These seagrass meadows are highly productive habitats that provide many ecosystem services, including protecting the coast from storms and big waves, stabilising sediment, providing safe habitats for other species and encouraging biodiversity, enhancing water quality, and sequestering carbon and nutrients. [12] [3]
Seagrasses form dense underwater seagrass meadows which are among the most productive ecosystems in the world. They function as important carbon sinks [3] and provide habitats and food for a diversity of marine life comparable to that of coral reefs.
Found on seabeds from Alaska to Australia, seagrass meadows are one of the most widespread coastal habitats on Earth. ... “It’s important to think about restoration as an ongoing process; it ...
Blue carbon is defined by the IPCC as "Biologically driven carbon fluxes and storage in marine systems that are amenable to management." [2]: 2220 Another definition states: "Blue carbon refers to organic carbon that is captured and stored by the oceans and coastal ecosystems, particularly by vegetated coastal ecosystems: seagrass meadows, tidal marshes, and mangrove forests."
Seagrass meadows provide homes for young fish and protected creatures such as seahorses and stalked jellyfish.
However, today seagrass meadows are being damaged by human activities such as pollution from land runoff, fishing boats that drag dredges or trawls across the meadows uprooting the grass, and overfishing which unbalances the ecosystem. Seagrass meadows are currently being destroyed at a rate of about two football fields every hour.
The die-offs persist, raising the question — can 21st century Florida and seagrass coexist? In the timescale of ecosystems, the collapse of Florida’s seagrass has been sudden, severe and ...
Shark Bay has the largest known area of seagrass, with seagrass meadows covering over 4,000 square kilometres (1,500 sq mi) of the bay. [1] It includes the 1,030-square-kilometre (400 sq mi) Wooramel Seagrass Bank , the largest seagrass bank in the world [ 1 ] and contains a 200-square-kilometre (77 sq mi) Posidonia australis meadow formed by a ...
