In an online article published In Interventional Science and Plant ManagementJustin D. Salva and Bethany A. Bradley conducted and reported impact assessments on 104 plants most likely to expand with climate change in one or more of the eastern US (Delaware, Kentucky, Maryland, New Jersey, Ohio, Pennsylvania, Virginia and/or West Virginia) by 2050.
Among these plants, 32 are high impact species associated with negative impacts on ecological communities or many native species, and many are also associated with socioeconomic impacts.
“The new research helps prioritize which invasive species to target in the area for proactive prevention and management,” says Bethany Bradley, Ph.D., Professor of Biogeography and Spatial Ecology in the Department of Environmental Conservation at the University of Massachusetts-Amherst.
“The impact assessment generated in this study and related companion documents in New York and New England states can inform state weed risk assessments by identifying emerging invasive species that are most likely to cause negative impacts, including many associated with the trade of ornamental plants. “
