Description: This feature class combines Potential Range and Observed Range. Species range, as defined in this mapping effort, is the geographic area in which a species regularly occurs within Washington, including areas used for breeding as well as important distinct foraging, wintering, or migration areas where appropriate. Range does not include accidental, infrequent, or peripheral areas that are disconnected from the regularly occurring area or wintering or migration areas that are generally broad and nonspecific (Appendix B, SWAP 2015). This species Observed Range was compiled from occurrence observation data. Range is represented as a polygon(s), with boundaries derived from Hydrologic Units (HUC 12, U.S. Department of Agriculture, Natural Resources Conservation Service).
