Missouri Invasive Plant Task Force (MoIP) - to identify and control the invasive plant species that severely impact native biodiversity

Missouri Invasive Plant Task Force (MoIP) Invasive Plant Assessment

The Missouri Invasive Plant Assessment is a comprehensive statewide assessment of known and potentially invasive plants. The completion of this assessment meets one of MoIP’s critically important priority goals.

Our Approach

Starting with our network of local, state and federal agencies and private industries, MoIP sought input from experienced field biologists in Missouri. 

MoIP sent the following guidelines to reviewers, along with a detailed spreadsheet to complete with their observations.

Download the original guidelines (PDF).

MoIP received 26 completed reviews.

Categories of Assessment

MoIP invited reviewers to assign independent ranks for the following three categories:

1). Impact: 
How severe is the current impact of the species on natural communities in each of Missouri’s primary ecological regions?

2). Current Abundance: 
Estimate the species current abundance in each of Missouri’s primary ecological regions.

3). Trend in Distribution and Abundance: 
Based on observations and regional trends over the past 10-20 years, estimate how rapidly the species range will expand to form new occurrences throughout each of Missouri’s primary ecological regions over the next 10 years?

  • MoIP will consult with attendees of the 2019 Missouri Natural Resources Conference regarding what kind of lists, if any, would be useful to them in their professional fields.

What’s Next

Nothing in nature is static.

This assessment will be updated every several years based on additional and on-going in-the-field observations and reviews.

Would you like to be informed of our next assessment season? Please enter your information below, and we will contact you before our next assessment period.

Do you have an observation to share?

You may report observations of invasive plants in your area any time using the Mapping MO Invasives app or EDDMapS Midwest. These real-time mapping systems for documenting invasive species distribution are fast, easy to use and important for early detection and rapid response to invasive species before they become unmanageable problems.

State verifiers review all data to ensure accuracy. The data are made freely available to scientists, researchers, land managers, land owners, educators, conservationists, ecologists, farmers, foresters, state and national parks.
