Heath Goanna Varanus rosenbergi

Heath Goanna Varanus rosenbergiIn Southern South Australia Goannas are our last remaining large, native terrestrial predator and they need our help!

The three large goanna species that occur in Southern SA are the Heath Goanna Varanus rosenbergi, the Sand Goanna V. gouldii and the Lace Monitor V. varius.

The Heath Goanna, also known as Rosenberg’s Goanna, can be confused with the more common, widespread Sand Goanna which is similar in size. The photos above show distinguishing features - including no pale tail tip and curved neck bands. The larger Lace Monitor has a restricted distribution in SA and is more easily distinguished from the others.

 

In South Australia the Heath Goanna is classified as Vulnerable. It was once common across higher rainfall, cooler areas of southern Australia but has suffered dramatic declines on mainland SA. This decline is due to land clearance, habitat fragmentation and degradation, road deaths and predation by cats, dogs and foxes.

In the Mount Lofty Ranges, Northern and Yorke, Eyre Peninsula, Murray Darling Basin and the South East regions the Heath Goanna is classified as Endangered. It is estimated that today less than 100 individuals remain in each of these regions.

The Heath Goanna occupies heath, wet and dry forest and temperate woodlands usually with sandy soils and termite mounds present. It has large foraging areas ranging between 80-1000 hectares. The female lays her eggs during summer, burying them in a termite mound which provides the perfect climate for incubation. The females and often their male partners will actively guard their nest from predators for up to three weeks until the termites have repaired the mound. The young will then hatch in spring where on average less than one in 12 will survive their first year and for those that do survive, breeding age may not be reached for up to nine years.     Melissa Pettigrew
