Description

The Tsingy de Bemaraha, located in the Melaky region of western Madagascar, is a UNESCO World Heritage Site renowned for its extraordinary karstic landscapes, unique biodiversity, and cultural significance. Spanning approximately 157,500 hectares, it comprises the Tsingy de Bemaraha National Park (southern part, 66,600 hectares) and the Strict Nature Reserve (northern part, 85,300 hectares). The name "tsingy," derived from the Malagasy word meaning "where one cannot walk barefoot," aptly describes the razor-sharp limestone pinnacles that dominate the region, creating a surreal "forest of stone."

 

Geological Formation and Landscape

The Tsingy de Bemaraha is a geological marvel formed over millions of years from Middle Jurassic (approximately 200 million years ago) limestone deposits of marine origin, primarily fossilized corals. Erosion by acidic rainwater and groundwater has sculpted a karst landscape characterized by:

Limestone Pinnacles: Sharp, needle-like formations, some reaching 100 meters high, create a labyrinthine "stone forest." These pinnacles result from the dissolution of calcium carbonate, forming vertical and horizontal crevasses, grikes, and caves.
Canyons and Gorges: The Manambolo River, which crosses the park, has carved a spectacular 300-meter-deep canyon, adding to the dramatic topography.
Caves and Underground Rivers: A complex karst hydrology includes underground waterways and caverns, some containing sacred tombs of the Vazimba people.
Plateaus: The 250-km-long Bemaraha Plateau, with elevations from 100 meters in the west to 600 meters in the east, forms the backbone of the landscape.
The interplay of forest green vegetation against the metallic gray limestone creates a visually striking effect, described as a "grandiose, spectacular natural landscape" of universal beauty. Posts on X liken it to a "labyrinth of limestone" or "Forest of Knives," emphasizing its otherworldly appearance.

 

Flora

The Tsingy’s vegetation is classified as western dry forest, one of Madagascar’s most threatened biomes, with over 650 plant species, 85% of which are endemic. Key features include:

Dry Deciduous Forest: Dominated by trees like Dalbergia (rosewood), Commiphora, and Hildegardia, which shed leaves in the dry season (May to November).
Xerophytic Scrub: Succulents, including bottle trees, aloes, and Pachypodium, thrive on exposed limestone.
Sub-humid Forest: Moister conditions in canyons support dense forests with orchids and baobabs.
Savannah and Mangroves: Eastern lowlands and areas near the Manambolo River host grassy savannahs and mangrove swamps.
The isolation of the tsingy formations creates microhabitats, fostering high endemism. For example, dolines (sinkholes) act as refuges for green vegetation in the arid west.

 

Fauna

Tsingy de Bemaraha is a biodiversity hotspot, with 85% of its fauna endemic to Madagascar and 47% locally endemic to the region. Its impenetrable terrain has created "refuges within a refuge," isolating species in small pockets, sometimes as small as a single limestone spike.

Mammals: At least 42 mammal species, 35 endemic to Madagascar.
Lemurs: 11 species, including the endangered Van der Decken’s sifaka (Propithecus deckenii) and the locally endemic Bemaraha woolly lemur (Avahi cleesei). Other species include red-fronted brown lemurs, mouse lemurs, and bamboo lemurs.
Small Mammals: Locally endemic species like the Tsingy tuft-tailed rat (Eliurus antsingy), Grandidier’s shrew tenrec (Microgale grandidieri), and lowland red forest rat (Nesomys lambertoni).
Carnivores: Two species from the endemic Eupleridae family, including the fossa, Madagascar’s largest predator.
Bats: 18 species inhabit caves and rock formations.
Birds: 96 species, 39 endemic to Madagascar. Notable species include the critically endangered Madagascan fish eagle, the vulnerable Malagasy harrier, and the endemic Coquerel’s coua with its striking blue eye patches. The recently described rail Mentocrex beankaensis is known only from the Bemaraha massif.
Reptiles and Amphibians: 63 reptile species (58 endemic to Madagascar, 17 to Bemaraha) and 19 amphibian species, the highest diversity in Madagascar’s dry regions.
Reptiles: The critically endangered Madagascar big-headed turtle (Erymnochelys madagascariensis), the locally endemic Antsingy leaf chameleon (Brookesia perarmata), and vulnerable species like the big-headed gecko and Nicosia’s chameleon.
Amphibians: High endemism, with species adapted to the karst environment.
Invertebrates: New species are frequently discovered, including unique spiders and insects adapted to the harsh terrain.
The park’s isolation has driven speciation, with many species awaiting formal description.

 

Cultural Significance

The Tsingy de Bemaraha holds deep cultural importance for the Sakalava people, who inhabit the region, and the Vazimba, considered Madagascar’s earliest inhabitants.

Sacred Sites: The Manambolo River and its caves contain Vazimba graves, deemed fady (taboo) and revered as spiritual sites.
Sakalava Traditions: The Sakalava, primarily agriculturalists, view the landscape as sacred and integrate conservation with cultural practices.
Historical Context: Evidence suggests human settlements in the area date back 2,500 years, linked to Austronesian migrations from Indonesia.

 

Conservation Status and Challenges

Designated a UNESCO World Heritage Site in 1990, the Tsingy de Bemaraha benefits from strong natural protection due to its impenetrable terrain. Managed by Madagascar National Parks, the site is part of the Andrefana Dry Forests serial property, expanded in 2023 to include additional protected areas.

Conservation Strengths:
The karst landscape limits human encroachment, preserving core areas.
Community engagement and ecotourism revenue support conservation, with entrance fees partly shared with local communities.
Recent discoveries of new species underscore its global ecological value.

Threats:
Localized Pressures: Subsistence hunting, selective logging, livestock grazing, and pasture fires occur at forest edges, though they pose little threat to the core.
Agricultural Encroachment: Draining of peripheral lakes and marshes for rice cultivation affects water flow.
Reptile Trade: Two reptile species are traded locally, requiring monitoring.
Climate Change: Potential shifts in rainfall and temperature could impact water-dependent species.
Access Challenges: Poor road infrastructure (e.g., a 9-hour drive from Morondava on rough tracks) limits tourism but also complicates management.
The IUCN Conservation Outlook (2020) rates the site’s prospects as "good," with threats localized and manageable.

 

Visitor Experience

Accessible only from mid-April to mid-November due to the rainy season, the park is best visited from June to November when the Grand Tsingy is open. Located 180-250 km north of Morondava, reaching Bekopaka (the park’s entry point) requires a 4x4 vehicle, two ferry crossings, and a 14-hour drive from Antananarivo or 6-9 hours from Morondava.
