Protecting native biodiversity is a difficult prospect in extremely modified landscapes, especially where high‐impact exotic species are widespread. Using new data and a review of the literature, this paper comments on the use of livestock grazing to manage the invasive and highly combustible pasture grass species, Buffel Grass (Cenchrus ciliaris) and thereby help conserve fire‐sensitive Brigalow (Acacia harpophylla) vegetation in reserves in Queensland, Australia. We cite evidence that shows that grazing is a potentially useful management tool in such cases and its use can be compatible with the protection of both fire‐sensitive vegetation and other native plant species within the understorey. However, there are limitations in implementing grazing within conservation reserves including the lack of a clear understanding of the influence of grazing on biodiversity and resource condition. Importantly, we highlight secondary invasion by the exotic grass Indian Couch (Bothriochloa pertusa) as a key emerging threat that may undermine the biodiversity benefits gained by grazing in reserves. Grazing can be a useful tool for conservation management in particular scenarios, but the associated risks demand accompanying monitoring and reporting of positive and negative impacts to ensure the fundamental aim of biodiversity protection is being achieved.

在昆士兰零散的景观中管理牲畜放牧以保护成果

在经过高度改造的景观中，尤其是在高影响力外来物种广泛分布的地区，保护本地生物多样性是一个困难的前景。利用新数据和文献综述，本文评论了使用放牧牲畜来管理侵入性和高度易燃的牧草种类，即Buffel Grass（Cenchrus ciliaris），从而有助于保护火敏的Brigalow（Acacia harpophylla））澳大利亚昆士兰州保护区的植被。我们引用的证据表明，在这种情况下，放牧是一种潜在有用的管理工具，放牧的使用可以与保护林下层的火敏感植物和其他本地植物物种兼容。但是，在保护区内实施放牧存在局限性，包括缺乏对放牧对生物多样性和资源状况的影响的明确了解。重要的是，我们强调了异国草印度沙发（Bothriochloa pertusa），这是可能破坏通过放牧储备获得的生物多样性惠益的主要新威胁。在特定情况下，放牧可以成为保护管理的有用工具，但是相关风险要求伴随监测和报告正面和负面影响，以确保实现生物多样性保护的基本目标。
