Native Plant Establishment Success Influenced By Centaurea Stoebe Control Method, Laurelin Marie Martin

Masters Theses

Invasive species frequently hinder restoration efforts. While the effectiveness of differing control methods are often reported, the impacts these methods have on the establishment of a native plant community are often unknown. To determine methods that effectively reduce spotted knapweed (Centaurea stoebe) while enhancing native species establishment, we tested 12 treatment combinations consisting of an initial site preparation (mowing, mowing + clopyralid, or mowing + glyphosate), with combinations of annual adult knapweed hand pulling, and/or burning. We established 48 plots and applied site preparation treatments during summer 2008, seeded 23 native forbs and grasses during spring 2009, pulled …
