,This dataset provides an estimate of terrestrial landscape intactness, (i.e. condition), based on the extent to which human impacts such as agriculture, urban development, natural resource extraction, and invasive species have disrupted the landscape across the State of California. Terrestrial intactness values are high in areas where these impacts are low. This dataset, updated April 2025, is the most recent version created for CAL FIRE using the open-source logic modeling framework Environmental Evaluation Modeling System (EEMS). Spatially-explicit logic modeling hierarchically integrates numerous and diverse datasets into composite layers, quantifying information in a continuous rather than binary fashion. This technique yields accessible decision-support products that agencies can use to craft scientifically-rigorous management strategies. The analysis was carried out at 1 sq. km resolution.The California Statewide Landscape Intactness model integrates data from many different sources: agriculture development (from FRAP Vegetation, and CDL Cropscape), urban development (from LANDFIRE EVT and NLCD Impervious Surfaces), polluted areas (from NHD treatment ponds and EPA Superfund and Brownfield sites), linear development (OHV routes from owlsheadgps.com, roads from TIGER (broken down by type), utility lines, railroads, and pipelines from various state and BLM sources), point development (communication towers from the FCC), energy and mining development (from the state’s Office of Mine Reclamation mine dataset, larger mine footprints, state geothermal wells, USGS wind turbines, solar footprints, renewable projects in development, oil refineries and state oil/gas wells), planned clear cuts from Statewide Timber Harvest Plans, invasive vegetation (compiled from multiple sources including LANDFIRE EVT and USGS INHABIT), and measures of natural vegetation fragmentation. Input data range in currency from 2011-2024; the majority of data portray the more recent condition of the landscape. Results apply to terrestrial areas only. (Water bodies are omitted from the final dataset.) Online interactive maps showing the intactness model’s input data, intermediate layers, and final results can be explored via the Conservation Biology Institute’s platforms EEMS Online and Data Basin.Caution is warranted in interpreting this dataset because it provides a single estimate of terrestrial intactness based on available data. The degree of terrestrial intactness likely varies for a particular species or conservation element and may depend on additional factors or thresholds not included in this model. This model should be taken as a general measure of intactness that can serve as a template for evaluating across many species at the ecoregion scale, and provides a framework within which species-specific parameters can be incorporated for more detailed analyses.Work funded by the California Department of Forestry and Fire Protection ( CAL FIRE ), Fire and Resource Assessment Program ( FRAP ).,

,The current dataset is appropriate for displaying the overall pattern of WUI development at the county level, and comparing counties in terms of development patterns. Until the dataset is refined through a field review and quality assurance process, it is not suited for WUI designations for individual houses or neighborhoods.,The data can be downloaded as a file geodatabase here: GIS Mapping and Data Analytics | CAL FIRE,Three WUI classes are mapped:,Wildland Urban Interface – dense housing adjacent to vegetation that can burn in a wildfire,,Wildland Urban Intermix - housing development interspersed in an area dominated by wildland vegetation subject to wildfire, and,Wildfire Influence Zone - wildfire susceptible vegetation up to 1.5 miles from Wildland Urban Interface or Wildland Urban Intermix.,Wildland Urban Interface, Wildland Urban Intermix, and Wildfire Influence Zones. The model uses residential structure density and vegetative cover to define areas within the Fire Hazard Severity Zones.,Primary Data Inputs:,Secondary Data Inputs:(used to determine vegetation dominance),Fire Hazard Severity Zones: This source raster dataset represents Fire Management Analysis Zones as adopted officially on April 1, 2024 for State Responsibility Area (SRA) and as distributed to local governments in February and March of 2025 for Local Responsibility Areas (LRA). The source data for the LRA release also contains FHSZ coverage for Federal Responsibility Areas, but these data are used to fill out the state for assessment purposes only. Data sources: FHSZALL_v25_1 (SRA Approved and LRA Recommended) Statewide_v17_4 (Federal Responsibility Areas),Housing unit density classes for California derived from 30-m rasters extracted from Wildfire Risk to Communities: Spatial datasets of wildfire risk for populated areas in the United States and reprojected to California Teale Albers NAD87.,DEN4 Description,,,After classifying, clusters of DEN4 values less than 80 cells (just under 18 acres) were nibbled to the nearest adjacent DEN4 class.,State Wildland Zones and Canopy Cover: State Wildland Zones are used to determine the dominance of vegetation. Areas which would otherwise be classed as Wildland Urban Interface.area reclassed to Intermix if the vegetation cover is 50% or more. These canopy cover data are used in concert with SALO Canopy Cover to determine vegetation dominance in areas both within and outside of the the extent of the wildland zones.,Note: Vegetation dominance is determined as either FHSZ Wildland Zone 1-3 or SALO > 50% cover. A 3X3 cell circular focal mean is applied and areas with 0.5 or greater are considered at least 50% vegetated.,-----------------------------------------------------------------,These data are analyzed according to the following parameters:,Interface:,Intermix:,Interface and Intermix are then combined. After combining, any cell group with fewer than 80 cells is classed to the value of its neighbor.,Influence Zone:,Interface, Intermix and Influence Zones are then combined. After combining, any cell group with fewer than 80 cells is classed to the value of its neighbor.,A final step in the model addressed an inadvertent error invoked by the processing of potential interface conversion to Intermix for small fragments (<20 acres of Interface) and larger areas of Interface that were covered by a majority (>50%) vegetation within the areas otherwise defined as Interface because of meeting housing unit density and hazard requirements. When these lands were then subject to the final size minimum of 100 acres they then reverted to being potential buffer areas. This was remedied by selecting all lands that met the criteria of DEN4 values 3 and 4 (i.e.,all areas with housing density greater than 1 HU/ac) and reverting them to Interface designation. These previously eliminated but now reverted Intermix areas did not meet the 100 acre requirement and did not produce additional buffer zone influence areas from them. In most

,This version of the base exclusions incorporates the latest draft version of the Protected Area Layer (Solar) and the techno-economic exclusion layer. The base exclusions form the fundamental exclusion set that the additional planning priorities of the Core Land Use Screen is added to. The merged footprints of these primary two layers are modified by the Greater Sage-Grouse Habitat Management Areas, the Bureau of Land Management Desert Renewable Energy Conservation Plan (DRECP) Land Use Plan Amendment (LUPA) Development Focus Areas (DFAs), Variance Process Lands (VPL), and the General Public Lands (GPL), as well as the 2024 BLM Western Solar Plan. These areas allow for renewable energy applications and are therefore exempt (erased) from the base exclusions layer, even if the protected area layer or techno-economic exclusion layer identified the area as an exclusion. The DFAs are partitioned by technology type so that only the DFAs that allow solar energy are applied in this modification.,The area of California remaining after removing the base exclusions is called the resource potential basemap. It forms the starting point (or base) used in renewable resource estimation and defines where environmental and land-use datasets can be applied in exploring implications of renewable resource development.,Note: Existing project footprints are also included as part of the base exclusions.,More information is found in the CEC presentation from the August 19 webinar, as well as the 2023 Land Use Screens Staff Report in the CEC Energy Planning Library. ,

,The geospatial data reflected in this Protected Area Layer contain minor data versioning and consolidation updates from the previous Protected Area Layer. The components of the Protected Area Layer mostly pertain to natural and wilderness areas where development of utility-scale renewable energy is prohibited, and were heavily based on RETI 1.0 blackout areas.,The protected area layer for solar PV technology includes the BLM Western Solar Plan, as well as the latest Greater Sage-Grouse Habitat Management Areas (note: the Sage Grouse Habitat Management Areas provide separate exclusion areas for solar, wind, and geothermal resources).,More information is found in the CEC presentation from the August 19 webinar, as well as the 2023 Land Use Screens Staff Report in the CEC Energy Planning Library. ,

,The State of California, Department of Developmental Services oversees and organizes services for individuals with developmental disabilities in California. This is achieved through a network of 21 non-profit, community-based agencies called regional centers. These regional centers are responsible for evaluating individuals, determining their eligibility for services, and providing case management. The Regional Center Catchment Areas were developed to capture the extent of services associated with a regional center. This data, when added to the DDS Regional Center Lookup helps current and future consumers of the DDS Regional Center services in determining which Regional Center to contact according to their location within an associated catchment (service) area. When an address is entered into the Regional Center Lookup application, a zonal search of the catchment area and the address location returns the appropriate Regional Center name and a link with contact information.
