CPW Sagebrush Vole Shapefile Download

Updated December, 2025 SagebrushVoleOverallRange is an ESRI shapefile encompassing the observed and predicted range of a population of Sagebrush Vole in Colorado. Sagebrush Vole is primarily associated with sagebrush habitats, especially where big sagebrush co-dominates with native bunchgrasses. Most experts consider the sagebrush vole a sagebrush obligate. This information was derived from Colorado Parks and Wildlife field personnel. Data was captured by digitizing through a SmartBoard Interactive Whiteboard using topographic maps and NAIP imagery at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). These data are updated on a four year rotation with one of the four Colorado Parks and Wildlife Regions updated each year. These data are not updated on a statewide level annually.2025年12月更新的《灌丛田鼠总体分布范围》（SagebrushVoleOverallRange）为ESRI形状文件（ESRI shapefile），涵盖科罗拉多州境内灌丛田鼠（Sagebrush Vole）种群的实测与预测分布范围。灌丛田鼠主要栖息于灌丛生境，尤其多见于大灌丛与本土丛生草类共优的区域。多数专家将灌丛田鼠视为灌丛专性物种。本数据集的信息源自科罗拉多州公园与野生动物局（Colorado Parks and Wildlife）的野外工作人员。数据通过智能交互白板（SmartBoard Interactive Whiteboard）数字化采集，依托不同比例尺的地形图与NAIP影像完成制图（Cowardin, M., M. Flenner. 2003年3月。《最大化制图资源》。《GeoWorld》16(3):32-35）。该数据集采用四年轮换更新机制：科罗拉多州公园与野生动物局下辖的四个区域每年更新其中一个区域的数据，而非每年对全州范围的数据集进行更新。
