2023 Garlic Mustard Pull-A-Thon

Raise funds for your local group by pulling invasive plants

It’s time to get outside to pull together and raise funds during our annual Garlic Mustard Pull-A-Thon. Now in its eleventh 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!

This is a terrific 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 to your favorite team. Our 2023 goal is to reach a multi-year milestone of 100 TONS pulled! We are only 14,347 pounds short of that achievement. Our teams have fun 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 rises to the top by June 30, 2023 will earn bragging rights and take home the legendary traveling trophy. 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.

Invasive Plant Management Workshops

Workshop Spring 2022 1

nrf Logojohnsons nursery logo 300

Many people in southeastern Wisconsin work to control exotic invasive plants in our natural areas. During 2023, SEWISC will team with Johnson’s Nursery, Inc.TM and Natural Resources Foundation of Wisconsin to offer our Invasive Plant Management Workshops. 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.

This is a hands-on, bring-your-own lunch class, limited to 20 students to provide excellent instruction. After an introduction to the general ecology of the five functional groups of invasive plants (shrubs, perennial forbs, clonal perennials, grasses, and annuals/biennials), we discuss, demonstrate, and practice all applicable control methods (chemical and non-chemical) for these five plant types.

Workshop topics include:

  • Identification of our common and relatively new invaders
  • Planning and strategy for an effective control program
  • Use of hand tools and herbicide application methods
  • Herbicide concentrations, mixing, and safety
  • Restoration strategies for badly infested sites
  • Native planting suggestions for continued restoration
  • Record keeping

Even modest efforts can make a substantial difference toward reducing the impact of invasive species. Urban landowners as well as those who own and manage larger acreages can now encourage good stewardship and backyard conservation practices by posting these signs. Whether you have rural acreage, a suburban yard, or a city lot, you can help protect the environment by controlling invasive species and promoting that stewardship practice to others.

The high-quality 9x12 inch aluminum signs are available for only $20.00 each, or two for $35.00 (price includes shipping and handling).

SEWISC Board of Directors

2023 brought the sad departure of valued Director, Julia Robson, who served on the Board for a total of 9 years. First elected as a Student Board Member in 2012, Julia’s professional expertise and leadership quickly placed her on the Board Executive Committee. After a brief sabbatical from 2016-2017, Julia was recruited and re-elected in 2018, resuming her Board leadership role along with her commitment and passion for the SEWISC mission. Julia continues acting as our social media volunteer and we are grateful for her service!

Join us in welcoming our newest Director, Danielle Bell, who joined our Board in January and will serve an initial three-year term. Danielle’s passion for the outdoors started as a small child exploring the natural world with her parents. This love and excitement grew with her through college where she received a BS in Conservation and Environmental Sciences and a BS in Architectural Design.

Danielle has worked in the green industry for 10 years with multiple landscape companies to manage properties composed of a variety of native habitats. Watching the delicate and unique interactions between native flora and fauna strengthened her passion for the natural world and led her to start her company with the focus of reintroducing native plants into the landscape fabric of our cities and suburbs. Danielle enjoys spending time outdoors with her husband and daughter hiking and camping throughout our beautiful state.
