The following list has been developed using criteria created for this purpose. Species on the list are either potentially invasive or invasive.
Invasive species are either widespread or have a restricted range in Connecticut.
These two terms are geographic descriptors and do not imply degree of invasiveness. The list is intended to be an educational tool. This list is not static and will be reevaluated in December 2000. A species as listed here includes all subspecies, varieties, forms and cultivars. Life forms and broad habitat descriptors for habitats that are primarily threatened are noted.
