Abstract

This study had two goals: first, to establish a need to use native plant materials for planting and revegetation of highway right of ways in Utah; and secondly, to develop a list of potential native plants sui table for hi.ghway planting in Utah. To accomplish these two goals, three steps were completed. Correspondence was exchanged with officials of other state highway departments to determine their attitudes concerning the use of native plants for highway planting. Second, a case study was completed on two sections of the Interstate Highway system in the Weber-Davis area of Utah. This was done to document the present planting practices of the Utah Department of Transportation. The survival rate of the plants planted by Utah Department of Transportation was determined to be moderate to low, while native species have revegetated and were surviving without special maintenance. It was determined that there was a need to utilize native plants for highway planting in Utah. Third, a list of native plants was developed to provide a potential list of species suitable for highway planting and revegetation.
