The 16:6 Heritage Trust comprises four separate Heritage agreements that share one or more boundaries to represent just over 2000 acres of native Vegetation situated in the Mid Murray depression between the Ridley and Swan Reach Conservation Parks.

The typical Mallee woodland and shrublands represented within 16:6 is dominated by eucalypt species that produce multiple stems from an underground rootstock known as a lignotuber.

There are associated areas that comprise understorey that is quite varied depending upon the soil type, past farming practices and fire regimes to be dominated by hummock grasses (spinifex), chenopods or other woody shrubs.

These four sections of land were partly cleared at the turn of the century for cropping and some grazing, however, by 1945 this semi-arid area was deemed to be untenable. Due to the comparatively intact stratum, this land is home to a quite diverse representation of Flora, fauna, and invertebrate species.

16:6 is fortunate to be the home to a range of unique species including several rare or threatened species
