At dawn, a powerful and haunting call echoes through the humid forests of eastern Madagascar. This unmistakable sound belongs to the Indri Indri, the largest living lemur and a true symbol of the Andasibe forest. More than a fascinating animal, the Indri is a strong emblem of Madagascar’s biodiversity and a key indicator of forest ecosystem health.
The Indri Indri, a unique lemur species
The largest living lemur
The Indri Indri is instantly recognisable by its impressive size, reaching nearly one metre in height, and its distinctive black-and-white fur. Unlike many other lemurs, it has no tail, making it truly unique among primates.
Fascinating behaviour
Strictly arboreal, the Indri moves through the forest in spectacular vertical leaps from trunk to trunk. It lives in small, close-knit family groups, with strong social bonds and complex communication.
An iconic forest call
Indri’s song can be heard several kilometres away. Used to mark territory and strengthen group cohesion, this morning call is one of the most iconic sounds of the Andasibe forest.
-> Indri indri : the Soul of Endrigna Ecovillage
The Indri Indri is inseparable from its natural habitat. In Madagascar, it is in the Andasibe-Ampangalatsary region that one of the most favourable environments for its survival can be found. This forested area, located in the east of the country, plays a key role in the conservation of Madagascar’s biodiversity.
Andasibe: a vital natural habitat for the Indri Indri
The humid forests of Andasibe-Ampangalatsary
The Andasibe-Ampangalatsary region provides an ideal environment for the Indri: dense, humid forests rich in biodiversity. These primary and secondary forests represent one of the species’ last strongholds.
A diet entirely dependent on the forest
The Indri feeds mainly on young leaves, buds and specific forest fruits. This highly specialised diet makes the species extremely dependent on intact and continuous forest cover.
A key indicator of ecosystem health
The presence of the Indri Indri is widely considered a positive indicator of ecological balance. When forests are degraded or fragmented, the Indri is often among the first species to be affected.
The survival of the Indri Indri is closely linked to the state of the forests in Andasibe. When these ecosystems degrade or become fragmented, the entire Indri population is weakened.
Why is Indri Indri under threat ?
Deforestation around Andasibe
The greatest threat facing the Indri is habitat loss, caused by deforestation, slash-and-burn agriculture and unsustainable use of forest resources.
A slow and fragile reproductive cycle
The Indri reproduces slowly: females usually give birth to a single infant every two to three years. This low reproductive rate makes the species particularly vulnerable.
Limited protection outside protected areas
Although the Indri lives within protected zones, it remains exposed to human pressure in surrounding forest fragments and buffer areas.
Although the Indri Indri is now vulnerable, its situation also makes it one of the strongest symbols of conservation in Andasibe. Its protection now goes beyond the survival of a single species.
The Indri Indri as a symbol of conservation in Andasibe
A powerful emblem for awareness
In Andasibe, the Indri has become a flagship species for forest conservation, helping raise awareness among visitors, local communities and decision-makers.
A strong cultural connection
Local traditions and beliefs (known as fady) often protect the Indri, reinforcing its conservation through cultural respect and ancestral knowledge.
The role of community-based projects
Community-led reforestation initiatives around Andasibe help restore forest corridors that are essential for the long-term survival of the Indri Indri.
Protecting the Indri Indri means protecting the Andasibe forest
Restoring forests to preserve biodiversity
Replanting native species and restoring degraded land helps recreate viable habitats for the Indri and many other endemic species.
Promoting sustainable tourism
Responsible tourism in Andasibe plays a crucial role by valuing wildlife without disturbing it, while providing alternative income for local communities.

Acting together for the future
Protecting the Indri Indri means preserving a fragile balance between humans and nature. Every action for reforestation, education and support for local initiatives contributes to safeguarding the future of the Andasibe forest.
Endrigna Ecovillage’s actions for the protection of Andasibe’s biodiversity
In Andasibe, the ecological richness is exceptional but fragile. Endrigna Ecovillage plays a central role in preserving this unique biodiversity by combining reforestation, awareness-raising, responsible tourism, and local community involvement. For a green and sustainable future, Endrigna Ecovillage is moving forward on a new journey.
Restoring Degraded Forests
Endrigna Ecovillage runs community reforestation programmes, planting native species suited to the Andasibe forest. The aim is to recreate forest corridors to allow species such as the Indri Indri to move freely and reproduce.
Sustainable Monitoring and Maintenance
Each planting is monitored by local teams and volunteers. Endrigna ensures that young trees are watered, protected, and integrated into the local ecosystem, thus guaranteeing sustainable and effective restoration. This approach also strengthens commitment, monitoring and solidarity.
Local Community Training
Endrigna organises workshops for local residents and schools to raise awareness about ecological issues and the protection of endemic species.

Protection of the Indri Indri and other species
Endrigna Ecovillage works to protect the key habitats of lemurs, birds, and endemic reptiles. Specific zones are dedicated to the survival of these species and are subject to regular scientific monitoring. Meet one of our forest defenders.
Educational immersion for visitors
Endrigna welcomes visitors in a nature-friendly environment, offering guided walks and educational workshops on biodiversity. This approach highlights the value of the Andasibe forest while generating revenue for conservation.

Conclusion
The Indri Indri is not only an iconic lemur; it is the living voice of the Andasibe forest. Its survival depends on the preservation of its habitat and collective commitment to sustainable forest management. By protecting the Indri, we choose to protect the unique natural heritage of Andasibe for future generations.
