The environmental impacts of eradicating dingoes from the landscape are visible from space, a new study shows.
Researchers studied 32 years of satellite imagery along the dingo fence which stretches across Queensland, NSW and South Australia.
They found that areas without dingoes on the south side of the fence had poorer long-term growth than vegetation in areas with dingoes. Dingoes indirectly affect vegetation by controlling numbers of kangaroos and small mammals, ecologist Mike Letnic said on Wednesday. The differences in grazing pressure on each side of the fence were so pronounced they could be seen from space.
With few dingoes preying on them, kangaroo numbers increased, leading to overgrazing, Prof Letnic said.
