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. Landscape Units Threats specific to Landscape Unit (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)
Encourage community group and volunteer involvement in threatened species recovery or threat abatement programs. Region, Medium priority Encourage the inclusion of Noongar culture in threatened species recovery, threat abatement and education programs. Where possible, build on existing programs or networks (e.g. South Coast NRM Restoring Connections). Region, Medium priority Abatement of Threatening Processes Actions Scale and Priority Update the analysis of threatening processes risks for the threatened species and ecological community of the Fitzgerald Biosphere using Miradi (Section 5) as new data becomes available. Complete the Miradi analysis for the priority species and ecological communities. Region, Low priority Provide input into the Fitzgerald River National Park Fire Management Strategy Paper regarding the fire regime requirements of the threatened and priority species and ecological communities (Action 45). Undertake annual reviews of this strategy paper. FRNP, High priority Ensure up-to-date GIS spatial data of threatened and priority species and ecological communities and their habitat critical is available to Incident Management Teams in the event of a bushfire. Region, High priority Undertake a risk assessment of Phytophthora cinnamomi introduction or further spread through human activity across the Biosphere, in particular relating to habitat critical. Use these results to inform actions and management. Region, High priority Install or upgrade, and maintain hygiene infrastructure at key locations across the Fitzgerald Biosphere. Region, High priority Regularly survey and mapping of the extent of Phytophthora sp. across the Biosphere. Region, High priority Continue to trial and implement containment and eradication methods for Phytophthora cinnamomi infestations at known infestations within the FRNP. FRNP, High priority Continue and expand the Western Shield fox baiting program so that all habitat critical on conservation land for threatened fauna is included. Region, High priority Continue the Integrated Fauna Recovery Program to trial the use of Eradicat™ baits for cat control, with a focus on Western Ground Parrot habitat critical. Include monitoring for impacts on non-target species, in particular Chuditch and Dibbler. FRNP, High priority Commence the use of Eradicat™ baits (subject to the registration of the baits) in the Western Shield Program across the Fitzgerald Biosphere with a focus on fauna habitat critical, in particular for Western Ground Parrot.
