Bezavona Classified Forest is located 60 km north-west of Andilamena, at the extreme western limit of Madagascar’s eastern forests. The site comprises a chain of mountains, with peaks at Bezavona (1,050 m) and Berangompanihy (1,080 m), Bezavona being part of the Marovoalavo plateau. The hydrological network is dense and dominated by the Antsahaberoy river in the east and in the south, and by the Manantsatrana and Fatakanina rivers in the east. The main vegetation is low- and mid-altitude, dense, humid evergreen forest with a closed canopy (20–30 m high), dominated by trees of Oncostemum, Canarium, Sapotaceae and Erythroxylaceae, as well as by dry-forest species such as Capurodendron perrieri and Erythroxylum amplifolium. Tree-ferns Cyathea, palms and bamboo-lianas are abundant in the understorey. Secondary vegetation is dominated by traveller’s palm Ravenala madagascariensis.
See Box and Tables 2 and 3 for key species. Seventy-nine species are known from the site, of which 51 are endemic to Madagascar, including 11 members of the vanga (Vangidae) family.
