The water filtering process in mangrove roots has received considerable attention for several decades 11 12 13. The pneumatophores are often found protruding out of water like stilts when there is low tide. The term is also used for tropical coastal vegetation consisting of such species. As such mangrove roots become home to terrestrial as well as marine plants algae invertebrates and vertebrates. The mangroves give context beauty and function. The metal coating of mangrove roots can inhibit bacterial accessibility to such roots but A mangrove forest depends heavily on a strong network of roots that hold the forest in place against the ebb and flow of the tide. Red mangroves together with the other three U. Mud mangroves usually occur near river mouths thus showing a steep salinity gra dient from marine to fresh water. Some species have knee roots that perform the function. The aerial roots of mangroves partly stabilise this environment and provide a substratum on which many species of plants and animals live. Black mangrove penetrates farthest inland into brackish water and farthest north of the mangrove species. Each perimeter of the mangrove roots is recorded according to the roots numbers for reference in the next data analysis. Mangrove forests grow at the margins of tropical and subtropical coastlines around the world. To elucidate this we investigated the The third type of root is horizontal and fibrous extending into the floor just under the pneumatophores and functions in the absorption of nutrients. 7 Another majorly important function of mangroves near reefs is shoreline protection.
