 The Sarawak coastline is covered with mangrove and nipah forests. It forms two percent of the total forested area in Sarawak, most commonly found in the estuarine areas of Kuching, Sarikei, and Limbang. The major trees found here include: bako (Rhizophora), nipah palm (Nypa fruticans), and nibong (Oncosperma tigillarium). Peat swamp forests that cover 16 percent of the forested land are concentrated in southern Miri and the lower Baram Valley. The main trees in the peat swamp forests are: ramin (Gonystylus bancanus), meranti (Shorea species), and medang jongkong (Dactylocladus stenostachys). Kerangas forest occupies five percent of the total forest area, while Dipterocarpaceae forests occupy mountainous areas. Several plant species have been studied for their medicinal properties.
