The southern portion of the property is new volcanics, stony plains, and is zoned Rural and Environmental Rural. Originally this would have been covered by open grassy woodland dominated by grey box, yellow box and buloke. Despite past grazing and cropping activity, the open grassy woodland character is still retained through patches of mature trees and considerable regeneration of both overstorey and understorey species across much of the plains. Open grassland covers approximately 50% of the plains section. These grasslands are a disclimax community normally dominated by windmill grass, wallaby grass and spear grasses. Extensive environmental work has been carried out, with serrated tussock being a particularly serious problem as it has tended to displace the native grasses. A program of burning and spraying of tussock and boxthorn has reduced the infestations enormously and has enabled regeneration of native species to occur. A small lignum swamp is located in the north west corner of the property.
A steeply sloping rocky escarpment (approximately 40 metres in height) forming a portion of the Werribee River Gorge leads from the plains to the river below. The escarpment is well vegetated with pepper trees (schinus molle) and remnants of native species. Rock outcrops along the top of the escarpment provide excellent views along the Werribee River and across the basalt plains opposite, although in recent years a housing development has created visual intrusion. Moonah (melaleuca lanceolata) is the dominant tree along the top of the escarpment, which also contains an excellent stand of white cypress pine of state significance. A new housing development is visible to the north west. The riverine flats support a continuous belt of riverine red gum woodland providing an important habitat and landscape feature along the Werribee River.
The property supports abundant wild life including such mammals as eastern grey kangaroo, swamp wallaby, koala, possums, echidna and white-striped mastiff-bat. Birds commonly sighted are brown falcon, peregrine falcon, sparrow hawk, whistling kite, wedge tail eagle, kookaburra, sulphur crested cockatoo, galah, eastern rosella, king parrot, rainbow parakeet, australian raven, magpie lark, white-backed magpie, superb wren, new holland honeyeater, zebra finch, willie wagtail, spine-tailed swift, black swan, pelican, black cormorant, little pied cormorant, and spur-winged plover, to name just a few.
