6 DWH Data Flow Resource Groups Formed Workplans Created Data Collected Data Verified Data Analyzed Data Interpreted

7 Louisiana Workplan Overview 24 Habitat Pre-assessment Workplans 6 finalized 18 under review Approximately 17,000 habitat data records collected to date 50 Aquatic Pre-assessment Workplans 16 finalized 34 under review Approximately 1,800 aquatic data records collected to date 16 Wildlife Pre-assessment Workplans 9 finalized 7 under review

8 Pre-Assessment Workplans: Habitat Example Deepwater Horizon/MC252/BP Shoreline/Vegetation NRDA Pre-Assessment Plan Purpose: Determine shoreline areas exposed to oil Characterize exposed shorelines (habitat, vegetation and fauna) Identify monitoring stations for injury assessment Data Collection: Delineate spatial extent and degree of oiling Describe observed impacts to vegetation and biota Oil sample collection

9 Pre-Assessment Workplans: Wildlife Example Work Plan for Estimating Secretive Marsh Bird Mortality Deepwater Horizon (MSC 252) Oil Spill NRDA Bird Study #3 Purpose: Quantify abundance & density of secretive marsh bird species in unoiled representative habitats Quantify proportion of live oiled & live un-oiled birds in representative habitats through active capture of live individual birds Estimate representative marsh bird mortality rates using radio telemetry Quantify fiddler crab burrow densities to supplement our understanding of marsh-specific rail densities Data Collection: Point counts & playback surveys Fiddler crab densities Radio Telemetry of adult rails and seaside sparrows

10 Pre-Assessment Workplans: Oysters Pre-assessment Oyster Sampling Plans: Phase 1 Plan & Transition Plan Purpose: Determine exposure from oil and response activities Estimate mortality rates Examine long-term impacts on reproductive ability Data Collection: Oyster density (population) Larval supply Contaminant data in tissue samples and sediments

11 Data Collection Points 1/25/10

12 Programmatic Environmental Impact Statement Purpose: To identify types of restoration that could be used to compensate the public for lost resources and their services, as well as a framework and procedures for the selection and implementation of restoration projects that will compensate the public for natural resource damages caused by the Oil Spill.
