被海洋和沙漠包围，澳大利亚西南部（SWA）孤立的地中海气候地区包括九个生物区（约4400万公顷）。在这个全球生物多样性热点地区，景观的生态完整性受到森林砍伐、破碎化、开发和引进生物群的破坏。四个相互关联的景观（天鹅海岸平原;西南森林;旺都林地;和大西部林地）之间的性质和变化程度各不相同。冈瓦纳人的观点强调古老的生物群和深层时间的文化成分。遗迹和保护区在恢复冈瓦纳景观的生态完整性方面特别重要。在这些古老的和邻近的景观中恢复任务的性质和规模需要比最近的景观更高水平的投资和更多的时间。生态完整性的保护、养护、恢复和重建需要在每个景观中采取多种方法，并考虑整体。积极保护生物群并最大限度地减少工业和农业使用的影响是优先事项。整合气候焦点和重新思考火灾是人为气候变化下未来轨迹的关键恢复考虑因素。协调工业规模恢复和积极保护的立法授权必须成为恢复生态完整性的社会优先事项。
Bounded by ocean and desert, the isolated, predominately Mediterranean‐climate region of south‐western Australia (SWA) includes nine bioregions (circa 44 million hectares). The ecological integrity of the landscapes in this global biodiversity hotspot has been compromised by deforestation, fragmentation, exploitation, and introduced biota. Nature and degree of transformation varies between four interconnected landscapes (Swan Coastal Plain; South‐west Forests; Wandoo Woodlands; and Great Western Woodlands). A Gondwanan perspective emphasizes a venerable biota and a cultural component to deep time. The particular importance of remnants and protected areas is recognized in restoring ecological integrity to Gondwanan landscapes. The nature and magnitude of the restoration task in these ancient, and neighboring, landscapes require higher levels of investment and more time than do recent landscapes. The protection, conservation, restoration, and rehabilitation of ecological integrity require multiple approaches in each landscape as well as consideration of the whole. Active conservation of biota and minimizing the impact of industrial‐ and agricultural‐use are priorities. Integrating a climate focus and rethinking fire are critical restoration considerations to future trajectories under anthropogenic climate change. A legislative mandate to coordinate industrial‐scale restoration and active conservation to build from protected areas must become a societal priority to restore ecological integrity.
