Identify and remove invasive plants.

Visitors from other countries are great, but when they come in the form of plants, they can be devastating. These "invasive plants," usually snuck into the country by people, can destroy native vegetation. So learn to identify these "invaders"—and how to get rid of them.

Kids Take Action!: If you have chosen this activity, tell us about it, and get an official National Geographic Be a Habitat Hero certificate!
