MNDNR Forest Inventory Old Growth

This layer is a digital inventory of currently designated or candidate old growth forest stands on lands administered by the Department of Natural Resources (DNR). This data originates from the Inventory Module of the Minnesota DNR's 4Trees System. Old growth forest designations are determined through an interdisciplinary evaluation process by DNR staff in divisions of Forestry, Fish and Wildlife, Ecological and Water Resources, and Parks and Trails. These data are updated on a continuous basis, as needed.<br/><br/>Also included is the old growth Special Management Zone (SMZ), a 330-foot buffer around the Old Growth layer.
