Western dry forest

Fiji crested iguana

Brachylophus vitiensis

Critically Endangered CITES I

John Gibbons described this species in 1981. It is paler than the banded iguanas, with a more obvious crest of spines, and it can shift toward black when agitated. It belongs to Fiji’s dry forest — a habitat that has been burned, browsed and fragmented for generations.

Most of the global population lives on Yadua Taba, a sanctuary island of about 70 hectares. Published estimates have put the world total around 13,000 animals, with the vast majority on that one island. That is a conservation success and a single-point failure at the same time.

Crested iguanas have received more recovery attention than the banded species: predator control, habitat protection, and assurance colonies. Other western islands still hold remnant groups, sometimes rediscovered only when an animal turns up on a resort lawn.

Range

Northwestern Fiji dry forest. Yadua Taba is the stronghold.

Size

The largest living Brachylophus. A long tail still makes up most of the length.

Why CR

Tiny area of occupancy, invasive predators, and fire in dry forest. One island holds almost everyone.

Sanctuary

Yadua Taba is managed as a crested iguana reserve. Visiting wild populations is not a casual tourist activity.
