Groundwater coming up through rock layers as springs are essential to life in the Flinders Ranges.
Even in the presence of a running spring, Euros (Macropus robustus) are known to dig soaks in creekbeds for subterranean water.
Flies such as these settle on the surface of natural springs in the Flinders Ranges. The secret of their buoyancy is revealed in the shadow.
Tobacco Bush Creek flows across the Outback Hwy north of Copley. This groundwater provides a vital flowing waterway for many species including fish, reptiles, invertebrates and birds. Birds SA reported 13 species of birds in the creek during a brief 6 hour survey in April 2018, finding the following:
- Grey Teal
- Australasian Grebe
- Hoary-headed Grebe
- White-faced Heron
- Black-fronted Dotterel
- Nankeen Kestrel
- White-winged Fairywren
- White-backed Swallow
- Singing Honeyeater
- Black-faced cuckooshrike
- Zebra Finch
- Australian Pipit
Well worn tracks of native animals cover the banks of the watercourse.
