Comparing effectiveness and impacts of Japanese barberry (Berberis thunbergii DC) control treatments and herbivory on plant communities JS Ward, SC Williams, TE Worthley - Invasive Plant Science and Management, 2013

Two factors that can degrade native plant community composition and structure, and hinder restoration efforts, are invasive species and chronic overbrowsing by ungulates such as white-tailed deer. Beginning in 2007, the effectiveness, costs, and impacts of Japanese barberry control treatments and herbivory on non-native and native plant communities was examined ...  recovery of native communities will require more than simply removing the dominant invasive species where deer densities are high. Excellent reduction of Japanese barberry cover can be achieved using either directed heating or herbicides as follow-up treatments in a two-step process, but other invasive plants may become a problem when barberry is removed if deer populations are low.
