California Towhee Range - CWHR B484 [ds1645]

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.
Terrestrial Connectivity - ACE [ds2734]

For more information, see the Terrestrial Connectivity Factsheet at [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=150835]. The California Department of Fish and Wildlife’s (CDFW) Areas of Conservation Emphasis (ACE) is a compilation and analysis of the best-available statewide spatial information in California on biodiversity, rarity and endemism, harvested species, significant habitats, connectivity and wildlife movement, climate vulnerability, climate refugia, and other relevant data (e.g., other conservation priorities such as those identified in the State Wildlife Action Plan (SWAP), stressors, land ownership). ACE addresses both terrestrial and aquatic data. The ACE model combines and analyzes terrestrial information in a 2.5 square mile hexagon grid and aquatic information at the HUC12 watershed level across the state to produce a series of maps for use in non-regulatory evaluation of conservation priorities in California. The model addresses as many of CDFWs statewide conservation and recreational mandates as feasible using high quality data sources. High value areas statewide and in each USDA Ecoregion were identified. The ACE maps and data can be viewed in the ACE online map viewer, or downloaded for use in ArcGIS. For more detailed information see [https://www.wildlife.ca.gov/Data/Analysis/ACE] and [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=24326].

Map Sheet 48 (2025 update) - Annualized Earthquake Loss

Map data were provided by Dr. Jaiswal (U.S Geological Survey, USGS), leading author of the joint FEMA-USGS report “Hazus Estimated Annualized Earthquake Losses for the United States”. The report provides nationwide and state-by-state estimates of AELs based on the latest census and building stock data, as well as USGS earthquake hazard information. The AELs presented here are the estimated long-term value of earthquake losses to the general building stock in any single year in a specified geographic area (e.g., state, county, metropolitan area). They are economic losses from earthquake shaking-related building damage. They do not include losses from ground-failure effects such as landslide, liquefaction, surface fault rupture, or losses due to other secondary effects such as fires following earthquakes due to lack of a nationally consistent database. Building economic losses are direct economic losses including structural damage, non-structural damage, and content damage; as well as building damage-related economic losses, such as inventory loss, relocation cost, loss of proprietors’ income, and rental income loss. These do not include losses associated with business interruption. Replacement costs and loss valuations are based on 2023 dollars.
Map Sheet 48 (2025 update) - Preferred Slip Rate Values on Major Faults in California

This map shows fault-based earthquake sources and their preferred slip rates used in the USGS 2023 conterminous U.S. time-independent earthquake rupture forecast model, which provides authoritative estimates of the magnitude, location, and time-averaged frequency of potentially damaging earthquakes in California. Fault model slip rates are given in millimeters per year. The shapefile depicts the surface traces of modeled faults, which are simplified from the CGS USGS Quaternary Fault and Fold database (https://www.usgs.gov/programs/earthquake-hazards/faults/). For modeled blind fault seismic sources, the traces represent the map-view fault tip projection of the subsurface fault. For additional information regarding modeled faults please refer to Hatem et al. (2022).
Map Sheet 48 (2025 update) - Site Condition

This map shows distribution of the time-averaged shear-wave velocity in the upper 30 m (Vs30) for California. Vs30 is used as a proxy for local geologic site condition in ground motion hazard calculations. The map is produced using data provided by Thompson (ver. 2.0, July 2022), which is based on the method described by Thompson and others (2014) with adjustments (see Thompson, 2022 for detail). Vs30 unit is m/s. Data resolution is 3 arcseconds (approximately 90 m). Due to software limitations, symbology cannot be added to this service. To match the symbology used in the [MS48 Additional Maps application], use the following configuration: * Esri Color Ramp: Yellow to Dark Red * Number of Classes: 5 * Classes & Hex Codes: * 176.1 - 300: #F4FE93 * 300 - 450: #F6DC6A * 450 - 600: #F2B841 * 600 - 725: #BA671A * 725 - 1,473.3: #810A01
Vegetation - Eastman and Hensley Lakes [ds1057]

The California Native Plant Society (CNPS) Vegetation Program produced a vegetation map and classification for approximately 35,000 acres including the town of Raymond and extending to Eastman Lake to the west, and surrounding Hensley Lake to the south (Madera and Mariposa Counties, California). CNPS delineated vegetation polygons using 2012 NAIP aerial imagery and CNPS survey data collected between 2008 to 2010, as well as field reconnaissance in 2014. The mapped area includes mostly private lands, as well as the properties adjacent to Eastman and Hensley Lakes which are managed by the Army Corps of Engineers. The vegetation classification of 47 native vegetation alliances and semi-natural stands was based on data within the southern Sierra Nevada Foothills Ecoregion across a larger area of approximately 300,000 acres including portions of Mariposa, Madera, and Fresno Counties. The vegetation map resulted in 31 types of mapping units including alliance-level vegetation types from the floristic classification within the focused study area. More information can be found in the mapping report, which is bundled with vegetation map published for BIOS here: [https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/1000_1099/ds1057.zip] The report can also be downloaded separately here: [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=101387].
Vegetation - Slinkard and Little Antelope Wildlife Area [ds2940]

The California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation map of Slinkard Valley and Little Antelope Valley Wildlife Areas in Mono County, California. The vegetation classification was derived from data collected in the field during the periods August 28-31, 2017, September 10-14, 2018, and November 5-9, 2018. Vegetation polygons were drawn using heads-up “manual” digitizing using the 2016 National Agricultural Imagery Program (NAIP) true color and color infrared (CIR) 1-meter resolution data as the base imagery. Supplemental imagery included NAIP true color and CIR 1-meter resolution data from 2009-2012, BING imagery, and current and historical imagery from Google Earth. The minimum mapping unit (MMU) is 1 acre, with the exception of wetland and riparian types, which have an MMU of ½ acre. Mapping is to the National Vegetation Classification System (NVCS) hierarchy association, alliance, or group level based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data. Field accuracy assessment surveys were collected by CDFW regional and VegCAMP staff in the fall of 2019. It was determined that the map had an overall accuracy of 89.3% before suggested adjustments were made to typing and line-work in response to the accuracy assessment. As part of the mapping process for this project we also implemented a drone component. The purpose was to test the use of drone photos to enhance and extend reconnaissance efforts for mapping, help with determining signatures on coarser imagery, use images taken above surveys as a check on cover estimates, and test whether drone imagery would allow for mapping herbaceous vegetation at a finer scale.

Vegetation - Garcia River Forest [ds722]

Aerial Information Systems, Inc. (AIS) was contracted by the Nature Conservancy to create a vegetation map covering approximately 23,800 acres (~37 square miles) of the Garcia River Watershed east of Point Arena in Mendocino County. The vegetation map adheres to the 2008 National Vegetation Classification Standard (NVCS) and the Manual of California Vegetation (MCV). One-meter National Agricultural Inventory Program (NAIP) imagery flown in July of 2005 was used as a base for the delineated polygons and photo interpretation signature. Two trips were taken in July and August of 2007 for reconnaissance. The vegetation units were then interpreted across the entire study area using heads-up digitizing techniques through custom tools developed in the Arc GIS 9.2 Software that were enhanced by AIS.As a general rule, common and widespread vegetation units were delineated down to a minimum mapping unit (MMU) of approximately ½ hectare. Small wetlands and forest openings were delineated in several incidences below the MMU. The report can be found here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=41130
