It is highly probable that the negative impact of English ivy (Hedera helix) on VA forests meets or exceeds that of all the other listed species. It takes over woodlands, killing all of the understory vegetation and climbing the trees, which it proceeds to suffocate. It is universally awful in the state. Whereas kudzu takes over edge habitat, English Ivy kills the forest from within.

The fact that this species  is still being sold in nurseries is a travesty, and it produces nothing for its purchasers except aesthetics and problems.

Also add Ligustrum sinense (Chinese privet) and Ligustrum lucidum (glossy privet), which are a growing problem.
