Invasive species expanding their ranges northward with climate warming will pose a major management challenge to the northeast. Working proactively to identify, monitor, and regulate these species will be most effective for minimizing future ecological and economic impacts. However, with hundreds of species to choose from, prioritization is needed. Coville et al. (2021) evaluated 87 species not currently present in northern New England (Vermont, New Hampshire, or Maine) but likely to expand there before mid-century. Using the Environmental Impact Classification of Alien Taxa (EICAT) assessment, they identified 24 species with reported impacts on ecological communities (e.g., causing a decline in the populations of multiple native species or in native diversity). Almost all (22) of these species are known to affect ecosystems found in the northeast.
