Bintan Island is the largest island in the Riau Archipelago, Sumatra, Indonesia, covering 1,173 square kilometers. Located just 40 kilometer or a short sail from Singapore, the island offers breathtaking coastal landscapes. Beyond its white sand beaches, which serve as nesting grounds for sea turtles, Bintan is also home to extensive mangrove forests and seagrass meadows. 

Spanning 8,553 hectares of mangrove forests and 2,094 hectares of seagrass meadows, these ecosystems serve as vital habitats for diverse wildlife, including endangered species dugong (Dugong dugon). Together with the surrounding coral reefs that support abundant marine biodiversity, Bintan’s coastal ecosystems create vibrant natural sanctuary. Not only critical for wildlife, but these ecosystems also support the livelihoods of local communities, most of whom depend on fisheries and tourism. 

“Most of us have been fishers for generations, relying heavily on fisheries and other marine resources. However, later, we have discovered another potential in our village. We have a magnificent coastal and marine landscape that we realized could be developed further through environmental services, particularly as a tourism attraction,” said Iwan, leader of the Conservation Education Group of Pengudang Village, one of the coastal villages on Bintan Island.

Mangrove Degradation in Bintan Island 

Located near Singapore, Bintan Island stands both a strategic gateway and a leading tourist destination, known for its luxury resorts. However, decades of tourism and development have come at an environmental cost. Many coastal areas face increasing human-driven pressures. Between 2014 and 2021, more than 450 hectares of mangroves were lost due to tourism expansion, industrial development, and aquaculture – placing serious strain on ecosystems and coastal communities.

The open coastline of Pengudang Village, once dense with mangrove cover, now remains exposed – without mangrove barriers.

“Most of Bintan Island is surrounded by the sea, and the mangrove ecosystems condition is concerning. There has been significant damage along the coastal areas,” said Khoirum Minan, Project Manager of Trees4Trees. He explained that many mangrove areas are now severely degraded and require restoration to restore their cover. 

Iwan also acknowledged that mangrove deforestation caused by business expansion and the island residents’ growing needs has been significant. “Coastal communities and mangroves are interconnected. If mangrove cover disappears, it will not only affect the environment but also the well-being of communities. Therefore, restoration is a must – and we have started it,” said Iwan.

Planting Mangroves: Green Action of Industrial Bank of Korea and Copion 

Recognizing the urgent need to restore coastal ecosystem health, local communities on Bintan Island – particularly in Pengudang Village – have initiated mangrove restoration efforts in recent years. Iwan shared that, together with fellow villagers, they began nurturing mangrove seedlings and replanting degraded areas. 

Supporting these community-led efforts, earlier this year, Industrial Bank of Korea, in collaboration with Copion and Trees4Trees, helped plant additional mangroves along the coast of Pengudang Village. A total of 1,500 Rhizophora apiculate species were planted together with the Industrial Bank of Korea staff members and Pengudang communities. The species was selected as the area is its natural habitat, increasing its chance of growth and survival. 

Restoring mangrove

Beyond restoring coastal and marine ecosystems, the initiative which part of the Industrial Bank of Korea sustainability program also aims to strengthen coastal livelihoods.  

“When we plant mangroves, marine and coastal species such as crabs, shrimps, and fish become more abundant, as mangroves provide essential habitat for them. With healthier ecosystems and increased yields from the sea, we hope mangrove planting will strengthen local fisheries and, in turn, improve the local economy,” said Khoirum Minan.

Strengthening Bintan Island Potential: Sustainable Fisheries and Tourism 

With its strategic location, strong fisheries and tourism sectors, Bintan holds significant potential as a leading coastal destination. For the villagers, their livelihood is not separate from nature.  

According to Iwan, conservation is integrated into every tourism activity in Pengudang Village, including mangrove planting, ensuring that it showcases nature while protects and sustains the surrounding ecosystems. The sea, however, has long been Bintan’s lifeline, providing food and income for local fishers. As part of Indonesia’s Exclusive Economic Zone, the fisheries potential in Bintan Regency exceeds 100,000 tons, placing it among the country’s important fishing regions.

Iwan, the leader of Conservation Education Group of Pengudang Village thanked all of volunteers to help communities in restoring mangrove covers.

“We realized that our tourism offers natural heritage. Mangroves, seagrass meadows, and coral reefs,” said Iwan. “Visitors can glide through our mangrove forests on firefly tours, explore vibrant underwater life while snorkeling, or enjoy coastal village experiences,” he said. “So, as the coast and the sea are inseparable parts of our lives, whether we like it or not, we have to protect them. Because it is essential to our survival,” he continued. 

With the mangrove restoration and sustainable fisheries and tourism practice, the island is potentially become a leading model for sustainable island development, where mangrove restoration, eco-tourism, and community livelihoods reinforce one another.

Community Culture, Interwoven with Mangrove Conservation

Community Culture

Surrounded by over 8,000 hectares of coastal trees and wetlands, Kampung Laut Village is home to the largest mangrove ecosystem in Central Java. This verdant water world in Cilacap Regency supports a rich variety of biodiversity, including over 50 distinct mangrove species.  

For the communities of Kampung Laut (a name which means ‘ocean village’ in the Indonesian language), mangroves are essential. Most of the people here work as fishers and recognize the importance of these trees to ecosystem health and productivity. 

But the mangroves’ value goes further still, with roots reaching deep into local culture; the trees provide natural dyes which can be used in the traditional art of batik textiles, thereby transforming nature’s bounty into both cultural heirlooms and economic opportunities. 

In this article, we explore a nascent artisan industry that has emerged in Kampung Laut, inspired by nature and intrinsically connected to land and culture. 

The Birth of Kampung Laut Batik 

The story of Kampung Laut batik began in 2015 when Sodiqin, leader of the Mekar Canting Batik Group, was inspired by a batik-making program on national television. Together with two neighbors, he began to experiment with techniques and materials until they found the right formula. 

“At first, we used natural dyes from ketapang leaves and jengkol tree bark,” Sodiqin recalls. “But I wanted something unique that represents Kampung Laut. I noticed the fallen Rhizopora mangrove fruits scattered on the roads. We were curious to see if they could be used as natural dyes, as many people had claimed.” 

Sodiqin and his friends started collecting Rhizopora fruits, cutting and crushing them, then drying them under the sun for three days before boiling them. “The entire process of producing the natural dye takes about a week,” he says, “and dyeing the cloth needs another three days to a week; it takes a while, but the results are worth the wait.”

Motifs and Materials Inspired by Nature 

In addition to the distinctive brown hues of Rhizophora mangroves, blended with colors from other local trees, batik designs from Kampung Laut are brought to life through patterns and motifs inspired by the sea and the richness of coastal life. 

As Sodiqin explains, “when we asked ourselves what best reflects Kampung Laut, the answer was simple: mangroves and fisheries.” Designs from the Mekar Canting Batik Group feature fish, crabs, shells, shrimp, mangrove fruits, and underwater scenes. 

Most of their batik fabrics are made using a traditional stamping technique, whereby hot wax is applied to cloth using engraved copper stamps before it is dyed. This method allows the artisans to produce batik more efficiently and replicate patterns more consistently. 

“We also use the hand-drawn technique, but only by special order,” Sodiqin said. “Hand-drawn pieces take longer and require more skill.” This technique involves drawing patterns using a traditional drawing tool called a canting, which is filled with hot wax. It can take months just to complete one piece of batik cloth using this method.

Sustainable Livelihoods, Interwoven with Women’s Empowerment 

What began as the passion project of three individuals has grown into a 20-strong collective, made up mostly of women. Training programs provided by the government and corporate CSR initiatives have strengthened their skills and encouraged more women to join. “It started with women inviting others to learn batik,” says Sodiqin. “Then, through word of mouth, more women have become involved.”  

The rise in popularity of Kampung Laut batik has opened new income opportunities for women in coastal communities. Batik-making provides much-needed earnings, especially during exhibitions or when orders come in. “The income can help women to cover their children’s needs or support other family expenses,” Sodiqin says. 

Nevertheless, marketing remains a challenge. Located in a remote area, accessible only by crossing a lagoon, Kampung Laut has limited access to markets. Most sales come from exhibitions in cities like Jakarta, Yogyakarta, and Semarang. “We tried e-commerce, but delivery is very difficult from here,” he said.

From Ecology to Economy: Healthy Nature Helps Communities to Thrive 

In 2022, Trees4Trees began replanting mangroves in Kampung Laut to restore areas degraded by deforestation. From 2022 to 2023, over 24,000 individual trees were successfully planted. In 2024-2025, with support from our partner, EcoMatcher, 125,000 trees were planted. In October 2025, together with EcoMatcher and GRAB, we are planting an additional 50,000 mangroves in the area. 

“By expanding mangrove cover, our mangrove planting program helps local communities thrive, sustain their livelihoods, and keep their culture alive, including the mangrove batik,” explains Yoga Septian, Trees4Trees Unit Manager of the Cilacap site. “The local community relies on fisheries and mangroves for their living; beyond fishing, they process mangrove fruits into snacks and produce mangrove batik as additional sources of income,” he added.

Healthy mangroves provide numerous benefits to people, nature, and the planet. They produce oxygen, absorb CO2, prevent coastal erosion, and provide essential nurseries for fish. For local people like Sodiqin and his group, these trees also provide materials, livelihoods, and cultural value. 

With that in mind, Sodiqin insists that sustainability is key. “Every time we harvest resources provided by the mangroves, we must also replenish them,” he says, “so they won’t vanish like they did before. The more we plant, the better our lives will be.”

Mangunharjo Wetan is a quiet little village on the north coast near Semarang in Central Java. Here, many local residents earn their living from fishponds. However, these industries have become increasingly vulnerable to flooding caused by coastal erosion and subsidence, rising sea levels, and a lack of coastal barriers. 

These problems are directly impacting lives and livelihoods. For local fishpond farmers like Sururi, solutions are sorely needed. Back in 1995, he started planting mangroves around the village, creating a natural greenbelt that also acts as a flood barrier.

Starting from Scratch: Building Nature-based Solutions 

When Sururi began planting mangroves almost three decades ago, the area was a coastal sea. “In the past we had no natural barriers. The shoreline was directly exposed to the sea, causing coastal erosion because the shoreline was hit with the waves again and again,” he remembers. “But after we started planting mangroves, they held soil and sands behind the mangroves and slowed down the erosion.” Pointing to the thriving mangrove forest behind him, he explains that, as the mangroves grow bigger, they encourage the land held behind the mangroves to collect and form a natural defense against coastal erosion that triggers tidal floods. 

During the past 29 years, Sururi has seen his fair share of difficulties. The first two years were the hardest,” he explains. Finding seedlings was very difficult, and I had no one to teach me,” he says. In 1997, this changed when Sururi met a professor who mentored him on the proper way to plant mangroves

Recognition for Reforestation: Sururi Receives a Prestigious Kalpataru Award 

Sururi’s efforts have not gone unnoticed. In May 2024, he was awarded the prestigious Kalpataru Award by the Ministry of Environment and Forestry. “I’m grateful, after nearly 30 years of effort, we have achieved the Kalpataru Award. It motivates us to preserve the coastal area better,” he says. 

But despite the personal accolade, Sururi maintains he could not have achieved anything by working alone; for replanting activities to really take root, it takes a village. Having worked together to make it happen, the communities are also enjoying the dividends of this collective endeavor, as the return to ecosystem health has impacted positively on the local economy.  

“Now, local communities can reap the benefit,” says Sururi. “There is a green mussel nursery here, providing an additional source of income for fishermen.”

Trees4Trees Support for Mangrove Restoration in Mangunharjo  

While the mangroves in Mangunharjo have certainly helped prevent a repeat of recent disasters, the area needs more trees to sure up its defenses. To support these efforts, Trees4Trees teamed up with 90 local volunteers, including Sururi and his Mangrove Lestari Farmer Group, to plant 2,000 new mangrove seedlings and 100 Australian pine trees over an area covering 1200 square meters. The activities formed part of the Trees4Trees Planting Festival, held on June 11, 2024.

For Sururi, the benefits of these activities are clear: “Biodiversity has flourished, including shrimp and fish. Birds are more abundant in the evenings now too. In the past, we needed the military to protect this area, but now the thriving habitat safeguards itself.”  

Sururi sends his thanks to Trees4Trees, along with hopes for the future:. “We hope this initiative will continue and expand to other locations as well.”

5 Facts About Mangrove You Need to Know

mangrove roots store vast amount of carbon

mangrove roots store vast amount of carbon

Mangrove forests are among the most important ecosystems on Earth. They are crucial for protecting life on Earth. Alongside salt marshes and seagrass beds, mangroves are part of the “big three” coastal ecosystem that is incredibly powerful at saving the planet. With their dense coverage, mangroves act as natural coastal barriers, protecting communities and serving as nursery grounds for biodiversity.  

Their remarkable ability to sequester vast amounts of carbon helps stabilize the planet’s temperature. It makes them as key weapons in the fight against climate change and preventing global warming from worsening. However, global mangroves populations have been threatened by overexploitation and coastal development, leading to significant losses in recent decades.  

Here are some fascinating facts about mangroves and their spectacular ability! These facts are also highlighting the importance of why we should pay more attention to protecting them from damage and disappearance.  

Mangrove forests store greater carbon than terrestrial forests 

Mangroves cover only 0.1 percent of the planet’s surface. However, latest studies suggest that mangrove forests can sequester carbon 10 times greater than mature tropical forests annually. Scientists also estimate that mangroves store an average of three to five times more carbon than tropical forests in the same size of area. Most of the carbon is stored in the sediment beneath the trees. It can remain bound there for decades, centuries, or even millennia. 

However, when these habitats are destroyed, they will lose their capacity in sequestering carbon. Additionally, they will also release a huge amount of carbon, increasing greenhouse gas levels in the atmosphere.

Mangroves flourish in the Semarang coastal area, helping the community in preventing tidal floods and erosion.

Coastal defense against floods and tidal waves  

Mangroves have a strong and intricate root system which helps to bind the soil and prevent coastal erosion. These roots also intertwine to form a dense brush above the water that can break waves and absorb wave energy. It is including the hurricane-generated waves or tsunamis.  

Mangrove forests reduce the impact of tidal waves and floods by decreasing the height and velocity of incoming waves. They distribute water among the creeks and canals within the mangroves. This way will reduce the inundation level and the power of waves striking residential areas, farms, or ponds owned by coastal communities. 

A study found that during the deadly 2004 Indian Ocean tsunami, areas with coastal forests, including mangroves, suffered less damage.

In collaborating with local communities, Trees4Trees plants mangroves in Pati, Semarang, and Cilacap coastal areas.

Incredibly adaptable to the harsh condition and can grow in salty water 

Mangroves are naturally adapted to thrive in coastal zones and harsh coastal conditions. They are highly salt-tolerant, able to survive in water up to 100 times saltier than most plants. Mangroves can filter out up to 90% of the salt in seawater. Furthermore, some species have leaves that excrete excess salt. 

Some mangroves have special roots called pneumatophores that extend above the water to absorb oxygen. These roots, with tiny openings take the oxygen in. However, these parts can easily get clogged by pollutants like oil, be damaged by parasites, or be affected by prolonged flooding. Over time, these environmental stresses can kill large areas of mangrove forests. 

5 Facts About Mangrove
The mangrove root systems make the mangroves can tolerate salty water and harsh coastal condition.

Mangrove ecosystems are among the most biologically diverse on Earth 

It is estimated that there are about 80 mangrove species, making this ecosystem highly diverse. Mangroves thrive in tropical and subtropical latitudes. They range in height from small shrubs to 40-meter-tall trees above the water. Despite their differences, all mangroves grow in low-oxygen, high-salinity coastal environments. Each species has its own unique characteristics suited to its native ecological habitat. Therefore, planting the wrong type in the wrong place will prevent the mangrove from surviving.

5 Facts About Mangrove

Indonesia boasts the largest mangrove cover in the world 

Indonesia, where Trees4Trees focuses its reforestation efforts, boasts the world’s largest mangrove population. The country accounts for 23% of the global mangrove coverage, with 3 million hectares of mangroves. As the comparation, the size is over 40 times the size of Singapore. Indonesia is home to approximately 45 of the world’s 75 true mangrove species. Some of them are growing as tall as 50 meters. 

However, Indonesia also experiences the highest rate of mangrove destruction globally. From the 1970s to 2007, the FAO reported that around 40% of Indonesia’s mangrove forests were lost. Residential development, agriculture, and aquaculture are the most factors that caused the degradation.

All My Efforts Were Worth It: Planting Mangroves, Protecting Livelihoods in Pati

All My Effort

All My Efforts Were Worth It: Planting Mangroves, Protecting Livelihoods in Pati

As the fifth of eleven siblings, Parmi missed out on a formal education in his youth. Instead, he and his two older brothers learned how to manage fishponds from their father. Parmi quickly turned this passion into a profession and now, more than 50 years later, continues to make a living in this way. 

Fishponds at the center of community life 

Central Java’s Pati Regency, where Parmi lives, is well known for its milkfish (ikan bandeng). “I manage two fishponds covering a total of 1.25 hectares,” he explains. “During the harvesting season, I can yield around a ton of milkfish per hectare, and we harvest two or three times a year.”  

With the income he makes from fishponds, Parmi can provide for his family. “This work allows me to give my son and daughter the education opportunities I never had,” he says.

Planting trees for protection 

Parmi’s fishponds are located in the coastal village of Dukuhseti, around 100 meters from the shoreline. In 2001, huge waves flooded the coast, destroying ponds and causing enormous damage. “I lost hundreds of millions of rupiahs,” he recalls. At that time, there were no protective barriers along the coast, leaving fishponds vulnerable to floods.  

In response, Parmi and his fellow fishpond farmers took steps to ensure this disaster would not happen again. They planted mangroves along the shoreline to provide a natural buffer against the waves. Now, 23 years later, those mangroves have grown big and strong. But there are not enough of them to guarantee protection. 

In 2022, there was another huge ocean surge. “I lost around 100 million rupiahs (USD 6,190),” Parmi remembers. But he was relatively unscathed, compared to other farmers further up the coast. “Our neighboring village suffered even greater losses because they didn’t have as many mangroves protecting their coast,” he explains. 

All My Efforts Were Worth It: Planting Mangroves
(above) Parmi plants new mangroves with members of the Trees4Trees team

Grab and EcoMatcher team up to plant mangroves 

Back in 2021, Parmi and other members of the Tani Makmur Mandiri farmers’ group were invited to join a mangrove planting initiative run by Trees4Trees, EcoMatcher, and Grab. A total of 30,000 mangrove trees were planted, creating a green belt covering 3.8 hectares along the Dukuhseti shoreline. 

Now, three years later, Parmi and his fellow farmers are reaping the rewards of their efforts. “Planting mangroves is not easy,” he says, remembering how he and his team would work waist-deep in muddy ground. “But seeing these trees grow big and strong (almost all of them are now at least three meters tall), I feel all my efforts were worth it.”  

Ocean waves no longer threaten Parmi’s fishponds as they once did. And the flourishing mangroves offer a range of other, unexpected benefits to the community – the leaves provide a sustainable source of organic fertilizer for the fishponds and the fruits, known locally as brayuh or brayo, can be sold at markets. 

“Local people often come to pick the fruits,” explains Parmi, “which they can sell for 5,000 Rupiah (about thirty US cents) per bucket (500 grams). These fruits are highly in demand here, given their importance to local dishes.”  

Mangrove fruits

Parmi has seen first-hand the protective power and economic potential of mangroves in his community. He insists that caring for these trees and using them sustainably is essential to environmental health and social well-being. “Everyone in the village can freely pick the fruits or leaves, but cutting them down is strictly prohibited,” he says.  

“We would like to thank Grab, Trees4Trees, and EcoMatcher for providing us with these mangroves and the many benefits they offer,” says Parmi.We will continue working to protect and appreciate these mangroves, just as they protect our homes and safeguard our livelihoods.

Located close to Segara Anakan lagoon in Java’s Cilacap Regency, Ujung Alang Village was once covered in mangroves. In the 1990s, the region experienced massive deforestation, mostly because of land being converted for aquaculture ponds. 

In the last two decades, local residents have been helping the mangroves bounce back. A conservation area has been set up and has since become a hub for studies and research into the natural world.  

Now, with support from Trees4Trees, mangrove restoration in Cilacap is going up a gear. An ambitious new replanting project has provided the investment and manpower needed to give the ecosystem a new lease of life. 

Healing the wounds of the past 

Before 1994, Ujung Alang and was covered with mangrove forests. These trees were then cleared by investors to make way for shrimp and milkfish ponds. This venture lasted just four years; by 1998, the ponds had been abandoned.,  

Virtually overnight, the investors cut their losses and left town. But not before leaving their mark on the landscape. Thousands of hectares of mangrove forests had been cut down and turned into barren land.  

In 2000, local communities decided to act, and made a plan to restore the mangroves to their former state.

Working together to restore mangroves 

Over the past decade, local communities, with the support of the government and various other supporters, have successfully planted 56 different species of mangroves in an area covering approximately 400 hectares. Trees4Trees has committed to supporting these ongoing efforts. 

In early 2023, working in collaboration with the Tani Krida Wana Lestari farmer group, Trees4Trees began replanting an area of 2.4 hectares around Ujung Alang. So far, we have planted more than 7,600 trees together.

“Deforestation of mangrove forests in Segara Anakan has led to a significant reduction in mangrove area and caused a decline in fish catches,” explains Armin Agung Mubarok, the Trees4Trees Impact Officer and coordinator of the mangrove project. “By restoring the mangrove ecosystem, we aims to restore the habitat as a nursery ground for crustaceans and other animals, thereby enhancing biodiversity in the region,” he added. 

Haryadi is the Trees4Trees GIS officer on the project., He experienced a number of challenges in clearing away the old growth to make way for new mangroves. As he explains, “clearing the areas of weeds is crucial, as they hinder the growth of the mangroves.”

Restoring natural balance to the ecosystem  

After the weeds had been cleared, Trees4Trees focused on planting four different mangrove tree species, each one chosen to match the unique conditions of their environment.  

In areas less affected by the tide, large-leafed orange mangroves (Bruguiera gymnorrhiza) were chosen, due to their ability to thrive in areas where there’s not much saltwater. They can also do well in both shady and sun-baked areas. 

In tidal areas that are regularly flooded, tall-stilt mangroves (Rhizophora apiculate) were planted, as they thrive in wet, muddy soil. Red mangroves (Rhizophora mucronata) were chosen for inundated areas, where they can grow and thrive. 

Finally, seedlings of spotted mangroves (Rhizophora stylosa) were planted throughout the area, to improve the diversity of species.

Next steps: Taking replanting to the next level 

This small-scale pilot project, was an opportunity to test out planting methods before launching a more ambitious program. Over the next five years, Trees4Trees intends to scale up these efforts and continue planting mangroves to restore mangrove cover.  

“Based on the trial we conducted, we were able to plant 3,500 trees per hectare,” says Haryadi, who is working to turn initial impact into long-term reforestation. “Over the next few years, our goal is to plant mangroves over an area of 1,000 hectares.
