CPW Ring-necked Pheasant Shapefile Download

Updated December, 2025 CONCENTRATION AREA: Areas within the overall range where pheasant densities are at least 200% greater than in the surrounding overall range. OVERALL RANGE: An area that encompasses all known activity areas within the observed range of a pheasant population. 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 集中区域（CONCENTRATION AREA）：指整体范围内野鸡种群密度较周边整体范围至少高出200%的区域。 整体分布范围（OVERALL RANGE）：指涵盖某一野鸡种群观测范围内所有已知活动区域的范围。 本数据集信息源自科罗拉多公园与野生动物局（Colorado Parks and Wildlife）野外工作人员。数据通过使用不同比例尺的地形图与美国国家农业影像计划（NAIP）影像，经智能交互白板（SmartBoard Interactive Whiteboard）数字化采集获得，引用来源为：Cowardin, M., M. Flenner. 2003年3月. Maximizing Mapping Resources. 《GeoWorld》16(3):32-35。本数据集采用四年轮换更新机制，每年更新科罗拉多公园与野生动物局下辖四个区域中的一个，不会在全州范围内每年进行更新。
