AntelopeMigrationIdentifiedSubletteCorridorStopoverAreas

These data represent the WGFD-edited version of statistically-based polygons derived from GPS collar data collected from 415 antelope migrating in the Sublette antelope herd unit (PR401). There were nine different GPS collar studies that contributed to this data set which included collaring efforts from Grand Teton National Park all the way south to Interstate 80. The data were collected from 2002 through 2025. The GPS data were analyzed using Line Buffer (300 meter) for the high, medium and low use levels and Brownian Bridge Movement Model (BBMM) for stopovers, which produced polygons based on where animals traversed from winter range to summer range (and back) and how much time they spent along the way. The original data were edited to be more manageable on the ground as the WGFD works with land management agencies during land use planning. NOTE: The same metadata content is used for the other FCs comprising the entire corridor dataset.本数据集为经怀俄明州鱼类和野生动物局（WGFD）编辑的统计衍生多边形数据，其原始数据采自萨布利特羚羊群管理区（PR401）内415只迁徙羚羊的GPS项圈（GPS collar）监测数据。共有9项独立的GPS项圈监测研究为该数据集提供了数据支撑，研究覆盖范围从大提顿国家公园（Grand Teton National Park）一路向南延伸至80号州际公路（Interstate 80）。数据采集时段为2002年至2025年。针对该GPS监测数据，研究团队采用300米线缓冲区（Line Buffer）方法划分高、中、低三种使用强度等级，并结合布朗桥运动模型（Brownian Bridge Movement Model, BBMM）分析动物停歇点位；上述分析基于羚羊从冬季活动区到夏季活动区（及返程）的移动路径及其沿途停留时长生成了对应多边形数据。鉴于怀俄明州鱼类和野生动物局（WGFD）在土地利用规划工作中需与各土地管理机构协同作业，原始数据已完成编辑以提升实地应用的便捷性。注：构成完整廊道数据集的其余FCs均采用相同的元数据内容。
