Since 2016, the International Mangrove Day has been celebrated on July 26.

According to UNESCO, mangroves are a “unique, special and vulnerable ecosystem”.

In this article, you’ll learn what mangroves are, 7 vital functions, their threats and 4 more mangrove facts to share with your friends.

Let’s start with the basics and the question of what mangroves are.

What are mangrove forests?

Some people think that a mangrove is a tree species like a birch or a beech.

*cough*

Okay, okay, by “some” I mean myself, because that’s what I thought before I started planting trees with Click A Tree.

But now I know better and am happy to share my newfound knowledge with you.

Mangroves are tropical plants and trees that live in tidal environments.

You will find them where the coast meets the sea or other bodies of water.

Although mangroves can live in salt water, they do not need it to survive.

In short, mangrove forests are the collection of trees and shrubs that grow between water and land.

With their large roots emerging from the ground, they are not only a magical sight, they also bring with them many vital benefits for humans, animals, the sea and our planet.

7 amazing facts about mangroves

As already mentioned, mangroves are extremely valuable. Otherwise there would probably be no Mangrove Day.

Here are 7 of the extremely valuable functions that mangroves perform.

Fact #1: Mangroves protect coasts from land erosion

At the same time, mangroves protect the coast from the constant land erosion of the sea.

Fact #2: Mangroves stop tidal waves

Mangrove forests reduce the risk of flooding by absorbing water from heavy rainfall and storm surges.

They also serve as natural breakwaters. They stop or weaken tidal waves.

The areas behind mangroves usually get off very lightly during tsunamis.

Where the mangroves have been cut down, the tidal wave sweeps everything away far inland.

Mangroves therefore protect everything behind them: from people and houses to wild animals.

Fact #3: Protection of underwater life

Many marine creatures need mangrove forests to survive.

The water surrounding the roots is rich in nutrients and safe for young underwater animals.

Milkfish and shrimps, for example, spend their childhood days here, protected from predators.

Fact #4: You create a home for wild animals

But they also provide protection for wild animals on land.

In the Philippines alone, where we plant mangroves and collect plastic, for example, there are more than a hundred mammals and over 170 bird species that cannot be found anywhere else in the world.

We think this is worth protecting. What do you think?

Fact #5: Mangroves reduce pollutants

Mangroves not only protect the coast from storms and tidal waves.

They are also a powerful water filter.

Mangrove roots filter pollutants out of the water before they can reach coral reefs and seagrass beds.

Fact #6: Mangroves are climate heroes

Every hero has their own holiday. Mangrove Day exists because mangroves are real climate heroes.

They are among the most valuable carbon stores on our planet.

We keep our calculations conservative. But an average mangrove tree absorbs almost 300 kg of CO2 over 25 years!

Not so much in the first few years, of course.

But in their best years, mangroves store up to 50 kg of carbon per year!

Fact #7: Creating jobs and opportunities

Planting trees means creating jobs and opportunities for local people.

At Click A Tree, we are proud to work with many dedicated people.

They are paid fairly for their dedication and hard work.

It is only holistically sustainable if all parties involved benefit.

And only then can it work in the long term.

The local people not only plant the mangrove trees, they also care for and protect them.

That is why our mangroves in the Philippines have an incredible survival rate of 93%.

Why is there a Mangrove Day?

Now for the sad part.

Although mangroves have so many great and vital benefits, the size of mangrove areas is shrinking.

This is the only reason why Mangrove Day exists at all. To generate attention.

It’s nice that it has worked out with you before.

Now use your power and share these mangrove facts to help more people learn about the value of mangroves!

Threats to mangrove forests

Sad fact: around a third of all mangrove forests worldwide have been destroyed since 1980¹.

The main causes of the loss of these forests are man-made:

  • Trees are being removed to improve the quality of the beach and to build tourist resorts.
  • Trees are also being removed because they are incompatible with the many shrimp farms in operation (harmful chemicals are used in the waters).
  • Swamps are being drained, i.e. mangrove trees are being removed to make room for human settlements.

Because there is no foothold in sight, forests have no chance to take their natural course and rebuild themselves.

That’s why our mission is to restore native tree species, create habitat and provide full-time employment with a fair salary.

Where Click A Tree plants mangroves

Our tree planting in the Philippines takes place on Mindanao Island, the second largest island in the country.

Figuratively speaking: Mindanao is bigger than Portugal.

To be more precise, we plant our mangroves in Balete Bay, near Sleeping Dinosaur Island.

In addition, we collect 1 kg of plastic from the sea for every mangrove planted.

Here you can find exact coordinates and further details about our mangrove project in the Philippines.

4 unique and amazing mangrove facts

Would you like to impress your friends with your knowledge of nature?

These 4 mangrove facts will help you!

1. friends of salt

Mangroves are the only tree species that can tolerate salt water.

If they absorb too much salt, they simply excrete it through their leaves.

2. a safe place for underwater life

The underwater roots and branches create a safe space for underwater life, including many species of fish, crabs, shrimps and other crustaceans.

3. mangrove species: How many mangrove species are there?

Depending on what someone calls a mangrove, it is estimated that there are between 54 and 80 species of mangrove ².

Scientists and researchers cannot agree on the number of species, as a distinction must be made between a true mangrove and a “mangrove associate”.

A mangrove associate tolerates salt water, but lacks other characteristics that a true mangrove has.

4. they come in different shapes and sizes

Mangrove species come in all shapes and sizes.

From small shrubs to tall trees of 63 meters³.
