Mangrove Trees: The Tree of Land and Sea

“Oh! those mangroves. I never saw one that looked as if it possessed a decent conscience. Growing always in shallow stagnant water, filthy black mud, or rank grass, gnarled twisted, stunted and half bare of foliage, they seem like a crowds of withered, trodden-down old criminals, condemned to the punishment of everlasting life. I can’t help it if this seems fanciful. Anyone who has seen a mangrove swamp will know what I mean”(Davidson, 1998). The mangroves are unique species. A tree that is able to live in saltwater. On the coast of Florida, the mangroves are most plentiful. Striving in areas were the freshwater from the main land and the seawater meet. The different variances of salinity gradient in the water create three different optimal zones for the different species, red, white and black (Cummins, 2007). The three species live very close together, and it is common to find the unique roots, which will be discussed later, intertwine with one another. These trees do not only intertwine by themselves though, “you almost always find coral, mangroves and sea grasses together” (Davidson, 1998). The mangroves are an important part of the intertidal zone and the marine ecosystem.
