Exotic invasive species are non-native plants, animals or microbes that spread aggressively, replacing native organisms and posing serious threats to human health and well-being, the environment, or our economy.


The Indiana Invasive Species Council (IISC) was established by the state legislature to enhance the ability of government agencies to detect, prevent, monitor, and manage new and long established invasions, as well as increase public awareness about invasive species.

Invasive Plant Advisory Committee

The Invasive Plant Advisory Committee (IPAC) was created in August 2010 to work on invasive plant projects that support the mission of the IISC.

If you have questions or comments about IPAC or invasive terrestrial plants please contact, Dawn Slack at dawn.slack@tnc.org

Invasive Plant Management Cost Hoosiers over $5 million in 2012
A recent survey conducted by the Invasive Plant Advisory Committee found that land owners and managers in Indiana spent $5.85 million in 2012 to manage invasive plants on their land.

Management Resources

Cooperative Invasive Species Management Areas (CISMAs) and Cooperative Weed Management Areas (CWMAs)

CISMAs / CWMAs are local organizations that bring together landowners and land managers, local, state and federal agencies, tribes, individuals and various interested groups to coordinate action and share expertise and resources to manage invasive species in a defined area. This collaborative effort at the local level enables CISMAs to pool resources and knowledge to address mutual invasive species issues.

  • Operate within a defined geographic area, distinguished by a common geography, invasive species problem, community, climate, political boundary, or land use;
  • Involve a broad cross-section of landowners and natural resource managers within its defined boundaries;
  • Are governed by a Steering Committee;
  • Make a long-term commitment to cooperation, usually through a formal agreement among partners;
  • Have a comprehensive plan that addresses the management or prevention of invasive species within its boundaries; and
  • Facilitate cooperation and coordination across jurisdictional boundaries.

CISMAs and CWMAs bring together local citizens, landowners, non-profit organizations, industry, and city, county, state, tribal, and federal representatives to work towards a common goal—effective control of invasive species.
