Mangrove Ecosystems

A mangrove is a shrub or a small tree growing in salt and brackish coastal waters. The concept also applies to the tropical coastal vegetation of these species. Worldwide, mangroves occur between latitudes 25° N and 25° S in the tropics and subtropics. In 2000 there were 137,800 square kilometers of mangrove forests worldwide, covering 118 countries and territories. Salt resistant, also known as halophytes, mangroves adapt to live in severe coastal conditions. They have a complex salt filtration system and a complex root system to deal with the dip and wave motion of saltwater. They adjust for waterproof mud’s low oxygen conditions.

Why are mangroves so important?

It discovers the mysteries of nature in enchanted woods. The links between land and sea and nature and people are straddling. Forests of mangroves nurture our estuary and fuel our natural economies.


For the environment, mangroves are also essential. Their thick roots help tie and build soils. Its overseas origins slow down water flows and promote coastal erosion reduction in sedimentary reservoirs. The complex root systems of mangroves filter nitrates, phosphates, and other water contaminants into the estuarine and ocean environments to improve the water quality of the rivers and rivers.

For centuries, mangrove forests absorb large quantities of carbon dioxide and greenhouse gas emissions from the atmosphere, trap, and store in their carbon-rich, flooded soils. This is a vital service of the environment in the face of climate change. This entered biomass, known as ‘blue carbon,’ contains coastal habitats such as mangroves, seagull beds, and salt ponds.

Mangrove forests offer a wide range of animals such as birds, fish, invertebrate species, mammals, and plants as habitats and shelters. Estuarine habitats with shorelines of coastal mangroves and tree roots are also valuable breeding areas and nurseries for marine youth species, including shrimps, crabs, and several species, such as redfish, snook, and tarpons. Mangrove branches act like rookeries of birds and nesting places for the egrets, herons, cormorants, and roseate coves on the coast. Red mangrove roots can. In some areas, oysters stick to the section of the roots hanging in the water. Endangered animals, such as sawfish with tiny diamonds, manatee, hawksbill sea turtle, Key Deer, and the panther in Florida, rely on this habitat in their life cycle.


For people, like birding, fishing, snorkeling, kayaking, swimming, paddling, and therapeutic peace and relaxing come from a quiet time in nature. Mangrove forests have nature experiences. They also provide communities as a nursery for trade fish stocks with economic benefits.

Ocean – Coral bleaching

Coral bleaching is one of the most damaging consequences of climate change. This summer, the blanching of the Great Barrier Reef in Australia is the headline. Still, this pattern takes place in all oceans in the world, and scientists are planning that it will intensify as oceans consume more carbon. The possibility of their demise is a tragedy for our oceans as coral reefs are the pillar of marine life. While reefs and coastal forests classify as distinct ecosystems, nature does not accept this border. Young corals grow between mangrove roots, and healthy forests may protect coral species at risk of coral bleaching extinction. In addition, mangroves may also contribute to a reduction in ocean acidification that prevents coral bleaching.

Black Mangrove

The Black Mangrove is more like a tree than the spidery Red Mangrove (formerly known as Avicennia nitida). A silver-green mangrove and a dark trunk able to grow  up to 30-40 ft (9-12m) high. You can see on the surface crystals of salt if you look closely at the leaves of the Black Mangrove. This is a way for Black Mangrove to survive in a saltwater world that kills other plants. You can take saltwater, use the water, and put salt on your leaves.

The Black Mangrove has also adapted to its surroundings by making roots sticking out of the sediment rather than creating. Researchers refer to these roots as pneumatic drugs, which means “air-breathing roots.” The Black Mangrove has formed these roots, which function as snorkels so that they can take the air, even if in seawater or soggy mud. All plants have to respire.

Black mangroves, accompanied by green tear-drop-shaped plants, have white flowers in spring and summer. When they have washed off a right bank, they slip off the plant and float on the surface of the ocean. In contrast to the Red Mangrove, seeds of black mangrove are not produced in water, so black mangroves are often higher up the shore than red mangroves.

Why are mangroves dangerous?

The rapidly developing shrimp aquaculture industry is by far the biggest threat to the world’s mangrove forests. Someone densely covered the artificial ponds with shrimp clear of hundreds of thousands of acres of significant wetlands. Shrimp farmers are digging channels to provide vast amounts of freshwater and seawater for ponds. These divestments change the natural water flow, which maintains mangrove environments and inland and offshore ecosystems. Entertaining water can damage mangroves by preventing their seeds from being spread by marine water, and by cutting down freshwater sources, it can destroy the trees. Seawater will contaminate the farmland or the freshwater under the ground if diverted inland. Shrimp farmers also use large quantities of pesticides and antibiotics to avoid shrimp overcrowded. This chemical soup contaminates the surrounding freshwater and coastal waters along with vast amounts of agricultural waste.

It is a massive waste to capture wild shrimp larvae to store the tanks. Fishers use nets that destroy the ocean and catch several species and shrimp, causing damage to marine habitat and depleting local fish. Shrimp aquaculture also has high social costs. Farming shrimp can deplete the capacity of local people to sustain themselves rather than support local economies. Shrimp is a cash crop, not a livelihood crop so that shrimp income export and jobs are typically temporary. Just two or five years until pollution and disease cause the average Asian intensive shrimp farm to shut down. Local people live in a ravaged countryside that can no longer sustain fishing, agriculture, wood collection, and many compels to move abroad.

Mangrove forest

There are approximately 80 mangrove species. They cultivated all these trees in areas with low oxygen, in which slow waters permit the accumulation of fine sediments. Mangrove forests only expand along the equator at rainy and subtropical latitudes because freezing temperatures cannot withstand.

It can recognize the thick tangling of prop roots that make trees look standing on stilts above water for many mangrove forests. The tangling of roots causes the trees to deal with tides every day, which ensures that they flooded most mangroves twice a day. The roots often delay tidal water movements, leading to sediments coming out of the water and building a muddy ground.

Mangrove forests are stabilizing the shoreline, reducing storms, currents, waves, and tides erosion. The complex root system of mangroves also attracts fish and other species looking for food and refuge from predators.
