CPW Dwarf Shrew Shapefile Download

Updated December, 2025 DwarfShrewOverallRange is an ESRI shapefile encompassing the observed and predicted range of a population of Dwarf Shrew in Colorado. Dwarf Shrew is primarily associated with mountain habitats, mostly reported in rocky habitats in the alpine tundra and subalpine coniferous forests but also found in dry brushy slopes in Colorado around 1,670 m. This information was derived from species experts. A variety of data capture techniques were used including implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). Various sources were referenced in developing these data including Mammals of Colorado, and CPW Scientific Collection data. 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月更新的矮鼩鼱全域分布数据集（DwarfShrewOverallRange）为ESRI形状文件（ESRI Shapefile），涵盖了科罗拉多州境内矮鼩鼱种群的实测分布与预测分布范围。矮鼩鼱主要依附山地生境，多数记录见于高山苔原与亚高山针叶林的岩生生境，同时在科罗拉多州海拔约1670米的干燥灌丛坡地亦有发现。本数据集的信息均由物种专家提供。本次数据采集采用了多种技术手段，包括使用智能交互白板（SmartBoard Interactive Whiteboard）开展不同尺度下的立式实时数字化制图工作（引用文献：Cowardin, M., M. Flenner. 2003年3月. 最大化制图资源. 《地理世界（GeoWorld）》16(3):32-35）。数据集开发过程中参考了多类数据源，包括《科罗拉多州哺乳动物》以及科罗拉多公园与野生动物局（CPW）科学馆藏数据。该数据集采用四年一轮的更新周期，每年仅更新科罗拉多州四个公园与野生动物管理区域中的一个，并非每年开展全州范围的更新工作。
