Mangroves are hardy shrubs and trees that thrive in salt water and have specialised adaptations so they can survive the volatile energies of intertidal zones along marine coasts A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species.
What is the importance of the mangroves?
Importance And Role Of Mangrove Ecosystems: Mangroves are not only important but crucial for the coastal areas. The most important role of mangroves is that they protect vulnerable coastlines from waves because they hold the soil together and prevent coastal erosion. Mangroves shield inland areas during storms and minimize damage.

Despite their importance, mangroves are being deforested at an unprecedented rate, and due to human pressure and rising seas, are forecast to disappear in as little as 100 years.
What does a mangrove tree eat?
The food chain of a mangrove forest relies heavily on the recycling of the detritus, made by the falling leaves of the trees. This role is mainly filled by the smaller creatures, such as the burrowing crab and the snapping shrimp. Others like the tube worm and bristle worm also do this.
What are mangroves in simple words?
Mangroves are a group of trees and shrubs that live in the coastal intertidal zone. Mangrove forest in Loxahatchee, Florida. There are about 80 different species of mangrove trees. All of these trees grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate.
What are mangroves used for?
Mangroves have been exploited for timber for building dwellings and boats and fuel-wood for cooking and heating. Palm species are used, especially in Southeast Asia and Brazil, to construct jetties and other submerged structures because they are resistant to rot and to attack by fungi and borers.
How is a mangrove formed?
Mangrove sediments form near the mouths of rivers, where abundant land sediments and organic matter are deposited in areas protected from tides and high-energy waves. These sediments are rapidly colonised first by plants and then mangrove trees.

What is special about mangroves?
In addition to being a marginal ecosystem, a mangrove is unique in that, as an ecosystem it has various interactions with other ecosystems, both adjoining and remote in space and time. Another unique feature of mangroves is that, unlike most marginal ecosystems, they are highly productive and dynamic.
What do mangroves need to survive?
cope with salt: Saltwater can kill plants, so mangroves must extract freshwater from the seawater that surrounds them. Many mangrove species survive by filtering out as much as 90 percent of the salt found in seawater as it enters their roots. Some species excrete salt through glands in their leaves.
Can mangroves grow in freshwater?
Salinity Levels As facultative halophytes, mangroves do not require saltwater to survive. Most mangroves are capable of growing in freshwater habitats, although most do not due to competition from other plants.
Where do mangroves usually grow?
Mangroves are defined as assemblages of salt tolerant trees and shrubs that grow in the intertidal regions of the tropical and subtropical coastlines. They grow luxuriantly in the places where freshwater mixes with seawater and where sediment is composed of accumulated deposits of mud.

Mangroves are also ecological bellwethers and their decline in certain areas may provide early evidence of serious ecological threats including rising seawater levels, excess water salinity, overfishing and pollution.
What happens when mangroves are lost?
Coastal Erosion: The destruction of mangroves is contributing to coastline erosion from sea surges. 4. Global Warming: Mangrove destruction will release more carbon into the atmosphere leading to global warming.
How are mangrove forests used by humans?
Mangroves play a vital role in coastal protection by preventing shoreline erosion, reducing sedimentation in coastal waters, absorbing pollutants and improving soil chemistry.
What would happen without mangroves?
A world without mangroves would likely mean a world with fewer fishes, more coastal damage, and unknown ecosystem and public health consequences related to changes in pollutant, sediment and carbon cycles.
What is the main use of wood from mangrove trees for humans?
Mangrove wood is often preferred for use as a cooking fuel and for construction of fish traps, wharves, fences, and roofing (Brown and Fi- scher 1918; Lacerda 1993).
What are mangroves? What are their functions?
What are mangroves? Mangroves are tropical trees that thrive in conditions most timber could never tolerate — salty, coastal waters, and the interminable ebb and flow of the tide. With the ability to store vast amounts of carbon, mangrove forests are key weapons in the fight against climate change, but they are under threat worldwide. By protecting mangroves, we can help protect the future of our planet.
Why are mangroves important?

They also provide a source of livelihood for many humans around the world, including wood for fuel, charcoal and timber and areas for fishing. Mangroves also form a buffer that defends coastlines ...
Where Are Mangrove Swamps?
Mangrove trees grow in intertidal or estuarine areas. They are found in warmer areas between the latitudes of 32 degrees north and 38 degrees south, as they need to live in areas where the average annual temperature is above 66 degrees Fahrenheit.
What Marine Life Are Found in Mangroves?
Many types of marine and terrestrial life utilize mangroves. Animals inhabit the mangrove’s leafy canopy and waters underneath the mangrove’s root system and live in nearby tidal waters and mudflats.
Why is it important to preserve mangroves?
Conservation of mangroves is important for the survival of mangrove species, humans and also for the survival of two other habitats – coral reefs and seagrass beds .
Why do mangroves have leaves?
The roots of mangrove plants are adapted to filter salt water, and their leaves can excrete salt, allowing them to survive where other land plants cannot. Leaves that fall off the trees provide food for inhabitants and breakdown to provide nutrients to the habitat.
What are the threats to mangroves?
Natural threats to mangroves include hurricanes, root clogging from increased water turbidity, and damage from boring organisms and parasites. Human impacts on mangroves have been severe in some places, and include dredging, filling, diking, oil spills, and runoff of human waste and herbicides.
How do mangroves help the environment?
Mangroves’ strong roots help prevent erosion by trapping sediment in their tangled roots. They also become incredibly important during storms: their roots can help break up wave energy and decrease storm surge. According to a recent report, every 330 feet of mangrove forest can reduce wave height by up to 66%. Lastly, they are an important part in the fight against climate change: worldwide, mangroves can sequester, or store, more than 28 million tons of carbon every year. One acre of mangrove alone can sequester 1,450 pounds of carbon a year, which is the amount of carbon produce by driving your car across the United States three times!
What is a mangrove tree?
A mangrove is a type of coastal tree that can live in harsh saltwater environments. When there are many mangroves living together, it’s called a mangrove forest. Florida alone has 469,000 acres of mangrove forest, making it a staple ecosystem of coastal zones.

What are the animals that live in mangroves?
Mangroves’ dense root systems provide perfect hiding places for small animals, and they serve as nursery habitat for many fish, shellfish and crustaceans. Some very commercially- and recreationally-important fish species rely on mangrove habitats for protection, including sheepshead, tarpon and red drum. Other animals live directly on the roots, including snails, barnacles and oysters.
How cold can mangroves get?
Mangroves don’t like cooler temperatures, so you will rarely find mangroves beyond about 25 degrees latitude north or south, however warming temperatures due to climate change could cause their range to expand northward.
Do mangroves live on beaches?
Mangroves like to live on tropical coastlines—and so do people. Unfortunately, that means many mangrove forests are dozed to make way for coastal development, sandy beaches and aquaculture (in particular, shrimp farming has led to large mangrove losses).
Why are mangroves important?
Mangroves are also very important for protecting our oceans and shorelines. Mangrove forests are home to a large variety of fish, crab, shrimp, and mollusk species. Their roots create an underwater habitat for marine life on the coasts, often acting as ‘nursery areas’ for young fish, keeping them safe from threats.
Why are mangrove forests important ecosystems?
Mangroves have the ability to store vast amounts of carbon which is vital as we combat climate change . This is why mangrove-planting projects are so essential, and why we need to ensure that destruction of mangroves is limited.
What are the threats to mangroves?
One of the main threats to mangrove forests is shrimp farming. Hundreds of thousands of acres of wetlands where mangroves live have been cleared in order to make room for artificial ponds that are stocked with shrimp. This then affects the water quality and flow along the coastlines, so that mangroves can no longer survive here, even after the ponds are cleared.
