Invasive Species: Plants

Below is a species list for plants in Wisconsin which are known to be invasive in Wisconsin or may be potentially invasive. The species with literature reviews, identified as "Prohibited" or Restricted", have gone through a scientific review and assessment process and are part of the invasive species classification system in the proposed NR 40 (DNR Invasive species identification, classification and control rule). For more information on these rules click here.

The plants marked with an asterik (*) were assessed for the proposed NR40 rule. All other species have not yet been assessed through the rule process. Most will likely be considered for evaluation and assessment in a future rule revision.

You may view the available factsheets, literature reviews, and photo galleries by clicking the corresponding icon.
