[1] A remnant bushland of the Cumberland Plain Woodland, it mainly features native vegetation.

[2] The reserve is so-named because of its abundance of Eucalyptus moluccana, reflecting the pre-European cultural landscape of the area.

The form of the Reserve is typical of the soft undulating hills of the Cumberland Plain, and is located largely on a gentle west-facing slope inside a small water catchment that transiently drains southwards to Prospect.

[1][5] The Reserve is connected to five main environment corridors of remnant vegetation and fauna habitats within the vicinity, such as Gipps Road and Hyland Road Regional Parklands to the south, the Lower Prospect Canal Reserve Cycleway which features disjunct patches of CPW and Alluvial Woodland, Prospect Creek and the Alluvial Woodland within the Long Street Park, the Prospect Reservoir woodland to the west and Greystanes Creek, which ties the Reserve to the major habitat corridors within the City of Parramatta including Toongabbie Creek, Quarry Branch Creek and Lake Parramatta.
