Not from around here?

Invasive or non-native species travel well. They can come from distant countries or neighboring states. 

Baby BOOM!

Whether hundreds of seeds or millions of eggs, invasives have a reproductive advantage that allows more offspring to survive and continue the cycle.

Invasive species are generalists. They can eat a wide range of foods and survive in many conditions.
