Conservazione

Since 1988, the western bronze-naped pigeon has been rated as a species of least concern on the IUCN Red List. This is because it has a large range, and because its population is stable and thought not to have declined by 30% over ten years or three generations. Although the population size has not been measured, it is thought to be more than the threshold required to warrant it a vulnerable rating. There is no evidence of any population decline of the species, or substantial threat to it.
