Ancient Murrelet Range - CWHR B243 [ds1511]

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.
Black Bear Range - CWHR M151 [ds792]

For more information about the CWHR system, visit the CWHR Homepage: https://www.wildlife.ca.gov/Data/CWHR. 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.
Vegetation - Delta Vegetation and Land Use Update - 2016 [ds2855]

The Sacramento-San Joaquin Delta Reform Act of 2009 established the Delta Stewardship Council (DSC) to achieve more effective governance while providing for the sustainable management of the Delta ecosystem and a more reliable water supply, using an adaptive management framework. Vegetation and land use are mapped for the 737,621 acres constituting the Legal Delta portion of the Sacramento and San Joaquin River Delta area. The current effort produced a digital map covering 737,621 acres considered to be the Legal Delta Area. 2016 National Agricultural Imagery Program (NAIP) 1-meter resolution imagery was used to delineate line work and attribute polygons. The 2019 map is a re-map of the 2007 effort. This map retained the line work and attributes of the 2007 mapping when static and was amended in areas where change occurred. Change detection was done comparing 723,426 acres, which were identical in the 2007 (2005 base imagery) and 2019 (2016 base imagery) efforts. GIC utilized the key produced for the 2007 mapping effort, in conjunction with the 2009 Central Valley key, as well as the CNPS membership rules online to determine classification levels and vegetation communities. Vegetation mapping is to alliance level when possible, otherwise it is left at group level (based on the National Vegetation Classification Standard, see [http://biology.usgs.gov/npsveg/nvcs.html]); land use is mapped to Anderson Level 2 classification (see [https://pubs.usgs.gov/pp/0964/report.pdf]). The map classification is based on a vegetation classification derived from field data collected in summer and fall of 2005 produced by the Vegetation Classification and Mapping Program (VegCAMP) of the Department of Fish and Wildlife. Membership rules for each alliance can be found at http://vegetation.cnps.org/. 2016 National Agricultural Inventory Program (NAIP) one meter orthoimagery was the baseline imagery used. Google Earth imagery was used as supplemental imagery. Natural vegetation comprises approximately 17% of the Delta study area, 65% is agriculture and pasture, 10% is urban/other and 8% is open water. The minimum mapping unit was 250 acres (100 ha). Link to download report: [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=174866].
Vegetation - Modoc Plateau Applegate Areas - 2016 [ds2858]

The mapping study area was divided into two areas of Modoc and Lassen Counties. The Applegate area consists of approximately 84,574 acres, and work was performed on the project between 2017 and 2021. The Eagle Lake area, consists of approximately 66,402 acres in Lassen County, and Work was performed on the project between 2019 and 2021. The eastern portion of the Applegate area used the 2016 NAIP imagery as a base and the Eagle Lake and western portion of Applegate area were mapped using the 2018 NAIP imagery. The vegetation classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on new surveys and classification work conducted in collaboration with CDFW VegCAMP. The map was produced applying heads-up digitizing techniques using a base of one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 1 acre; exceptions are made for wetlands and riparian types, which were mapped to a 1/4 acre MMU. Field reconnaissance and accuracy assessment enhanced map quality. There were a total of 91 classes mapped in the Applegate area. The overall Fuzzy Accuracy Assessment ratings for the final vegetation map at the Alliance level were 92.2 percent at the 60-100% Correct or Acceptable level, and 86.4 percent at the 80-100% Correct or Acceptable level. At the Association level, the Fuzzy Accuracy Assessment ratings were was 88.1 percent at the 60-100% Correct or Acceptable level, and 79.1 percent at the 80-100% Correct or Acceptable level. For the Eagle Lake area, there were a total of 78 mapping classes. The overall Fuzzy Accuracy Assessment ratings for the final vegetation map at the Alliance level were 86.3 percent at the 60-100% Correct or Acceptable level, and 81.9 percent at the 80-100% Correct or Acceptable level. At the Association level, the Fuzzy Accuracy Assessment ratings were was 84.0 percent at the 60-100% Correct or Acceptable level, and 72.4 percent at the 80-100% Correct or Acceptable level.
