AntelopeMigrationDesignatedSubletteWGFDCorridor

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与野生动物管理局（WGFD）编辑的、基于统计方法生成的多边形数据集，其原始数据源自对萨布利特羚羊种群管理单元（PR401）内415只迁徙羚羊采集的GPS项圈数据。 本数据集共纳入9项独立的GPS项圈研究，项圈部署范围覆盖从大提顿国家公园一路向南至80号州际公路的区域。 数据采集时段为2002年至2025年。 针对该GPS数据，研究团队采用300米线缓冲区分析法区分高、中、低三种利用强度，并通过布朗桥运动模型（BBMM）识别停歇点，最终生成基于羚羊从冬季栖息地向夏季栖息地（及返程）的移动路径，以及其沿途停留时长的多边形数据。 因WGFD在土地利用规划工作中需与各类土地管理机构协同，原始数据经编辑以提升实地可操作性。 注：构成完整廊道数据集的其他要素类（Feature Class，FCs）均采用相同的元数据内容。
