... S ea turtles play numerous roles in marine ecosystems from mainland beaches to oceanic waters; for example their shells RESTORATION OBJECTIVES serve as mobile habitat or resting space for hundreds of species of invertebrates, fish, and The overarching goal of sea turtle restoration birds, and they transport nutrients across in the Gulf of Mexico following the Deepwater ecosystems including from sea to land. As part of Horizon oil spill is to implement an integrated marine food chains, sea turtles affect many plants, portfolio of restoration approaches to address all animals, and habitat directly and indirectly injured life stages (hatchling, juvenile, and adult)

Example #1 (linkages shown in the table by "#1") is to construct corrals on sea turtle nesting beaches; Example #2 is to reduce artificial lights on sea turtle nesting beaches; Example #3 is to control predators on sea turtle nesting beaches; Example #4 is to restore stranded turtles; and Example #5 is to reduce fisheries bycatch.
