Site description (2001 baseline)
The Anjozorobe forest is part of a branch of the eastern rainforest that runs along the Angavo scarp. The forest lies on metamorphic rock, and the terrain is mountainous and deeply dissected, with steep eroded slopes. The Mananara river, a tributary of the Betsiboka, flows across the western part of the site, which is also crossed by other rivers such as the Sahavila. The main vegetation is mid-altitude, dense, humid evergreen forest. Typical tree genera in the canopy are Canarium, Dilobeia, Diospyros, Eugenia, Protorhus, Sloanea, Schefflera, Tambourissa and Weinmannia. The mid-stratum includes trees/shrubs (Croton, Oncostemum, Vernonia), tree-ferns Cyathea and screw-pines Pandanus. Palms are relatively rare.
Key biodiversity
