OkIPC Watch List Statement of Purpose 

 

In addition to the Dirty Dozen List of Unwanted Invasive Species, the Oklahoma Invasive Plant Council has created a Watch List of invasive plant species known to be one or more of the following:   

 

  1. present in Oklahoma and/or a bordering state  

  2. negatively affecting the economy, environment, or human health in Oklahoma and/or a bordering state    

  3. listed as a noxious weed or an aquatic nuisance plant species in Oklahoma and/or a bordering state 

 

This list is to be used to facilitate education and management of invasive plant species in Oklahoma. The Watch List is not a static document and is subject to change as new data become available.
