U.S. Fish and Wildlife Service, Region 3 Ecological ServicesThis data layer was created to delineate the approximate boundaries of areas important to monarch butterfly populations across the contiguous United States. These boundaries were created as part of a species status assessment (SSA) done by the US Fish and Wildlife Service. Different monarch populations, or different portions a population's range, may have different conservation needs. These ranges will be used to distinguish and prioritize needs across the range of monarch butterflies. The intended display scale for this file is 1:500,000. The boundary information is for visual display at appropriate small scales only. Cartographic boundary files should not be used for geographic analysis including area or perimeter calculation. Files should not be used for determining precise geographic area relationships.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/738307d1097d42bdb2651d7b35ed32d4_0engU.S. Fish and Wildlife Service Open DataPublicMonarch Butterfly US Conservation Units [United States]Web servicesUnited StatesLast Modified: 2024-04-18
