RESEARCH SUMMARY 



Eighteen species of native shrubs and forbs were planted 

 to evaluate their potential for revegetating road cuts in 

 northern Idaho and western Montana. One-year-old 

 seedlings were planted, both alone and in combination with 

 grasses and legumes, in the Coram Experimental Forest in 

 northwestern Montana. Growth, regeneration, and general 

 condition were observed 9 years after planting. 



Survival, averaged over all sites, was very good for some 

 species: Wood's rose (82 percent), red-osier dogwood (94 

 percent), and thimbleberry (73 percent). Wood's rose, bush 

 penstemon. lovely penstemon. and blackcap grew and 

 regenerated well over the 9-year period (1974 to 1983). 

 Most of the other species planted either died or did not 

 grow and develop well. All species were rated for suitability 

 based on initial survival, final survival, growth, vigor, natural 

 spread, and potential for soil stabilization. Species 

 attributes were listed for the eight highest rated species. 



Grasses and legumes provided early surface stabilization 

 while the roots of shrubs developed and provided deeper 

 soil stabilization. Study results indicate that road cuts can 

 be effectively revegetated with native shrubs. Shrub 

 survival was not reduced by grasses and legumes.
