MAISRC focuses its research efforts on species that have been prioritized based on their proximity to Minnesota, pathway of spread, and impact. This list of high risk/high priority species is updated annually with the help of a 9-member inter-organizational Technical Committee (MTC) and with input from the Center’s Advisory Board and the Center’s faculty members.

Active research is underway at MAISRC on many of these species. We will expand our research to additional priority species as funding and partnership opportunities become available.

Species currently being researched at MAISRC:

Eurasian & hybrid watermilfoil

Eurasian watermilfoil (Myriophyllum spicatum L.) is an invasive exotic aquatic plant that was introduced to North America in the early 1940s. It grows rapidly and tends to form a dense canopy on the water surface, which often interferes with recreation, inhibits water flow, and impedes navigation. Learn more.

Curly-leaf pondweed

Curly-leaf pondweed (Potamogeton crispus) inhibits the growth of native species and interferes with recreational activities. It disrupts valuable services including stabilizing sediment, improving water quality, and providing support for fish and other animals. Learn more.

Starry stonewort

Starry stonewort is an invasive green alga that can grow tall and dense, forming mats on the surface that interfere with recreation and potentially displacing native plant species. Learn more.


Invasive Phragmites is a tall, densely growing grass that can take over large areas, push out native vegetation, and reduce habitat quality for wildlife. Learn more.
