Mangroves are one of the most productive and biologically complex ecosystems on earth. They develop plain and muddy grounds which can be easily and constantly flooding during high tide. The mangrove species can occupy unstable grounds due to their morphological adaptations, which dominate the ecosystem and they can grow with salinization between 0-40 ppm. We can find them in the river mouths, firths, or coastal areas.

Mangrove forests are of great importance for the stability of the coast because they reduce erosion, protect against high winds and high tides. Within their roots fish and diverse organisms search for food and refuge from predators. They serve as source of food and shelter. Amongst the organisms living in this ecosystem we find a wide variety of birds, crustaceous, mollusks and even bacteria and fungus which are essential for the decomposition of organic matter.

One of the most important functions of this ecosystem is the desalination of the ground through the exchange of water, and its function as a filter. Fishery also depends highly on this ecosystem because it acts as a cradle of diverse marine organisms.
