Basalt flows indigenous plants

This information sheet details the indigenous plants found in the Mount Duneed and surrounding basalt flows.

Zone 8 consists of fertile clay to clay loam soils with basalt rock usually present. It includes hills and plains that are mostly poorly drained. The average rainfall is 55 - 62 centimetres.

This area was characterised by grassy woodland with areas of open grassland. Common tree species on the plains included Drooping Sheoke, Swamp Gum, Blackwood and River Red Gum. Yellow Gums were present in isolated populations over the Mount Duneed basalt flow. Understorey species were predominantly Wattles.

Areas of grassland included Kangaroo Grass on the plains and drier sites and Tussock Grass along watercourses.

The volcanic cone of Mount Duneed had a different vegetation structure than the surrounding basalt plains, with certain species, possibly Manna Gum, only occurring in these areas. This landform not only restricts many species from the surrounding area but also provides suitable conditions for others.
