Although the introduced mongoose has caused the decline in numbers of several ground-living birds on Viti Levu and Vanua Levu, the rarity of the pink-billed parrotfinch cannot be directly attributed to this or any other introduced vertebrate. The relatively small population is believed to be declining due to continuing deforestation, half of the island's mature woodland having already been cleared for agriculture or planting with mahogany. The best site, Joske's Thumb, was lost in the 1980s. The small population on a single island, together with the expected ongoing decline mean that this species is it is therefore classed as vulnerable on the IUCN Red List.
