Well, they preserve the shoreline by preventing erosion, they filter pollutants, they absorb excess water, lessening surface runoff and flooding, and they’re a important and unique ecosystem for many plants and animals. So let’s talk about the plant that makes mangrove forests so popular, so famous, the mangrove trees.

Which of the following is a benefit of having a healthy salt marsh? Salt marshes provide a habitat for juvenile fish.

The correct answer is (b) Many fishes breed in mangrove forests. The most important reason for a fisherman to support the protection and restoration of mangrove is that mangroves serves as a breeding habitat for the fishes and helps to increase the number of fishes which is beneficiary for them.

Explain why traditional views about mangrove forests helped lead to their degradation. Traditionally mangrove forests were viewed as wastelands and unhealthy environments. People therefore reasoned that their removal would improve the health of their ecosystems.

Mangroves are important to people because they help stabilize Florida’s coastline ecosystem and prevent erosion. Mangroves also provide natural infrastructure and protection to nearby populated areas by preventing erosion and absorbing storm surge impacts during extreme weather events such as hurricanes.

Mangroves are the first line of defense for coastal communities. They stabilize shorelines by slowing erosion and provide natural barriers protecting coastal communities from increased storm surge, flooding, and hurricanes.

Mangroves protect both the saltwater and the freshwater ecosystems they straddle. The mangroves’ complex root systems filter nitrates and phosphates that rivers and streams carry to the sea. They also keep seawater from encroaching on inland waterways.

Root systems that arch high over the water are a distinctive feature of many mangrove species. In addition to providing structural support, aerial roots play an important part in providing oxygen for respiration. Oxygen enters a mangrove through lenticels, thousands of cell-sized breathing pores in the bark and roots.

White mangrove fruit are not edible. And the poor Buttonwood, Conocarpus erectus, (kawn-oh-KAR-pus ee-RECK-tus) never viewed on its own. The Buttonwood makes a nice landscape tree, is high in tannin and can be used to make a smokeless, high grade charcoal.

Mangroves can and will live and grow completely under water. You will see little air bubbles on their leaves if there is very very little flow.

You can start growing mangrove trees in your backyard if you live in U.S. Department of Agriculture plant hardiness zones 9-12. If you want an impressive potted plant, consider growing mangroves from seed in containers at home. Red mangrove (Rhizophora mangle) Black mangrove (Avicennia germinans)

Do mangrove trees need salt to grow then? No. They continue to grow with freshwater but more slowly. So, outside their specialised niche, they cannot compete with regular plants and are quickly overgrown.

Coastal mangrove forests are resilient, tolerating salt, powerful waves and even rising seas. But new research suggests that when sea levels rise too quickly, the mangroves can drown.

The trees play a vital role in storing planet-heating carbon dioxide and protecting communities from storms and coastal erosion. Mangrove forests will be in danger of dying out when sea levels rise by more than 6 millimeters per year, the study published in the journal Science found.

Sea level rise poses a major threat to mangrove ecosystems through sediment erosion, inundation stress and increased salinity at landward zones. These problems will be exacerbated for mangrove stands that are subjected to ‘coastal squeeze’, ie where landward migration is restricted by topography or human developments.

Temperature: “Increased surface temperature is expected to affect mangroves by (Field, 1995; Ellison, 2000): Changing species composition (extinction); Changing phenological patterns (e.g., timing of flowering and fruiting); Increasing mangrove productivity where temperature does not exceed an upper threshold.

Changes in climate and other factors may also affect mangroves, but in complex ways. Global warming may promote expansion of mangrove forests to higher latitudes and accelerate sea-level rise through melting of polar ice or steric expansion of oceans.

Mangroves grow along shorelines, and they protect coastal areas from erosion and storm surge. They also store large amounts of carbon, which helps slow climate change.

Mangrove Threats and Solutions

• Shrimp Farming. By far the greatest threat to the world’s mangrove forests is the rapidly expanding shrimp aquaculture industry.
• Tourism. Tourism is a booming industry and an important source of income in many developing nations.
• Agriculture.
• Coastal Development.
• Charcoal and Lumber Industries.

More than one in six mangrove species worldwide are in danger of extinction due to coastal development and other factors, including climate change, logging and agriculture, according to the first-ever global assessment on the conservation status of mangroves for the IUCN Red List of Threatened Species™.

The major threats to mangrove forests include population explosion, conversion to aquaculture ponds, clear-felling for timber, charcoal and wood chip production for industrial and urban development.

Herbicides, oil spills, and other types of pollutants may kill mangroves. Causing tremendous damage to mangroves, herbicides, oil spills, and other types of water pollution may result in the death of these plants.

If you want to remove any mangroves on your property, then you may have to apply for an Individual permit, and mitigation may be required.

Mangroves store more carbon than terrestrial forests. Mangroves help people weather the impacts of climate change — but they also help mitigate its causes. Globally, protecting forests can account for as much as 30 percent of the solution to climate change thanks to their ability to absorb and store carbon dioxide.

Other ecosystems nearby, like coral reefs, also depend on mangroves. Tragically, we’ve underestimated the value of this quiet, unflashy forest that turned out to be one of the most productive ecosystems on the planet. But it’s not too late.

Requirements for the development of mangroves are:

• Average temperatures of the coldest month higher than 20°C; the seasonal temperature range should not exceed 5°C.
• A fine-grained substrate.
• Shores must be free of strong wave action and strong tidal currents.
• Saline water; they are facultative halophytes.

The main drivers of this loss were clearing for aquaculture, rice production, and oil palm plantations. The authors caution more mangroves will be deforested unless policies change.

Snails, barnacles, bryozoans, tunicates, mollusks, sponges, polychaete worms, isopods, amphipods, shrimps, crabs, and jellyfish all live either on or in close proximity to mangrove root systems. Some invertebrates thrive in the mangrove canopy, of which the most abundant are the crabs.
