Noxious Weeds in the U.S. and Canada

This web site provides a searchable database of the noxious weed lists for all U.S. states and six southern provinces of Canada. The database can be searched by plant name, state name, or by clicking on a map. The search can be narrowed down to search for native, exotic, or all species of plants for a particular county. Furthermore, the search can be conducted for the time period that the user chooses. A summary of this database provides a list of all noxious weeds, which can be customized to display in alphabetical order (on scientific name) or by the number of appearances on weed lists.
