Description:
This dataset is used to denote USFS Land Use Designations (LUD) on the Tongass National Forest. Chapter 3, of Land and Resource Management Plan includes the complete management prescription for the 19 LUDS used in the Forest Plan. Please refer to the following document for further information:

2011 Map Errata The Tongass Forest Plan LUDs were developed using small-scale Tongass-wide Forest maps similar to those included in the map packets of the Draft and Final EISs. The level of accuracy of a map at such a scale is approximately +/- 500 feet. Enlargements of this map were also sometimes used in LUD development, but these maps contained no additional detail or accuracy; they were just larger scale. This approach is appropriate for the development of a Forest Plan map, which is a permissive, zoning map. It is the role of subsequent project planning to resolve, within the overall intent of the Forest Plan mapped LUDs, the actual location of activities on the ground. In some situations, there is a lack of precise map correlation or registration of a LUD boundary between two GIS maps. Most of these variations are minor, and are due to the combining of map covers of varying resolution. This situation results in remnants, or "slivers" of small acreages of land appearing on the maps between mapped polygons. In other situations during project planning LUD boundaries may be indefinite or illogical if located literally on the ground as depicted on the FEIS map. In some instances boundaries may appear to bisect an existing or mapped harvest unit; or, while paralleling an existing or mapped road, boundaries may appear to cross and recross the road randomly. Dealing with these types of map inconsistencies is not considered to be a "change" in the Forest Plan. These are considered to be the correction of errata on an as needed basis when it occurs during project planning or other analysis. Resolution of the occurrences discussed above will be guided by: 1. Following the physical and other identifiable on-the-ground features; 2. Consider assigning the LUD that comes nearer to maintaining the natural setting of the area; or 3. Using professional management judgement regarding the resource situation, in consultation with other agencies, with documented rationale.
