| Topic | Aquatic Invertebrates: Olema Creek RRIBI Scores 1999 |
| Caption: The results displayed show the mean total RRIBI (Russian River Index of Biological Integrity) score at several locations in Olema Creek during fall 1999. The reference value shown in the graph provides a regional comparison to preliminary scores developed by the California Department of Fish and Game for the Russian River Index of Biological Integrity using California Stream Bioassessment Procedure (CSBP) for first to third order streams (Harrington et al., 1999). This study found that IBI scores between 6 and 11 reflected poor biotic conditions (6 is the minimum score possible). The Point Reyes National Seashore collected these aquatic invertebrates according to the CSBP protocols and they were identified by aquatic entomologist John Lee.
