Makira Natural Park: A Comprehensive Geographic Overview of Madagascar Largest Humid Forest Protected Landscape

The origins of Makira Natural Park lie in a 2001 initiative by the Malagasy Ministry of Environment and Forests, working in partnership with the Wildlife Conservation Society, which began a programme to identify and protect one of the last major blocks of humid forest in northeastern Madagascar. The Makira forests were recognised early on as a priority for conservation because they combined exceptional biodiversity, large forest cover, and the presence of multiple critically endangered primate species.

In December 2005, the area received temporary legal protection, which provided an initial legal framework for management and allowed the establishment of early conservation activities on the ground. This interim status supported several years of biodiversity surveys, community engagement, and the development of a forest carbon project, while formal gazettement was still being prepared.

The park was formally created on 19 June 2012 by Decree No. 2012-641, marking the culmination of more than a decade of planning, research, and negotiation among national authorities, conservation organisations, and local communities. Since gazettement, the protected area has been managed under a delegated management arrangement, and community-based forest management through the Gestion Contractualisée des Forêts process has become an integral part of its governance structure.

Makira Natural Park lies in one of the most rugged and forested regions of northeastern Madagascar, set inland from Antongil Bay and forming part of the broader Masoala-Makira-Antongil Bay landscape. Its terrain is characterised by steep ridges, short elevational gradients, and a complex network of valleys carved by rivers descending toward the Bay of Antongil. Elevation changes are relatively modest but abrupt, producing a patchwork of microhabitats within short horizontal distances.

The geological substrate of the park is unusually varied for a humid forest reserve. Granitic, metamorphic, ultramafic, and alluvial substrates are all represented, and soils derived from these different rock types support distinct forest communities. Ultramafic substrates in particular are associated with specialised plant associations and are a focus of botanical interest. The combination of diverse geology and dissected topography contributes significantly to the park's exceptional floristic richness and to its high levels of plant endemism.

The climate reinforces the lush character of the landscape. Makira lies in one of the wettest parts of Madagascar, with mean annual rainfall exceeding 3,500 mm and sometimes approaching 5,900 mm, distributed throughout the year without a pronounced dry season. Humidity remains around 85 percent year-round, and even the driest months receive substantial rainfall. Persistent moisture, fog, and cloud cover sustain the evergreen canopy that defines the park's appearance and underpin its function as a refuge for moisture-dependent rainforest species.

The forests of Makira belong to Madagascar's eastern humid forest biome and represent one of the largest remaining contiguous blocks of low and mid altitude evergreen rainforest in the country. Continuous canopy cover, minimal fragmentation at the core, and an exceptionally wet climate define the park's ecological character. Native tree families characteristic of the area include Sarcolaenaceae, Sapotaceae, Clusiaceae, Ebenaceae, Burseraceae, Phyllanthaceae, Anacardiaceae, and Pandanaceae, alongside prominent populations of native palms, including many Dypsis species, the iconic traveler's tree (Ravenala madagascariensis), and the raffia palm (Raphia farinifera), which is locally important for fibre and other uses.

Palm diversity is one of the defining ecological features of Makira, reflecting the broader importance of the MaMaBay landscape as a centre of palm endemism. Botanical inventories conducted in and around the park, combined with historical herbarium records, indicate that the flora is broadly representative of the eastern humid forest biome while also including a high proportion of locally endemic taxa. Researchers from institutions including the Missouri Botanical Garden and partner Malagasy organisations have highlighted Makira as a priority area for plant conservation.

The park also plays a significant role in regulating ecosystem services at the landscape scale. Watershed protection within Makira limits sediment delivery into Antongil Bay, helping to maintain downstream fisheries and coastal habitats. The intact forest cover contributes to climate regulation, freshwater provision, flood regulation, and coastal protection, linking the ecological integrity of the park with the well-being of communities both inside the buffer zone and along the coast.

Makira Natural Park is biologically best known for its lemur community, which is the most species-rich recorded in any Malagasy protected area. Seventeen lemur species have been documented in the park, spanning a cross-section of Madagascar's primate diversity. Three of these species, the silky sifaka, the indri, and a subspecies of black-and-white ruffed lemur, are classified as Critically Endangered, while the red ruffed lemur is notable because its entire global range is restricted to the Makira-Masoala region north of the Antainambalana River.

The silky sifaka is the park's most iconic species. One of the rarest primates in the world, it is largely confined to the Marojejy-Makira-Masoala landscape, and within Makira its southern distributional limit corresponds to the Antainambalana River. The park also supports the aye-aye and several other lemurs of conservation concern, providing important refugia in a country where primate habitats have been severely reduced.

Beyond primates, the park harbours more than 50 mammal species, including the fossa, Madagascar's largest endemic carnivore and a Vulnerable species on the IUCN Red List, the falanouc, and 13 species of tenrecs. Endemic rodents in the family Nesomyidae, including species of Eliurus and Nesomys, also occur. Birdlife is equally notable: more than 120 species have been recorded, with a strong representation of endemic taxa, including around ten species of vangas and high densities of Bernier's vanga, as well as threatened species such as the Madagascar serpent eagle and the Madagascar red owl. Reptile and amphibian communities include multiple endemic chameleons in the genera Brookesia, Calumma, and Furcifer, the spectacular leaf-tailed geckos of the genus Uroplatus, endemic Malagasy boas, and a rich assemblage of frogs in the genera Boophis, Mantidactylus, Gephyromantis, Mantella, Stumpffia, and Plethodontohyla.

Makira Natural Park is internationally recognised as a site of global conservation significance, layered under multiple biodiversity prioritisation frameworks. It lies within the Madagascar and Indian Ocean Islands Biodiversity Hotspot, is recognised as a Key Biodiversity Area under the global KBA standard, falls within BirdLife International's Endemic Bird Area for East Malagasy wet forests, and has been identified as an Alliance for Zero Extinction site, with the silky sifaka and red ruffed lemur as trigger species. It is also part of WWF's Global 200 ecoregion framework and is included in Madagascar's network of Important Plant Areas.

The park meets all three biodiversity-related High Conservation Value categories defined under the HCV framework: significant concentrations of biodiversity values, landscape-level ecosystems supporting viable populations of species in natural patterns, and threatened or rare ecosystems. Hundreds of species occurring in the project zone are listed as Vulnerable, Endangered, or Critically Endangered on the IUCN Red List, with additional species listed under CITES appendices.

Beyond biodiversity, Makira is notable for being the location of one of the world's first REDD+ projects, a programme launched in January 2005 that aims to reduce emissions from deforestation and forest degradation. In 2013, the Makira Natural Park REDD+ Project became the first government-owned REDD+ project in Africa to sell verified carbon credits on the voluntary carbon market, achieving verification under the Verified Carbon Standard and the Climate, Community and Biodiversity Standards with triple Gold designation. A portion of carbon revenues is returned to surrounding communities to support infrastructure, education, health, sustainable agriculture, and alternative livelihoods, embedding the park within a broader climate and rural development agenda.

The human landscape around Makira Natural Park is shaped by the Betsimimaraka and Tsimihety peoples, two of the major ethnic groups of northeastern Madagascar, whose ancestors have long inhabited the forested hills and valleys of the MaMaBay region. Most residents are agriculturalists, cultivating subsistence crops such as rice and cassava alongside cash crops including vanilla, cloves, and cocoa. Raffia, harvested from the abundant raffia palms in the park's buffer zone, is another important source of income and material culture.

Roughly 90,000 people live in around 120 villages within or adjacent to the park's project area. Their relationship with the forest is intimate and multidimensional: hunting and gathering, wild honey collection, the use of botanical ethnomedicines, and even the consumption of certain clay and riparian earths (geophagia) form part of everyday life. Studies have shown that household diets depend in part on wild protein, and reducing reliance on bushmeat through improved agriculture, small livestock, and fisheries is one of the principal strategies used to align conservation goals with local food security.

Cultural identity in the Makira region blends traditional Malagasy religion with Christianity. Zanahary, the supreme being in Malagasy cosmology, is widely venerated, and even among the Christian population, a large majority continue to practise elements of traditional religion. This syncretic cultural context is reflected in how communities relate to the forest, treating it not only as a resource base but also as a landscape of ecological and spiritual significance.

Community-based forest management is central to the park's social architecture. More than 80 Communautés de Base have signed Gestion Contractualisée des Forêts contracts with the Government of Madagascar, transferring day-to-day management of more than 350,000 hectares of buffer forest to local associations. These COBAs administer agroforestry initiatives, value-chain support for non-timber forest products, and participatory ecological monitoring, making local communities central actors in the park's conservation model rather than simply beneficiaries or bystanders.

Makira Natural Park stands out as Madagascar's largest contiguous block of low and mid altitude humid forest under formal protection, and as the protected area with the highest documented lemur diversity in the country, including 17 species, three of them Critically Endangered. The silky sifaka, one of the rarest primates on Earth, finds one of its last strongholds here.

The park's profile is further defined by its exceptional palm diversity, its rich endemic bird fauna within BirdLife Endemic Bird Area 094, and its recognition as an Alliance for Zero Extinction site. Its ecosystem-service role is also significant: protection of the Makira watershed reduces sediment delivery into Antongil Bay, supporting coastal fisheries and downstream water quality.

Makira is unusually important in conservation policy as well. It hosted one of the world's first REDD+ projects and became the first government-owned REDD+ project in Africa to sell verified carbon credits, with community-based forest management at the heart of the model. The combination of high biodiversity value, pioneering forest carbon finance, and deep community involvement makes Makira a benchmark for integrated tropical conservation.

Because Makira lies in one of the wettest parts of Madagascar and has no marked dry season, the park is technically accessible throughout the year, though conditions vary. Rainfall is heaviest in the main rainy months, when trails can become muddy and rivers harder to cross, while drier months tend to bring somewhat more comfortable hiking conditions and better visibility for primate and bird watching.

The relative dryness of the September-October period corresponds to a modest pause in the otherwise continuous rainfall pattern, and this window is often associated with more reliable access to forest trails and a slightly higher likelihood of lemur sightings, including the silky sifaka, whose white fur stands out against the green canopy. For visitors interested in birdwatching, the same months can be rewarding because reduced rainfall can make forest birding easier. For visitors prioritising landscape scenery and the most luxuriant forest display, the wetter months offer a more dramatic and lush experience, with mist-shrouded ridges, swollen rivers, and a fully active forest.
