2008-2009: Control of Woody Invasive Shrubs

Biology 243 students and two students involved in summer research projects conducted field research over a three-year period and determined three factors should be considered to enhance greatly the likelihood that woody invasive shrubs can be successfully removed as part of a restoration project.  Roundup herbicide (glyphosate) should be painted on the cut stumps of mature plants in its concentrated form (at least 41% active ingredient), within 20-minutes of cutting the top off, and in reasonably dry soils.  Accounting for these three factors should ensure a greater than 98% rate of control.
