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.
