The plant is harvested from the wild for local use of its hard wood.
Although widespread, this is a very rare palm with only about 80 mature trees estimated for the entire distribution range. The population is declining. The main threats to this species are habitat loss through clearance for shifting agriculture and logging and felling of the palm for its trunk which is used as construction material. The plant is classified as 'Endangered' in the IUCN Red List of Threatened Species(2013)[
