Herbicide and mechanical control treatments for false hellebore ( Veratrum californicum 

 Durand) were applied in the early 1980's at an alpine site in central Utah. Periodic data 

 collection through 1991 indicated the treatments' relative effectiveness. The 1991 data also 

 evaluated natural recovery of the understory plant community. Mechanical treatments were 

 most effective when the rhizome was disrupted; however, the ensuing plant communities 

 had a high density of weeds. Several herbicides also effectively controlled false hellebore, 

 with fewer weeds in the understory afterward. 



KEYWORDS: herbicides, weed control, mechanical methods, hand cutting, rotary
