The Klias peninsula in Sabah, Malaysia, with approximately 130 000 ha land area, includes peat swamp forests, mangroves, nipah swamps, freshwater swamp forests, kerangas and open marshes, making it a significant wetlands locality. A general survey conducted under the Sabah Biodiversity Conservation Project's Identification of Potential Protected Areas (IPPA) component revealed that good extents of these various vegetation types remain and should be conserved with careful management planning, even though threats such as fire, drainage of swampland, forest clearing, illegal encroachment, commercial logging and agricultural development have taken a toll on the natural landscapes of the region.
