Family Activity: Invasive Species

Invasive Species KudzuMoving plant and animal species to new environments can be beneficial, but can often cause environmental and economic harm.

Doing the Activity

The next time you are in the forest or other outdoor space, introduce the term “invasive species” to children and discuss its meaning by asking:

  • How would this area look different if a family of elephants lived here?
  • What impact would the elephants have on the plants and animals nearby?
  • Where do elephants live in the wild?
  • Why don’t elephants live here?

Of course, elephants have not invaded woodlands of the United States, but invasive species are impacting local forest ecosystems.

For example, Tree of Heaven (or Ailanthus) is an invasive plant originally from central China, now found in 30 U.S. states. It is often mistaken for the native Black Walnut and left to grow and reproduce.

Tree of Heaven grows rapidly, is difficult to remove, and displaces native plants.
