Goannas are the last remaining large, native, terrestrial predators in southern South Australia, and they need our help!
In southern South Australia, goanna numbers are declining. A loss of suitable habitat makes it difficult for goanna populations to persist, and much of their remaining habitat is degraded or fragmented. We need to know more about goanna populations, particularly information about where they are and how many there are. But it is difficult for scientists to find them as there are so few of them remaining. For example, it is estimated that there are now fewer than 100 Rosenberg’s Goannas (also known as Heath Goannas) in each of the seven mainland Natural Resources Management regions of South Australia (see here for a map of the regions), and they are a Threatened Species.
You can help to gather valuable information needed on goannas in South Australia. This information is vital for the development of management strategies to address the loss of goannas.
How to participate
If you see a goanna please let us know where you saw it (see below). Goannas are shy, so do not approach or disturb them. Do not disturb the habitat either, just make a note of the location and, if possible, take a photo. You can then submit your sighting using our online system.
Be careful: do not chase, catch or handle goannas. Ensure your personal safety at all times, particularly if you see a goanna on a road.
Injured goannas: If you see an injured goanna, call the Fauna Rescue hotline on 8289 0896.
Any questions? You can contact us via email: firstname.lastname@example.org or by phone: 08 8302 9999.
