Steelhead Critical Habitat, Central Valley - NOAA [ds123]
Dataset Identification:
Resource Abstract:
This layer depicts areas designated for Steelhead Critical Habitat as well as habitat type and quality in the California Central
Valley Evolutionary Significant Unit (ESU - a "distinct population" of Pacific salmon defined as a "species" under the Endangered
Species Act). These data represent the stream segments identified as Critical Habitat by the National Marine Fisheries Service
(NOAA Fisheries) Southwest Regional Office (SWR). The linework for this layer is based on the California Department of Fish
and Game (CDFG) and Pacific States Marine Fisheries Commission (PSMFC) 1:100,000 scale stream based routed hydrography. SWR
biologists divided the routed hydrography into stream segments using the best available information to represent local Steelhead
distribution and habitat. As a result, each segment has its own unique identifier (GIS_Link) and related presence and habitat
information. The data set is in shapefile format and can be included as a map layer in a GIS. This data set This GIS layer
is part of a larger mapping effort to define the anadromous distribution and to designate critical habitat in five steelhead
ESU's and two Chinook ESU's in California. Several NOAA Fisheries offices participated in this effort. As a result, although
the same issues were addressed within each ESU, the offices chose differing approaches to define and populate the habitat
attributes. The consequence is that there are some slight differences in the attribute tables between the coastal ESUs and
the Central Valley ESUs. For a complete description of the NOAA Fisheries Critical Habitat Designation project and for links

This layer was created to depict Critical Habitat for Steelhead in the California Central Valley ESU. The layer represents
areas designated for Critical Habitat and the habitat quality in the region. It is best suited for mapping those properties
in the aforementioned region. For a complete description of the NOAA Fisheries Critical Habitat Designation project and for
