We have surveyed and mapped the four main vegetation communities at Rubicon using the TASVEG 3.0 classification system. Their distribution is determined mainly by the differing drainage across the property, and to a lesser extent the fire history.
11 ha of the 20 ha at Rubicon supports Eucalyptus amygdalina coastal forest and woodland (DAC). DAC favours the drier sandy soils, where bracken is a common understory compnent. Where soils are damper, bracken tends to disappear, a habitat that we cometimes call "DAC damp". This damper facie occupies a fair proportion of the DAC habitat.
There is 5.8 ha of Wet heathland (SHW) at Rubicon. Most of this is dominated by sedges rather than shrubs. This vegetation community would probably become more shrubby in the absence of disturbance and ultimately could turn into Eucalyptus ovata forest and woodland (DOV).
Eucalyptus ovata forest and woodland (DOV), is a threatened vegetation community, that extends over 2.4 ha. Much of this has a dense shrubby understory in very wet places. Some DOV consists of immature trees growing over wet heathland.
Rubicon supports 0.5 ha of fresh water aquatic sedgeland and rushland (ASF), another threatened vegetation community. These are the lower-lying places in wet heathland, where water persists for long enough in most years to create a distinctive wetland vegetation.
