Justification
This species has an extent of occurrence (EOO) that greatly exceeds the threshold for a threatened category. The estimated area of occupancy (AOO) and inferred population size also exceed the thresholds. It is assessed as Least Concern. However, further research is needed to confirm the taxonomy, since Dalbergia balansae, if treated as a separate species, may have a different Red List Category.
