Glacial Prairies

Glacial Prairie Chapter is in the southeastern corner of Wisconsin, outside the Driftless Area. While our region lacks the hill prairies found in other chapters, we have some unique prairies associated with glacial till. Other prairies in the area include large sand prairies, some wet prairies, and the typical roadside and railroad prairies the escaped development. We work together in coops on lands of our members and partner with other organizations.  We also are active during the week with schools in the area, doing presentations and planting school prairies.

The Glacial Prairies Chapter covers Dodge, Jefferson, Kenosha, Milwaukee, Racine, Walworth, and Waukesha Counties in Wisconsin. We invite you to join us!

Tour Shining Oaks Preserve and have lunch with us! 

Saturday, May 18th - 10:00 am to 2:00 pm

Location: Jefferson County, WI, Summer Township (T5N, R13E), Section 6. The address of the property is: N2416 E. Rockdale Road, Cambridge, WI 53523


Shining Oaks contains remnants of a former savanna community in several areas. In particular, old growth, open-grown white oaks persist along the esker glacial deposits that traverse the property. There are two main savanna areas. The first are the areas located within the existing conservation easement. Some work has been done to restore these areas, but the restoration potential in these areas is very high. Upon inspecting the property, there was a carpet of shooting star and penn sedge with scatterings of Wisconsin state threatened kittentails (Besseya bullii).

Shrub Carr & Wet Meadow

Surrounding the esker savanna remnants are shrub carr communities that have developed on wet soils associated with the stream corridor which transects the property. Dominant species include sandbar willow (Salix interior), black willow (Salix nigra), red osier dogwood (Cornus stolonifera), and nannyberry (Viburnum lentago). These areas vary from diverse understory of native sedges (Carex sp.) to areas with reed canary grass Based on historical aerial photography, these communities have developed after the site reverted from row cropping, then pasture, to its current fallow state. There are some high quality wetlands and sedge complexes and native plant communities. 

Please join us for this unique tour. The Glacial Prairie Chapter has accepted the conservation easement for this property and we would like you to come see it. Please RSVP to Alice Mirk at so we can estimate for food and beverages. Or if you have questions.
