The dataset is a feature class showing the boundaries of 515 groundwater basins and subbasins as defined by the California Department of Water Resources (Bulletin 118, 2003). The file is in ESRI geodatabase format and is intended for use with compatible GIS software. Groundwater basins are represented as polygon features and designated on the basis of geological and hydrological conditions - usually the occurrence of alluvial or unconsolidated deposits. When practical, large basins are also subdivided by political boundaries, as in the Central Valley. Basins are named and numbered per the convention of the Department of Water Resources. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR GIS Spatial Data Standards. DWR makes no warranties or guarantees, either expressed or implied, as to the completeness, accuracy or correctness of the data, nor accepts or assumes any liability arising from or for any incorrect, incomplete or misleading subject data. The official DWR GIS Data Steward for this dataset is Brett Wyckoff, who may be contacted at 916-651-9283, or at brett.wyckoff@water.ca.gov. Comments, problems, improvements, updates, or suggestions should be forwarded to the official GIS Data Steward as available and appropriate.</span>

Biological Resources Inventory (BRI) Direct Observations - CDFW [ds2672]

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.

These features were added to the landslide deposits mapped in USGS Publication MF-1790, &quot;Geologic Map of the Late Cenozoic Deposits of the Sacramento Valley and Northern Sierran Foothills, California&quot; (Helley and Harwood,1985). This data set was created by scanning the five- original sheets from USGS Publication MF-1790 (Helley and Harwood, 1985), the five sheets were georeferenced individually and the geologic information was digitized using AutoCAD 2006. The accuracy of the digitized lines was deemed to be within acceptable error tolerances, with the digitized lines accurately matching the original drafted lines in USGS Publication MF-1790 (Helley and Harwood, 1985). In general, the width of the contact lines on the paper copy, accounting for scale, ranged up to about 20 meters (66 feet). During the original digitization, minor topological mistakes (such as identical rock units on both sides of a lithologic contact or unclosed polygons) and omissions (such as unidentified lithologic units) were applied according to the best available knowledge. Comparisons were made between the original mylar and colorized field sheets (as available), in addition to the Geologic Map of the Battle Creek Fault Zone, Northern Sacramento Valley, California (USGS Map MF-1298, 1981), the Geologic Map of the Chico Monocline and Northeastern Part of the Sacramento Valley, California (USGS Miscellaneous Investigations Series Map I-1238, 1981), and the Geologic Map of the Red Bluff 30' X 60' Quadrangle, California (USGS Geologic Investigation Series Map I-2542, 1995). The correlation and description of geologic units were excerpted from USGS Publication MF-1790m (Helley and Harwood, 1985).</span><br /></p></div>

A related table of timeseries data is provided that corresponds to each of these point locations. Timeseries data reflect a simulation period from 10/31/1921 through 9/30/2003 as simulated by the CalSim II model. Multiple CalSim II model simulations are included to reflect projected changes in climate for early-century (2030) and late-century (2070) model simulations (including 2070 drier extreme warming [DEW] scenario and wetter moderate warming [WMW] scenario). Spatial references were developed during the Water Storage Investment Program (WSIP) climate change study conducted in 2016. The user should use caution and fully understand the limitations of these datasets before applying them in a water budget calculation as these datasets correspond to model simulation outputs that contain their own assumptions and limitations.</span>

Black Bear Habitat Model for NSNF Connectivity - CDFW [ds1008]

The Maxent modeling algorithm was used to build the species distribution model at 270 m spatial resolution using species occurrence points and environmental layers as predictors (Phillips et al. 2006). Species occurrence points were primarily obtained from CNDDB (California Natural Diversity Database) and other CDFW sources, GBIF (Global Biodiversity Information Facility), PRBO (Point Blue Conservation Science) and Arctos museum databases. Vegetation, distance to water, elevation, and bioclimatic variables (Franklin et al. 2013) were used as predictor variables. The models were run at 270 m spatial resolution with five replications using cross-validation as a method of sample evaluation. Cross-validation involved the partitioning of the sample data into n subsets, fitting the models to n-1subsets, and testing the model on the one subset not used in fitting the model. Initial model runs showed that our models converged around 2,000 iterations and for this reason we ran all models with 2,500 maximum iterations. Maxent was implemented in R using the ‘dismo''package (Hijmans et al. 2011). Model evaluation was carried out using the ‘PresenceAbsence''package in R (Freeman &amp; Moisen 2008). We used AUC as a metric to evaluate model performance. The package also computes threshold values using several accuracy metrics to translate predicted probability maps into binary suitable and unsuitable habitats. We selected the MeanProb, a threshold set based on the mean predicted probability of species occurrences. The output from Maxent are grid datasets in a multiband ‘tif''format with one band for each replication. We averaged the five replicated maps and created a mean grid for each species. The grid was then symbolized to represent low (threshold-50), medium (50-75) and high (75-100) habitat suitability, with pixel values that are below the threshold excluded. Models were reviewed by CDFW species experts; please review the use limitations.For more information see the project report at [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=85358].
