Colluvial Plains and You Yangs Plains indigenous plants

Zone 14 Consists of gently sloping hills to flats including gullies with a complex mix of sedimentary soils which include poor fertility non-marine gravels sands and clays which are prone to erosion and moderately fertile marine (limestone) deposits with poor to moderate drainage. The average rainfall is 42 - 50 centimetres.

The area northeast of the You Yangs was grassy open woodland with grassland dominating on the drier sites.

South of the You Yangs the vegetation would have been an open woodland characterised by Drooping Sheoke Grey Box and Yellow Gum with occasional stands of Bulloke. Swamps in seasonally wet depressions were common throughout the area and were dominated by River Red Gum Blackwood and Tangled Lignum.

The north-west of the You Yangs was an open woodland intermixed with grasslands of Kangaroo Grass on the drier sites and Tussock Grass along watercourses and wetter areas.

There are many plant species that were once present in these areas but today are no longer found. These include the White Cypress-pine.
