Seagrass is the grasses found in seabed around the world. They are important for the aquatic ecosystem as they provide shelter to the organism thriving in the earth. Due to various anthropogenic activities, Seagrass meadows have become the most endangered ecosystem in the earth.
It is claimed that when the flowering terrestrial plant moves towards the ocean more than ten thousand millions years ago and the seagrass was created.
Due to this Seagrass resemble the terrestrial grasses. Pollination is often carried out by the process often refers to as submarine pollination.
The Advantage of Seagrass:
1. Due to their ability to photosynthesize, they generate the oxygen gas inside the ocean that is helpful to detoxify the substratum Hydrogen sulfide. This is the vital part for the sustenance of aquatic ecosystem. Further, oxygen has the innate capacity to destroy the several pathogens.
2. Seagrass provides the nursery for the development of fish that is vital for the different species of fishes including some commercial varieties.
3. Seagrass is claimed to control the pathogens spread thus facilitating adequate condition for the growth of aquatic ecosystem, human, etc.
4. It is believed to detoxify pollutant in water from the nonpoint source like fertilizer runoff from the field.
5. They are good carbon sink as they store the significant amount of carbon. It accounts for more than ten percent of ocean carbon storage.
6. They are often referred to as ecosystem engineer due to their ability to slowing down the water current, increasing the process of sedimentation, stabilizing seabed.
Concern on Seagrass
The major concern is the rapid disappearing of this meadow mainly due to anthropogenic activities. It is roughly estimated that one-third of the seagrass has been disappearing from the earth.
The coral reef is infected with bacteria and fungi due to Seagrass disappearance.
Major Causes of Disappearance
1. Due to turbid water Seagrass cannot utilize the light required for photosynthesis. Without photosynthesis, Seagrass cannot thrive.
2. Due to Warmer Ocean oxygen is rapidly escaping from the leaf of the Seagrass. The toxic sediment substratum is being poisonous as less oxygen is available to pump through the root.
3. Human motorboat blade sometimes chops up the Seagrass. Massive use of the motorboat is accelerating the process.
Restoration of Seagrass
Restoring is the process of placing in the original position. Integrated restoration practice is required for restoration. Some of the restoration practice can be:
1. Applying series of feasible strategies to prevent nutrient runoff from the soil. This is effective for the recovery of the Seagrass.
2. Replantation of the Seagrass needs to be done in the place where the Seagrass has vanished.
3. Blade in the human motorboat needs to be modified to make less destructive to the Seagrass.
