The site comprises the Sahamalaza peninsula, the 30-km-long bay itself, the mangrove to the east of the peninsula (8,400 ha) and the coral reefs to the west (more than 10,000 ha). The peninsula has steep slopes, rising to 170 m in the southern part. Its west coast is stony and rocky, with mangroves. The principal rivers flowing into the bay are the Andranomalaza, which passes the town of Maromandia, and the Manamboro and Samonta, which lie to the south. On the slopes, the vestiges of a dense, dry deciduous forest form two blocks, situated in the south (Analavory Forest) and west (north of Ambinda village) of the peninsula. The dominant tree species include Dalbergia, Albizia and Tamarindus. The north-eastern part has been cleared of forest, but seems to be regenerating. In the mangroves, all eight mangrove tree species found in Madagascar are present, and can reach more than 8 m in height.
See Box and Table 3 for key species. The site is important for several pairs of Haliaeetus vociferoides and large flocks of Sterna bengalensis.
