During past changes in sea level, mangroves were able to move further inland, but in many places human development is now a barrier that limits how far a mangrove forest can migrate. Dwarf, or scrub, mangrove forests only attain canopy heights of less than 5 feet (1.5 meters) although they contain the same species as the other types of forest. This hoarding of water creates thick and fleshy leaves, a characteristic called succulence. /Font << Producers - These are autotrophic organisms which make their food through photosynthesis. They protect the climate by absorbing carbon dioxide and reducing the amount of greenhouse gases in the atmosphere. The tree and shrub foliage create a rich habitat for other plants and animals to call home, and the branching root system underwater creates a safe haven for many fish, especially easily preyed upon young. In 2016, the United States imported over 1.3 billion pounds of shrimp, and it is estimated that Americans consume 4 pounds of shrimp per person every year. Mangrove trees can be distantly related and are grouped together for their shared characteristics rather than true genetic ties. Under the strictest guidelines, there are roughly 54 true species of mangrove belonging to 16 different families.

Since leaf cells can hold a large volume of water when compared to all other cells, salt is drawn to the leaves as a mechanism to balance the salt concentration.

Dive underwater in the surprisingly clear waters that typify many mangrove forests, and amangroves smooth brown rootssuddenly take on the textures and hues of the multitude of marine organisms clinging to its bark. Perhaps, the initial few seedlings to colonize the north were extremely early reproducers and the trait has been passed down to the current generation. After the shrimp reach maturitya time that takes between three to six monthsthe ponds are drained so the shrimp can be harvested, and toxic water that contains the shrimps waste, uneaten shrimp feed, pesticides, chemicals, and antibiotics is released into the surrounding environment where it can harm local ecosystems. << The Mangrove Alliance is a group spearheaded by the German Federal Ministry for Economic Cooperation and Development, the World Wide Fund (WWF) and the International Union for the Observation of Nature (IUCN) that aims to increase global mangrove forests by 20 percent by 2030. endobj /ProcSet [/PDF /Text /ImageB /ImageC /ImageI] 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.
