The Protected Undisturbed Lands layer contains polygon features representing undisturbed lands that have a permanent protection status. It is a subset of the Potentially Undisturbed Lands layer (mn_pudl), and is created by intersecting the undisturbed lands layer with an aggregate layer of lands that are known to be permanently protected. Undisturbed land polygons were mapped at a scale of 1:8000 or greater over the entire Prairie Coteau and Lac qui Parle landscapes in Southwestern Minnesota. The project extent is defined by the layer: mn_pudl_cntyextent. Each polygon is classified as either undisturbed grassland or undisturbed woodland according to a rigorous, repeatable, systematic protocol. Permanently protected lands include an aggregate of fee title and easement holdings by a variety of state, federal, and private non-profit agencies and organizations.
