Backyard Invasives

They may look innocent in your backyard, but invasives can pose a serious environmental threat.

Do You Have an Invasive Species in Your Backyard?

Once used widely in gardening, landscaping and erosion control, non-native plants like those pictured here can be found in yards, along roadsides and in business lots across the country. Free from natural restraints, alien plants, pests and diseases can establish themselves in new areas and eventually supplant native species.

You can help! Click on each of the pictures to learn what you can do to fight invasives and preserve the species native to your region.
