The site is located 65 km south of Toamasina and 30 km north of Ambila-Lemaitso, on the east coast of Madagascar. It comprises the stretch of the Pangalanes Canal between Ambila-Lemaitso and Tampina, as well as lakes (including Lakes Rasoabe, Rasoamasay, Loakangady and Filomo) and scattered forests. The aquatic vegetation in the canal and lakes includes Cyperus and (rarely) water-lilies Nymphaea and Najas. Islets and banks at the water-margins are covered by Typhonodorum, Carex, Cyperus, Pandanus, Fimbristylis, Melaleuca and Scirpus. On dry land, there are littoral or low-altitude, dense, humid evergreen forests, as well as plantations of Casuarina, Cocos, Eucalyptus, Raphia and Musa.
See Box and Table 3 for key species. Forty-five species are known from the site, of which 13 are endemic to Madagascar. In one recent visit, a few Anas melleri and a significant congregation of Glareola ocularis were noted.
