State agencies (LOSCO, LDNR, OCPR, LDEQ, and LDWF), the RP, private and corporate landowners, and

personnel resources. Access permitting, reporting, and planning was conducted daily throughout project as the

dynamics of the response (oiling conditions, weather, legal, health and safety, technology, etc.) required constant

adjustments to the approach and methodology of the overall NRDA. The scope of the pre-assessment phase

employed up to five independent teams working 7 days a week with management provided at various BP incident

command posts (ICPs) (Houma and New Orleans). Over 1,800 observations were conducted and over 2,500 miles

of Louisiana shoreline were mapped and assessed during the process. Following pre-assessment, also managed the

injury phase in support of the Coastal Vegetation Assessment to evaluate wetland plant community health in four

separate habitats (mainland spartina, back barrier island spartina, delta phragmites, and coastal mangroves). Five

teams have been employed (year 0 and 0.5 events) to setup and/or re-visit approximately 165 monitoring stations

established from the eastern most shoreline of Louisiana (Chandeleur Islands) to the western most impacted

Louisiana shoreline (Point Au Fer Island). The scope of the Coastal Vegetation Assessment was the measurement of

oiling impact, GIS surveying, above and below ground biomass sampling, contaminant sediment sampling, and
