Chukar Range - CWHR B132 [ds920]

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.加州野生动物栖息地关系（California Wildlife Habitat Relationships, CWHR）是一套面向加州野生动物的综合信息系统与预测模型，CWHR范围分布图矢量数据集是其组成部分之一。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、影响评估、科普教育及科学研究提供支撑。CWHR收录了加州境内已知常态化栖息的野生动物物种的生活史、管理现状、地理分布及栖息地关联等信息。范围分布图展示了各物种在加州境内当前的最大地理分布范围，该类分布图最初由物种领域专家以1:500万比例尺划定，后续逐步更新为1:100万比例尺的修订版本。如需了解CWHR的更多详情，请访问CWHR官方网页（https://www.wildlife.ca.gov/Data/CWHR）。该网页提供了CWHR数据与用户文档的下载链接，相关文档包括：涵盖物种代码、物种名称及分布图修订历史的可用分布图查询表；全套CWHR地理信息系统（GIS）数据；各物种范围分布图或物种生活史说明的PDF文件；以及官方用户指南。
