What does this data set describe?

Title: Wild and Scenic River (WSR) Corridors in Alaska
Abstract:
This dataset contains the polygons of Wild and Scenic River (WSR) Corridors in Alaska. WSR data is based on the "Administrative Large Parcel Boundaries" dataset produced by the AK Department of Natural Resources and River Management Plans. Inholding information was obtained from the Native Allotment dataset.
