When threatened, they flee to the water, where they can select from a different menu of food. Microbes, being an important component of the mangrove environment, not only play a very critical role in creating and maintaining this biosphere but also serve as a source of biotechnologically valuable and important products. The underground portion of the root adds stability while the looping projections increase access to the air. endobj But, take away the super cold freezes and the young mangroves are able to survive the winter. Initially toxic from the deep, acidic soil coming into contact with the air, the mounds eventually lose their acidity and become excellent places for little mangroves, including several species of the mangrove fern Acrostichum, to grow.
