Site description The site lies 35 km north-west of Toamasina and 4.5 km from Fontsimavo, being situated on a rocky foothill overlooking the coastal plain. It comprises a series of mountainous peaks with steep slopes. Small seasonal tributaries of the Ivoloina river cross the reserve, which is covered by low-altitude, dense, humid evergreen forest, typically with trees of Dalbergia, Ilex, Tambourissa and Canarium, and tree-ferns Cyathea. Screw-pines Pandanus, tree lianas and bamboo-lianas Nastus are abundant. Secondary woodlands and thickets (in degraded areas of forest) cover 30–35% of the site, and are dominated by fast-growing species such as traveller’s palm Ravenala, bushes of Solanum and Lantana, and wild ginger Aframomum.

Key Biodiversity See Box and Tables 2 and 3 for key species. Seventy-seven species are known from the site, of which 51 are endemic to Madagascar. Four of the species are confined mainly to the north-eastern forests of Madagascar: Coua serriana, Brachypteracias squamigera, Oriolia bernieri and Euryceros prevostii. All species of Coua characteristic of humid forest are present.

Non-bird biodiversity: Lemurs: Varecia variegata variegata (EN), Indri indri (EN), Propithecus diadema diadema (EN), Daubentonia madagascariensis (EN). Carnivore: Fossa fossana (VU).
