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 these guidelines to reviewers, along with a detailed spreadsheet to complete with their observations.

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?

Note: Some species display blank maps because of insufficient review data to populate the map. The ‘insufficient data’ tag in the maps means that there were fewer than 3 reviews for that species/region. There is also a ‘no data’ tag for those without any reviews. These plants are included in the assessment list because they are known as invasive and/or are regulated in neighboring states.

What’s Next

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