Summary

Summary of geospatial species data from the California Freshwater Species Database (Aquarius). The California Freshwater Species Database identifies the 3,906 vascular plants, microinvertebrates, and vertebrates native to California that depend on fresh water for at least one stage of their life history, evaluates their conservation status, and aggregates spatial data of their locality observations or distributions.

Description

The ranges and abundances of species that depend on freshwater habitats are declining worldwide. Efforts to counteract those trends are often hampered by a lack of information about species distribution and conservation status and are often strongly biased toward a few well-studied groups. We identified the 3,906 vascular plants, macroinvertebrates, and vertebrates native to California, USA, that depend on fresh water for at least one stage of their life history. We evaluated the conservation status for these taxa using existing government and non-governmental organization assessments (e.g., endangered species act, NatureServe), created a spatial database of locality observations or distribution information from ~400 data sources, and mapped patterns of richness, endemism, and vulnerability. Data created for that effort - the California Freshwater Species Database - are summarized within this geodatabase.

The analysis units for the summaries presented here are derived from the Watershed Boundary Database (WBD) for the United States ( http://nhd.usgs.gov/wbd.html ).

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Conceptual consistency
Measure description
ArcGIS 9.2 ArcTopology tools were used to ensure that there weren't any of the following errors: unclosed polygons, polygons with gaps, overlapping polygons, overlapping lines, lines that intersect or self-intersect, lines with dangles, and lines with pseudos. All sliver polygons were removed either using 'eliminate' or 'merge' functions in ArcToolbox. Line pseudos were merged appropriately, all dangles were removed, and all intersecting lines were split accordingly.




Data quality report - Completeness omission
Measure description
All fields for all polygons in the .pat are attributed, with the exception of the 'Hu_10_GNIS_' and 'Hu_12_GNIS_' fields, whose attributes are optional. Some polygons in the 'Ncontrb_a' field may have a '0' value. All fields for the lines in the .aat are attributed. The lines adjacent to the universal polygon are attributed with a '0' for the 'Hu_level' field. These cannot be attributed until the adjacent states complete their linework, at which point the highest level of the hydrologic unit can be determined. The WBD was produced using digital raster graphic (DRG) images as a source map. Data completeness for DRG files reflect content of the source graphic and may therefore be reflected in the completeness and accuracy of the WBD.




Data quality report - Quantitative attribute accuracy
Measure description
The accuracy of this data is dependent on both the level of detail of the source material and the interpretation procedures for capturing that source. The primary limiting factor for the level of detail of the source material is the scale (1:24,000) of the digital raster graphic (DRG). The map scale determines the level of content that may be extracted from the given source during digitization. 1) 100% of the boundary locations were visually verified using the draft 1:250,000-scale boundaries and the DRGs as a reference. Additionally, 10% of the boundary locations were reviewed by the Interagency Hydrologic Unit Group (IHUG). Local knowledge was incorporated into the draft delineations and used to verify boundary locations or digital orthophoto quads (DOQ) of the area were reviewed. 2) 100% of the 'Huc_12', 'Huc_10' and 'Huc_8' values were verified, visually, for accuracy upon attribute transfer from the 1:250,000-scale draft data, or when generated with watershed boundary dataset tools, and then again once the entire dataset was complete. The 'Huc_12' values were also checked to ensure no duplicate numbers were found. 3) 100% of the 'States' attributes were visually checked. 4) 100% of the 'Acres' values were calculated ('Shape_Area' * 0.0002471). 5) The 'Ncontrb_a' (non-contributing area) attributes were first identified during the creation of the 1:250,000-scale data. Non-contributing areas larger than 3,000 acres were attributed as 'closed' (closed basins). 100% of the non-contributing areas were verified using the DRGs during the attribution process. 6) The 'Hu_10_ds' and 'Hu_12_ds' attributes (indicating the Huc_10s and Huc_12s downstream of a hydrologic unit) were visually verified using the National Hydrographic Dataset (NHD) and, where necessary, the DRG. 7) The 'Huc_10_name' and 'Hu_12_name' attributes were checked for duplicates and to ensure that the names comply with the Federal Standards for the Delineation of Hydrologic Unit Boundaries (see http://ftp-fc.sc.egov.usda.gov/NCGC/products/watershed/hu-standards.pdf) . Hydrologic units are usually named after the most prominent or significant hydrographic feature found within the unit. 8) The 'Hu_10_mod' and 'Hu_12_mod' attributes (indicating modifications to any hydrologic unit's natural boundary location) were identified with the use of NHD, DRG, and, in some cases, DOQ or NAIP (National Agriculture Imagery Program) imagery, and manually noted during the digitizing process for each hydrologic unit. They were then transferred to the WBD and verified during the attribution process. In instances where a mod of 'OT' was used for a hydrologic unit, this was usually to indicate where local-level input was implemented in the delineation process - most notably in some US Forest Service areas, and in and around the San Francisco Bay area. For detailed descriptions of all modification types, see ftp://ftp-fc.sc.egov.usda.gov/NCGC/products/watershed/hu-standards.pdf. 9) 100% of the 'Hu_10_type' and 'Hu_12_type' attributes (indicationg a closed basin, standard watershed, frontal, etc.) were visually verified. For detailed descriptions of all hydrologic unit types, see ftp://ftp-fc.sc.egov.usda.gov/NCGC/products/watershed/hu-standards.pdf.




Data quality report - Absolute external positional accuracy
Dimension horizontal


Measure description
The map was digitized from USGS 1:24,000-scale DRG base maps, with an inherited error of +/- 43 feet according to USGS National Map Accuracy Standards. Digitized line locations were held to the +/- 43-foot accuracy standards by ensuring that all lines were within a 13-meter buffer of where visual interpretation placed the actual boundary. Any lines outside the buffer were corrected. It is estimated that the errors detected were less than 10%. It should be noted that while general rules of hydrology were used (i.e. water flows downhill as opposed to uphill), the location of boundaries is still somewhat subjective as the 1:24,000-scale DRGs do not always provide enough information for identifying the location of the boundaries. In these instances, an additional NED-derived hillshade layer was used and/or group consensus was utilized. Please refer to the 'process description' section for more details on watershed delineation rules. It should be noted that the data was digitzed using NAD27 horizontal datum. The data was then projected to NAD83 horizontal datum as requested by the NRCS. Unquantifiable errors may be associated with coordinate shift.

Process step
Description
Selected watershed polygons that overlap with the study area for the California Freshwater Species Database. Dissolved the polygons based on the huc12 field. Joined the huc12 name back to the dissolved database
Rationale
Some watersheds included mulpile polygons for one huc12 code. We wanted a dataset with 1 multipart feature for each huc 12 code to improve the ease of analysis.

Description
The National Hydrography Dataset is a digital dataset containing surface water features (i.e. lakes, streams, rivers, wells) at 1:24,000-scale, used as a reference layer in conjunction with DRGs to help with stream identification in the editing and attribution processes. In Geodatabase format, the dataset also contains a built-in network for determining flow direction, which is used when creating catchments with ArcHydro tools, as well as assistance during the digitizing process.

Source data
Description
The National Agriculture Imagery Program (NAIP) provides a collection of orthophotography available at 1-meter resolution. This data was used as additional reference in some areas - primarily areas heavily affected by anthropogenic activity and alterations to the natural flow of surface water, as specified in the "Linesource" field of the polyline feature - to improve pour points and watershed/subwatershed boundary locations/delineations. The NAIP images are to be considered the most current and up-to-date reference data available at the time of delineation; because of this, watershed/subwatershed boundaries may not coincide with other source data - such as DRGs - when such data is used as a backdrop layer.

Description
The National Elevation Dataset is a raster representation of elevation at 30-meter resolution. A clipped version of the NED was used to generate a hillshade layer to be used in conjunction with the DRGs to assist in determining watershed/subwatershed boundaries in low elevation areas (i.e. valleys). The NED was also used for terrain analysis (in conjunction with the NHD layer) when generating catchments with Watershed Boundary Dataset Tools (version 1.0).
