Vegetation description

Mangroves are found in the far north near Diégo-Suarez and then continue till south of Morombe, almost exclusively on the western coast, they are found on saline alluvial soils directly exposed to the tides. The main species are: Rhizophora mucronata, Bruguiera gymnorrhiza, Ceriops tagal (Ceriops boviniana), Avicennia officinalis and Sonneratia alba. These species are often mixed with Heritiera littoralis, Terminalia catappa, Thespesia populnea, Derris uliginosa and, on the edge of these stands, Casuarina equisetifolia, as well as a large fern, Acrostichum aureum. The largest stand is found along the Betsiboka estuary. Mangroves are of considerable economic value and extensively exploited for tannin bark from the Rhizophora, Ceriops and Bruguiera genera, and firewood, since they easily regenerating under normal conditions. Typha angustifolia and the fern Acrostichum aureum proliferate on calcareous ground.
