The following species are those that were determined to potentially occur and were targeted for survey effort:

Surveys were conducted along 59 miles of the Stanislaus River, from the confluence with the San Joaquin River upstream to Goodwin Dam. This stretch of the river has 16 parks or accesses areas. The first trip CDFG biologists made was a two day reconnaissance-level canoe trip, May 19 and 20, 1993 which included members of the USBR, USFWS, and DWR. The purpose of this trip was to familiarize the HEP team with the habitat cover types along the river. Although this trip was not organized to survey for birds, all species observed were noted. Additionally, any incidental bird sightings made while conducting amphibian, reptile, or mammal, surveys were also noted. Other sources of information on birds occurring along the Stanislaus River came from Audubon surveys, Corps personnel, and local CDFG biologists. In addition, information from surveys conducted for the following reports was incorporated: Report to the California State Water Resources Control Board on effects of the New Melones Project on fish and wildlife resources of the Stanislaus River and Sacramento-San Joaquin Delta, State Route 120 Oakdale Bypass Report (BioSystems 1994), and the Environmental Assessment for the San Joaquin River National Wildlife Refuge (U.S. Fish and Wildlife Service 1987). All resources were reviewed and compiled into Appendix C.
