Elk Range - CWHR M177 [ds945]

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范围图矢量数据集是针对加州野生动物的综合信息系统与预测模型——加州野生动物栖息地关系（California Wildlife Habitat Relationships，简称CWHR）的组成部分之一。CWHR系统旨在为加州境内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。该系统收录了加州境内定期出现的野生脊椎动物物种的生活史特征、保护管理状况、地理分布以及栖息地关联等信息。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，最初由物种专项专家以1:500万比例尺手绘勾绘，后续逐步修订为1:100万比例尺的版本。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数据集与各类用户文档的下载链接，包括可用范围图查询表（涵盖物种代码、物种名称及范围图修订历史）、全套CWHR地理信息系统（Geographic Information System，GIS）数据、各范围图或物种生活史说明的PDF文件，以及《用户指南》。
