Part of a mangrove forests value comes from its ability to modify and support the surrounding environment. As the bats fly in for a drink, the pollen from the flower sticks to their bodies. With their roots submerged in water, mangrove trees thrive in hot, muddy, salty conditions that would quickly kill most plants. In most cases, they approach mangrove restoration as if they were planting a forest on land. Every ecosystem is made up of three broad components: producers, consumers and decomposers. >> While most terrestrial plants use whats called a taproot to burrow deep into the ground for support, several mangrove species rely on sprawling cable roots that stay within a few centimeters of the soils surface for stability and access to oxygen. /Count 17 /CS /DeviceRGB Invasive animals can also pose a threat to mangrove forests. Insects, like ants and beetles, will shred most of the leafy matter into tiny pieces with the help of protozoans and little crustaceans called amphipods.

As the trees grow they take the carbon from carbon dioxide and use it as the building blocks for their leaves, roots and branches. These adaptations are so successful that some mangroves are able to grow in soils that reach salinities up to 75 parts per thousand (ppt), about two times the salinity of ocean water. endobj >> In 1918, their most northern limit was Miami. /CS /DeviceRGB Mangrove forests are important feeding grounds for thousands of species and support a diverse food web.

In fact, the various species of mangroves aren't necessarily closely related to one another, but they do share the unique capability of growing within reach of the tides in salty soil. However, rising temperatures and sea level due to climate change are allowing mangroves to expand their ranges farther away from the equator and encroach on temperate wetlands, like salt marshes.
