State Natural Areas Program

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 over 373,000 acres, Wisconsin's 673 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.

This course will also provide information about further training and burn contractors, but is not designed to prepare you to serve as a burn boss or conduct burns on your own. Participants will also be invited to observe a burn at a later date. Read the flyer for details [PDF].
