Early detection of aquatic invasive plants

Close-up of brittle naiad

When new invasive species reach an area, we can minimize their impact through early detection and rapid response. There are invasive species that are known to cause large impacts elsewhere in the Midwest but are not widely distributed or present in Minnesota. By finding and treating invasive plant populations while they are small, we have a better chance of controlling the population and preventing the species from spreading to new waterbodies.

Criteria for early detection target species are non-native, invasive plants with limited distribution in Minnesota that are assessed as high risk. Please report the location of an invasive aquatic plant.
