California State Responsibility Areas

CAL FIRE has a legal responsibility to provide fire protection on all State Responsibility Area (SRA) lands, which are defined based on land ownership, population density and land use. For example, CAL FIRE does not have responsibility for densely populated areas, incorporated cities, agricultural lands, or lands administered by the federal government. The SRA dataset provides areas of legal responsibility for fire protection, including State Responsibility Areas (SRA), Federal Responsibility Areas (FRA), and Local Responsibility Areas (LRA). SRA designations undergo a thorough 5 year review cycle, as well as annual updates for incorporations/annexations, error fixes, and ownership changes (automatic changes that do not require Board of Forestry approval). This service represents the latest official version, and is updated when new versions are released. As of April 9th, 2026, this represents SRA 26_1. Changes from SRA25_2 include acquisitions and disposals of federal lands transmitted through the yearly California Wildfire Coordinating Group (CWCG) Direct Protection Area (DPA) agreement process, from city annexations and de-annexations, from changes in county parcel boundaries, as well as corrections to any data errors discovered during the editing process.加利福尼亚州消防局（CAL FIRE）负有法定职责，为所有州责任区域（State Responsibility Area, SRA）内的土地提供消防保护。上述区域的划定依据土地所有权、人口密度与土地利用类型。举例而言，CAL FIRE无需负责人口稠密区域、自治市、农业用地，或由联邦政府管理的土地。本SRA数据集收录了法定消防责任区域的范围，包括州责任区域（SRA）、联邦责任区域（Federal Responsibility Area, FRA）与地方责任区域（Local Responsibility Area, LRA）。SRA的划定需经历完整的五年审核周期，同时每年还会针对行政区划新设、区域并入、错误修正以及所有权变更（无需州林业委员会批准的自动变更）开展更新。本服务提供的为最新官方版本，将在新版本发布时同步更新。截至2026年4月9日，本数据集对应SRA 26_1版本。相较于SRA 25_2版本，本次更新内容包括：通过年度加州野火协调小组（California Wildfire Coordinating Group, CWCG）直接保护区域（Direct Protection Area, DPA）协议流程划转的联邦土地收购与处置、城市区域的并入与剥离、县级地块边界变更，以及编辑过程中发现的所有数据错误修正。
