Invasive species such as buckthorn, honeysuckle, and garlic mustard are expected to become more problematic in coastal oak-pine hardwood forests under climate change.

There are many invasive plant species, insect pests, and forest diseases that have negative impacts on oak-pine hardwood forests, many of which are expected to increase through the direct and indirect effects of climate change. Invasive species such as buckthorn, honeysuckle, and garlic mustard are existing threats to these forests, and invasive species are expected to increase in abundance under climate change, particularly where forests are disturbed.
