Numerous roadside plantings at semiarid sites in the south-central Utah counties of Juab, Sanpete, and Sevier were intended to stabilize roadsides with plants harmonizing with natural vegetation. The plantings, originally for demonstration, began in the 1950's. They included bareroot transplants and direct seedings. Soils and geologic substrates at six sites were analyzed for 15 characteristics. Plant performance and survival was summarized for 37 sites. Thirty species established well by direct seeding and 62 species established well from transplants. Numerous other species have also persisted at the planting sites but are not as vigorous or as well adapted. Direct seedings were principally grasses and forbs; the transplants were mainly shrubs. Thirty-six species showed enough recruitment to sustain themselves on the sites.
