Other Resources

There are many resources you can link to help you determine whether your plant is considered invasive to your region. You might start with the USDA PLANTS database and NatureServe, then maybe a more regional source from the lists below. It is always a good idea to check more than one source. Once you have exhausted the lists below, you may also wish to explore our more general link-lists.

Weed Risk Assessments (NatureServe)
For use in assessing, categorizing, and listing non-native plants according to their impacts on native plants, animals, and natural communities and to make the process of assessing non-native species objective, transparent, and systematic. The protocol is intended to be applied to species as they occur over large areas, such as nations, ecoregions, provinces, or states. NatureServe has begun using the protocol in an effort to eventually assess the approximately 3,500 non-native vascular plants recorded as occurring outside of cultivation in the United States; by June 1, 2004 NatureServe had already completed 300 assessments. To look up a plant go to the NatureServe Explorer.
