The Montagne des Français Reserve (French for: mountain of the French) is a protected area consisting principally of dry deciduous forest in northern Madagascar. It is part of the larger Ramena protected area complex which also includes Orangea Reserve and the Ambodivahibe Marine Reserve. These three protected areas are currently being created and will be designated in 2008.

The Montagne des Français reserve protects deciduous dry forest characteristic of the north of Madagascar. Much of the forest is on a calcareous massif that has been eroded into karst formations known locally as Antsingy. The forested area ranges from 100–450 metres above sea level. This mountain is thought to receive more rain than the surrounding area (Antsiranana receives approximately 1000mm precipitation annually) which explains the lush vegetation in an otherwise very dry bioclimatic zone. Preliminary botanical and zoological inventories have been done that show these forests are rich in both fauna and flora and include a remarkable number of local and regional endemic species. In particular this is one of the best places to see one of the most beautiful baobabs, Adansonia suarezensis as well as an aloe, Aloe suarezensis, both of which are restricted to this area of northern Madagascar. Other locally endemic plants of interest include a spectacular flame tree, Delonix regia, the extremely rare Diegodendron humbertii that is the only representative of the family Diegodendronaceae and known from only a few dozen individuals, and Baudouina solleyformis, which is used locally as a traditional protection against witchcraft. To date, 242 species from 58 families and 158 genera have been described from the Montagne des Français; the five most important families that account for over 40% of the species are the Rubiaceae, Fabaceae, Malvaceae, Euphorbiaceae and Sapindaceae.

Zoological surveys to date have identified 19 species of amphibian, 52 reptile species, 56 birds and 21 mammals. Of the herpetofauna, eight species are endemic to the Montagne des Français, 28 are regional endemics, 2 are listed as globally threatened in IUCN's 2006 Red List and 14 species are CITES listed.

The main threats to the Montagne des Français are linked to demand for wood-based products from the nearby city of Antsiranana. Logging for timber and charcoal production are the main threats. Unlike most of Madagascar, slash and burn agriculture is not a major threat since most of the remaining forest is on land unsuitable for agriculture.

Several other karst limestone areas are also protected in Madagascar including Tsingy de Bemaraha, Tsingy de Namoroka and the Tsingy d’Ankarana reserve 100 km to the south of Montagne des Français. The current effort to create a new reserve in the Montagne des Francais involves many local organizations and is being headed up by the local regional government with technical support and funding from Conservation International.


The Montagne des Francais can be easily visited from the city of Antsiranana (also known as Diego Suarez). The base of a trail leading to the summit can be reached approximately 12 km by road from Antsiranana; a guide is recommended. The trail to the summit takes approximately 2 hours and several viewpoints along the way and at the summit provide stunning views over the Diego Bay. The remains of several fortifications dating from the French colonial period can still be seen. These fortifications and the whole area around Diego were the scene of fierce fighting during World War II between the Vichy French occupiers and British forces.
