Insect pests like the emerald ash borer may have negative impacts on Floodplain Forests.

Longer growing seasons and milder winters might allow populations of native forest pests to build more rapidly, and many pests have been shown to be more damaging when interacting with trees that are already stressed due to droughts or other impacts. It also seems very likely that the emerald ash borer will reduce the amount of green and black ash in northern Minnesota.
