While some trees were cleared from the Arboretum site in the past, several large River Red-gums remain and much of the native understorey is still present. A watercourse runs diagonally through the Arboretum from north-east to the south-west. The natural stream has been extensively modified and dammed as a series of ponds that form a major wetland. The main plantations of trees are to the west and north of the wetland. Apart from the western boundary, the ground layer between the mounds still retains a good cover of native plant species. Further east and north of the old saw mill is an area of Plains Grassy Woodland with some mature and juvenile River Red-gums over an understorey dominated by native grasses and forbs. Part of the woodland has been marked out with timber bollards.
Old Ararat Road, Dunkeld, a town on the Glenelg Highway 270 km from Melbourne. The native grassland and grassy woodland is in the eastern section of the arboretum, east of the old saw mill.
