... Seagrass meadows expand and enhance seagrass meadows in many provide valuable ecosystem services such as locations. The general objective of these efforts is important habitats and food for a range of iconic to facilitate the development of seagrass meadows species such as manatees, green turtles, and whose areal extent, abundance, species seahorses; providing nursery grounds for composition, function, and provision of numerous economically important finfish and ecosystem services are assessed to be equivalent shellfish; sequestering carbon; improving water to those of reference meadows (see Chapter 3)
