Local Biodiversity Strategy: - Shire of Kalamunda

Box 11: Proposed Target for the Helena 1, Helena 2, Murray 1, Murray 2 and Dwellingup 2 and
Vegetation Complexes
Retain existing protected areas of the Helena 1, Helena 2, Murray 1, Murray
2 and Dwellingup 2 vegetation complexes and endeavour to protect
additional natural areas in good or better condition that also meet additional
criteria, such as diversity, rarity and connectivity.
9.5 Forrestfield Vegetation Complex
The Forrestfield vegetation complex is associated with the foothills lying to the east
of the Swan Coastal Plain before the Darling Scarp.
The Forrestfield complex vegetation ranges from open forest of Corymbia calophylla
- Eucalyptus wandoo – Eucalyptus marginata to open forest of Eucalyptus marginata
- Corymbia calophylla - Allocasuarina fraseriana - Banksia species. Fringing woodland
of Eucalyptus rudis appear in the gullies that dissect this landform.
The Forrestfield complex is regionally rare with only 7.4% of the original extent
remaining across the Perth Metropolitan Region (PBP, 2005). In 2000, 2% of the
original extent of the Forrestfield vegetation complex in the Perth Metropolitan
Region was protected within the Conservation Estate with Bush Forever proposing to
increase protection to 5% (Bush Forever, 2000).
The Forrestfield complex is locally rare with only 11.6% of the original extent
remaining in the Shire. Of this, only 3.8% is protected in the Conservation Estate or
Bush Forever. The remaining LNAs, which comprise 7.8% of the original extent of
the vegetation complex, are threatened by clearing, subdivision and development.
The retention and protection of Forrestfield 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
Forrestfield vegetation complex is summarised in Table 14.
