CPW Wild Turkey Shapefile Download

Updated December, 2025 OVERALL RANGE: The area which encompasses all known seasonal activity areas within the observed range of a population of wild turkeys. PRODUCTION AREA: Those area(s) that are used by turkeys for nesting during the period from March 15 to August 15. Human activity should be restricted in these areas during this period. ROOST SITES: Ponderosa pine and cottonwood trees of at least 10" dbh used by turkeys for diurnal and nocturnal perches. WINTER CONCENTRATION: That part of the winter range where densities are at least 200% greater than the surrounding winter range density. WINTER RANGE: That part of the overall range where 90% of the individuals are located from November 1 to April 1 during the average five winters out of ten. 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.更新时间：2025年12月 1. 总活动范围（OVERALL RANGE）：涵盖某野生火鸡种群观测范围内所有已知季节性活动区域的地域范围。 2. 筑巢区域（PRODUCTION AREA）：火鸡于每年3月15日至8月15日期间用于筑巢的区域。此期间该区域内应限制人类活动。 3. 栖息位点（ROOST SITES）：胸径（dbh）不小于10英寸的黄松与棉白杨，作为火鸡日间与夜间的停留栖息处。 4. 冬季聚集区（WINTER CONCENTRATION）：冬季活动范围内火鸡种群密度较周边冬季活动区域密度高出至少200%的区域。 5. 冬季活动范围（WINTER RANGE）：指总活动范围中，在十年平均有五个冬季的11月1日至次年4月1日期间，90%的火鸡个体分布于此的区域。 本数据集由科罗拉多州公园与野生动物管理局（Colorado Parks and Wildlife）野外工作人员采集获取，通过SmartBoard交互式电子白板，依托不同比例尺的地形图与国家农业影像计划（NAIP）影像完成数字化描边生成（文献引用：Cowardin, M., M. Flenner. 2003年3月. Maximizing Mapping Resources. GeoWorld 16(3):32-35）。 本数据集采用四年一轮转的更新机制，每年更新科罗拉多州公园与野生动物管理局下辖四个区域中的一个区域数据，并非每年对全州范围的数据进行整体更新。
