What makes a species "invasive"?

"Invasive" species come from other watersheds, other regions or other continents. In a new landscape, they may have no natural controls, such as predators. As a result, non-native animals, such as feral hogs, often eat local wildlife or their foods and consume or destroy their habitat. Invasive plants, such as spotted knapweed, can also outcompete crops and livestock forage, reducing economic productivity.

What's the difference between "invasive" and "nuisance"?

"Nuisance" animals are native to the local landscape but can cause problems. Canada geese, for example, have historically used Missouri for summer breeding grounds, but they have become nuisances where they have year-round access to short, palatable grass and open water.

What can I do about invasive species?

If you care about crops and native wildlife, please do what you can to control invasive species when you landscape, farm, hunt, fish, camp, or explore nature. Invasive species and their seeds can travel on tires, clothes, in bait buckets and firewood.
