Past and continuing fragmentation and modification of ecosystems, as well as other threatening processes, cause ongoing biodiversity losses and species extinctions in Australia. At the same time as biodiversity declines, government funding for conservation and restoration is diminishing, leading to reduced action and greater reliance on private investment and community groups. In order to maintain and restore biodiverse ecosystems and the essential services they provide, both conservation of existing vegetation and habitat reconstruction are required. In this paper, we summarise the available data on planting area and cost from the Australian Government’s 20 Million Trees programme (2014–2020), the largest recent national‐scale revegetation incentives programme in Australia. We find that the current spatial scale of effort and investment in habitat reconstruction is insufficient to match the scale required to meet national conservation objectives. Furthermore, the funding rate ($/ha) and contracting arrangements are inadequate for the establishment of high‐quality self‐sustaining vegetation needed for the recovery of Australia’s threatened species and ecological communities. We estimate that the minimum amount of funding required for habitat reconstruction is at least five times higher than is provided for current national flagship programmes such as 20 Million Trees. We provide recommendations, designed to assist future habitat reconstruction programmes achieve their long‐term biodiversity objectives.

目标与现实:澳大利亚公共植被投资模型中的空间,时间,财务和社会缺陷

过去和持续的生态系统破碎化和改造以及其他威胁性过程,导致澳大利亚生物多样性的持续丧失和物种灭绝。在生物多样性下降的同时,政府用于保护和恢复的资金也在减少,导致行动减少,对私人投资和社区团体的依赖增加。为了维持和恢复生物多样化的生态系统及其提供的基本服务,既需要保护现有植被,又需要重建栖息地。在本文中,我们总结了澳大利亚政府的2000万棵树木计划(2014-2020年)的可利用面积和成本数据,这是澳大利亚最近最大的国家级植被再造计划。我们发现,目前在生境重建方面的努力和投资的空间规模不足以匹配实现国家保护目标所需的规模。此外,资助率(美元/公顷)和承包安排不足以建立恢复澳大利亚受威胁物种和生态社区所需的高质量的自我维持植被。我们估计,栖息地重建所需的最低资金至少比目前的国家旗舰计划(例如2000万棵树)提供的资金高出五倍。我们提供建议,旨在帮助未来的栖息地重建计划实现其长期生物多样性目标。供资率(美元/公顷)和承包安排不足以建立恢复澳大利亚受威胁物种和生态社区所需的高质量的自我维持植被。我们估计,栖息地重建所需的最低资金至少比目前的国家旗舰计划(例如2000万棵树)提供的资金高出五倍。我们提供建议,旨在帮助未来的栖息地重建计划实现其长期生物多样性目标。供资率(美元/公顷)和承包安排不足以建立恢复澳大利亚受威胁物种和生态社区所需的高质量的自我维持植被。我们估计,栖息地重建所需的最低资金至少比目前的国家旗舰计划(例如2000万棵树)提供的资金高出五倍。我们提供建议,旨在帮助未来的栖息地重建计划实现其长期生物多样性目标。我们估计,栖息地重建所需的最低资金至少比目前的国家旗舰计划(例如2000万棵树)提供的资金高出五倍。我们提供建议,旨在帮助未来的栖息地重建计划实现其长期生物多样性目标。我们估计,栖息地重建所需的最低资金至少比目前的国家旗舰计划(例如2000万棵树)提供的资金高出五倍。我们提供建议,旨在帮助未来的栖息地重建计划实现其长期生物多样性目标。
