Site description Zahamena National Park is located 40 km north-east of Ambatondrazaka and 4 km from Manakambahiny-East. The terrain is very undulating, with several steep-sided valleys. The park is in two areas, west and east, partially separated by a large enclave which includes several villages. The valleys are drained by rivers, the most important of which are the Sahatavy and its tributary, the Sarondrina. A network of rivers in the north-west of the park flows into Lake Alaotra (IBA MG046). At low altitudes the dense, humid evergreen forest has a canopy 15–20 m high and 25-m-high emergents, typically with trees of Tambourissa, Weinmannia, Diospyros, Ravensara and Dalbergia. The shrub layer is dominated by tree-ferns Cyathea and screw-pines Pandanus. There are also areas of secondary forest. The dense, humid evergreen forest extends to mid-altitudes, above which there is dense, sclerophyllous montane forest. The forest on the slopes has a denser shrub and ground layer, dominated by herbs (Impatiens, Begonia) and ferns Polystichum.
