Saltmarsh

That grass – saltmarsh cordgrass, which can grow to be 7 feet tall – was being observed in New Smyrna Beach, Florida as part of a Fish and Wildlife Service program.

There has been some investigation into the potential of seaweeds as a carbon store, and although more is needed, one study says that seaweed habitats are believed to be the most productive of all coastal vegetated ecosystems, and suggested that the world’s seaweed sequesters as much carbon as all the planet’s seagrass meadows, saltmarshes and mangroves combined.
