This information sheet covers the indigenous plants in the You Yangs granite area.
You Yangs Granite indigenous plants
Zone 15 Consists of poor fertility coarse sandy soils with rock and granite outcrops. Steep to gently sloping hills prone to erosion. The average rainfall is 42 - 50 centimetres.
The information for this zone comes from records of vegetation in the You Yangs Regional Park.
Originally this area had a high diversity of species, many of which are now absent or depleted. Examples of species that are now absent from this area include Silver Banksia and Rosemary Grevillea.
On the granitic outwash fan surrounding the You Yangs, seasonal swamps in broad depressions occur. These areas have a distinct vegetation community consisting of River Red Gum, Prickly Tea-tree, Golden Spray and Rough Paperbark.
On the drier ridges and upper slopes trees include Red Stringybark, Red Ironbark and Moonah. Examples of shrub species were Kangaroo Apple, Rock Correa and a variety of Wattle species.
