2018 Garlic Mustard Pull-A-Thon

Raise Funds for Your Local Group by Pulling Invasive Plants

It’s time to pull together and raise funds during our annual Garlic Mustard Pull-A-Thon. Now in its sixth year, the event encourages folks across southeastern Wisconsin to protect their local woodlands by pulling this invasive plant. More people are participating each year, so spread the word and join us to help stop the spread of garlic mustard!

2017 pull a thon champsThis is a great opportunity to raise funds for your own organization as well as our regional efforts to fight invasive species. You can form a team, join a team and/or donate. Our 2018 goal is to collectively pull 10,000 lbs. of garlic mustard and have a great time together while protecting natural areas from invasive plant damage. Securing pledges is easy – sponsors can donate directly through our website. Pullers are encouraged to ask friends, family and others to support their efforts in caring for the land.

The pull-a-thon is also a competition, so the team that collects the most pledges and pulls the most garlic mustard by June 30, 2018 will earn bragging rights and our legendary traveling trophy. Our natural areas will only avoid damage from invasives with long-term sustained commitment to invasives control. Half of all proceeds go to participating organizations that raise funds, and half go to SEWISC. All funds will be used for invasive species education, prevention and control in southeastern Wisconsin. Contributions are tax-deductible.

Pull-A-Thon Objectives:

  • Promote repeated control and proper disposal of garlic mustard and dame’s rocket in our parks and natural areas.
  • Promote public awareness of invasive species issues.
  • Share control methods and best management practices with landowners and managers and strengthen local volunteer efforts.
  • Raise operational funds for SEWISC and our partner organizations.

New additions in 2018 include two Directors who will each serve initial three-year terms. Join us in welcoming:

New Zealand Mudsnails Invading Southern Wisconsin


New Zealand MudsnailThe New Zealand mudsnail (Potamopyrgus antipodarum) is a listed NR40 prohibited invasive species. The small snail can establish large populations that can out-compete native stream insects that serve as food for fish. The mudsnail populations can change the nutrient flows in streams. All of the locations where New Zealand mudsnails have been found in the state are popular for fishing and may also be used by paddlers, trappers and hikers. The spread of New Zealand mudsnails and other invasive species can be stopped by INSPECTING and REMOVING all plants, animals, mud and debris from your equipment, and DRAINING all water from equipment and drying as much as possible.
