Topic	Aquatic Invertebrates: Walker Creek Percent Dominant Taxa 2001

Caption: The Chart Table invert_cdfg_walker_2001.db is the same as the associated Source Table, although filtered for WATERSHED = Walker Creek. This table contains data from aquatic invertebrate sampling in the Walker Creek watershed during spring 2001 by the San Francisco Bay Regional Water Quality Control Board. The abbreviations in the column headings are TAXARICH = Taxonomic Richness, CUMTAXA = Cumulative Taxa, PCTDOMTAXA = Percent Dominant Taxa, EPTTAXA = EPT Taxa, EPTINDEX = EPT Index (%), SENEPTINDEX = Sensitive EPT Index (%), CUMEPTTAXA = Cumulative EPT Taxa, CHIRONPCT = Chironomidae (%), SHANNON = Shannon Diversity, TOLVALUE = Tolerance Value, INTOLTAXA = Intolerant Taxa (%, 0-2), TOLTAXA = Tolerant Taxa (%, 8-10), COLLECTORS = Collectors (%), FILTERERS = Filterers (%), GRAZERS = Grazers (%), PREDATORS = Predators (%), SHREDDERS = Shredders (%), ABUNDANCE = abundance ((#/m^2), AREASAMPLED = Area sampled (feet^2), AVG = average, and SD = standard deviation.

50 rows of a possible 4247 have been displayed.
