The Honey Ants Dream. Night falls over the MacDonnel Ranges, the mountain chain in the center of Australia. The highest altitude of this 350 million year old mountain range is 1,531 meters. The range, situated in the center of the central desert, stretches from east to west. The plains and plateaus that surround it are the preferred habitats for the acacia aneura, called mulga, which reaches a height of 15 meters. This tree grows abundantly in the arid zones in the center of Australia. It can survive with only 50mm of rain per year. Northern Territory, Australia
