Madagascar was once known as the “green island” for all its lush forest cover but now, it is called the “red island” referring to the colour of the soil that remains after the trees have been cut down. It's a nation with over 200,000 species of plants and animals unique to Madagascar. But due to aggressive deforestation, over 90% of the forests are gone. Due to extreme poverty, many villagers have been forced to cut down entire forests to use as fuel for burning, construction, and agricultural use. tentree has been working to support the Malagasy people revitalize their local forests and maintain them with sustainable practices.

Total Trees Planted

Why Mahabana Region?

One of the poorest countries in the world, Madagascar faces extreme deforestation due to unsustainable practices . 

tentree works closely with Eden Reforestation to replenish the mangrove trees at the Mahabana Estuary, 65 kilometres south of the port city of Mahajanga. Local workers learn valuable skills and develop practices to enable self-sufficiency. These planting projects help promote strong economies and stability, which in turn, supports the community to access healthier food, life essentials. and affordable healthcare. 

The Impact

Carbon Absorption

Mangrove trees can sequester up to 4 times more carbon than any other tree.

Fish Stock

Coastal villages rely heavily on fishing to provide food for their family.

Storm Protection

Extreme weather threatens habitat and communities in the Northwest coast. Mangrove trees are vital in damage control and prevention.

Habitat Revitalization

These forests provide homes for the thousands of endemic species.

The Trees

The majority of the funds provided by tentree and its supporters enable the planting of mangrove trees along the estuary shoreline. 

Red Mangrove

These trees help prevent coastal erosion and are key to restoration of mangrove habitats. The root systems hold the soil together so the nutrients aren’t pulled away when the tide goes down. It is also used for firewood, the construction of buildings, and making fish traps. Various parts of the plant are also used in folk medicine.

Planting Process


Seed Collection

Mangrove are called “Propagules” and are dropped from the branches of mature trees. Once the propagules are collected, they are sorted, counted, and carefully stored for the next planting session.


Clearing Debris

A major part of the planting process in coastal areas is the clearing of debris (dead trees, stumps, branches, etc). This debris not only makes it extremely difficult to maneuver when planting, but also proves to be a great risk to destroying freshly planted propagules. Additionally, some of the removed debris can be used for fuel when cooking.


Transporting Trees

Each sack of propagules can weigh up to 50lbs and have to be transported by canoe. The most difficult element of the transportation is timing the tides within the mangrove channels to ensure the planting crews are able to safely return back to the village.


Planting the Mangroves

Planters must walk through thick, black, waist-high mud to randomly distribute the propagules. The seedlings are carefully pushed into the mud 3-4 inches. A crew of 12 planters will typically plant about 20,000 trees in a planting session.


Project Monitoring

In order to improve the quality of restoration projects, there is a critical need for monitoring the survivability of the work being done. Gathering accurate information from the most remote areas on earth is a difficult task. With our partners at Eden Reforestation Projects, we have been able to implement an offline data collection system that tracks when, where, and who planted the trees using mobile devices and weather-proof backup technology. With this technology we can gather images from the field and data for improving the overall success of a project.
