Steve and Terri Irwin have carried out surveys on several Fijian islands and have actually discovered previously unknown populations of the Fijian Crested Iguana. The results of these surveys and details of the direct impact that Steve and Terri's efforts have made have been outlined in a paper written by Terri Irwin.
In addition to conducting field studies, Australia Zoo has supplied uniforms to the ranger responsible for the protection of the island population of Yaduataba so that intruders recognise him as an official. This has greatly increased his ability to prevent unauthorised landings on the island.
Australia Zoo has constructed a state-of-the-art breeding facility to accommodate the requirements of the ARAZPA (Australasian Regional Association of Zoological Parks and Aquaria) insurance population. This program exists to ensure that if a natural disaster ever occurred that resulted in the isolated wild populations becoming extinct, we would have the ability to repopulate the area.
The greatest immediate threat to this species is the existence of feral animals in their habitat. Not only must they compete with feral goats for food, but feral pigs and stoats also eat the Fijian Crested Iguana’s eggs and young offspring.
