The total population of Fijian Crested Iguana is around 13,000, with 12,000 of those individuals on the tiny 70 hectare island of Yadua Taba. The remaining estimate of less than 1,000 individuals in total are scattered among 14 other islands. Population estimates for some of these 14 islands suggest that as few as 20 Crested Iguanas may remain on them, while none of these islands have more than a few hundred iguanas. Habitat loss remains the biggest threat, as all three species of Pacific Iguanas are arboreal foliage feeders that depend on a small number of native forest trees for the leaves, flowers, and fruit that they eat. Feral domestic cats, and introduced mongoose and rats are a serious threat to this species on islands where they co-occur with Crested Iguanas.
