Mangroves are hardy shrubs and trees that thrive in salt water and have specialised adaptations so they can survive the volatile energies of intertidal zones along marine coasts. A mangrove is a shrub or tree that grows mainly in coastal saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal ...
Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. [1] [2] Mangrove forests grow mainly at tropical and subtropical latitudes because mangrove trees cannot withstand freezing temperatures. There are about 80 different species of mangroves, all of which ...
Mangroves are often found near or around salt ponds because of their ability to exist in an ecosystem with high salinity, low dissolved oxygen levels, brackish water, and extreme temperatures. Mangroves’ unique prop roots function as a barrier to the salt water, limiting water loss, and acting as a snorkel for oxygen and nutrients.
Grey mangroves grow as a shrub or tree to a height of 3 to 10 m (10 to 33 ft), or up to 14 metres (46 ft) in tropical regions. The habit is a gnarled arrangement of multiple branches. It has smooth light-grey bark made up of thin, stiff, brittle flakes. This may be whitish, a characteristic described in the common name.
The bark is gray on the outside with a red interior. These trees also have small white flowers that are wind pollinated with 10-12 inch long pencil shaped seeds.

The Sunda Shelf mangroves ecoregion, in the mangrove biome, are on the coasts of the islands of Borneo and eastern Sumatra in Malaysia and Indonesia. They are home to the proboscis monkey . As well as being an important habitat for terrestrial and marine wildlife, mangroves preserve the shape of the coastline.
Mangrove trees grow on a narrow strip between land and ocean in river systems, between the latitudes 25 degrees N and 30 degrees S, and the constant renewal of the trees relies on rivers bringing nutrients to the coast in regular seasonal patterns. The limited distribution of this ecosystem adds to the delicacy of it.
Rhizophora mangle - MHNT. Rhizophora mangle, also known as the red mangrove, [1] is a salt-tolerant, small-to-medium sized evergreen tree restricted to coastal, estuarine ecosystems along the southern portions of North America, the Caribbean as well as Central America and tropical West Africa. [2]
