2020 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 eighth 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!

trophy day support1This 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 2020 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 rises to the top by June 30, 2020 will earn bragging rights and take home the 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.

Here are our Annual Pull-A-Thon objectives (yea, let’s DO THIS!):

  • 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 educational funds for SEWISC and our partner organizations.

Even modest efforts can make a big 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).

To order just download, complete, and send a SEWISC Sign Order Form with your payment.

Funds to Control Invasive Plants Along our Roadways

JKWSEWISC continues to assist and support southeastern Wisconsin roadway maintenance crews in their efforts to control invasive plant populations which were mapped through the efforts of more than 150 resident volunteers.  Wild parsnip, common and cut-leaved teasel, Japanese knotweed and common reed grass populations are the target of these citizen science inventory efforts. 

SEWISC held meetings with key representatives in more than 100 cities, towns and villages in our region.  The invasive species inventory data was shared with the local officials and roadway managers during those meetings along with methods to control those populations. Roadway managers expressed a need for additional funding to control the populations, so we set our sights on securing those funds.

Nearly $551,000 in Great Lakes Restoration Initiative funding through the Environmental Protection Agency was awarded to SEWISC for the control of 2,174 populations of our target inventory species along the roadways in Sheboygan, Ozaukee, Milwaukee, Racine and Kenosha Counties. Roadway crews in those counties must use this funding for control efforts by September 30, 2020. Visit our Roadside Inventory and Management web page for more information and to view the map for your area. Local governments must contact us soon for your sub-awards details.

SEWISC Board of Directors

Our thanks to past and our welcome to new members

2020 brought the departure of three treasured Board Members.
