Population justification: Numbers likely remain low throughout its range due to the small land areas and scarcity of its preferred food resources (J.-C. Thibault in litt. 2000, Thibault and Cibois 2017). The species has been described as abundant in some areas and scarce in others (Gibbs et al. 2001); numbers may be higher on some atolls which have remained free from the ravages of introduced predators (Blanvillain et al. 2002). The total number of fruit-doves is difficult to assess and few atolls have been investigated for this species, however based on a mean density of 1 bird per 5-10 ha across several visited atolls, the global population size of this species and Makatea Fruit-dove P. chalcurus together has been estimated at 4,400-9,000 birds (Thibault and Cibois 2017, A. Cibois in litt. 2023). The global population size of P. coralensis is therefore placed in the range 4,200-8,400 birds, roughly equivalent to 2,800-5,600 mature individuals, with no subpopulation likely to exceed 1,000 mature individuals.
Trend justification: The species has disappeared from atolls in the past (Tenarunga and Maturei Vavao) following large-scale expansion of coconut plantations in the 1960s (Thibault and Cibois 2017). Although not currently ongoing at such a scale, the development of coconut groves remains a threat to this species through the destruction of natural vegetation (Thibault and Cibois 2017). Predation by rats may also be driving declines. As such, although the population trend has not been assessed directly, it is precautionarily suspected to be in slow decline given the ongoing threats.
