         General Impact

    Oplismenus hirtellus ssp. undulatifolius spreads rapidly through wooded natural areas and disturbed environments. It may crowd out native herbaceous plants, and seems to prevent regeneration of native hardwood tree species. It has displaced native species in several locations of both Maryland and Virginia and may alter environments (Westbrooks & Imlay, 2009).
