The Myanmar coastal rain forests occupy the coastal lowlands of Myanmar. It extends from the Naf River, which forms the border between Myanmar and Bangladesh, along the Rakhine coast. It also occupies the lower basins of the Irrawaddy and Sittaung rivers, and the coastal lowlands of Mon State and Tanintharyi Region along the Andaman Sea. In Rakhine it is bounded on the east by the Mizoram-Manipur-Kachin rain forests, which occupy the lower slopes of the Arakan Mountains. In the Irrawaddy and Sittaung basins, the Irrawaddy moist deciduous forests lie inland to the north, while the Irrawaddy freshwater swamp forests occupy the wide Irrawaddy Delta to the south. Further east, the Kayah-Karen montane rain forests and Tenasserim-South Thailand semi-evergreen rain forests cover the eastern mountains, and another enclave of the Irrawaddy moist deciduous forests lies in the lower Salween basin. The Myanmar Coast mangroves fringe the coast and river estuaries.
