The Invasive Plant Advisory Committee (IPAC) was created in August 2010 with Ellen Jacquart as chair, to work on invasive plant projects that support the mission of the IISC. Since inception, the IPAC has: 

  • Created an invasive plant list for Indiana that the IISC adopted as an Official Invasive Plant List for the state of Indiana.
  • Developed Best Management Practices to reduce the movement of invasive species.
  • Completed a new invasive plant brochure, "Pretty Awful."
  • Created an invasive species database through the Early Detection Distribution and Mapping System (EDDMapS) identified as EDDMapS Report IN.

Dawn Slack is the current chair for IPAC.  She and the IPAC team are working on the following:

  • Evaluating the IISC 3rd biennial conference that was held February 15, 2018. Survey results indicate needs for additional networking and training meetings. IPAC is working with IISC and Purdue to host follow-up meetings. 
  • Beginning the process of updating the Invasive Plant List
    • Reassessing plants on the invasive plant list ranked low or lacking information
    • Assessing new nonnative plants for invasiveness
  • Garnering support for the proposed Terrestrial Plant Rule
  • Working with Purdue to update the IISC website
  • Providing the IISC with current and emerging invasive plant issues
  • Providing updates on EDDmapS invasive plant reports
  • Keeping current on invasive plant issues through existing networks and new networks
