Groundswell Conservancy
Our mission is to protect special places, forever. Our Mission: Protect special places, forever. We are a Wisconsin nonprofit and community-based organization.
We believe everyone should live in a world filled with green places where communities thrive. Land is essential for people’s physical, emotional, and spiritual wellness. All should enjoy equitable access to the benefits of land and nature. If we don’t protect undeveloped land now, it may be lost forever. The environmental issues facing our world have never been greater – our climate is changing, farmland is disappearing, not everyone has good access to land, wildlife habitat is vanishing, and people are losing their connections with the outdoors. Groundswell is pushing back. With the help of our supporters, landowners, partners and volunteers, we are taking on big issues with focus and resolve. Acre by acre we are getting results. How We Work:
-Act on Climate Crisis
-Connect People with Nature
-Conserve Wildlife Habitat
-Provide Equitable Access to Land
-Keep Farmland, Farmland
-Create Green Schoolyards

"If you’ve wandered aimlessly, or even purposefully, through a prairie this month, you may have noticed quite a few banded garden spiders out and about. Their webs are incredibly strong, and I often find surprisingly large grasshoppers tangled up in them. The evening I found this particular spider, the sunlight was hitting its web just right, creating such a striking scene that I had to stop and take a photo.
I did a little research on banded garden spiders and discovered that they often orient their webs from east to west. They also tend to hang head-down with the dark underside of their abdomen facing the sun, allowing them to absorb as much solar heat as possible late in the year. In other words, this spider's positioning wasn't random at all!"
From sunbathing banded garden spiders to the adventures of fungi fanatics, there's a lot happening outdoors!

Celebrate the grand opening of the Marsh Lake Public Access Project with us! 🚣
When: Thursday, October 1, 4 p.m.
Where: Marsh Lake Public Access Area
Join us as Jefferson County WI Parks officially opens the new accessible canoe and kayak launch, and parking area at Marsh Lake. These improvements create a welcoming access point for paddling, wildlife viewing, and exploring this special landscape. You’re encouraged to bring your canoe or kayak and give the new launch a try following the ribbon cutting!
This event also celebrates the many people and partners who made this project possible. Originally owned by the Trieloff family and protected by Groundswell, the property will be managed by the Wisconsin Department of Natural Resources as part of the Lake Mills Wildlife Area.

🔊 VOLUME UP 🔊 Do you hear that noise? It sounds like seed collectin' time!
Our Land Management Director, BJ Byers, captured this video of flowering spurge (Euphorbia corollata) pods *crackling*. Once collected and dried, the seed capsule of this pollinator plant ruptures, creating a crackle/pop noise, and ejects the seeds out of their pods a short distance. And no, this doesn't just happen in kitty pools–that's just our process for drying out the seeds we collect from our preserves to help us prep for dispersal. 🍂
Want to learn more about these fascinating parts of nature and get involved in the fun? Join us for seed collecting at Westport Prairie this fall:
TOMORROW–Wednesday, Sept 30, 9–11 a.m.
Wednesday, Oct 14, 9–11 a.m.
Thursday, Oct 15, 4–6 p.m.
Thursday, Oct 29, 4–6 p.m.

Land Trust Alliance Rally may be over, but we're still smiling! 💚
Four of us traveled to Denver, CO for Land Trust Alliance's Rally 2026 Conference. Our staff attended learning sessions on land conservation and farming, fundraising, stewardship, and more. We connected with dozens of land trusts from across the nation to collaborate on our conservation efforts, build lasting partnerships, and bring back fun and inspiring stories!
Thanks to LTA for creating a space where our community of land trusts can continue to grow and strengthen. A special thank you goes to the Oberweiler Foundation for making opportunities like this possible for our staff.

"If you’ve walked the drumlin at Westport Prairie this summer, you may have noticed flags and cages scattered across the hillside. These mark Jillian Neece’s graduate research at UW-Madison where she’s studying milkweed pollination.
She’s excluded certain pollinators from milkweed flowers with mesh of varying sizes, and is now testing the seeds for successful pollination as they mature. In essence, Jillian is working to understand which insects actually pollinate milkweeds and whether milkweeds depend exclusively on larger insects to set seed."
It's migration season for monarchs butterflies at Westport Prairie, and there's a lot happening in the field for these pollinators. Check out this month's Field Notes from Groundswell's Farm & Land Manager Sam Douglass to learn about our work with monarchs and milkweed, from seed production research to butterfly tagging 🦋

Thank you to the City of Sun Prairie, Wisconsin, USA for honoring Groundswell Conservancy with a 2026 Charles D. Ashley award! This annual award is presented to Sun Prairie citizens who have done the most good for their community this year.
Members of our Groundswell staff, supporters, board, and volunteers accepted the award at the City Council Meeting this past Tuesday.
Last year, Groundswell worked with the City of Sun Prairie and the Wisconsin Department of Natural Resources to create more opportunities for people to enjoy nature at Patrick Marsh. After protecting this wetland gem with a conservation easement, Groundswell gave Patrick Marsh to City of Sun Prairie to create their first conservation park! The preserve will continue to be managed by Groundswell and remain a beautiful place that connects people to nature. 🛶

A lot is happening at the Groundswell office, and we're making time to celebrate the work we do for our special places, together 🌱
Recently, Groundswell hosted staff and board outings in the Town of Westport. Our staff ventured out to Westport Prairie to collect seed for this winter's 18-acre prairie planting! It's a ripe time of year on the drumlin, and we had a lot to collect: flowering spurge, sideoats grama, lead plant, purple prairie clover, and cylindrical blazing star. 🪻
Then, we gathered at Westport Town Hall for our Board of Directors meeting before heading out to Westport Farms for an evening of good food and conversations about our equitable farmland access work. Thank you to the Town of Westport for hosting our board meeting and to everyone on our team who made these events possible!
