Mangrove conservation in coastal areas Samas beach lagoon for controlling sea water abrasion

Lagoon is a puddle of water (like a lake/pond) near the beach that was once a part of the (united with) the sea, but because of geological events, apart from the sea and coastal wetland ecosystems forming new ones. Samas beach lagoon is one of the lagoons are located in Bantul, Daerah Istimewa Yogyakarta. From the perspective of the Environment, lagoon is a unique ecosystem that consists of a body of water (lagoon) is brackish, mangrove forests and land affected low tide. Ecosystem functions as shrimp and fish spawning, habitat for birds and other creatures. From the perspective of Water Resources, lagoon is included in the watershed that is downstream of the basin Opak. The high rate of siltation due to sedimentation Opak and poor drainage and are affected by erosion and seawater intrusion impact on environmental degradation around the samas beach lagoon. In ecology water to reduce flooding in the surrounding plains at high tides or when rain water catchment at the same time cause a reduction in the amount of water that flooded the estuary downstream. The edges of the lagoon had thus potentially erosion and accelerating siltation lagoons and muddy lagoon water and cause environmental damage. Mangrove forests as one of the potential natural resources have long sought. The conduct of mangrove conservation in coastal area of samas beach lagoon serves the split waves and erosion control so that the coastal area of samas beach lagoon is able to maintain the balance of coastal aquatic ecosystems, protect the coast and river banks from erosion or erosion, intrusion resist and precipitate sludge and filter material contaminated.
