Come clean and leave clean to stop spread of invasive plants

Don’t transport unwanted visitors as you’re enjoying the back country

Warmer weather has returned, and as summer starts to wind down you might be heading outdoors to hike, bike, fish, and explore the back country.

Did you know recreational activities can be inadvertent vectors of invasive plant spread? If you are planning on hopping in your boat, on your bike, horse, or motorized vehicle, or are merely going for a hike, please follow these simple actions to prevent invasive plant spread in our beautiful outdoor areas:

COME CLEAN by removing plants and mud from your footwear, gear, and pets before exploring. It is important to prevent the spread of invasive species from your property to natural areas. This is particularly true if you have a garden at home or an invasive plant-infested pasture; seeds may be lodged in your boots or your pet’s fur. To remove plant burrs from pet fur, apply a little bit of coconut oil to the burr, pinch the burr until it breaks up, and then comb it out.

STAY on designated trails to reduce the chance of picking up seeds and mud that carry invasive plants. Staying on trails also helps keep our native plant communities and ecosystems healthy and strong, enabling them to resist invasive plants. When you go off trail, the resulting ground disturbance provides prime habitat for invasive plants, which are likely to establish themselves and out-compete our native plants.

DON’T PICK wildflowers. Picking wildflowers can result in two outcomes: the spread of invasive species and/or weakening native plant communities’ seed source. The best adventures are ones that leave only footprints. If you spot an eye-catching plant, take a photo.

BRING IN CLEAN RESOURCES such as weed-free hay for your horses and locally-sourced firewood for your camp. All firewood should be sourced from no further than 20km to prevent the spread of invasive insects, such as the emerald ash borer. This forest pest can naturally disperse about 10km per year, but with the help of humans it can travel 90km per hour!

LEAVE CLEAN by removing plant and muds from your footwear, gear, and pets after exploring. If you are on the water, practice Clean-Drain-Dry (https://stopaquatichitchhikers.org) to prevent the spread of aquatic invasive species. Be sure to dispose of unwanted bait in the garbage.
