Non-native plants are plants that have been introduced, either accidentally or deliberately, into a region where they historically did not occur. Because these plants are introduced into an environment which may lack the predators or diseases which limit their populations in their native habitat, some species can become invasive and out-compete native plants.
Over 500 non-native species are naturalized in Ohio (Cooperrider et al., 2001), of these about 100 invade natural areas. The degree to which invasive plant species affect Ohio natural areas varies, but some of these plants pose serious threats to native species and the ecological integrity of Ohio’s native biological diversity.
This report contains Ohio county maps showing the current documented distribution of 65 invasive plant species.
