Fifteen woody species with potential for invasiveness in New England.

In a recent paper (Herron et al. 2007), we published a statistical model for predicting invasiveness of exotic woody plant species in New England. A dataset was compiled of 28 biological/ecological characters for each of 248 exotic trees, shrubs, and lianas currently available in the nursery trade in northeastern North America. Using a Bayesian hierarchical analysis, we were able to compare non-native species that are known invaders to non-native species that are not currently considered invasive in New England. The model identified a suite of biological/ecological traits that may be useful in predicting invasiveness, and also identified a set of 15 species as potential new invaders in New England. Our conclusion was that these species warrant further study and ought to be monitored in the field, and here we present a more detailed discussion of species-level results and their implications. Model results were synthesized with additional botanical and field information for these species, and their current status (based on records held at regional herbaria) and potential for spread are discussed. Our intention is to vet this list of potential invaders to the botanical community, and to stimulate further study and observation before they become widespread. While some of the predicted invaders are well-known as naturalized species and are being monitored, others are currently not appreciated as potential invaders, or even widely known at all. The following species were predicted by our model as future exotic invaders in New England: Albizia julibrissin, Ampelopsis aconitifolia, Caragana arborescens, Colutea arborescens, Euonymus europaeus, Halimodendron halodendron, Ligustrum amurense, Polygonum baldschuanicum, Robinia hispida, Rubus armeniacus, Spiraea japonica, Tamarix ramosissima, Viburnum lantana, Viburnum opulus var. opulus, Wisteria sinensis.
