Population [top]

Population: Individuals are found in local abundance but are regenerating healthily only in Mahory.
Additional data:

Habitat and Ecology [top]

Habitat and Ecology: Its natural habitat is deciduous forest on limestone, although small trees are also found in disturbed sublittoral scrub.
Systems: Terrestrial

Threats [top]

Major Threat(s): The forest's proximity to a rapidly growing mining town leads to intensive wood and charcoal extraction, grazing and hunting. Subpopulations elsewhere are smaller, show few signs of regeneration and are threatened by the rapid depletion of the habitat through charcoal and timber production.

Conservation Actions [top]

Conservation Actions: The trees are protected from cutting, in places, because of their valued uses.
