Invasions by alien pest species contribute heavily to global biodiversity decline, with invasive mammals having some of the greatest impacts on endemic biota. Pest management within ecological restorations is therefore critical for conserving threatened biota. Coordinating restoration efforts at global scale requires evidence of the relative efficacy of different pest‐managed restoration approaches (“regimes”) for enhancing biodiversity. Our national meta‐analysis of 447 biodiversity responses across 16 ecological restorations quantifies significant benefits for biodiversity over two decades and multiple trophic levels, and across a spectrum of invasive mammal suppression‐to‐eradication regimes. Deeply endemic species had the strongest responses to pest control compared with recent native or introduced biota. Using this information, we predict levels of pest suppression required to confer biodiversity benefits, to guide future management strategies. Our findings provide new evidence that invasive pest control is an effective approach to ecological restoration, to aid decision‐makers in setting objectives and making targeted investments.

有害生物管理的生态恢复的长期生物多样性轨迹：根除与抑制

外来有害生物物种的入侵在很大程度上导致全球生物多样性的下降，而侵入性哺乳动物对地方生物群系的影响最大。因此，生态修复区内的害虫管理对于保护受威胁的生物群至关重要。在全球范围内协调恢复工作需要有证据证明，采用不同的虫害管理恢复方法（“制度”）可以增强生物多样性。我们对横跨16个生态恢复的447种生物多样性反应进行的国家荟萃分析量化了过去20年和多个营养水平以及一系列侵入性哺乳动物抑制-消除机制对生物多样性的重大利益。与最近的本地或引进生物群落相比，深特有物种对害虫控制的反应最强。使用此信息，我们预测赋予生物多样性益处所需的有害生物抑制水平，以指导未来的管理策略。我们的发现提供了新的证据，表明有害生物入侵控制是一种生态恢复的有效方法，可帮助决策者确定目标和进行有针对性的投资。
