Got garlic mustard? Join the competition!

spring news1Our Garlic Mustard Pull-A-Thon is an annual fundraiser. Young people and adults throughout Southeastern Wisconsin work to protect the woodlands of their neighborhoods by forming teams to pull this invasive plant.

Since the Pull-A-Thon began 10 years ago, teams have collectively pulled more than 87 tons of garlic mustard and dame’s rocket! Each year, our goal is to collectively pull 20,000 pounds and raise funds to fight invasive species.

The pull-a-thon is a competition, a fundraiser, and a way for people to join together to have a positive impact on their environment. Our natural areas need your help to avoid the damage that invasives cause!

Each spring Pull-A-Thon Teams are forming throughout Southeastern Wisconsin. A trophy and bragging rights will be awarded to the team that pulls the most garlic mustard/dame’s rocket and pulls in the most donations by June 30.

Why Are We Pulling?

Garlic Mustard (Alliaria petiolata) is an invasive plant that’s taking over our woodlands. It crowds out our native wildflowers and endangers forests by preventing tree seedlings from growing. To make matters worse, none of our native insects or wildlife eat it!

Dame’s Rocket (Hesperis matronalis), another invasive member of the mustard family, can be pulled and bagged along with garlic mustard during the competition, giving each team extra pounds we call a Rocket Boost!

Invasive Plant Management Workshop

Many people in southeastern Wisconsin work to control exotic invasive plants in our natural areas. SEWISC is teaming with Johnson’s Nursery, Inc.TM to offer our Invasive Plant Management Workshops twice annually. Take this class to ensure that you are using the most appropriate, efficient, up-to-date, and least environmentally damaging methods in your control efforts.
