DOIAbstract
Most research on dynamics and impacts of plant invasions has evaluated patterns and effects over brief time periods (i.e. <4 years). As such, little is known about the persistence of invasions and their long-term impacts on native species. To experimentally evaluate longer-term effects of invasions, we established field plots with native tree and herbaceous species and then invaded half of the plots with the most widespread invasive grass in the eastern United States (Microstegium vimineum). Over 8 years, we quantified invader and native plant biomass, native plant diversity, and tree density and size. Microstegium was dominant during the first 4 years of the experiment, constituting more than 60% of herbaceous plant...
