was to identify any special status species that would require more specific studies. Literature
that was pertinent to the study area was also reviewed before bird surveys began. 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.
