White-Headed Woodpecker Range - CWHR B305 [ds1552]

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.

Vegetation - Ballona Wetlands [ds2966]

California Department of Fish and Game (DFG) ecologists conducted field reconnaissance for this project and Santa Monica Bay Restoration Commission assisted with field data collection. Under contract to the DFG, GreenInfo Network digitized a fine-scale vegetation map of the Ballona Wetlands Ecological Reserve (BWER). The mapping study area consists of approximately 600 acres within Ballona Wetlands Ecological Reserve of Los Angeles County, California. CNPS under separate contract and in collaboration with California Department of Fish and Wildlife VegCAMP developed the floristic vegetation classification used for the project. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). This map study was initiated to assist in restoration planning for the Ballona Wetland Enhancement Project, which aims to restore and enhance native habitats on BWER and provide public access and recreational opportunities. The primary purpose of CDFW’s goal of developing fine-scale digital vegetation maps is part of the California Biodiversity Initiative Roadmap of 2018. The mapping study area consists of approximately 600 acres within Ballona Wetlands Ecological Reserve of Los Angeles County, California. Reconnaissance was conducted by CDFW ecologists on May 9-11, 2006 to collect a preliminary list of vegetation types to accurately represent the study area. On June 13, 2006, I.K. Curtis Aerial Photography took a true color orthophoto at 1-foot pixel resolution (±1:16,800) under contract to the Coastal Conservancy and Brad Henderson (CDFW) combined the preliminary vegetation list to manually draw polygons overlaid the air photo. GreenInfo used the drawing and air photo for a digitized map draft of polygons to be verified and assessed by field crews for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes on June 19-22, 2007. Field crews noted 8 exotic, invasive species in the map polygons worthy of special interest in regards to restoration planning decisions. Field reconnaissance enhanced map quality. There was a total of 61 mapping classes. No accuracy assessment of this map has been performed because ecologists visited every polygon in the field.

Common Gartersnake Range - CWHR R061 [ds1767]

CWHR species range datasets represent the maximum current geographic extent of each species within California. Ranges were originally delineated at a scale of 1:5,000,000 by species-level experts more than 30 years ago and have gradually been revised at a scale of 1:1,000,000. Species occurrence data are used in defining species ranges, but range polygons may extend beyond the limits of extant occurrence data for a particular species. When drawing range boundaries, CDFW seeks to err on the side of commission rather than omission. This means that CDFW may include areas within a range based on expert knowledge or other available information, despite an absence of confirmed occurrences, which may be due to a lack of survey effort. The degree to which a range polygon is extended beyond occurrence data will vary among species, depending upon each species’ vagility, dispersal patterns, and other ecological and life history factors. The boundary line of a range polygon is drawn with consideration of these factors and is aligned with standardized boundaries including watersheds (NHD), ecoregions (USDA), or other ecologically meaningful delineations such as elevation contour lines. While CWHR ranges are meant to represent the current range, once an area has been designated as part of a species’ range in CWHR, it will remain part of the range even if there have been no documented occurrences within recent decades. An area is not removed from the range polygon unless experts indicate that it has not been occupied for a number of years after repeated surveys or is deemed no longer suitable and unlikely to be recolonized. It is important to note that range polygons typically contain areas in which a species is not expected to be found due to the patchy configuration of suitable habitat within a species’ range. In this regard, range polygons are coarse generalizations of where a species may be found. This data is available for download from the CDFW website: [https://www.wildlife.ca.gov/Data/CWHR]. The following data sources were collated for the purposes of range mapping and species habitat modeling by RADMAP. Each focal taxon’s location data was extracted (when applicable) from the following list of sources. BIOS datasets are bracketed with their “ds” numbers and can be located on CDFW’s BIOS viewer: [https://wildlife.ca.gov/Data/BIOS]. * California Natural Diversity Database, * Terrestrial Species Monitoring [ds2826], * North American Bat Monitoring Data Portal, * VertNet, * Breeding Bird Survey, * Wildlife Insights, * eBird, * iNaturalist, * other available CDFW or partner data.

California Public Schools 2025-26

This layer serves as the authoritative geographic data source for California's TK/K-12 public school locations for the 2025-26 academic year. Schools are mapped as point locations and assigned coordinates based on the physical address of the school facility. The school records are enriched with additional demographic and performance variables from the California Department of Education's (CDE) data collections. These data elements can be visualized and examined geographically to uncover patterns, solve problems and inform education policy decisions. The schools in this file represent a subset of all records contained in the CDE's public school directory database. This subset is restricted to TK-12 public schools that were open in October 2025 to coincide with the official 2025-26 student enrollment counts collected on Fall Census Day in 2025 (first Wednesday in October). This layer excludes nonpublic schools and district office schools, so the total public school enrollment in this file will differ from the CDE's official statewide Fall 1 Census Day total enrollment. CDE's official Fall 1 2025-26 public school enrollment (5,731,260) - nonpublic school enrollment (8,645) - district office school enrollment ( 5,917) = 5,716,698. The CDE's [California School Director]y provides school location other basic school characteristics found in the layer's attribute table. The school enrollment, demographic and program data are collected by the CDE through the California Longitudinal Achievement System (CALPADS) and can be accessed as publicly downloadable files from the [Data & Statistics] web page on the CDE website. Schools are assigned X, Y coordinates using a quality controlled geocoding and validation process to optimize positional accuracy. Most schools are mapped to the school structure or centroid of the school property parcel and are individually verified using aerial imagery or assessor's parcels databases. Schools are assigned various geographic area values based on their mapped locations including California County Superintendents Educational Services (CCSESA) district numbers, state and federal legislative district identifiers and National Center for Education Statistics (NCES) locale codes.
Hazardous Waste Tracking System - Active Facilities

The Hazardous Waste Tracking System (HWTS) is the Department of Toxic Substances Control's data repository for hazardous waste Identification (ID) numbers and manifest information. Contained in this data is locational information for all inactive HWTS facilities, their types (Generator, Transporter or Treatment, Storage and Disposal), creation date, name and EPA ID. Updated 2026-07-11 05:03:31
Tier 2 High Hazard Zones (HHZ)

This layer, in combination with Tier 1 High Hazard Zones, was used to generate the final Combined High Hazard Zones dataset. Tier 2 High Hazard Zones were updated in 2025. Tier 2 High Hazard Zones represent areas for forest health restoration and fire planning. They were composed from the combination of ranked watersheds, FHSZ, and wildfires from 2012 forward (outlined below). Please see the Reference Layers for these input layers; their metadata contain further details about the methods by which they were created. Tier 2 High Hazard Zone Inputs: Watersheds: Areas with elevated tree mortality and high fire threat that are a hazard to public safety, community assets, and related infrastructure represent the primary focus of these zones. CAL FIRE mapped Tier 2 High Hazard Zones through a risk assessment model that scored watersheds based on prevalence of hazards and the amount of asset to be protected. This used the National Hydrography Dataset Watershed Boundaries (WBD) hydrologic unit code (HUC) 12 watersheds; these are the smallest consistently delineated watersheds in California and average around 24,000 acres in this model. The hazards utilized were: number of dead trees (from the USFS Aerial Detection Survey, 2015), acres of Tier 1 High Hazard Zones, and fire threat -- represented in the Sierra Nevada by WHRTYPE and fire return interval departure (USFS FRID, 2014) and in other areas of the state by CAL FIRE's Fire threat layer (FRAP, 2005). The assets to be protected were: amount of critical Infrastructure, represented by roads, communities, recreation facilities, communications); water related natural resources (represented statewide by acres of riparian and in the Sierra Nevada by acres of riparian and montane meadows); and amount of water infrastructure, represented by water conveyances, and water storage facilities. Each hazard and each asset was scored individually, and an overall composite score was achieved. The overall scores for hazard and assets were ranked and then also combined for an overall score. For more information on the datasets used and the scoring methodology, please contact calfire.egis@fire.ca.gov. These zones may be periodically updated to reflect new mortality or infrastructure assets at risk. Wildfire Perimeters: As of 2020, Tier 2 also includes wildfire perimeters from 2012 to the present publish date. Starting with 2021, only fires over 100 acres are included. Fire Hazard Severity Zone: As of 2020, Tier 2 also includes "High" and "Very High" Fire Hazard Severity Zones in forested areas. -------- Emergency Declaration: On October 30, 2015 Governor Brown issued an emergency declaration requiring public agencies to identify areas of tree mortality that hold the greatest potential to result in wildfire and/or falling trees and threaten people and property in these areas. Once identified, these areas will be prioritized for removal of dead and dying trees that present a threat to public safety.
