2019 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 seventh 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!

2018 Pull 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 donate. Our 2019 goal is to collectively pull 20,000 lbs. (10 TONS!) 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, 2019 will earn bragging rights and our legendary traveling trophy. Our natural areas will only avoid damage from invasives with long-term sustained commitment to control of invasives. 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 SEWISC Board of Directors

In January we expressed tremendous gratitude to newly retired Board Member Dan Carter for his commitment to our mission. Dan served on the SEWISC Board for 3 years, sharing his enthusiasm and expertise as an excellent botanist and ecologist. We are fortunate that Dan will continue reaching out to and educating our residents through his position with the Southeastern Wisconsin Regional Planning commission. Three new Directors will try to collectively fill Dan’s shoes. Join us in welcoming:
