].
The tree is selectively felled in the wild for its valuable timber.
This species is restricted to the Madagascar dry deciduous forests, a habitat type that has been severely destroyed by human activity. It has been estimated that the western dry forest has been reduced by approximately 40% since the 1970's and that since human settlement of this region, an estimated 97% of the island’s dry deciduous western forests have been destroyed. With an expanding rural population and increasing degradation of existing arable lands, the pressure on the remaining forest is extremely high. Selective logging and the removal of large trees pose additional threats of forest habitat degradation. The plant is classified as 'Endangered' in the IUCN Red List of Threatened Species(2011)[

Propagation

Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[
