Humans were not the only species that suffered during the Vietnam War. Bombing, tank movements, and the spraying of the defoliant Agent Orange all damaged the natural habitat of this ecoregion on a large scale. These mangroves are now endangered--but where they still exist they provide important habitat for several rare water birds.
Although these mangroves stretch across several climate zones and parts of Vietnam, Cambodia, Thailand, and Malaysia, the largest blocks exist in the deltas of the Mekong and Chao Phraya rivers. Rhizophora, Heritiera, Xylocarpus, Bruguiera, Ceriops, and Lumnitzera tree species dominate these forests, which can reach 32 to 48 feet (10 to15 m), in certain areas. Patches of short palm species are scattered throughout as well. Water birds are plentiful in the mangroves. Storm’s storks, white-winged wood ducks, and spot-billed pelicans make their homes here, along with three near-endemic bird species: the brown-winged kingfisher, Gurney’s pitta, and spectacled bulbul. Only a few pairs of the pitta are thought to remain in the wild. Mammals include the tapir and siamang gibbon. Several reptile species share this ecoregion as well--the monitor lizard, false gavial, and estuarine crocodile.
During the war, about half of the mangroves in southern Vietnam were destroyed. Since then, however, the government has launched a large-scale reforestation program. But the ecoregion is still severely threatened by agricultural development and the cutting of trees, primarily for use as charcoal and fuel. Poaching is a particularly severe threat to reptiles.
