Why are mangroves considered to be special?
Mangrove plants require a number of physiological adaptations to overcome the problems of low environmental oxygen levels, high salinity, and frequent tidal flooding.Each species has its own solutions to these problems; this may be the primary reason why, on some shorelines, mangrove tree species show distinct zonation.

Why should we protect the mangrove?
Why should we protect mangroves? We should protect mangroves because they protect us from big waves and storms. They are home for many marine animals. They also provide food to many animals. They protect us from erosion. They give us fresh air and they keep our world in balance. The reason we should protect mangroves is because they protect us.
Why do mangroves have large root systems?
The mangroves' massive root systems are efficient at dissipating wave energy. Likewise, they slow down tidal water enough so that its sediment is deposited as the tide comes in, leaving all except fine particles when the tide ebbs. In this way, mangroves build their environments.

What will happen if there are no 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.
Can mangroves save the world?
Using mangroves as sea defences is five times more cost-effective than man-made alternatives. They are also vital in the battle against climate change itself. Mangrove ecosystems are powerful carbon sinks, sucking up carbon dioxide from the air to store in their roots and branches.
What are the 5 importance of mangroves?
Mangroves protect shorelines from damaging storm and hurricane winds, waves, and floods. Mangroves also help prevent erosion by stabilizing sediments with their tangled root systems. They maintain water quality and clarity, filtering pollutants and trapping sediments originating from land.
What are 4 effects of mangrove deforestation?
Other more striking effects of mangrove deforestation include a decreased availability of wood, fish and prawn, less revenue paid to government in terms of royalties and tourist fees, an increase in coastal erosion and eventual reduction of seagrasses and coral reefs.
What will happen if all mangroves are removed from estuaries?
If mangroves were removed from the estuarine area, it is possible that the deterioration in water quality could impair the services provided by the seagrass and coral reef communities3.
How do mangroves affect the environment?
Mangrove forests like this may be one of the world's most underappreciated landscapes. They provide important habitat for a wide variety of terrestrial, estuarine and marine species — from fish to birds and manatees — and supply nutrients and sediments for seagrass-bed and coral-reef habitats.
What could happen to us if we did not protect our mangrove forests?
Global destruction of mangrove forests impacts biodiversity, food security, and the lives and livelihoods of some of the most marginalized communities in the world, according to the United Nations Environment Program (UNEP).
Why are mangroves important to the ecosystem?
As well as providing crystal clear waters for corals to survive, mangroves also allow seagrass beds to flourish. Seagrass beds act as an intermediate environment for fish between mangroves and the reef. When ecosystems are healthy and well connected, juvenile fish grow up in mangrove nurseries, spend their adolescence in the seagrass before finally venturing out into adulthood on the reef. The long blades of grass and shallow waters in seagrass beds provide more protection for young fish from predators than coral reefs. Many species of juvenile sharks grow up in seagrass beds because they would be too vulnerable out on the reef. The connection of the three habitats: coral reefs, seagrass and mangroves form a crucial connectivity of ecosystems, that million of people depend on.
How do coral reefs survive?
Corals survive because of microscopic algae that live inside it and use solar energy to photosynthesise, providing their host corals with enough energy to build and rebuild the coral structure. They also provide corals with their many distinctive colours.
Why do corals need mangroves?
Mangroves provide corals with just that by acting as natural water-treatment plants. They stand sentinel between the land and sea, stabilising the shoreline to prevent coastal erosion and removing pollutants from the water. Their complex root systems trap everything that would otherwise drift out to nearby reefs and smother unsuspecting corals. Without mangroves, coral reefs will die.
What does every tree do for the environment?
Every single tree you help us plant, will create jobs, protect coral reefs and fight climate change.
Why do mangrove forests grow vertically?
This causes the river to drop all of the soils and organic matter it was transporting. In many locations, these soil deposits grow vertically at rates of up to 10mm per year, actually creating more land. This allows local areas to combat the negative impacts of sea level rise and further protect their coastlines from being lost to the sea.
Why do mangroves anchor themselves?
Mangroves living closest to the sea have evolved large root systems that anchor themselves and stabilise the mud around them to protect their forest from incoming waves.
How do mangroves protect the land?
The complex root systems of mangrove forests protect the land behind them by acting like a barrier between land and sea. They reduce the height and energy of incoming waves so that by the time they reach land they aren’t as powerful and destructive. This prevents huge amounts of damage by waves and storms to people’s homes and other valuable infrastructure like roads, schools and farms. This saves entire communities and numerous industries millions of dollars in damage every year.
What is a mangrove?
Actually the term mangrove can refer to several related but distinct subjects depending on the context. In its broadest sense, a mangrove, or mangrove forest or mangrove swamp, is a specific type of ecosystem found in coastal areas or near estuaries. The plants that grow in a mangrove have evolved to cope with changing tides and the high degree of salinity in the water. More specifically, a mangrove tree is a member of Rhizophoraceae, which may be referred to as the mangrove family of plants. Some scientists are even more particular about the usage of mangrove and exclusively use it only for species in the genus Rhizophora (within Rhizophoraceae). Not all plants in a mangrove swamp are mangrove trees, but due to the dominance of said trees, the entire assemblage of plants in the swamp is collectively called a mangrove.
Where can you find mangroves?
Mangroves are found in brackish water near coastlines in many tropical and subtropical countries. The majority are located between latitudes 25° N and 25° S. The Great Sundarbans in the Bay of Bengal is the largest mangrove region in the world and a UNESCO World Heritage Site. It is straddled between India and Bangladesh, covering parts of Bangladesh's Khulna Division and the Indian state of West Bengal. As you can see from the map, mangroves are also found throughout Southeast Asia and parts of Oceania.
Is Malaysia a mangrove country?
Malaysia is blessed to have mangrove forests along its shores. Unfortunately, most of them are threatened by urban development, particularly in the state of Selangor which once boasted large swathes of mangrove swamps.
Why are mangroves losing their habitat?
Much of this loss is due to human behavior — deforestation for development, unsustainable aquaculture, agriculture, and timber harvesting. As sea level rises, mangroves are no longer able to retreat inland because they run up against human-developed structures. The loss of mangrove habitats has big consequences. Coastal areas are at risk, important animal habitats disappear, the lives and livelihoods of millions of people around the world are threatened, and carbon dioxide is released into the atmosphere.
Why are mangroves considered blue carbon?
Mangroves, along with seagrasses and salt marshes, are called blue carbon ecosystems due to their ability to sequester large amounts of carbon from the atmosphere. In fact, blue carbon systems are estimated to sequester carbon at a faster rate than land forests, even though they cover less area on the globe. Preserving these blue carbon ecosystems, and restoring habitats that have been lost, is critical to slowing the impacts of climate change.
Why sponsor a mangrove tree?
Sponsor the planting of a mangrove tree as part of the Million Mangroves Project when you purchase a Two Trees pencil. Healthy mangrove forests protect important coastal habitats and help fight climate change by sequestering carbon.
How do mangroves survive in salt water?
All mangroves have evolved special adaptations that enable them to live in the harsh, dynamic environment between the sea and land. The muddy soil that mangroves live in lacks oxygen, so mangroves have developed their own type of snorkel that allows them to breathe. An aerial root called a pneumatophore shoots up vertically from the ground and emerges above the water level providing the tree access to oxygen. On the trunk above the water line, mangroves also have pores (called lenticels) that allow the tree to absorb oxygen. Instead of having a deep tap root like many trees, mangroves use a web of sprawling cable roots for support. And because they are often submerged in salty or brackish water, mangroves must also tolerate salt. Some species exclude salt from entering their roots, while others can excrete salt from inside the tree through their leaves.
Why are mangroves important?
Due to their location, mangrove forests are key to protecting coastal communities from crashing waves, storms, and flooding. This natural defense system is more important as storm intensity and frequency increase due to climate change. The dense root structure of mangroves also helps to trap muddy soil, slowing coastal erosion and preventing runoff from deteriorating the water quality of nearshore habitats like coral reefs. Unfortunately, in many places mangroves have been cleared to make room for development, agriculture, or aquaculture which leads to more erosion and less protection from storms.
Why is it important to protect and restore mangrove habitats?
Protecting and restoring mangrove habitats is critically important to ensure a sustainable seafood supply, protect coastal communities from the impacts of climate change, and sequester large amounts of carbon.
How do you support the Million Mangroves Project?
Each pencil purchased pays for a mangrove tree to be planted and maintained as part of the Million Mangroves Project. Funds from the sale of this pencil also help support the Aquarium's global conservation efforts. After you’re done using this pencil, plant it in a container to grow your own tree.
