WSA_ARC: This data set represents Wilderness Study Area (WSA) boundaries as inventoried in the mid1980's and defined in the October 1991 "Wilderness Study Report". Wilderness Study Areas are essentially roadless areas under BLM jurisdiction. Wilderness Study Areas have special management restrictions and priorities. They are a one-time designation and new WSA or additions to WSA are rare. For a complete description of this data consult the Wilderness Study Areas Spatial Data Standard. http://www.blm.gov/or/datamanagement/index.php

WLD_CHAR_ARC: This theme represents the results of an inventory of wilderness characteristics found, or not found, on BLM lands in Oregon and Washington. This data set shows the lines for polygons for areas found to possess wilderness characteristics, plus boundary lines for those areas that were intensively inventoried and found to not meet minimum wilderness criteria. All BLM lands outside of designated Wilderness Areas and Wilderness Study Areas are periodically evaluated for wilderness characteristics based on meeting minimum criteria for size, naturalness and outstanding opportunities for solitude or primitive and unconfined recreation. Where such inventories have been updated, those BLM lands not depicted by polygon lines were deemed to clearly lack wilderness characteristics in an initial scan of size and roadlessness to determine areas warranting more intensive inventory.

LWC_MNGMNT_POLY: This polygon feature represents the spatial extent and boundaries of BLM Lands with Wilderness Characteristics with management decisions. This dataset also also provides BLM and the public with information about naturalness, opportunities for solitude and/or primitive recreation, supplemental values and proximity to Wilderness Areas or Wilderness Study Areas.
