State Natural Areas Program

COVID-19 Update

On Friday, May 1 and at the direction of Gov. Evers, the department will reopen state parks, forests and sites within the Lower Wisconsin State Riverway with special conditions. Four State Natural Areas will remain closed: Parfrey's Glen, Pewits Nest, Gibraltar Rock and Dells of the Wisconsin River. All Wildlife Areas and Fisheries Areas remain open. For more information, please visit the DNR's COVID-19 information webpage for the full list of conditions, including hours of operation, admission fees and more.

SNA Program logo State natural areas (SNAs) protect outstanding examples of Wisconsin's native landscape of natural communities, significant geological formations and archeological sites. Encompassing 402,000 acres on lands owned by the state and its many partners, including land trusts, local and county governments, and private citizens, Wisconsin's natural areas are valuable for research and educational use, the preservation of genetic and biological diversity and for providing benchmarks for determining the impact of use on managed lands. They also provide some of the last refuges for rare plants and animals.

State Natural Areas protect the very best of Wisconsin’s flora, fauna and native landscapes, from wildflower-studded prairies to towering old-growth forests, and from boggy wetlands to Great Lakes dunes. Dozens of these special places are located within State Park boundaries and are worth the effort to seek them out.
