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.

Report IN is a fast and easy way for you to report invasive species in Indiana. There are two ways to report – by computer and by smartphone. All reports will go to the appropriate organization for verification. To report by computer, go to www.EDDMapS.org/indiana and create a profile, then click Report Sightings and fill out the form.

To report by smartphone, download the Great Lakes Early Detection Network (GLEDN) app by CLICKING HERE. This app is created and maintained by EDDMapS.org and the same EDDMapS profile can be used for both computer and smartphone reports.

2020 Indiana CISMA Virtual Conference

Invasive Species and Watersheds

Now Virtual due to COVID-19

A Note From the Conference Organizers

Due to coronavirus (COVID 19) we are moving the 2020 Indiana CISMA Conference to a virtual meeting. In order to offer continuing education credits and keep the live virtual meeting of appropriate length for one sitting we will prerecord our five speakers presentations and make those available to conference registrants for 15 days beginning 01 August 2020. We will provide a link to registrants at the end of July to access all videos.

You will have 15 days to watch the five hours of recorded videos (approximately one hour for each speaker). Education credits through State Chemist (CCH) and the SAF will be available for those that watch the videos and answer questions associated with each video. We expect the ISA continuing education units to be available as well. We will send a link to the videos and include instructions on how to answer questions for those that want to obtain continuing education credits to registrants at the end of July.

On 20 August we will have a 2 hour live virtual meeting with all speakers present in a panel format. During the live virtual meeting, we will:

  • provide updates on the terrestrial plant rule and the new identification guide associated with the rule
  • provide an update on the state-wide Indiana Invasives Initiative project (project) and what our next steps are as we enter the next two years of the project
  • answer questions submitted by registrants
  • announce the 2020 Weed Wrangler awardees
  • announce the Weed Wrangle Indiana CISMA winner ($500 dollars prize to the winning CISMA)
  • conduct a networking session so you may spend time with others who are managing invasives and / or developing CISMAs, etc.

We will share a final agenda (see draft on last page), presenter biographies, and associated research on the impacts of invasive species soon.

We extend a thank you to all sponsors for sticking with us as we navigate the impacts of coronavirus - COVID 19. Approximately 300 people have registered (which is full capacity) so we recognize the need to hold this conference even if an in-person meeting is not possible, hence a virtual meeting.

We also want to thank each registrant. We hope that by offering prerecorded sessions and continuing education credits as well as a live session with project updates, 40 minutes of breakout networking sessions and more we meet your needs.

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@sicim.info

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.
