Abstract:
We delineated Key Riparian Corridors and Riparian Buffer Zones to identify important rivers and streams that complement the Linkage Network. For more information about the creation of the data, please see the report at http://www.scwildlands.org/reports/Default.asp

Purpose:
Selected streams and rivers in the Key Riparian Corridors dataset were buffered by 1 km on either side (when occurring outside of Large Landscape Blocks, Linkage Designs, or Important Baylands) and added to the Linkage Network as they provide key resources and habitat connectivity for multiple aquatic and terrestrial species.

Data Quality Information:


Completeness report:
This data set is in final form.  Occupancy and habitat designations are based on a 1:100,000 hydrography data layer.  Therefore, any streams not visible at that scale were not included in the designation process.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
The positional accuracy of each designated stream segment varies with the amount of information available for that particular stream reach, as well as the precision with which the stream segment's upper and lower extents were marked on the paper maps, and how accurately that information was transferred into a digital format.  The positional accuracy is also dependent on the basemap data used in the process.  The stream segment determinations can be no more accurate than the CDFG 1:100,000 hydrography layer they are based on.  As a result, this data set is not suitable for any type of high-precision measurement applications.

Lineage:
Process step:
Process description:
Stream segments were identified and assigned attributes by SWR biologists using CDFG 1:100,000 hydrogrography data and other basemap information on hard copy maps.  The segments' upper and lower extents were manually marked onto the basemaps by the biologists.  This information was then visually interpreted from the paper maps and entered into a digital format using the "Route Tools" extension provided by CDFG.  The resulting event table was then used with the CDFG routed hydrography as the route reference to create routed events based on the biologists' segment determinations.  The table containing the accompanying segment attribute information was joined using 'GIS_Link' as the related field, and the shapefile 'CCC_Steelhead_Draft_2004' was created from the routed events.  To minimize errors that may have occurred during the process, the completed digital file was compared against the marked maps for consistency.  The biologists also reviewed the completed digital file to ensure attribute information was associated with the correct stream segments.

Biologists rated each Calwater (California Watershed Map) Hydrologic Sub-area (HSA) based on occupancy and habitat quanitity and quality information found in the Steelhead distribution shapefile (CCC_Steelhead_Draft_2004).  These biological ratings were compared against economic values given to each HSA.  Based on whether selected criteria were met, an HSA was determined to be included or excluded from Critical Habitat.  All stream segments were then coded to reflect their HSA's designation.  The only exceptions to this occured when a stream segment was valued as a migration corridor (the segment would be included as Critical Habitat even if the HSA was excluded) or if there were other overriding biological considerations.

Those segments coded as Critical Habitat were then extracted from the distribution shapfile and placed in the resulting 'CCC_Steelhead_Proposed_Critical_habitat' file.  Public comments were received following draft publication of the Critical Habitat Proposed Rule in December 2004.  These comments were incorporated into the data set and the final critical habitat file 'CCC_Steelhead_CH_06_2005' was created.
