Abstract In the fall of 1972 and 1973, several California Department of Transportation roadcuts in the Lake Tahoe basin were stabilized as part of a highway reclamation project. Dr. Andrew T. Leiser, professor of environmental horticulture at the University of California, Davis, directed the project with the objectives of stabilizing slopes and experimenting with various reclamation techniques. Shrub species were selected for revegetation, and planted following interim stabilization measures. The present research project is a follow-up study of long-term revegetation success on the roadcuts reclaimed by Dr. Leiser in 1972 and 1973. In August, 1988, field work for this research project was undertaken to analyze the effect of some of the reclamation methods on the longterm survival of selected shrub species. Results of the research suggest that certain species may benefit from spring planting. Generally, however, certain reclamation techniques such as fertilization, the use of rock breast walls for purposes other than slope stabilization and differences in such environmental factors as amounts of solar radiation and slope length, within certain ranges, may not affect long-term survival of shrubs at this location.
