Sierra Nevada Conservancy Subregions

Boundary Sierra Nevada Conservancy (SNC) boundary. The boundary was mapped to correspond with statute AB 2600 (2004) and as re-defined in SB 208 (2022). Work on the boundary was completed by CalFire, GreenInfo Network, and the California Department of Fish and Game. Meets and bounds description of the area as defined in statute: PRC Section 33302 (f) defines the Sierra Nevada Region as the area lying within the Counties of Alpine, Amador, Butte, Calaveras, El Dorado, Fresno, Inyo, Kern, Lassen, Madera, Mariposa, Modoc, Mono, Nevada, Placer, Plumas, Shasta, Sierra, Siskiyou, Tehama, Trinity, Tulare, Tuolumne, and Yuba, described as the area bounded as follows: On the east by the eastern boundary of the State of California; the crest of the White/Inyo ranges; and State Routes 395 and 14 south of Olancha; on the south by State Route 58, Tehachapi Creek, and Caliente Creek; on the west by the line of 1,250 feet above sea level from Caliente Creek to the Kern/Tulare County line; the lower level of the western slope’s blue oak woodland, from the Kern/Tulare County line to the Sacramento River near the mouth of Seven-Mile Creek north of Red Bluff; the Sacramento River from Seven-Mile Creek north to Cow Creek below Redding; Cow Creek, Little Cow Creek, Dry Creek, and up to the southern boundary of the Pit River watershed where Bear Creek Mountain Road and Dry Creek Road intersect; the southern boundary of the Pit River watershed; the western boundary of the upper Trinity watershed in the County of Trinity; on the north by the boundary of the upper Trinity watershed in the County of Trinity and the upper Sacramento, McCloud, and Pit River watersheds in the County of Siskiyou; and within the County of Modoc, the easterly boundary of the Klamath River watershed; and on the north in the County of Modoc by the northern boundary of the State of California; excluding both of the following: (1) The Lake Tahoe Region, as described in Section 6605.5 of the Government Code, where it is defined as "region" (2) The San Joaquin River Parkway, as described in Section 32510. According to GreenInfo Network and the California Department of Fish and Game, the blue oak woodland used to define a portion of the Sierra Nevada Conservancy's western boundary was delineated using referenced vegetation and imagery data. Subregions “Subregions” means the six subregions in which the Sierra Nevada Region is located, described as follows: (1) The northwest Sierra subregion, comprising the Counties of Shasta, Siskiyou, Tehama, and Trinity.

Wildlife Movement Barriers - CDFW [ds2867]

CDFW divides the state into six administrative Regions. CDFW staff in each Region identified linear segments of infrastructure that currently present barriers to wildlife populations in their jurisdiction. In doing so, the Regions used all available empirical information in their possession, including existing connectivity and road crossing studies, collared-animal movement data, roadkill observations, and professional expertise. This dataset represents all barriers identified statewide as of June 2024 and former barriers that have been remediated since 2020. This dataset represents CDFW's ongoing effort to identify priority wildlife movement barriers across the state. Currently, increasing attention is being directed toward wildlife habitat connectivity as a mechanism of maintaining biodiversity in the face of population growth and climate change. Listing priority wildlife barrier locations will help focus limited financial resources where the highest need has been identified to improve wildlife movement. This is complementary to CDFW’s fish passage barrier priorities that have been identified for anadromous fish. Like the fish passage priorities, the wildlife barrier priorities list will be periodically updated to reflect new information and barrier removal successes. Most of the barriers identified are highway segments, but other infrastructure types such as fencing, canals, local roads, and high speed rail alignments are also represented.

Vegetation - Lava Beds National Monument - 2019 [ds2859]

The geographic information system (GIS) format spatial data set of vegetation for the Lava Beds National Monument (LABE) vegetation mapping and inventory project was created for the National Park Service (NPS) Vegetation Mapping Inventory Program (VMIP). The project area covers over 18,936 ha (46, 792 acres). The map classification scheme used to create the vegetation data set is designed to represent local vegetation types at the finest level possible using the National Vegetation Classification Standard (NVCS) Version 2. The associations present in each map unit are also coded into the database. Vegetation plot sampling was conducted to describe the associations and to develop the map classification scheme. A total of 169 vegetation plots were sampled at LABE. A detailed vegetation analysis of these data was undertaken along with historic information to develop the map classification scheme, in accordance with the National Vegetation Classification Standard (NVCS) Version 2. The vegetation data set was developed by interpreting 2009 NAIP aerial imagery and extensive field surveys. The project report for the LABE vegetation mapping project provides details pertaining to the methods of the vegetation sampling, classification, and mapping. The vegetation data are distributed as an ESRI format file geodatabase, stored in Universal Transverse Mercator zone 10 mapping coordinates, North American Datum 1983. The vegetation map consists of 582 polygons. 65 of these polygons were 100% dominated by one vegetation type, the rest were interpreted to be a mix of two vegetation types. The percent cover attribute for the primary and secondary (if present) vegetation in each polygon was estimated from photographic and field evidence. In addition, the occurrence of up to two associations and their percent cover were identified as composing the primary and secondary vegetation. The minimum mapping unit of each polygon is 0.5 hectares. Identified secondary map units within each polygon were intermixed at a scale below the minimum map unit. Vegetation types were crosswalked to MCV, CalVeg, and CWHR types by CDFW's Vegetation Classification and Mapping Program (VegCAMP). For the purpose of crosswalking, only the primary map unit was used. The mapping report is available from the document library here: [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=235741] The report is also bundled with the dataset, which can be downloaded from BIOS here: https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/2800_2899/ds2859.zip

Foothill Yellow-legged Frog Clade Boundaries [ds2865]

Foothill Yellow-legged Frogs (Rana boylii) are currently recognized as a California Species of Special Concern, a non-regulatory designation intended to focus attention on animals at conservation risk, stimulate research on poorly known species, and achieve conservation and recovery of these animals before they meet criteria for listing as threatened or endangered under the California Endangered Species Act (CESA; Fish and G. Code, § 2050 et seq.). Under the California Code of Regulations, Title 14, Section 670.5, the following FYLF designations have been made: Southwest/South Coast, West/Central Coast, and East/Southern Sierra clades are Endangered; Northeast/Northern Sierra and Feather River clades are Threatened. The Northwest/North Coast clade is not listed under the California Endangered Species Act but retains the status of California Species of Special Concern. California Fish and Game Commission Notice of Findings for FYLF: [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=177905]. Additionally, the Foothill Yellow-legged Frog throughout its range in California and Oregon is currently under review by the U.S. Fish and Wildlife Service for listing as threatened or endangered under the federal Endangered Species Act.

Black Rockfish Mean Density - North Central Coast - 2010-11 - PISCO [ds1358]

This map service is a synthesis of the baseline characterization of kelp and shallow rock ecosystems inside and outside of several North Central Coast (NCC) MPAs at the time of their implementation. MPAs in the NCC study region (NCCSR) were implemented on May 1, 2010. Baseline characterizations were conducted by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) between August and October of 2010 and 2011. Visual SCUBA surveys took place at sites within MPAs and at their associated reference sites (sites outside MPA) to establish quantitative baselines for measuring future MPA effects (i.e., changes in community structure due to MPA implementation). This particular map service focuses on PISCO's characterization of fish communities aimed at estimating fish densities and fish size distribution. Refer to the following link for specifics regarding PISCO's “fish survey design” and “fish sampling methodology”: [http://www.piscoweb.org/research/science-by-discipline/ecosystem-monitoring/kelp-forest-monitoring/subtidal-sampling-protoco#FishSurvey]. Surveys for baseline characterization of kelp forest communities focused on the following MPAs: Point Arena SMR; Sea Lion Cove SMCA; Saunders Reef SMCA; Del Mar SMR; Stewarts Point SMR/SMCA; and Salt Point SMCA. From Point Arena to Salt Point, 35 cells (fundamental sampling units) were sampled via fish transects (inside and outside of MPAs) using stratified sampling across shore and at various depths in the kelp forests (5m, 10m, 15m and 20m). Utilizing PISCO's GPS coordinates of the 35 study cells (points), and details from PISCO's methods (see link above), we created estimated footprints of the areas in which these transects were surveyed (the 35 fundamental sampling units). From there, we also estimated the aggregated site polygons (aggregate sampling units) that comprise either an MPA or an MPA reference site; this resulted in 12 new polygons that were representative of the kelp and shallow rock ecosystems surveyed by PISCO. Stewarts Point SMR and SMCA are combined in the survey summaries to make up one of the ‘aggregate sampling units’ and therefore those feature classes have 11 instead of 12 features. These estimated study areas (fundamental and aggregate sampling units) were then used to synthesize and represent PISCO's fish survey results into the following map service product. The map service is a conglomeration of fish density and fish length metrics for the regions most abundant rockfish and non-rockfish species.

Southern Torrent Salamander Range - CWHR A005 [ds1134]

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.

Administrative Maps

The California State Lands Commission (CSLC) was created by the California Legislature in 1938 and given the authority and responsibility to manage certain public lands within the state. The public lands under the Commission’s jurisdiction are of two distinct types—sovereign lands acquired upon California’s admission into the Union in 1850; and certain federally granted lands including school lands, and swamp and overflowed lands. For purposes of this GIS data, sovereign lands are considered to be further divided into two general categories—fixed-boundary sovereign lands and ambulatory-boundary sovereign lands. The following lands are included in this data: Portions of the ambulatory-boundary for state sovereign lands at a specific point in time, for portions of the San Joaquin River. NOT INCLUDED IN THIS DATA: School lands: These are what remains of nearly 5.5 million acres throughout the state originally granted to California by Congress in 1853 to benefit public education. Fixed-boundary sovereign lands: These are sovereign, public trust lands having fixed boundaries as the result of land exchanges, boundary line agreements or court orders. Swamps and overflowed lands: These are what remain of federal lands granted to California by Congress in 1850 to encourage reclamation and development of agricultural lands. ALSO NOT INCLUDED IN THIS DATA: Ownership details within the U.S. Government meanders of Owens Lake. THIS DATA SUPERSEDES all previously published GIS information with respect to the above described state-owned lands under the jurisdiction of the CSLC.
California CIR 2005 1m

Color infrared (CIR) imagery acquired during NAIP 2005 flights. The source CIR 1-meter resolution imagery was purchased from the North West Group (NWG) by three state agencies (California Dept. of Fish and Game, California Dept. of Transportation, and California Dept. of Water Resources). No access constraints, but there are use constraints. CIR coverage was not available in all areas. THIS CIR IMAGERY IS NOT A NAIP PRODUCT. Band1=NearIR, Band2=R, Band3=G. This service is offered by the California Department of Fish and Wildlife (CDFW). For more information about CDFW map services, please visit: [https://wildlife.ca.gov/Data/GIS/Map-Services]
California CIR 2005 NDVI 1m

A Normalized Differential Vegetation Index (NDVI) was applied to the source 2005 1-meter resolution color infrared (CIR) imagery. NDVI=(NearIR-Red)/(NearIR+Red). The color ramp (produced by ESRI) goes from brown (less healthy vegetation) to red to green (healthier vegetation or more "greenness"). Lack of statewide color balancing of the source CIR imagery shows inconsistencies in NDVI results between adjacent areas. No access constraints, but there are use constraints (see source product metadata). The source color infrared (CIR) imagery was acquired during NAIP 2005 flights. The imagery was purchased from the North West Group (NWG) by three state agencies (California Dept. of Fish and Game, California Dept. of Transportation, and California Dept. of Water Resources).
