Abstract
  • Himalaya blackberry (Rubus armeniacus) is a widespread, exotic, invasive plant now common over much of western Oregon and Washington. An observational experiment revealed that disturbance to a monoculture of Himalaya blackberry allows the soil seed bank to be expressed and return the inhabited area to an earlier successional stage. This stage of succession may be more manageable and closer to a desirable vegetative condition than Himalaya blackberry. A splitplot experiment that imposed the effects of plowing and herbicide application after mowing, as well as shade treatments at different levels, indicated that each treatment, separately and together, effectively inhibit the regrowth of Himalaya blackberry. These results provide a framework for managing large areas inhabited by Himalaya blackberry.
