Abstract: 

In 2000, the Sonoma Ecology Center initiated a program to assess the biological and physical/habitat condition of various mainstem and tributary streams within the Sonoma Creek watershed.

Eleven monitoring stations were established and sampled during one, two, or three consecutive years following the standardized protocol, California Stream Bioassessment Procedure (Harrington, 1996), recommended by the California Department of Fish and Game (DFGCalifornia Department of Fish and Game). In April 2006, SECSonoma Ecology Center is a not-for-profit organization located in the Sonoma Valley. http://sonomaecologycenter.org again sampled the eleven original sites, along with three additional sites using an updated DFGCalifornia Department of Fish and Game protocol (Aquatic Bioassessment Laboratory, 2006). Jessie Olson of SECSonoma Ecology Center is a not-for-profit organization located in the Sonoma Valley. http://sonomaecologycenter.org was trained in the physical habitat portion (P-Hab) of the new sampling method by Jim Harrington from DFGCalifornia Department of Fish and Game in June 2006. After receiving training on the new protocol, the P-Hab portion of the assessment was conducted in July through October 2006.

The BMIbenthic macroinvertebrates are streambed organisms often used to monitor the health of a stream. samples collected in 2000 through 2006 were processed by SLSI in Chico, California, and reported back as a stand-alone taxonomic list, and calculated and summarized aquatic macroinvertebrate community based metric values. An overall site score is calculated as the sum of individual metric scores. Sites are then ranked according to their scores and classified into groups with “good,” “fair,” and “poor” water quality. This system of scoring and ranking sites is referred to as an Index of Biotic Integrity (IBI) and is the endpoint of a multi-metric analytical approach recommended by the EPA for development of biocriteria (Davis and Simons, 1995). The original IBI was created for assessment of fish communities (Karr, 1981), but was subsequently adapted for BMIbenthic macroinvertebrates are streambed organisms often used to monitor the health of a stream. communities (Kerans and Karr, 1994). The first demonstration of a California regional IBI was applied to the Russian River watershed in 1999 (Harrington, 1999). The IBI for northern California (Rehn and Ode, 2006) is currently in draft form.
