This table is to help trained IPANE Program volunteers submit records. This list has been generated from a variety of different sources including herbarium specimens, published lists, literature, and the observations of numerous botanists and naturalists. All taxa included here have preliminarily met criteria designed to evaluate those species that should be considered invasive or potentially invasive in minimally managed habitats in New England. These designation may not reflect official status in a state. Knowledge of current and historic distribution may be incomplete. The status of some taxa include here may change. Nomenclature is according to ITIS, the Integrated Taxonomic Information System (http://www.itis.usda.gov). For species marked with an asterisk (*), we are only interested in information about populations in minimally managed habitats
