Madagascar’s Eastern Rainforests extend in a discontinuous band almost from Vohemar in the north-east, right down to tracts of montane rainforest near Fort Dauphin on the south-east coast. Once, this rainforest band, the ‘Madagascar Sylva’, had no equal and remains a treasure chest for naturalists, where discoveries new to scientists are still appearing on a regular basis. It is this ecotype which holds the greatest biodiversity, so a visit to at least one rainforest is a ‘must’ for any visitors spending time in the country.
