Many invasive species that currently threaten regional forests may benefit directly from projected climate change or benefit from the relatively slower adaptation response of native species. Increases in carbon dioxide increase growth for many plant species, andcChanges in climate may have allowed some invasive plant species to expand their ranges northward, including bush honeysuckle, privet, and kudzu. Some invasive species are tolerant of drought, fire, flooding, and other disturbances and may be at an even greater advantage under future climate conditions. A lack of information regarding the climatic thresholds for many invasive plants limits the ability to predict future spread. Additionally, it is not possible to predict all future nonnative plant species that may enter the assessment area during the 21st century.
