Why are invasive species such a problem?

• Invasive species do not have other animals that eat them in the new area where they live, so nothing stops them from reproducing out of control.

• Invasive species do not encounter diseases that they could die from, so nothing stops them from reproducing out of control.

• Invasive species use up resources like food and shelter that prevent other animals from carrying on with their normal lives.

How does an invasive species "take over?"

• They are meaner and hunt better so all of the other animals in the area run away.

• They make other animals in the area give them their lunch money because "they control these streets!"

After many years of owning a few pet goldfish, you decide to set them free in a nearby pond. The following year, you glance into the pond and realize that your goldfish was invasive to the pond. How do you know?

• The goldfish had no natural predators so it reproduced uncontrollably.

• The other fish couldn't reproduce as fast as the goldfish because there was not enough food or shelter for them.

• You did a good thing by releasing your goldfish because now it is part of a goldfish population, and is no longer lonely.
