Private and Indigenous protected areas are a growing component of the global protected area network. Countries can benefit from a diversity of protected area governance types as a means of creating complementarity and robust national reserve networks. However, strategically allocating resources among governance types requires a greater understanding of similarities and differences in how each protected area governance type represents ecosystems. Using a novel approach based on compositional analysis, we investigate to what extent government, private and Indigenous protected areas represent at-risk vegetation communities that have historically been impacted by habitat loss and fragmentation. We show that the relative representation of at-risk vegetation is different between government, private and Indigenous protected areas. Government and privately protected areas have a higher relative representation of at-risk vegetation over lower concern vegetation, a pattern which was not found for Indigenous protected areas. These results reflect how land tenure, and subsequently protected areas, have historically been allocated in Australia. We urge researchers and policymakers to recognize how the opportunities and constraints associated with government, private and Indigenous protected areas may affect their contribution towards conservation goals. Insights from such studies are important to develop complementary and robust conservation strategies across protected area governance types.

保护区治理类型之间的差异对于保护面临损失和破碎风险的植被群落很重要

私人和土著保护区是全球保护区网络中一个不断增长的组成部分。各国可以从保护区治理类型的多样性中受益，作为建立互补性和强大的国家保护区网络的一种手段。然而，在治理类型之间战略性地分配资源需要更深入地了解每种保护区治理类型如何代表生态系统的异同。使用基于成分分析的新方法，我们调查了政府、私人和土著保护区在多大程度上代表了历史上受到栖息地丧失和破碎化影响的高危植被群落。我们表明，政府、私人和土著保护区之间风险植被的相对代表性是不同的。政府和私人保护区的风险植被相对较低的植被具有更高的相对代表性，这种模式在土著保护区中没有发现。这些结果反映了澳大利亚历来如何分配土地使用权和随后的保护区。我们敦促研究人员和政策制定者认识到与政府、私人和土著保护区相关的机会和限制可能会影响他们对保护目标的贡献。此类研究的见解对于制定跨保护区治理类型的互补和稳健的保护战略很重要。这些结果反映了澳大利亚历来如何分配土地使用权和随后的保护区。我们敦促研究人员和政策制定者认识到与政府、私人和土著保护区相关的机会和限制可能会影响他们对保护目标的贡献。此类研究的见解对于制定跨保护区治理类型的互补和稳健的保护战略很重要。这些结果反映了澳大利亚历来如何分配土地使用权和随后的保护区。我们敦促研究人员和政策制定者认识到与政府、私人和土著保护区相关的机会和限制可能会影响他们对保护目标的贡献。此类研究的见解对于制定跨保护区治理类型的互补和稳健的保护战略很重要。
