RPBB_County_Range_060925

This map shows the current and historical range of the rusty patched bumble bee. The current range is determined by counties with observations in 2007 or later while counties making up the historical range are primarily based on observations made prior to 2007. Additionally, the conservation unit in which each county is located is indicated in the attribute table. Conservation units are determined by the rusty patched bumble bee Recovery Plan which describes recovery criteria that need to be met in order for the species to be removed from the endangered species list and the actions that need to be implemented in order to meet the criteria. Recovery criteria and actions are specific to each conservaiton unit. This map will help inform and focus recovery for the species at broader spatial scales.本地图展示了锈斑熊蜂（rusty patched bumble bee）当前与历史的分布范围。其当前分布范围由2007年及之后有观测记录的县级行政区确定，而构成历史分布范围的县级行政区则主要基于2007年之前的观测数据。此外，属性表（attribute table）中标注了每个县级行政区所属的保护单元（conservation unit）。保护单元的划定依据《锈斑熊蜂恢复计划》，该计划明确了该物种从濒危物种名录中移除所需满足的恢复标准，以及为达成这些标准需实施的各项配套措施。恢复标准与对应措施因各保护单元而异。本地图将有助于在更广阔的空间尺度上，为该物种的恢复工作提供决策支撑并明确工作重心。
