The Sunda Shelf mangroves ecoregion, in the mangrove biome, are on the coasts of the islands of Borneo and eastern Sumatra in Malaysia and Indonesia. They are home to the proboscis monkey.
As well as being an important habitat for terrestrial and marine wildlife mangroves preserve the shape of the coastline.
Sunda Shelf mangroves Wikipedia
There are more plant species here than in most mangrove forests in the world, with five different types of mangrove dominating parts of the region as follows: Avicennia and Sonneratia species on the coast where water is saltiest and the tidal wash strongest; Rhizophoras and Bruguieras in the swampy areas just behind them; and Nypa fruticans palms in the freshwater streams further inland still.
Mammals of the mangroves include the proboscis monkey (Nasalis larvatus), which solely inhabits these swampy coastal habitats. There are also many species of birds.
Mangroves are vulnerable ecosystems as trees are cut for timber, firewood and to clear land for agriculture and urban development such as shrimp farming. This loss of habitat persists despite the mangroves being part of a large number of protected areas including: on Borneo Bako National Park in Malaysia and Tanjung Puting and Gunung Palung National Parks in Indonesia, and on Sumatra Berbak and Sembilang National Parks.
