A rare forest type found in areas with dark-coloured soil that contains a high level of heavy metal compounds (for example, nickel, chromium, iron and magnesium).The structure of an ultramafic forest depends on its elevation (i.e. height above sea level).In Sabah, protected ultramafic forests can be found on Mount Kinabalu, Mount Tawai near Telupid, and Mount Silam and Mount Danum near Lahad Datu (on the East Coast).
