SEAGRASS, TREASURE FORGOTTEN

One of the potential marine resource is seagrass. Seagrasses are a group of seed plants (Angiospermae) and single pieces (monocot) that can live under the sea. Seagrass communities are among the lowest limit of the tidal area up to certain depths where sunlight can still reach the sea floor.
Compared with the ecosystem of coral reefs and mangroves, seagrass ecosystems has not been a lot of attention. That is because the beds are not as popular as coral reefs or mangroves that have been clearly known to have economic potential for the human community. Whereas seagrass also has a high economic value, although not directly, but it is a source of capital to produce something very valuable and sustainable.
In fact, this ecosystem is very important presence in the marine ecosystem, because seagrass is a plant that acts as a producer of food for living creatures in the sea. In addition, seagrass can also supply nutrients to coral reefs that once acted as a protective coral reefs of the mud that can damage and kill coral reefs. Even the seagrass beds are also very important role, namely as a place of care, shelter, foraging, shelter or place of migration of various species of animals.
Seagrass ecosystems are very related to the ecosystems in coastal areas such as mangroves, coral reefs, estauria and other ecosystems in supporting the presence of biota, especially in fisheries as well as several other aspects such as physical functioning and socio-economic. This indicates the presence of seagrass ecosystems is not stand alone, but linked to the surrounding ecosystem, greatly influenced even activities ashore. However, the recent shrinking of seagrass condition by the damage caused by natural events and human activities.
Threats from the natural event is usually due to tsunami, volcanic eruptions, cyclones, can cause damage to the coast, as well as to the seagrass beds. Even seagrass damage was also caused by herbivores that consume them in the sea down to its roots. While the damage from human activities include physical damage that causes environmental degradation, such as logging of mangroves, destruction or damage to coral reefs and seagrass habitats, marine pollution, both from land contamination, or from activities at sea; use of fishing gear that is not environmentally friendly; Catch more, by over-exploitation of resources until the recovery of past ability.
Basically, human beings can not control and manage natural activities such as tsunami, earthquakes, cyclones. But we can reduce and menanggulanggi consequences to the management and utilization with environmentally friendly. Even with the policy and good environmental laws, especially in terms of overcoming damage to seagrass due to human activities. For conservation and preservation efforts in order to keep the environment and sustainable use, then developed an integrated approach involving various stakeholders to create the right solutions in maintaining the ecological functions of ecosystems in an integrated coastal management.
