The Wisconsin Geological and Natural History Survey (WGNHS) was created by the Wisconsin Legislature in 1897. It is the descendant of earlier state surveys in Wisconsin, which date back to 1854.

Survey is defined to include resource inventory as well as basic and applied research and analysis. WGNHS has no specific regulatory or enforcement responsibilities.
