Invasive Animals

Invasive wildlife species, like feral hogs and Asian carp, have made their way into Indiana habitats where they compete with valuable native species. Thanks to their ability to grow rapidly, reproduce quickly, and adapt easily to a variety of habitat conditions, these invaders are thriving. Typically, they will out compete our natives for resources and by doing so they decrease the populations of those species.

Invasive species are capable of dominating a landscape because their natural predators and control mechanisms are absent. Often, these species are not native to Indiana, but rather introduced from different countries and regions.

How can you identify a species as invasive and non-native?
Use the USDA National Invasive Species Information Center website as a starting point to read about specific threats to Indiana and access numerous informative links.

Also take a glance at Purdue's CAPS program where you can select your pest, habitat, or county to learn more about a pest species that could be problematic. Are any of your plants harmed by those on the "Most Unwanted" invasive plant pest species list?

DNR also lists invasive species that you may encounter in Indiana, with information on what to do if you think you spot an invasive plant or animal.

Invasive Animals to Watch For

A brief word about invasive animals
