2022 Education Symposium & Sweat Equity Awardee

Our Educational Symposium was informative and fun!  Award-winning Landscape Architect and owner of Landserve, LLC, John Mariani,discussed Native Plant Replacements for Exotic Invasives.  We learned about using indigenous plants in an aesthetically-pleasing yet functional design and how to highlight plants that are the best substitutes for non-natives. Learn more about John's ideas at Landscapes for Life!

Symposium attendees celebrated this year’s Sweat Equity Award Winner, Jean Weedmana remarkable leader, inspirer and native plant enthusiast who has devoted more than a decade to promoting stewardship of our natural resources in southeastern Wisconsin.  Everyone enjoyed local food refreshments and 5 lucky raffle winners returned home with nearly $600 in fantastic donated prizes! 

Mark your calendars for our next Educational Symposium: November 7, 2023.

2022 Garlic Mustard Pull-A-Thon

Congratulations to the 2022 Champion Pull-A-Thon Team!

2018 Pull Champs 2 1024x828Our Garlic Mustard Pull-A-Thon is an annual fundraiser event, where we encourage folks throughout southeastern Wisconsin to protect the woodlands of their neighborhoods by pulling this invasive plant. This season, 327 dedicated residents formed 10 volunteer teams which helped to raise funds and awareness while controlling 12,069 pounds (over 6 tons) of garlic mustard and dame's rocket in our natural areas. Volunteers recruited friends, family and colleagues to sponsor their pulling efforts. $1,475 in pledged contributions was also collectively raised by team members and shared between SEWISC and the event partners. These funds will be used for adult and youth invasive species education, prevention and control in southeastern Wisconsin. 

This year, The Cedar Lakes Conservation Foundation Team pulled themselves to the top of the 2022 Garlic Mustard Pull-A-Thon competition. Led by Abby Brostrom, the team enlisted 45 volunteers and recruited $475 in donations while pulling 2,535 pounds of our target plants throughout a 30-acre management area.

Jean Weedman, Team Leader of our 2021 Champion Eagle Nature Trail Team, graciously passed the traveling Garlic Mustard Pull-A-Thon trophy to Cedar Lakes Conservation Foundation Team Leader, Abby Brostrom, during a ceremony officiated by SEWISC Board President, John Lunz in early August. The trophy will be proudly displayed by Cedar Lakes Conservation Foundation throughout the year.

Many thanks to all of you who got outdoors, pulled garlic mustard and dame’s rocket, told your neighbors about these invasive plants, and reported your progress as part of the 2022 event. And thank you to all who donated to your favorite 2022 Team! Remember, it's never to early to start planning for next year's Pull-A-Thon competition - JOIN US
