The difference between a proclaimed boundary and an administrative boundary is as follows:
1) The proclaimed boundary portrays the official Forest boundary as defined by an Act of Congress. A grassland does not have a proclaimed boundary. Spatially, what is portrayed as a grassland proclaimed boundary may be referred to instead as an "external" boundary.
2) An administrative boundary portrays the limits of authority of a given Forest Supervisor's office. Several National Forest & Grasslands are often managed as a combined unit (example: Arapaho, Roosevelt National Forests & Pawnee National Grassland are managed as one administrative unit).
