About This Quiz
Sometimes it starts with good intentions, like trying to rid a sugar cane plantation of rats, and ends with mongooses eating everything else on the island -- except rats. Most times, it's due to our shrinking world with insects, plants and microscopic organisms hitching rides on freighters, supplies, and introduced in the ballast water of ships. If you're into ecosystems, or just keep up with the news, you'll know many of these invasive species. But can you name them all? Try your best and see if you can match the invasive species to the clues given. Don't wait, start the quiz now.
Broadly speaking, an invasive species is non-native and whose introduction causes environmental harm, pushing out the native species. Have you heard of Red Fire Ants? How about the Sea Lamprey? Then there's the Asian Citrus Psyllid that does damage to the trees that produce your favorite breakfast juice. In most cases, these invasive species have common features: high rates of reproduction, no known predators, and easy prey. Has your mind been invaded with the correct answers? Then it's time to take this quiz and see how much you really know about the world around you. Start now by clicking the button below.

What is native to Asia and Australia and is now shading out vegetation in Florida?
Old World climbing ferns sprout on trees and don't allow native vegetation to bask in the sun all over east-central Florida.

What is the name of the invasive species known as the "vine that ate the south"?
Although the Kudzu was introduced at the Japanese pavilion in the 1876 Centennial Exposition in Philadelphia, the vine didn't take hold here until nearly 55 years later when it was reintroduced as a way to stop soil erosion on farms.

A pine tree's natural defenses don't work with which one of these invasive species?
When insects bore into pine trees, the trees fight back by increasing their flow of sap, a defense that forces the invaders out of the holes in the bark. Unfortunately, pine beetles produce a fungus that disables this defense. Eventually, unable to absorb water, the pine tree withers and dies.
