Belted Kingfisher Range - CWHR B293 [ds1541]

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联系统（California Wildlife Habitat Relationships, 简称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分布区矢量数据集是该系统的组成部分之一。该系统的开发初衷是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、环境影响评估、科普教育及科学研究提供支撑。CWHR收录了已知定期栖息于加州的各类野生动物物种的生活史特征、管理现状、地理分布及栖息地关联关系等信息。分布区地图用于展示各物种在加州境内当前的最大地理分布范围，此类地图最初由物种专家以1:500万比例尺绘制，后逐步以1:100万比例尺完成修订更新。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数据与各类用户文档的下载链接，包括可用分布区地图查询表（含物种代码、物种名称及分布区地图修订历史）、完整的CWHR地理信息系统（Geographic Information System，简称GIS）数据集、各分布区地图或物种生活史说明的PDF文件，以及《用户指南》。
