Desert Pocket Mouse Range - CWHR M093 [ds910]

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）是一套面向加州本土野生动物的综合性信息系统与预测模型，CWHR分布范围矢量数据集正是该系统的组成部分之一。 CWHR系统的开发旨在为涉及加州陆生脊椎动物的栖息地保护与管理、土地利用规划、影响评价、科普教育及科学研究提供支撑。该系统收录了加州常态化栖息的野生脊椎动物的生活史特征、管理现状、地理分布以及栖息地关联等信息。 分布范围图展示了各物种在加州境内当前的最大地理分布范围。此类分布图最初由物种专项专家以1:500万比例尺编绘完成，后续逐步以1:100万比例尺进行修订更新。 如需了解CWHR的更多信息，请访问其官方网页：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，包括：现有分布范围图查找表（涵盖物种代码、物种名称及分布图修订历史）、全套CWHR地理信息系统（Geographic Information System）数据集、各物种分布范围图或生活史说明的PDF文件，以及一份用户指南。
