Abstract
The improved process and apparatus for the restoration of seagrass includes a biodegradable bag or sack, referred to as a sediment tube, that is filled with sand and placed in a prop scar or blow hole. The sediment tube corrects many issues created a prop scar or blowhole: (1) the trench or hole is filled, restoring the elevation of the scar to the surround grade of the seagrass; (2) the sediment tubes stabilize the scar, preventing further erosion of the sand by the flow of water; (3) the sediment tube optionally includes fine-grained sediments that promote seagrass growth and recovery; and (4) the sediment tube includes fertilizer and/or other chemical or minerals that encourage growth.
