American Badger Range - CWHR M160 [ds912]

Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for California's wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000. For more information about CWHR, visit the CWHR webpage (https://www.wildlife.ca.gov/Data/CWHR). The webpage provides links to download CWHR data and user documents such as a look up table of available range maps including species code, species name, and range map revision history; a full set of CWHR GIS data; .pdf files of each range map or species life history accounts; and a User Guide.CWHR分布范围矢量数据集是加州野生动物栖息地关系（California Wildlife Habitat Relationships, CWHR）系统的组成部分之一；该系统是一套面向加州陆生脊椎动物的综合性信息系统与预测模型。CWHR系统的开发旨在为加州陆生脊椎动物相关的栖息地保护与管理、土地利用规划、环境影响评价、科普教育及科学研究提供支撑。CWHR系统收录了已知在加州常态化分布的野生动物物种的生活史特征、保护管理现状、地理分布格局及栖息地关联关系等核心信息。分布范围矢量图展示了各物种在加州境内当前的最大地理分布范围，该类地图最初由物种级专家以1:500万比例尺完成边界勾绘，后续逐步修订为1:100万比例尺的版本。如需了解CWHR系统的更多详情，请访问其官方网页：https://www.wildlife.ca.gov/Data/CWHR。该网页提供了CWHR相关数据与用户文档的下载链接，具体包括涵盖物种代码、物种名称及分布范围地图修订历史的可用分布范围地图查找表，全套CWHR地理信息系统（Geographic Information System, GIS）数据，各物种分布范围地图或物种生活史说明文档的PDF文件，以及官方用户指南。
