This dataset was created using the 123 PISCES extant species range layers listed below in the table. The PISCES datasets were converted to rasters using GIS and then map algebra was used to calculate the total number of species in each huc12 watershed. Using GIS, an extended table was created to provide species lists by watershed using a one to many table relate. Species presence data was provided by PISCES: Moyle, Quinones and Bell (direct addition), Moyle and Randall (gstpoly), . These layers were generated by PISCES on 10/30/2014. The datasets listed in the table below were used in this analysis.Pisces_CodeCommon_NameAAM01Northern Green SturgeonAAT01White sturgeonCCF01Owens SuckerCCO02Goose Lake SuckerCCS01Klamath Largescale SuckerCCA03Clear Lake Prickly SculpinCCG01Riffle SculpinCCK03Upper Klamath Marbled SculpinCCK01Bigeye Marbled SculpinCCK02Lower Klamath Marbled SculpinCCN02Amargosa River PupfishCCN01Saratoga Springs PupfishCCN04Shoshone PupfishCCS03Salt Creek PupfishPEF01Northern California Brook LampreyPES01Klamath River LampreyPET02Goose Lake LampreyPET01Pacific LampreyCGC01Blue ChubCGO01Arroyo ChubEHT03Clear Lake Tule PerchEHT02Russian River Tule PerchEHT01Sacramento Tule PerchPLH01Kern Brook LampreyPLL01Pit-Klamath Brook LampreyPLR01Western Brook LampreyCLE01Sacramento HitchCLE03Monterey HitchCLP01Gualala RoachCLS06Navarro RoachCLS05Monterey RoachCLS04Clear Lake RoachCLS02Red Hills RoachCLS03Russian River RoachCLS07Tomales RoachCLS01Central California RoachCMC01HardHeadSOC01Coastal Cutthroat TroutSOM03Klamath Mountains Province Winter SteelheadSOM04Klamath Mountains Province Summer SteelheadSOM14California Golden TroutSOM12Eagle Lake Rainbow TroutSOM13Kern River Rainbow TroutSOM10McCloud River Redband TroutSOM11Goose Lake Redband TroutSOT08Central Valley Fall Chinook SalmonSOT07Central Valley Late Fall Chinook SalmonSOT03Southern Oregon Northern California Coast Fall Chinook SalmonSOT01Upper Klamath-Trinity Fall Chinook SalmonSOT02Upper Klamath-Trinity Spring Chinook SalmonCCP01Lahontan Mountain SuckerCPM01Sacramento SplittailSPW01Mountain WhitefishCRO06Amargosa Canyon Speckled DaceCRO05Long Valley Speckled DaceCRO04Owens Speckled DaceCRO07Santa Ana Speckled DaceCSB03Lahontan Lake Tui ChubCSB05Eagle Lake Tui ChubCST01Goose Lake Tui ChubCST03Cow Head Tui ChubAAM02Southern Green SturgeonCCL01Lost River SuckerCCM01Modoc SuckerCCO04Humboldt SuckerCCO03Monterey SuckerCCO01Sacramento SuckerCCR01Klamath Smallscale SuckerCCS02Santa Ana SuckerCCT01Tahoe SuckerCCB01Shortnose SuckerCCA04Coastrange SculpinCCA02Prickly SculpinCCA01Rough SculpinCCB02Paiute SculpinCCP03Reticulate SculpinCCP02Pit SculpinCCM02Desert PupfishCCR02Owens PupfishCCS04Cottonball Marsh PupfishGEN01Tidewater GobyCFP01California KillfishGGA01Coastal Threespine SticklebackGGA02Inland Threespine SticklebackGGA04Santa Ana (Shay Creek) SticklebackGGA03Unarmored Threespine SticklebackOHP01Delta SmeltPLA01River LampreyCLE02Clear Lake HitchCLS08Northern (Pit) RoachCLA01Staghorn SculpinMMC02Striped MulletSOC03Lahontan Cutthroat TroutSOC02Paiute Cutthroat TroutSOG01Pink SalmonSOK03Chum SalmonSOK01Central Coast Coho SalmonSOK02Southern Oregon Northern California Coast Coho SalmonSOM05Central California Coast Winter SteelheadSOM06Central Valley SteelheadSOM02Northern California Coast Summer SteelheadSOM01Northern California Coast Winter SteelheadSOM07South Central California Coast SteelheadSOM08Southern California SteelheadSOM09Coastal Rainbow TroutSOM15Little Kern Golden TroutSOT04California Coast Fall Chinook SalmonSOT06Central Valley Spring Chinook SalmonSOT05Central Valley Winter Chinook SalmonCOM01Sacramento BlackfishPPS01Starry FlounderCPG01Sacramento PikeminnowCRO03Klamath Speckled DaceCRO02Lahontan Speckled DaceCRO01Sacramento Speckled DaceCRE01Lahontan RedsideCSB01Klamath Tui ChubCSB04Lahontan Stream Tui ChubCSB06Owens Tui ChubCST02Pit River Tui ChubOST01Longfin SmeltOTP01EulachonCXT01Razorback Sucker
