Establishing native vegetation communities on roadsides can be a proactive approach to sustainable roadways. Revegetation with native species is the preferred management practice on Idaho roadways. The environmental and economic benefits of increasing desirable vegetation along Idaho roadways include: improving slope stabilization, soil conservation, roadway safety while reducing erosion, roadside maintenance costs and noxious weeds in right-of-ways. Selecting appropriate plant species for revegetation is the foundation for successful roadside revegetation. This research was an extension of an original project conducted by Dr. James Kingery and others. This extension collected an additional two years of data from the previously established research project sites as well as collected data from other new Idaho Transportation Department (ITD) roadside reclamation projects that used native plant seedings. The combination of the information will help ITD address specific revegetation requirements and determine the most effective ways to provide for the long-term establishment of desirable perennial native vegetation as well as reduce surface erosion and weed establishment.
