Risk of the threats were not ranked using Miradi due to the complexity of the Landscape Units. Each Landscape Unit responds differently to threatening processes due to different physical characteristics and these differences need to be understood when considering threat abatement. Table11: The most significant threatening processes and susceptibility to these threats of each of the Landscape Units of the Fitzgerald Biosphere. Threats specific to Landscape Unit Landscape Units (including current level of threat within landscape units plus potential threats based on specific susceptibility of the unit to threat) Fraser Coastal Stable system - sensitive to frequent disturbance Climate change (species at edge of range, restricted, endemic) Phytophthora (highly susceptible flora and vegetation communities) Depositional Dynamics Highly dynamic system - adapted to frequent ground disturbance Weed infestation Salinisation Erosion Siltation of waterways Depositional Eocene Relatively dynamic system - resilient to disturbance to some degree Weed infestation Frequent fire (in particular the mallet and moort communities) Esperance Sandplain Relatively stable system - sensitive to frequent disturbance Phytophthora (highly susceptible Banksia communities) Climate change (species at edge of range) Fragmentation of habitat Salinisation (saline and freshwater lake systems)
