9.6 Southern River Vegetation Complex
The Southern River vegetation complex is characterised by being in the transition
between the Pinjarra Plain and the Bassendean Dunes. This vegetation is described
as open woodland of Corymbia calophylla - Eucalyptus marginata - Banksia species
with fringing woodland of Eucalyptus rudis - Melaleuca rhaphiophylla along creek
beds.
The Southern River vegetation complex is regionally rare with only 12.4% of the
original extent remaining across the Perth Metropolitan Region (PBP, 2005). In 2000,
5.7% of the original extent of the Southern River vegetation complex in the PMR was
protected within the conservation estate with Bush Forever proposing to increase
protection to 10% (Bush Forever, 2000).
The Southern River vegetation complex is also locally rare with only 11.0% of the
original extent remaining in the Shire. Of this, only 7.0% is protected in conservation
estate or Bush Forever and the remaining LNA consists of only 4.0 % of the original
extent, which is threatened by clearing, subdivision and development.
The retention and protection of the Southern River vegetation complex is highly
constrained by land zoning and this was a large consideration when drafting the
target for protection. The opportunity and constraints analysis with regard to
protection of the Southern River vegetation complex is summarised in Table 15.
