U.S. federal noxious weed list

U.S. state lists of noxious weeds

For now, these links will go straight to the (official, if known/possible) noxious weed list for the listed state. Eventually, it is planned to have a page for each state with additional links (e.g. including text of the state laws, etc. if available).

There is also a more comprehensive listing of this type of info available on the USDA/ARS/GRIN website. Additionally, the USDA list of noxious weeds is searchable by state/etc. online. (The webmaster is currently trying to figure out the relationship, if any, between these two sites. Please contact the webmaster [webmaster@hear.org] if you can shed light on this issue.)

Also, there is a publication entitled Halting the Invasion: State Tools for Invasive Species Management (produced by the Environmental Law Institute [ELI])) detailing (with analyses) state-by-state invasive species laws. Further information about this document is available online.
