Anjajavy finds itself amongst the community of the dry deciduous forests of the North-West; an eco-region recognised by the major international organisations of nature conservation as a global critical priority for conservation. For naturalists and amateurs of plants, there is a lot to see: aloes, euphorbias, bottle-creepers, giant vanilla beans growing on the sharp limestone formations of the Tsingy. The endemic ebony and rosewood trees are also plentiful. Much of the flora in the Protected Area has not been identified. New species are regularly being discovered in particular from December to April throughout the rainy season. Some of the common shrubs found in the Anjajavy forest are '' Vepris ampody'' (Malagasy name: ampoly) and '' Rhizorphora mucronata'' (Malagasy name: honkovavy). There are also abundant

is an emblem of Madagascar. The large island is home to seven species of baobabs, of which six are endemic. In Anjajavy, there is three species of baobabs: the Grey (''Adansonia madagascariensis''), the African (''Adansonia digitata'') and the Fony Baobab (''Adansonia rubrostipa)''. The latter, endemic to the eco-region is red and gold in color with patterns looking as if they were hand-painted. The baobab trees clinging to the Tsingy islands in the turquoise waters of Moramba Bay shape one of Madagascar’s most spectacular and magical landscapes. These swollen giants have many outstanding qualities. They are the longest living flowering plants on earth - with some living up to 2,000 years. These trees are true survivors, withstanding terrible droughts and fierce storms, and they can grow on bare rock on sea isles. They can even live and grow wrapped around each other, as if in love. Every baobab has its own shape, its own character, its own story. It is therefore not surprising that these incredible trees are revered by the local people, and that some of them are held as sacred. People make offerings at the base of the baobab, such as

rivers flanking the Anjajavy Forest form excellent natural borders to the Protected Area and convenient transportation routes to visit. The mangroves of Anjajavy comprise a great number of species of trees and shrubs adapted to salty water. One of them, the Jajavy (''Salvador angustifolia'') has given its name to the village. The root entanglement forming stilts or buttresses, the thick mud and the daily tidal action forms an excellent haven, nursery and larder for terrestrial and aquatic fauna. Hundreds of species of fish, shellfish, insects and birds depend on this habitat for food and shelter. In Anjajavy, the mangrove swamps protect the natural Reserve of dry deciduous forest as well as the Marine Reserve. This

simultaneously serves as a curtain of protection against strong and salty winds, a fire-wall, a damp buffer useful to the forest during the dry season and as filter against the turbidity of the coastal waters. The two rivers of mangroves on both sides of the Anjajavy forest constitute excellent natural borders for the Protected Area as well as practical transportation routes which allow for better exploration. In general, the mangroves also provide human beings with vital services; the pneumatophore roots help to stabilise the soft soils and to protect the coast line against erosion and natural catastrophes. On a global scale, these habitats capture carbon in their sediments, where it can remain for centuries. The

Bats

The tsingy caves provide special habitat for the bats of this region, offering cool shelter. Probably the most common member of the chiroptera family locally is the Commerson's leaf-nosed bat (''Hipposideros commersoni''). The cave explorers will also sight Tiavato bats ('' Paremballonura tiavato'') in flight and some hanging from the ceiling on stalactite formations of the limestone cave interiors. A cruise on the mangrove before sunset often shows skies with many Madagascar flying foxes ('' Pteropus rufus'').


Fossa

Also seen in the Anjajavy Forest area is the endangered Fossa (''

''), the largest mammalian carnivore is endemic to the island. Even though it looks similar to a puma, it is actually more closely related to the mongoose and civet. Very comfortable in trees, its long tail helps the animal to balance itself on the branches and its very flexible legs allow it to go down tree trunks head down. The main predator of the lemurs, this mammal is essential to the health of the lemur population as it kills the sick or weakest. Its territory is between 1,300 and 2,600 hectares in size. The Fossa is vulnerable to extinction. As a chicken and cattle hunter, it is seldom welcome around homes.
