These trees may not look like anything special, but they have unique adaptations that allow them to live in saltwater environments, and provide crucial habitat for many marine species. According to a recent report, every 330 feet of mangrove forest can reduce wave height by up to 66%. They are represented on all continents with tropical and subtropical coasts, i.e. At present, mangroves enjoy limited protection, with some 1,500 acres in the central mangrove wetland under protection. Mangroves are the only trees that are capable of thriving in salt water. JIRCAS Library benevolent guardians of human civilization, Plants Much Less Affected By Mass Extinctions Than Animals, Research Finds. Climate and sea level have drastically altered mangrove distribution since their appearance in the geological record ∼75 million years ago (Mya), through to the Holocene. Mangroves’ strong roots help prevent erosion by trapping sediment in their tangled roots. Other animals live directly on the roots, including snails, barnacles and oysters. Although some species of extant angel sharks occur in estuaries and may be relatively common in the vicinity of estuarine fronts (Vögler et al., 2008), there are no records of them being present in abundance in close proximity to mangroves (see Compagno, 1984).
