Diversity and distribution of macrophytes along the coast of Lebanon (Levantine Basin, Eastern Mediterranean).

It is a small herbaceous plant that occurs in sea beds and other saltwater environments in the Indo-Pacific. The plant occurs around reefs, estuaries, islands, inter-tidal areas, on soft sand or mud substrates. Halophila johnsonii, a species on the U.S. Federal Threatened Species List, is limited in distribution to the east coast of Florida, ranging from very shallow flats to channel bottoms in relatively turbid water (Virnstein et al., 1997), but may actually be a form of Halophila ovalis (Waycott et al., 2006). Wetland Status. This paper describes the biomass, distribution and primary production of this plant in relation to environmental factors.Halophila ovalis occupied 550-600 ha in the lower reaches of the estuary, approximately 20% of the area of the main estuarine basin. The main growing period was summer, when marine salinities prevailed, and light supply and temperature were highest. The seagrass genus Halophila Thouars has more than twenty described species and is predominately distributed over a wide geographic range along the tropical and the warm temperate coastlines in the Indo-West Pacific Oceans. In the study area, H. ovalis was found in the tidal flat of the intertidal zone and the clay-like and arenaceous parts of subtidal zones (Shi et al.
