Project

Characterizing Intertidal Assemblages

AMS scientists designed and implemented a program to assess intertidal assemblages and evaluate concentrations of petroleum hydrocarbons at the Point Reyes National Seashore for the National Park Service (NPS). The objective of the program was to describe baseline conditions for Natural Resource Damage Assessment (NRDA) actions that may be necessary in the event of a future oil spill. Rocky intertidal areas, eelgrass beds, and tidal flats of the park were assessed for the percentage cover of plants and animals. Sediments and select bivalve species were tested for concentrations of petroleum hydrocarbons. A key component of the project was the development of a monitoring handbook which provides NPS staff the information needed to continue the monitoring activities.
