• Abstract:
  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 report provides practical information for improving ; roadway revegetation in Idaho. The overall objective was to monitor vegetation and soil attributes to determine effective means ; for establishing perennial native vegetation, reducing surface erosion, and preventing weed encroachment. The results provide ; guidance and recommendations on species selection, seeding methods and site preparation techniques. Bluebunch wheatgrass ; and Idaho fescue were the best performing grasses. Grass species that consistently establish where seeded but have a low ; canopy cover include sheep fescue, western wheatgrass, and basin wildrye. Forbs and shrub species had low establishment ; success rates and low percent canopy cover on roadside revegetation projects. If forbs are desired, it is recommended to use ; species that are known to establish well, relatively inexpensive, and tolerant of the herbicides being applied to control weeds.
