Combatting Invasive Species

Invasive species—non-native plants and animals from other parts of the world that cause ecological harm—are one of the biggest threats to wildlife and their habitats in the United States.

Non-native invaders affect people’s quality of life and harm our pocketbooks by clogging drinking water pipes, killing trees and spreading diseases.
