The tree is harvested from the wild for its edible seeds as well as providing material for weaving, rope making etc.
This palm is much less common today than 50 years ago. Although locally abundant in protected ravines, most of the population is being reduced by the cultivation of maize and the harvesting of the plant for fibre and leaves. It is classified as 'Endangered' in the IUCN Red List of Threatened Species(2011)[

Propagation

Seed - best sown as soon as it is ripe. It usually germinates freely. Stored seed is more difficult to germinate, it should be pre-soaked for 24 hours in warm water before sowing. The seedlings quickly send down a taproot, though not as large as from other members of the genus, and so need to be in deep pots[

]. When they are large enough to handle, prick the seedlings out into deep, individual pots and grow them on until large enough to plant out.
Traditionally, the seeds are allowed to dry completely for a couple of months in a cool, dry place. They are then planted on top of a loose, moist soil mix, under a 5 - 8cm blanket of moist sphagnum in a place which is cool at night and warm in the day. This helps with oxygen exchange in and out of the seed coat, which breaks down natural growth inhibitors in the seed. Germination can begin within a few weeks[
