Protected areas are a fundamental mechanism for ensuring the persistence of biodiversity. The strategic policy objectives set by governments for protected area land acquisition are strong determinants of biodiversity outcomes. An examination of these objectives is necessary to determine those most influential in designing protected area networks and understand why Australia's extinction rates exceed those elsewhere despite actively establishing protected areas over the past several decades. To examine spatio-temporal trends in policy objectives for protected areas, we evaluated the strategic priorities in Federal, State, and Territory policy documents across Australia between 1992 and 2019 using thematic analysis. We classified priorities into seven themes: adequacy, Indigenous and cultural values; representation of ecosystem and species types; threatened species and their habitat; social and recreational values; unique values and avoiding threatening processes. We found that the representation of ecosystem and species types was the most prevalent theme in policy documents, and the least common theme was social and recreational values. We posit several reasons for this trend and warn that emphasizing extent, in terms of area or representativeness, may diminish the effectiveness, efficiency, and impact for biodiversity outcomes. We found that policies were generally supportive of the strategic identification of particular species or communities that would quantifiably benefit from protection (referred to as avoided loss). Risked-based approaches to the establishment of protected areas are supported by modern conservation literature to enhance the protected area network's effectiveness. To maximize limited resources, we recommend that governments continue encouraging urgency to avoid species and habitat loss in their strategic priorities. This urgency should be accompanied by clear and consistent funding for on-the-ground actions which facilitate the socio-ecological outcomes that characterize modern protected ...

[Extract] This report provides a synthesis of research on climate change and coastal science in the Torres Strait, and has been produced for the Australian Government's Marine and Tropical Sciences Research Facility (MTSRF). It identifies and summarises work to date on reef evolution, hydrodynamics and sedimentary environments throughout the Torres Strait. It describes the island dynamics at Boigu, Saibai, Masig, Poruma, Warraber and Iama Islands. Numerous studies relating to climatic change are reviewed and the most relevant regional predictions for climate change in the Torres Strait are presented. The potential physical and ecological impacts of these changes in the Torres Strait are also identified. Adaptation and mitigation measures are suggested and their outcomes and consequences are evaluated. The key principles from sustainable land use plans on the islands are summarised and knowledge gaps in the fields of both coastal and climatic science are identified to guide future research.
