The ecosystem of the river, mainly forests and brushland, has many indigenous species, such as the Sambirano mouse lemur and Sambirano woolly lemur.[2]
The Madagascar dry deciduous forests occupy much of the river basin, although mangroves are evident at parts of the coastal fringe.[3]
The valley of the Sambirano is the main cocoa producing area of Madagascar. 60% (or 7500 to 10 000 tons yearly) provide from this area. There is an unpaved piste from Ambanja to Marovato, via Benavony, Ambodimanga Ramena, Bemaneviky Ouest, Maevatanana that is hardly practicable.[4] Most of the exported cocoa is therefore transported with boats on the Sambirano river to Ambanja and the National road 6
