Mount Ntringui

Mount Ntringui National Park protects the highest peak on Anjouan Island, rising to 1,595 meters at the summit of Mount Ntringui. The park preserves the last significant remnants of montane rainforest on Anjouan, an island that has lost over 80% of its original forest cover. These remaining forests harbor several critically endangered endemic species found nowhere else on Earth. The park represents a critical conservation intervention on one of the most densely populated and deforested islands in the Indian Ocean, where pressure on remaining natural habitats is intense.

The park's forests are the last refuge for the critically endangered Livingstone's fruit bat (Pteropus livingstonii), the world's rarest fruit bat, with the majority of its approximately 1,200 individuals roosting in Mount Ntringui's remaining tall forest. Endemic birds include the Anjouan scops owl (Otus capnodes), Anjouan sunbird, and Comoros blue vanga. The forests support several endemic reptiles including the Anjouan day gecko. Chameleons of the genus Furcifer inhabit the canopy. The introduced brown lemur (Eulemur fulvus), brought from Madagascar centuries ago, maintains a small naturalized population. Invertebrate diversity is high but poorly documented, with numerous endemic snails and insects likely present.

Mount Ntringui's summit forests represent the most intact humid forest remaining on Anjouan, though even these are significantly degraded compared to historical extent. The canopy reaches 15-25 meters with emergent trees including Weinmannia comorensis and Tambourissa species. Epiphytic orchids, ferns, and mosses festoon the branches in the cloud-shrouded upper zone. Tree ferns (Cyathea) dominate understory gaps. Below the intact forest, a transitional zone of degraded secondary growth and agricultural encroachment creates an abrupt forest edge. The summit area supports dwarf scrub with endemic heath species. Many plant species remain undescribed by science, and botanical surveys continue to discover new records.

Mount Ntringui is the eroded core of Anjouan's ancient volcanic edifice. Anjouan formed approximately 3.9 million years ago and is the oldest island in the Comoros volcanic chain. Extensive erosion has carved deep valleys radiating from the central peak, creating the island's characteristic rugged topography. The summit rocks are heavily weathered basalts and phonolites. Deep lateritic soils on the slopes support dense vegetation where intact. Numerous streams originate from the summit zone, providing the island's primary freshwater supply. Landslides on deforested slopes expose red laterite subsoils. The contrast between intact forested slopes and eroded cleared land demonstrates the critical role of forest in slope stability.

Mount Ntringui's summit zone is among the wettest locations in the Comoros, receiving over 4,000 millimeters of annual rainfall. Persistent cloud cover envelops the upper mountain from approximately 800 meters, creating the misty conditions that sustain the cloud forest ecosystem. Summit temperatures range from 12-20 degrees Celsius, considerably cooler than the coastal lowlands. The wet season from November to April brings intensified rainfall and occasional cyclone damage to exposed canopy. The drier period from June to September reduces cloud frequency somewhat but the summit remains humid. Strong winds during the southeast monsoon can cause branch breakage in exposed canopy trees.

Anjouan has been settled since at least the 6th century by Bantu and Arab-Swahili populations. The island became one of the most densely populated in the Indian Ocean, creating enormous pressure on forest resources. Traditional agriculture on Anjouan involves ylang-ylang distillation, clove cultivation, and subsistence farming on steep hillsides cleared from forest. French colonial plantation agriculture from the 1880s accelerated deforestation at lower elevations. Post-independence population growth pushed cultivation onto increasingly steep and marginal slopes. Charcoal production for cooking fuel remains a primary driver of ongoing forest loss. The remaining summit forests survived primarily due to their steep, inaccessible terrain.

Mount Ntringui was identified as a critical conservation priority through Livingstone's fruit bat surveys in the 1990s that revealed alarming population declines linked to habitat loss. The Durrell Wildlife Conservation Trust established research and conservation programs focused on the bat and its forest habitat. National park status was formalized in 2020 as part of the Comoros national parks system. Prior to formal designation, community reforestation initiatives and conservation education programs laid groundwork for acceptance. The park faces the challenge of protecting forest fragments surrounded by densely populated agricultural land, requiring innovative approaches to reduce forest edge pressure.

The summit trek to Mount Ntringui passes through agricultural zones into remnant forest, offering encounters with endemic wildlife including Livingstone's fruit bats at known roost sites. The hike typically requires 4-6 hours round trip from the nearest village access point. Birdwatching for the rare Anjouan scops owl is best conducted at dusk in forest patches. Viewpoints along the trail provide panoramic vistas across Anjouan's deeply dissected landscape to the ocean. Botanical interest centers on the diversity of orchids, ferns, and mosses in the cloud forest zone. Waterfall pools in stream valleys offer refreshing stops. The dramatic contrast between lush forest and surrounding deforested slopes powerfully illustrates conservation imperatives.

Anjouan is reached by domestic flights from Moroni to Ouani Airport (20 minutes) or by inter-island ferry. The main town Mutsamudu serves as the base for park visits. Local guides from surrounding villages provide essential route-finding and wildlife spotting expertise. No formal visitor facilities exist within the park. Basic accommodation is available in Mutsamudu and surrounding villages. The terrain is steep and trails are often muddy, requiring sturdy footwear. The best conditions for hiking occur during the drier months of June to September, though the summit remains wet. Visitors should be prepared for rapid weather changes and carry rain protection. Community guide fees support local conservation initiatives.

The park's core challenge is halting ongoing deforestation on one of the world's most densely populated islands where 90% of households depend on wood fuel. Reforestation programs using fast-growing native and non-invasive species aim to create buffer zones around remaining intact forest. The Durrell Wildlife Conservation Trust maintains captive breeding colonies of Livingstone's fruit bat as insurance against wild population collapse. Agroforestry programs promote shade-grown crops that maintain partial canopy cover. Community nurseries produce native tree seedlings for restoration. Water supply protection provides an economic argument for forest conservation, as deforestation causes stream flow reduction. International donor support remains essential given limited national conservation budgets.
