| Topic | Aquatic Invertebrates: Drakes Bay Tributaries RRIBI Scores 1999 |
Caption: The Chart Table invert_pore_sum_1999_drakes.db shows mean metrics with associated Russian River Index of Biological Integrity (RRIBI) scores, as well as total RRIBI, for benthic macroinvertebrates collected at several locations in Drakes Bay tributaries. Data were collected by the Point Reyes National Seashore during fall 1999 and the insects were identified by Jon Lee Consulting. The abbreviations in the columns are TAXARICH = Taxa Richness, EPTTAXA = EPT Taxa, MODEPTINDEX = Modified EPT Index, PCTDOM = Percent Dominant Taxa, SHANNON = Shannon's Diversity Index. See Info Links for more information. Note that descriptive locations for Home Ranch Creek were not available when data were integrated into KRIS.
50 rows of a possible 373 have been displayed.
