How do you restore a broken seagrass mattress? Get birds to return to the occasion! Biologists in Florida Keys Nationwide Marine Sanctuary place T-shaped PVC stakes in seagrass beds which were scarred by boat propellers. These stakes function perches to draw terns, gulls, and different birds, which produce guano droppings which are wealthy in vitamins — which in flip assist velocity regrowth of seagrass within the barren space!
In Florida’s shallow waters, the seagrass meadows that host plentiful wildlife are broken when boat propellers cross by means of them. Propellers go away a everlasting scar that can’t regrow by itself. (See scars in two embedded images under).
When the seagrass declines, so do fish and wildlife. This drawback is so vital to Florida that the state imposes fines on boaters who injury it and has tasked the Workplace of Resilience and Coastal Protections (RCP) to revive the seagrass beds.
RCP takes a two-pronged strategy to restoration. Step one is to boost consciousness amongst boaters and put up indicators in order that they avoid the seagrass beds.
The second step is to revive the propeller scars so the grass can regrow inside the cuts. At St. Martins Marsh Aquatic Protect:
RCP has partnered with the UF/IFAS Nature Coast Organic Station to stabilize and restore prop scars with sediment tubes. Sediment tubes accomplish this by returning the scarred areas to ambient elevations, stopping extra erosion and scouring by water currents, and defending rhizomes from extreme daylight publicity. The approach includes putting in biodegradable cloth tubes full of sediment into scarred areas that biodegrade in about 12 months.
Seagrass beds may be fertilized passively to encourage regrowth by means of the location of chicken roosting stakes and has been proven to be fairly profitable, as may be seen in Large Lagoon in Pensacola in Fort Pickens Aquatic Protect.
Add soil, then add guano.

In 2009, the Florida Legislature created a rule to additional defend seagrass by imposing fines to boaters who injury seagrass with their boat propellers (Part 253.04(3)(a), Florida Statutes). …
RCP [The Office of Resilience and Coastal Protection] has employed a wide range of seagrass restoration strategies all through the state. These tasks have been performed in Charlotte Harbor, Indian River Lagoon, Biscayne Bay, the Large Bend, the Florida Keys, St. Joseph Bay, St. Andrews Bay and Pensacola Bay. Outcomes have been combined, and RCP is continuous to watch these tasks and work with different researchers to seek out simpler methods to revegetate the underside.
