Barrabool Hills indigenous plants

Zone 9 consists of moderately fertile sandy loam soils on tertiary alluvial (sandstone) deposits. The gently sloping hills, some escarpments and gullies are mostly well drained. The average rainfall is 55 - 60 centimetres.

This area was characterised by a Drooping Sheoke woodland with a grassy and/or a heathy understorey largely made up of Wattle species, Silver Banksia and Sweet Bursaria.

Along the ridges and slopes Drooping Sheoke, Moonah, Cherry Ballart and Lightwood dominated the landscape while along the drainage lines Blackwood, River Red Gum, Swamp Gum and Manna Gum grew.

Along the drier sandy gully sides, species such as Manna Gum, Shrub Violet and Sweet Bursaria were found.

Unfortunately many of this area’s tree species have been cleared. White Cypress-pine, Yellow Gum and Swamp Gum can no longer be found.

Shrub species restricted to the drier areas included Kangaroo Apple, Silver Banksia, Sweet Bursaria and Giant Hop-bush. Along the lower slopes and drainage lines Silver Wattle, Hemp-bush, Prickly Tea-tree and Tangled Lignum grew.

Throughout the hills, Kangaroo Grass was present over the upper and mid slope areas. Tussock Grass would have dominated lower, wetter and south-facing slopes.
