Abstract

Australia is a global leader in land clearing and biodiversity loss. The overwhelming majority of land clearing within Australia and, globally, is driven by agricultural conversion. The importance of agricultural lands also leads to the concentration of habitat protection in landscapes that do not support productive land uses, which might contribute to species conservation in marginal habitat. Using an integrated agricultural capability map and threatened vertebrate fauna range maps, we show that observed biases in protected area location have varied impacts at the species level. Specifically, threatened vertebrate fauna with habitat capable of supporting high-value productive lands received less protection and experienced greater habitat loss. Similarly, almost all species assessed received protection in the portions of their ranges less conducive to productive land uses. Finally, we identify regions of Australia at risk of future land clearing and the species likely to bear the brunt of the impacts. Our results demonstrate the importance of protecting land capable of supporting productive uses to conserve the most affected threatened species.

澳大利亚农业利益损害濒危动物保护
澳大利亚在土地清理和生物多样性丧失方面处于全球领先地位。澳大利亚境内以及全球绝大多数土地清理都是由农业转型推动的。农业用地的重要性也导致栖息地保护集中在不支持生产性土地使用的景观中,这可能有助于边缘栖息地的物种保护。使用综合农业能力图和受威胁脊椎动物区系范围图,我们表明,在保护区位置上观察到的偏差在物种层面上有不同的影响。具体而言,栖息地能够支持高价值生产力土地的受威胁脊椎动物受到的保护较少,栖息地损失更大。同样,几乎所有被评估的物种都在其范围内不太利于生产性土地利用的部分受到保护。最后,我们确定了澳大利亚未来面临土地清理风险的地区,以及可能首当其冲的物种。我们的研究结果表明了保护能够支持生产用途的土地以保护受影响最严重的濒危物种的重要性。

期刊介绍: Conservation Letters is a reputable scientific journal that is devoted to the publication of both empirical and theoretical research that has important implications for the conservation of biological diversity. The journal warmly invites submissions from various disciplines within the biological and social sciences, with a particular interest in interdisciplinary work. The primary aim is to advance both pragmatic conservation objectives and scientific knowledge. Manuscripts are subject to a rapid communication schedule, therefore they should address current and relevant topics. Research articles should effectively communicate the significance of their findings in relation to conservation policy and practice.
