The selection of special-status species for detailed treatment in this EIR/EIS was based on the extensive comments received during the scoping process. Those comments led to initial consideration of a list including all special-status animal species known to occur in California. Through 2008, during public scoping meetings and subject to input from USFWS and DFG staff familiar with the history and operation of hatchery and stocking programs or the biology of special-status species, various species on the initial list were determined to either require evaluation or not require evaluation in this EIR/EIS. Generally, a species was regarded as requiring evaluation if it was:
- known to occur in riparian, wetland, or aquatic habitat adjoining or within a few miles downstream of a fish hatchery evaluated in the EIR/EIS;
- known to occur in riparian, wetland, or aquatic habitat at sites where fish stocking is performed under one or more of the stocking programs described in this EIR/EIS; or
- known to be vulnerable to ecosystem-level impacts such as alteration of food webs by stocked fish, alteration of riparian and aquatic systems by the activities of anglers, or various other indirect mechanisms that have been reported in published studies of fisheries and aquatic ecosystems.
Similarly, if a species did not meet any of these criteria, it was removed from consideration for detailed evaluation within this EIR/EIS.

Several species that are not special‐status species were added to the review list because of DFG concerns that they might be affected by stocking programs. Since the final list of species addressed in this chapter includes some species that have no special‐status designation, they are cumulatively referred to as “decision species.”
