The Management Units Land Feature Class defines general management units on Refuge system lands. The boundary of these units may or may not differ from related management unit boundaries (grazing, fire, wetland etc.). If only a single set of management units exist for a National Wildlife Refuge or Wetland Management District, they should be defined here. This data is managed by the National Wildlife Refuge System. Individual features and attributes are the responsibility of managing stations and their regions. This data is current to December 31, 2025.
