Chemical and Mechanical Control of False Hellebore ('Veratrum californicum') inan Alpine Community

摘要

Herbicide and mechanical control treatments for false hellebore (VeratrumCalifornicum) 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 distrupted; however, the esuing plant communities had a high density of weeds. Several herbicides also effectively controlled false hellebore, with fewer weeds in the understory afterward.
