The Burmese or Myanmar Coast mangroves are an ecoregion in Burma, Malaysia, Thailand and Bangladesh where there were once thick forests of mangroves but today most has been cleared, resulting in loss of habitat for wildlife. [1] [2]
Mangroves were once common in the Irrawaddy River Delta and today exist in three distinct areas, Rakhine State, Ayeyarwady and Tanintharyi Regions, as well as Kutubdia and Moheshkhali islands in Bangladesh
The mangrove flora of Burma include Rhizophora and Xylocarpus mangrove trees, Sonneratias , other Rhizophoraceae, Nypa fruticans and Phoenix paludosa .
The remaining mammals include a small group of wild Asian elephants in Rakhine State, while once common species of mammals and reptiles such as the tiger, the saltwater crocodile (Crocodylus porosus) and the mangrove terrapin ( Batagur baska ) have either disappeared or seriously reduced in number [3]
Bird life however is much richer including waterbirds such as Oriental darter (Anhinga melanogaster), little cormorant (Phalacrocorax nigers), Pacific reef heron (Egretta sacra), great-billed heron (Ardea sumatrana), ruddy shelduck (Tadorna ferruginea), bronze-winged jacana (Metopidius indicus), lesser sand plover (Charadrius mongolus), beach stone-curlew (Esacus magnirostris), black-winged stilt (Himantopus himantopus), Nordmann's greenshank (Tringa guttifer), lesser black-backed gull (Larus fuscus) and common moorhen (Gallinula chloropus). [2]
This is Asia's most depleted area of mangroves, a particularly vulnerable ecosystem. The mangroves have been depleted by increased sediment being brought to the coast by the Irrawaddy, this is a natural process but has accelerated in recent decades following deforestation in inland Myanmar. The mangroves have been even more seriously affected by the large-scale cutting of mangrove trees themselves for timber and to clear land for agriculture and coastal development, all of which is ongoing often illegally. This leaves the remaining mangroves in serious need of protection and planned and existing protected areas include Mein-ma-hla Kyun Wildlife Sanctuary. [4] [5]
As of 2019 [update] in Myanmar, the cutting down of mangroves to turn into charcoal for sale in China and Thailand continues unabated. [6]
The Irrawaddy dolphin is a euryhaline species of oceanic dolphin found in scattered subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. It closely resembles the Australian snubfin dolphin, which was not described as a separate species until 2005. It has a slate blue to a slate gray color. Although found in much of the riverine and marine zones of South and Southeast Asia, the only concentrated lagoon populations are found in Chilika Lake in Odisha, India and Songkhla Lake in southern Thailand.
Sundarbans is a mangrove area in the delta formed by the confluence of the Ganges, Brahmaputra and Meghna Rivers in the Bay of Bengal. Spread across parts of India and Bangladesh, this forest is the largest Mangrove forest in the world. It spans the area from the Baleswar River in Bangladesh's division of Khulna to the Hooghly River in India's state of West Bengal. It comprises closed and open mangrove forests, land used for agricultural purpose, mudflats and barren land, and is intersected by multiple tidal streams and channels. Sundarbans is home to the world's largest area of mangrove forests. Four protected areas in the Sundarbans are enlisted as UNESCO World Heritage Sites, viz. Sundarbans West (Bangladesh), Sundarbans South (Bangladesh), Sundarbans East (Bangladesh) and Sundarbans National Park (India).
The Irrawaddy River is the largest river in Myanmar. Originating from the confluence of the N'mai and Mali rivers, it flows from north to south before emptying through the Irrawaddy Delta in the Ayeyarwady Region into the Andaman Sea. Its drainage basin of about 404,000 square kilometres (156,000 sq mi) covers 61% of the land area of Burma, and contains five of its largest cities.
The Lower Gangetic Plains moist deciduous forests is a tropical and subtropical moist broadleaf forests ecoregion of Bangladesh and India. The ecoregion covers an area of 254,100 square kilometres (98,100 sq mi), comprising most of Bangladesh and the Indian states of West Bengal, Bihar and Tripura, and extending into adjacent states of Odisha, Uttar Pradesh and a tiny part of Assam, as well as adjacent western Myanmar.
Indo-Burma is a biodiversity hotspot designated by Conservation International.
The Chin Hills-Arakan Yoma montane forests is a tropical and subtropical moist broadleaf forest ecoregion in western Myanmar (Burma). Surrounded at lower elevations by moist tropical forests, this ecoregion is home a diverse range of subtropical and temperate species, including many species characteristic of the Himalayas, as well as many endemic species.
The Chao Phraya freshwater swamp forests is a tropical and subtropical moist broadleaf forests ecoregion in Thailand. It occupies the lowlands of the Chao Phraya River watershed in central Thailand. The ecoregion was once home to extensive swamp forests and wetlands. The ecoregion has mostly been converted to agriculture and cities, and very little natural forest remains. The ecoregion's rice paddies and waterways still sustain some wildlife.
The wildlife of Myanmar includes its flora and fauna and their natural habitats.
The New Guinea mangroves is a mangrove ecoregion that covers extensive areas of the coastline New Guinea, the large island in the western Pacific Ocean north of Australia.
The Mizoram–Manipur–Kachin rain forests is a subtropical moist broadleaf forest ecoregion which occupies the lower hillsides of the mountainous border region joining Bangladesh, China's Yunnan Province, India, and Myanmar. The ecoregion covers an area of 135,600 square kilometres (52,400 sq mi). Located where the biotas of the Indian Subcontinent and the Indochinese Peninsula meet, and in the transition between subtropical and tropical regions of Asia, the Mizoram–Manipur–Kachin rain forests are home to great biodiversity. The WWF rates the ecoregion as "Globally Outstanding" in biological distinctiveness.
The Guinean mangroves are a coastal ecoregion of mangrove swamps in rivers and estuaries near the ocean of West Africa from Senegal to Sierra Leone.
Madagascar mangroves are a coastal ecoregion in the mangrove forest biome found on the west coast of Madagascar. They are included in the WWF's Global 200 list of most outstanding ecoregions.
The Indochina mangroves are a large mangrove ecoregion on the coasts of Thailand, Cambodia, Vietnam and Malaysia in Southeast Asia.
The Indus River Delta-Arabian Sea mangroves are a large mangrove ecoregion on the Arabian Sea coast of Sindh Province, Pakistan, and the Gulfs of Kutch and Khambhat in Gujarat, India. The mangroves are the seventh largest mangrove forest in the world.
The Arakan Army, sometimes referred to as the Arakha Army, is an ethno-nationalist armed organisation based in Rakhine State (Arakan). Founded in April 2009, the AA is the military wing of the United League of Arakan (ULA). The Arakan Army are followers of Theravada Buddhism. It is currently led by Commander-in-Chief Major General Twan Mrat Naing and vice deputy commander-in-chief Brigadier General Nyo Twan Awng. The Arakan Army states that the objective of its armed revolution is to restore the sovereignty of the Arakan people. It was declared a terrorist organization in 2020 by Myanmar, and again by the State Administration Council junta in 2024.
The Amapá mangroves (NT1402) is an ecoregion along the Atlantic coast of the state of Amapá in Brazil. The low coastal plain has been formed from recent sedimentation, including sediments deposited by the rivers and sediments carried northward from the mouth of the Amazon River by strong currents and deposited by the tides. The extensive mangroves grow on the newly formed coastal mudflats and along the edges of estuaries. They merge into freshwater várzea flooded forests further inland. The ecoregion is generally well-preserved, although excessive extraction of natural resources including timber and shrimps is a concern.
The Peninsular Malaysian rain forests is an ecoregion on the Malay Peninsula and adjacent islands. It is in the tropical and subtropical moist broadleaf forests biome.
The Myanmar coastal rain forests is a tropical moist broadleaf forest ecoregion on Mainland Southeast Asia. The ecoregion occupies Myanmar's coastal lowlands along the Andaman Sea and the Bay of Bengal.
The Irrawaddy freshwater swamp forests ecoregion covers the freshwater portion of the delta of the Irrawaddy River, set back an average of 70 km from the Bay of Bengal by the saltwater mangroves. To the north is a rainforest belt with less inundated land. The region is extremely fertile due to the river-borne silt, but nearly-total conversion to agriculture has degraded the ecology. There are no fully protected areas in this ecoregion.
