Anjajavy's Protected Area is an element of the Madagascar dry deciduous forests situated on the Indian Ocean of northwest Madagascar. The Anjajavy Forest surrounds the village of Anjajavy and provides a habitat for many rare species and endangered species.Nick Garbutt, C. Michael Hogan, Hilton Hastings, Wendy Pollecutt, Tahiana Andriaharimalala, Anjajavy, the village and the forest, Lumina Technologies, May 12, 2006 It covers roughly fifty square kilometres, and occupies a continuous portion of the peninsula upon which Anjajavy village lies. The peninsula is bounded by Majajamba Bay to the south and Narinda Bay to the north. Anjajavy Forest has much in common with other dry deciduous forests rising out of the Karst topography limestone formations of western Madagascar. It is due to the presence of expansive tsingy as well as the remoteness of this part of Madagascar from the population center of the country at Antananarivo that the forest here has been less disturbed than many other forests in the country. For example, the central highland plateau, readily accessible from the population center, has been decimated by decades of slash-and-burn farming by indigenous peoples, leading to massive desertification and erosion. The incidence of species endemism in the western dry forests is very high, including ten of the fourteen known lemur genus, five of the eight tenrec genera and 16 of the 17 Chiroptera genera of Madagascar represented. There are a variety of , , and present within the Anjajavy Forest.
Like most of Madagascar's dry deciduous forests, the upper canopy is composed of trees which shed their leaves in the winter months (May through September), including at least two species of Adansonia endemic to the western part of the island. Trees here have adapted to the warm arid climate by deciduous in the dry season to reduce evapotranspiration, and some species such as the Adansonia store large amounts of water in their bulbous trunks.
There is a very high rate of species endemicity in all the western dry deciduous forests of Madagascar, for both flora and fauna; this rate is thought to be higher than for the eastern , although the biodiversity, while extremely high, is slightly less than the eastern counterparts. Geologically the tsingy formations have numerous caverns (used by early tribesmen) and karst formations, which provide aquifer.
Madagascar is a botanical paradise, with more than 13,000 indigenous species including 900 Orchidaceae varieties, 200 Arecaceae species and 130 species of Aloe striata. The island is so large and has such a diversity of habitats and climates that each corner of Madagascar has its own special community of plants. The forest canopy contains numerous species of deciduous trees, including at least two species of baobab, Adansonia rubrostipa and Adansonia madagascariensis. In addition, trees such as Grewia ciclea (Malagasy name, andilambarika) and Terminalia catappa (Malagasy name: antafana) occur. The latter tree provides a favourite food supply to the Coquerel's lemur, with both fruits and leaves being appealing. 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.WWF 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 (vines) as well as numerous herbs, including the Madagascar vanilla ( Vanilla madagascariensis, whose Malagasy name is vahimatso). The dry forest verges on mangrove in the vicinity of several coastal estuaries at the western verge of the Anjajavy Forest, where small streams discharge into the Indian Ocean.
The Anjajavy's Protected area and its surroundings include a geological phenomena of rare beauty: the Karst. This karstic and highly rugged landscape is the dramatic expression of an evolutionary stage of the earth, taking the shape of a "stone forest", with limestone towers and spurs as high as 30 meters, all within the forest and in the middle of the sea. Nature has adapted itself to these labyrinths for millions of years and has formed unique natural shows of caves, grottos, highland areas, gorges and walls of rugged rocks. Due to their inaccessibility and their resistance to fire, the Karst has provided protection for numerous parts of the primary forest.
The Adansonia 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 zebu horns, coins, rum or honey in the hope of receiving protection from the ancestors.
The Moramba Bay, the malagasy Halong Bay, is a diverse karstic land formation where Anjajavy meets the Mozambique Channel. Along the coast, the jagged cliffs of many marine Karst rise close to 30m out of the water.
The Anjajavy Protected area is protected to the north and west by three wide, separate mangroves and their winding tidal channels. These wetland ecosystems are an example of the vital service nature provides to human beings on a global scale. The mangrove 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 biotope 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 are therefore one of the most efficient natural carbon sinks in the world, with rates or carbon sequestration up to 50 times greater than those of tropical forests. The phytoplankton and plankton of the mud constitute the point of origin of food supply chains which provide to the precious fish needed for the second economic source of Anjajavy: the traditional fishing industry.

The Malagasy Fish Eagle ( Haliaeetus vociferoides) called «Ankoay» in Malagasy, is a large bird of prey endemic to the coastal strip North-West of Madagascar. Various estimations place the number of remaining breeding pairs to be between 40 and 150. This bird may therefore be one of the rarest on Earth. We must act fast in order to protect the three to six pairs between Anjajavy's Protected Area and Moramba Bay.
