Transcript of Structural and Dynamic Habitat in the Suwannee Estuary

  • Structural and Dynamic Habitat in the Suwannee EstuaryEllen Raabe, Randy Edwards, and Carole McIvor

  • Cooperative EffortCooperative data acquisition with FDEPFWS/USGS cooperativeUSGS Directors Venture CapitalIntegrated science

  • Why Suwannee Estuary?Confluence of fresh and tidal waters (MFL)Existing Research/FWSUnique Setting and Ecological valueRecreation and Shellfish IndustryOpportunity for Integrated ScienceCASI imagery Suwannee Estuary Bands 9,7,5

  • An application of remotely sensed imagery to integrated habitat mappingTo map subtidal and intertidal habitat with hyperspectral imagery (CASI)To link structural and dynamic habitatTo link habitat to fish ecologyTo develop resource management tool

  • Tidal creek in forestFlooded low marshSubmerged limestone and high brackish marshSubmerged flatsHABITAT

  • Habitat MapCASI imagery4m, 12 bandsHabitatsSubmergedEmergentUplandsBumblebee CreekBarnett Creek

  • Estuarine Fish EcologySimilar species composition North and SouthFreshwater species in south tidal creeksSeasonal and interannual variation?Habitat use and preferences?Dynamic habitat and benthic biota?

  • Dynamic Habitat0-25 pptTidal lag into creeks1.5 - 2 hoursNet GW dischargeAt low tideStrongest signal in northern creekNeed data:Water flow/depthWQ and salinitySediment loadPlanktonBenthic biotaAccessibility, duration, stability

  • Flood zonesSubmergedTidal creeksShallow flatsLow marshBrackish marshHigh marshLow elevation freshwater habitats

  • FutureStrengths of remotely sensed imageryLow impact to habitatObjective and large geographic coverageVaried resolution and band selectionTopography, thermal, hyperspectralRepeatabilityquantitative change versus qualitativehabitat dynamics versus snapshotBenthic Habitats: expand new field, new techniqueto basin river bed, wetlands, uplandsto water source, quality and levels

  • Landscape Level LinksBathymetry and topography - mergeTidal and sea level dynamicsRiver discharge, groundwater and estuarine water qualityGeology and sedimentary processfrom Ecosystem to MicrohabitatWetland biota with habitatEstuarine health and productivity

  • SummaryDetailed habitat and substrate featuresManagement tool (FWS)Road impactSpecies habitatTide levels and floodCoordinate with hydrology, biota, & geomorphic process studiesNeed:comprehensive mapping efforthydrologic monitoring and models (GW)spectral signatures of select featuresidentification of key issues
