Six Easy Ways to Fight Invasive Species

6 Easy Ways to Fight Invasives

While working as a naturalist a few years ago, I’d take kids on long hikes in central Ohio and point out the “tree of heaven.” We’d admire its beautiful red blooms amongst its fern-like leaves and then proceed to hack and whack at the trunks, pulling as many saplings out of the ground as we could. Appealing to the eye, yes, but like all invasive species, Ailanthus poses a real environmental threat to native species.

Once used widely in gardening, landscaping and erosion control, we very naively imported many non-native plants like kudzu, thinking they’d get along great with the natives and improve nature in general. Now we know better, but invasive species are still making their wily way into native territory and causing an ecological ruckus. (See brown tree snake or autumn olive.)

So what’s the best way to fight non-native plants and animals? The #1 way to fight invasives is to prevent them from occurring in the first place. How can you help do this? We’ve got six easy ways to combat and prevent invasive species:

  1. Make sure the plants you buy from local nurseries are native to your area. Surprisingly, some nurseries still sell varieties of invasive species.
  2. Don’t release aquarium fish and plants, live bait or other exotic animals into the wild. Florida’s burmese python invasion is believed to have been caused by people releasing their non-native pets into the wild.
  3. When boating, clean your boat thoroughly before transporting it to a different body of water.
  4. Clean your boots and clothing before and after you hike in a new area to get rid of hitchhiking weed seeds and pathogens.
  5. Don’t “pack a pest” when traveling. Fruits and vegetables, plants, insects and animals can carry pests or become invasive themselves.
  6. Volunteer at your local park, refuge or other wildlife area to help remove invasive species. Help educate others about the threat.

  1. The EAB has been located 45 miles north of here. I wanted to treat my trees but I think it is too late for this year. Will I risk my trees by waiting until spring 2014?

    1. Hi Meg,

      I am not sure where you are located, but I myself live in Iowa and the EAB was just found in our state for the 2nd time. A very disappointing find. I am not an invasives expert, so I can’t advise you on how to treat your trees. I would suggest contacting the local Parks or Forestry service in your area and start there. Thanks so much for your comment, and for being aware of invasive species!

  2. These are good…but I would change point four to read:

    Clean your boots – and clothing – before and after – each hike to get rid of hitchhiking weed seeds and pathogens.

    If you are primarily checking before, then anything you picked up on the last hike you have been transporting and possibly shedding.

    1. Thanks so much for that comment, Sandy. A great point indeed. I will update that tip to reflect your suggestion. Thanks again!
