The Flora of Different Biotopes in Madagascar

Over 80% of the vegetation in Madagascar is endemic to the island: Madagascar has one of the richest floral species in the world, distributed in various environments or ecosystems, almost unique in the world.

From north to south, from east to west, you will get an overview of the Malagasy vegetation.

One must especially consider the radical difference between the flora of the eastern and western slopes of the island.

The central region has a diverse range of plant species, with a unique mix of endemic and exotic flora.

Madagascar is home to rare species that owe their presence to the presence of high mountains.

There are mountain ranges rising from 2000 to 2800 meters in height, hosting a subalpine flora where we find representatives of the flora of the boreal hemisphere.

What does typical vegetation in Madagascar look like?

The eastern flora covers all areas where the trade winds still arrive laden with moisture.

The western flora covers all areas where this wind arrives dry or with no moisture.

Plant life of the East

The east coast of Madagascar, facing the Indian Ocean, benefits from high levels of rainfall, which is the origin of the vegetation. 6 million hectares of tropical rainforest. It stretches along the entire coast, in a long narrow strip, at low altitude – below 800 meters.

Trees that grow in tight rows can reach heights of up to 30 meters. They are called Evergreens: they retain their leaves and remain green all year round.

Dalbergia, Uacapa, Symphonia… the tallest species form a high canopy, capturing maximum light to leave only a fairly dark area under the foliage. In the lower levels of the forest, we find the famous Pandanus, the palms, and above all many.

Types of Orchids.

Known for its rich fauna and flora, this ecosystem is considered one of the most diverse on Earth: while it only covers 7% of the Earth’s surface, the dense rainforest alone contains 70% of the known species on Earth, 80% of which are endemic.

Madagascar’s dense rainforest is one of the most threatened forests in the world.

Only one third of the primary forest remains. To protect its unique ecosystems and biodiversity, as well as to raise awareness among visitors, numerous protected areas have been established.

In the east of Madagascar, there are many national parks known for their natural richness, with many of them classified as UNESCO World Heritage Sites.

The Ranomafana National Park and of course Masoala are some of the best examples.

On the west coast, the tropical dry forest and mangrove swamps

Madagascar’s tropical dry forest covers 2,580,000 hectares on the west coast of the Red Island, along the coast, rising to about 800 meters above sea level.

Less dense than in the western forests, the trees appear to be much sparser.

From the savannah to the lush rainforest, Madagascar’s diverse landscapes are home to a variety of plant species.

Among them are baobab trees, tamarinds, and palms.

Hidden in the thickets, you may sometimes come across a few turtles.

Like the dense rainforest, this ecosystem is also particularly threatened, falling victim to fires and intensive agriculture.

The Kirindy Mitea National Park is a beautiful example of a dry forest, as is the Tsingy de Bemaraha National Park, famous for its Tsingy “forest”.

Mangroven SarondranoAlong the west coast, you’ll find the mangrove forest, one of the richest in biodiversity. The Earth’s biologically diverse ecosystems cover approximately 300,000 hectares. Mangroves are the most representative species, thanks to a dense root network that extends over the water. This network hosts many aquatic species, providing protection from currents and large predators, and is rich in sediments and algae, making the mangrove a true breeding ground for fish. It is also home to seabirds, reptiles, mollusks, amphibians, and more. Mangrove plants are adapted to a fairly harsh environment but remain sensitive and threatened by cyclones and storms that are becoming more frequent.

In the heart of the highlands: savannah and bush.

The central highlands of Madagascar stretch from north to south and are characterized by a variety of different biotopes. Rice terraces, savannas, and mountains shape the diverse landscapes.

Unlike other Malagasy ecosystems, this area is not considered to have the richest biodiversity, but the landscapes with ochre-colored laterite soils and green rice fields remain spectacular.

At the southern end of the highlands, a bushy area is concentrated: it looks like Australia, yet 80% of the species are found nowhere else.

The unique vegetation of Madagascar is unlike anything else on the planet.

A short forest of bushes and thorny scrub, with main species including Euphorbias, Didiereaceae, and Apocynaceae.

The vegetation, adapted to dry soils, grows as close to the ground as possible, developing means of water storage and conserving water: rhizomes, glossy and waxed leaves… like Aloe and Agaves, with thick leaves and nectar-filled flowers.

The road from Beloha to Ambovombe crosses the territory of the Androy through the bush. From the roadside, you can see prickly pears that the The region is known for its thorny bushes that form a natural barrier. It is also a breeding ground for Zebus and the cultivation of Sisal from Agave trees for ropes and carpets near the cities.

The microclimate of the region varies from dry plains to humid forests. Sambirano stands out for its unique species and location on the western slope, creating a microclimate that supports a mix of tropical and eastern vegetation types.

Sambirano, located in the western territory, shares similar species and forms with the east, showcasing a diverse range of flora.

Madagascar is home to world-famous cocoa varieties that are processed locally or even worldwide into very fine chocolate.

These three regions have imprecise boundaries, and one transitions imperceptibly from one region to another.

Madagascar has the particularity of having a very fertile land where everything grows.

Among all the listed plants on the island, 80 to 90% are endemic species. Due to its isolated location in the middle of the Indian Ocean, Madagascar has seen many plant and animal species thrive.

The degree of endemism is so high that there are no less than twelve

Madagascar is known for its unique biodiversity, with entire plant families that are endemic to the island.

This endemic species diversity is also due to a variety of climate zones: from the driest regions to moisture-saturated regions.
The country’s richness allows you to discover exceptional species such as orchids, baobabs, palms, ravenala, Madagascar jasmine, or succulent plants.
