What Makes Gasser Sand Barren Special

Gasser Sand Barrens is situation on part of an old terrace of the Wisconsin River; it lies just southwest of the moraines marking the maximum southern extent of the Pleistocene glaciation, placing it within the famous Driftless Area. Although the Driftless Area escapted at least the later advances of the continental glaciers, glacial activity has greatly affected the Sauk Prairie area through the deposition of outwash, creating a rolling terrain with sandy soil. 

Because its soil is sandy and susceptible to rapid depletion of nutrients, the site was abandoned for cultivation purposes in the 1930s, and native species were able to recolonize most of the area. 

How was Gasser Sand Barren Protected

The Nature Conservancy acquired the site in 1969 as a gift from the Gasser family who had farmed the adjacent land for over 100 years. The Prairie Enthusiasts then took over ownership and management of Gasser Sand Barren in 2006.

How You Can Help Gasser Sand Barren
