It is estimated that over the past three generations the population of Pterocarpus dalbergioides has declined by at least 30% as a result of historical timber harvesting. Logging of the species is now more strictly controlled but the species habitat is becoming fragmented. The overall population size of the species is not known but it is considered to be in decline due to poor seed regeneration, with no saplings or seedlings being found across 106, 0.1 ha sites. The tree is long lived and thought to need forest disturbance for there to be significant regeneration. The plant is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2018)[
