Comparison and Assessment of Mechanical and Herbicide-Chemical Side-Trimming Methods of Managing Roadside Vegetation by the Texas Department of Transportation (TxDOT)

The project compared and assessed the mechanical and herbicide-chemical side-trimming methods that TxDOT uses to manage roadside vegetation. This report discusses safety, effectiveness, and economic costs of these methods. It also shares industry best management practices by appending comments of several resource professionals concerned with side-trimming operations for vegetation management on rights-of-way. The researcher based his assessment on information and data that TxDOT's Vegetation Management staff had provided, and information and perspectives on rights-of-way from resource management professionals associated with other state DOTs as well as other agencies involved in vegetation management. The report emphasized that TxDOT seeks to collaborate with stakeholders to determine the best and most appropriate side-trimming methods for various unique ecological and cultural situations across Texas.
