Formatted Abstract/Summary
Ultramafics are characterised by high concentrations of magnesium and nickel, low concentrations of calcium, low water retention capacity and low concentrations of essential plant nutrients in soils derived from this substrate. These extreme chemical soil condition force plants to adapt to survive. Sabah is one of the richest areas in the world for plant diversity on ultramafic substrates. A range of species, including a number of pitcher plants (Nepenthaceae), orchids (Orchidaceae) and trees and shrubs are endemic to ultramafic areas in Sabah, often occurring on a few, or even just a single, site. Ultramafic vegetation types in Sabah are severely threatened by land-clearing activities. Although only a small minority of the geological substrates in Sabah are ultramafic, ecosystems on these substrates have a disproportionately high number of endemic and rare plant species. Destruction of these types of ecosystems, in particular, can potentially result in extinction of plant species.
