WI Dept. of Natural Resources The Nature Conservancy Kettle Moraine Land Trust Waukesha County Land Conservancy

The mission of the Oak Savanna Alliance (OSA) is to promote the protection, restoration, and awareness of oak savannas on public and private lands in the greater Southern Kettle Moraine area.

OSA is a partnership of government, local conservation groups, and private landowners interested in preserving Oak Savannas and increasing awareness of this rare natural community.

Oak openings now share equal billing with tallgrass prairies as the most threatened in the world. Intact examples of oak savanna vegetation are now so rare that less than 500 acres exist in Wisconsin. This is less than 0.01% of the original 5.5 million acres.

Our Goals:

Identify, preserve and protect high quality examples of oak savanna in the Southern Kettle Moraine Region.

  • Inventory areas for high quality sites
  • Focus land acquisition and easements
  • Develop resources for private land owners
  • Encourage appropriate zoning for protection

Manage existing and restore degraded Oak Savanna in the Southern Kettle Moraine Region.

  • Develop guidelines for private land owners
  • Explore grants to expand management
  • Promote prescribed fire as a management tool

Educate the public and local decision makers about Oak Savannas and benefits of preservation.

  • Provide information
  • Encourage research
  • Develop partnerships
  • Link people with web based resources
