Werribee Plains indigenous plants

This information sheet covers zone 16 in the Geelong region.

Zone 16 Consists of fertile clay to clay loam soils with basalt rock usually present. It includes hills, plains and stony rises that are mostly poorly drained. The average rainfall is 40 - 45 centimetres.

The southern half of this zone was a dry open grassland with few trees and shrubs. Indigenous grasses in this zone consisted mainly of Kangaroo Grass, Wallaby Grass, Spear Grass and Red-leg Grass.

Tussock Grass grasslands occur in the wetter areas and drainage depressions.

Buloke and Grey Box occurred sporadically across the north of the zone with River Red Gum along the watercourses (for example: Lollypop Creek).

River Red Gum and/or Tangled Lignum typically dominate the remaining swamps in this zone that have not been drained.

For a species list for the watercourses and associated escarpments of the Werribee Plains refer to Werribee Plains, Rivers and Watercourses.
