  1. BENTHIC MACROINVERTEBRATE AND PERIPHYTON MONITORING IN THE SUWANNEE RIVER BASIN IN FLORIDA 1: OVERVIEW AND BIOGEOGRAPHY

  2. Periphytic Algae • Micro- to macroscopic algae growing on hard surfaces • Major source of autochthonous (“in-stream”) primary production • Respond to natural and human-created changes in water quality • Integrate environmental effects over time

  3. Benthic Macroinvertebrates • Invertebrates retained by 0.5 mm mesh sieve • Ecologically important group of animals in all aquatic ecosystems in the drainage • Also respond to natural and human-created changes in water quality and habitat • Integrate environmental effects over time

  4. Suwannee Basin Florida animal biodiversity

  5. Suwannee River DrainageBenthic Community Sampling in Florida • Fla. Fish & Wildl. Conservation Commission(resource assessments) • Fla. Dept. of Environmental Protection(monitoring, impact assessment, stream bioassessment program) • Suwannee River WMD(SWIM monitoring, basin assessments) • USGS Biol. Resources Division(sturgeon & seatrout food resources) • USEPA(NPDES impact studies) • Private consultants(point source impact studies, NPDES monitoring) • Citizen groups

  6. Suwannee River Water Management District Benthic Monitoring Program • began in 1989; currently continuing • quarterly sampling • multiple gear types: • Hester-Dendy, Periph. & dip net (streams) • Petite ponar (streams and lakes) • mainly streams (some lake studies) • same organization doing sampling • same taxonomists

  7. Hester-Dendy sampler D-frame dip net Periphytometer BENTHIC SAMPLING GEAR Used in SRWMD Program Petite ponar grab

  8. Suwannee River Water Management District Benthic Monitoring Program • Sampling design (sites and methods): • SRWMD • FDEP • FWCC • USGS • Field sampling: Environmental Services and Permitting, Alachua, FL • Taxonomy: Dr. John Epler (invertebrates) Mr. Michael Hein (algae)

  9. SUW010 SUW100 SUW130 SUW150 SRWMD • Water quality sites • Wq / biology sites • Inactive biology sites SUW240
