The tree is overexploited, and will soon disappear from the timber market as stands have largely been depleted. Protection of remaining stands is badly needed, and Dalbergia baronii will only have a role as commercial timber in the future if plantations become successful, or if the timber is sustainably harvested from natural forest[

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[
