plots along each transect. For each plot (800 plots total), all species and their percent cover was recorded. Over 360 plant species were identified during the study, including both native and exotic species. Exotic species accounted for about 24 percent of the species. Tishomingo hills had the highest while the Mississippi delta had the lowest species diversity. In addition, species diversity was highest along roadside margins as opposed to plots closer to pavement. Bermudagrass (Cynodon dactylon) and bahiagrass (Paspalum notatum) had the highest mean cover statewide at 16.1 and 13.1 percent, respectively. As expected, most species correlations were negative. However, there appears to be positive correlations between at least one exotic, legume (Fabaceae) species and non-legume species that are more common near pavement. Given the magnitude of this study, this presentation only covers an overview of the data and implications regarding weed management are still being investigated."
