Among the greatest ecological challenges facing New River Gorge National River is the presence and threat of invasive species. Invasive species are those which do not naturally occur in a specific area and cause ecological and economic damage. The majority of invasive species are also exotic, or non-indigenous but some native species can become invasive too (i.e. deer in some areas). Many different organisms can become invasive pests including plants, vertebrates, invertebrates, fungi, and microorganisms. Exotic invasive species can be introduced purposely or accidentally. An intentional introduction could be a plant from Asia that is planted ornamentally in gardens and escapes. An accidental introduction could occur with contaminated containers shipped from overseas. Exotic invasive pests are successful in establishing populations on alien turf because their natural predators (disease, herbivore/carnivores) do not exist in the new territory and therefore can out-compete native species for resources. Invasive species can eliminate their native counterparts or destroy whole populations if gone unchecked.

The New River Gorge was logged extensively thoughout the past century. The landscape is now recovering, with the park ecosystem returning to its more natural state, but there are still plenty of signs of the past activities.
