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 US, but are not widely distributed or present in Minnesota.
By finding and treating invasive animal and insect populations while they are small, we have a better chance of controlling the population and preventing the species from spreading to new areas.
Criteria for early detection target species are non-native, invasive animals with limited distribution in Minnesota that are assessed as high risk.
