For harvesting the bark for tanning, the trees are felled and the bark is separated from the logs by beating them with wooden mallets. The strips obtained are then sun-dried, chopped into small chips and sent to tanneries. The bark is often only a by-product; the trees are primarily felled for timber and fuel[

Propagation

Seed - best sown when fresh and still moist. Seeds can be extracted from the pods, while seeds that are ejected by sheep during rumination or those from cattle and goat droppings may also be collected. These latter seeds germinate easily due to fermentation and moistening which soften the seedcoat[

If not sown when moist, the seed develops a hard seedcoat and may benefit from scarification before sowing 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.
The germination rate of moist or treated seed generally varies from 50 - 90%, it usually starts 1 - 3 weeks after sowing and is mostly complete in one month[
