Invasive Plant Resources by Claudette Sims
Invasive Plants and Wildlife
Many invasive plants cannot be used by wildlife for food which puts grazing pressure on the few native plants that remain. Invasive plants also pose threats to agriculture due to their ability to spread quickly, out-compete crop and forest plants, and deteriorate soil quality. Once they have taken hold, the thick spread of invasive plants makes them costly and time-consuming to remove.
Invasive Plant Removal
General information
Work in moist soil where possible; prioritize removing flowers to prevent seed formation; cut repeatedly at ground level; dig out entire plant and all roots; work on the invasive front first.
