It is high in biodiversity and is a supplementary report to A Strategic Framework for values and endemism but many of these natural values are Biodiversity Conservation Report A: For decision-makers highly threatened. Species and ecological communities are and practitioners. This report describes the systematic at risk from current and historical land-use, Phytophthora conservation planning process and provides guidance on how dieback, salinity, feral animal predation and weed invasion. to interpret and implement the results. Over the past 30 years, a range of federal, state and local Systematic conservation planning is a complex process. Decisions government, and community initiatives have sought to address and trade-offs are made to balance veracity with timely delivery. such threats, yet biodiversity loss continues. As such, the role of Technical Report B: For practitioners of The Southwest Australia Ecoregion Initiative (SWAEI) is a conservation planning is to guide those choosing to undertake a consortium of representatives from local, state and federal systematic conservation planning process. governments, environmental non-government organisations and natural resource management (NRM) groups concerned about the ad hoc nature of biodiversity planning and Dermot O’Gorman management initiatives. The consortium has undertaken an CEO WWF-Australia extensive systematic conservation planning project that aims to identify highly prioritised areas, or Zones for Conservation Action (ZCA). This project delivers a coordinated, strategic planning framework for the conservation of biodiversity in the south-west of Australia. It is based on scientific principles, informed by experts, and has been developed using methods that are widely used and easy to interpret.
