Crews that conducted the inventory were trained in standardized habitat inventory methods and supervised by CDFG. The methodology utilized in the Russian River basin follows the procedures in the California Salmonid Stream Habitat Restoration Manual (Flosi et al. 1998). Following completion of a desktop watershed information assessment, CDFG conducted in-field fish habitat inventories including: 1) stream channel typing; 2) habitat typing; and 3) biological surveys to describe fish habitat utilization and distribution of fish and other aquatic species basin-wide .
CDFG has established “benchmarks” to define target
habitat objectives established for north coast salmonid bearing
streams. These benchmarks were adapted from the California Salmonid
Stream Habitat Restoration Manual (Flosi, et al. 1998), and the
Oregon Watershed Assessment Manual (OWEB, date) by Robert Coey,
Associate Fish Biologist, CDFG, May 2000. Recommendations were developed
from a limiting factors analysis which determined the condition
of each stream, relative to how close each variable met the benchmark
criteria (CDFG 2002).

constraints on use.
