BIOS is an online map viewer designed to enable the management, visualization, and analysis of biogeographic data collected by the California Department of Fish and Wildlife (CDFW) and partner organizations. BIOS facilitates the sharing of those data within CDFW as well as with the public. BIOS integrates GIS, relational database management, and ESRI's ArcGIS Server technology to create a statewide, integrated information management tool that can be accessed via the Internet.

CDFW BIOS GIS Dataset, Contact: Michael Hardy, Description: This dataset represents barriers to terrestrial wildlife movement in California, as identified by the California Department of Fish and Wildlife (CDFW) in May 2022.

CDFW BIOS GIS Dataset, Contact: VegCAMP Vegetation Classification and Mapping Program, Description: The 17,158 acre Johnson Valley project area is located in San Bernardino County, 32 miles east of Victorville, CA bisected by highway 247. The fine-scale vegetation map was created as part of a collaborative project between the United States Geological Survey (USGS) and the Vegetation Classification and Mapping Program of the California Department of Fish and Wildlife (CDFW) to show the correlation between vegetation and geomorphology.

The Biological Resources Inventory (BRI) consists of 17 related tables, covering biological groupings (fish, invertebrates, plants, terrestrial vertebrates and even habitats), properties, data sources, and survey types. For each biological grouping, there are two tables. One lists all the species within an organismal grouping expected to occur in California (or in the case of habitats, all the habitat types expected to occur in California). The other links to a given species (in its respective organismal grouping) or habitat from the first table with a property number, and in some cases, provides further information about such details as the abundance, season and survey type. As expected there is also a table that links the property numbers used throughout the database with the actual property name. Our research indicates that this list of property names and numbers may not be up to date, nor reflect the names and property numbers used in the current lands inventory (more information about the Lands Inventory is available from Sharon Taylor, Lands Program- Sharon.Taylor@wildlife.ca.govor 916-323-7194). There are also several supporting tables that provide information about interpreting the codes used for abundance, season and survey type. While there are many entries in the BRI, most lack information about who, how, when and why they were obtained. We know data was collected from many sources and ranges in quality from first person direct observations made by CDFW personnel and partners, to regional bird and plant lists, to land management plans, to predicted occurrences from one of several nascent iterations of the California Wildlife Habitat Relationships program.Because of this variation, and our inability to understand the provenance or verify the accuracy of the data, we felt it prudent to only include the highest quality data from the BRI in the Biogeographic Information and Observation System (BIOS). This dataset is a subset of the information contained in the BRI database. It consists of direct observations made by CDFW staff or partners of fish, invertebrates, plants, terrestrial vertebrates and habitats from the BRI.While this is the best and likely most useful data contained in the BRI, we still have little supplemental information about the nature of these direct observations (date of observation, observer, reason for study or survey etc.), and as such urge the user to exercise caution in interpreting these data.

CDFW BIOS GIS Dataset, Contact: Melanie Gogol-Prokurat, Description: CWHR Predicted Habitat Suitability. This dataset represents areas of suitable habitat within the species ranges based on California Wildlife Habitat Relationships (CWHR 2016) and a statewide best-available vegetation map (FVEG2015, FRAP 2015).

Geodatabase feature class containing a map of vegetation within the Great Valley Ecoregion produced by the Geographical Information Center (GIC) at CSU Chico. The dataset combines both new mapping and the previously completed Central Valley Riparian and Sacramento Valley and the Southern San Joaquin Valley vegetation maps. Vegetation polygons were manually digitized as interpreted using the National Agricultural Inventory Program's (NAIP) 2009 (Central Valley Riparian and Sacramento Valley map), 2012 (Southern San Joaquin Valley map) and 2014 (balance of San Joaquin Valley) aerial imagery at a scale of 1:2000. The minimum mapping unit (mmu) for natural vegetation is 1.0 acre, with a minimum average width of 10 meters. The mmu for agricultural and urban polygons is 10 acres. Vegetation is attributed to the Group and Alliance level of the state and national vegetation hierarchy. In some cases, polygons were attributed only to Group or Macrogroup level when the Alliance could not be determined from photointerpretation. The map classification is based on the key to vegetation types in Buck-Diaz et al. 2012. The Central Valley and Sacramento Valley maps were assessed for Accuracy with an average users’ accuracy of 90.2 percent and users’ accuracy of 89 percent. The San Joaquin Valley portion of the map was field verified by the mappers but was not otherwise assessed for accuracy (see Supplemental Information below for details). More information can be found in the project report, which is bundled with the vegetation map published for BIOS here: https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/2600_2699/ds2632.zip.

CDFW BIOS GIS Dataset, Contact: CWHR California Wildlife Habitat Relationships, Description: 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.

CDFW BIOS GIS Dataset, Contact: FAB Financial Assistance Branch, Description: This data contains summary information for Disadvantaged ($56,982) and Severely Disadvantaged ($42,737) communities. The thresholds are derived from American Community Survey 2014-18 (ACS 2014-18) 5-year estimates at the census tract geographic level and the California State Median Household Income of $71,228.

CDFW BIOS GIS Dataset, Contact: Heather Rustigian-Romsos, Description: The California Department of Transportation (Caltrans) and California Department of Fish and Game (CDFG) commissioned the California Essential Habitat Connectivity Project because a functional network of connected wildlands is essential to the continued support of California's diverse natural communities in the face of human development and climate change.

CDFW BIOS GIS Dataset, Contact: Kristeen Penrod, Description: The critical need for conserving landscape linkages first came to the forefront of conservation thinking in California in November 2000, when a statewide interagency workshop was convened at the San Diego Zoo. Entitled "Missing Linkages: Restoring Connectivity to the California Landscape" the workshop brought together over 200 land managers, conservationists, and biologists to discuss and map critical and at-risk habitat linkages throughout the state. A total of 232 linkages were identified.

CDFW BIOS GIS Dataset, Contact: VegCAMP Vegetation Classification and Mapping Program, Description: In 2008 Aerial Information Systems, Inc. (AIS) was contracted to produce a vegetation map for the northern Sierra Nevada Foothills region, here defined by the two northern subsections of the Sierra Nevada Foothills Section of the USDA Ecological Subregions of California (Miles and Goudey 1997). This includes 2.48 million acres of land, with approximately 15% under public ownership and 85% under private ownership.
