The restoration of habitats degraded by industrial disturbance is essential for achieving conservation objectives in disturbed landscapes. In boreal ecosystems, disturbances from seismic exploration lines and other linear features have adversely affected biodiversity, most notably leading to declines in threatened woodland caribou. Large-scale restoration of disturbed habitats is needed, yet empirical assessments of restoration effectiveness on wildlife communities remain rare.
We used 73 camera trap deployments from 2015 to 2019 and joint species distribution models to investigate how habitat use by the larger vertebrate community (>0.2 kg) responded to variation in key seismic line characteristics (line-of-sight, width, density and mounding) following restoration treatments in a landscape disturbed by oil and gas development in northeastern Alberta.
The proportion of variation explained by line characteristics was low in comparison to habitat type and season, suggesting short-term responses to restoration treatments were relatively weak. However, we found that lines with characteristics consistent with restored conditions were predicted to support an altered community composition, with reduced use by wolf and coyote, thereby indicating that line restoration will result in reduced contact rates between caribou and these key predators.
Synthesis and applications. Our analysis provides a framework to assess and predict wildlife community responses to emerging restoration efforts. With the growing importance of habitat restoration for caribou and other vertebrate species, we recommend longer-term monitoring combined with landscape-scale comparisons of different restoration approaches to more fully understand and direct these critical conservation investments. Only by combining rigorous multispecies monitoring with large-scale restoration, will we effectively conserve biodiversity within rapidly changing environments.

多物种建模揭示了栖息地恢复重建北方脊椎动物群落动态的潜力

恢复因工业干扰而退化的栖息地对于在受干扰的景观中实现保护目标至关重要。在北方生态系统中，地震勘探线和其他线性特征的干扰对生物多样性产生了不利影响，最显着的是导致受威胁的林地驯鹿数量减少。需要大规模恢复受干扰的栖息地，但对野生动物群落恢复有效性的实证评估仍然很少。
我们使用了 2015 年至 2019 年的 73 个相机陷阱部署和联合物种分布模型来研究大型脊椎动物群落（> 0.2 kg）的栖息地使用如何响应关键地震线特征（视线、宽度、密度和丘陵）的变化) 在艾伯塔省东北部受石油和天然气开发干扰的景观中进行恢复处理。
与栖息地类型和季节相比，由线特征解释的变异比例较低，表明对恢复处理的短期反应相对较弱。然而，我们发现具有与恢复条件一致的特征的线预计支持改变的群落组成，减少狼和土狼的使用，从而表明线恢复将导致驯鹿和这些主要捕食者之间的接触率降低。
合成与应用。我们的分析提供了一个框架来评估和预测野生动物社区对新兴恢复工作的反应。随着驯鹿和其他脊椎动物物种栖息地恢复的重要性日益增加，我们建议进行长期监测，并结合不同恢复方法的景观规模比较，以更全面地了解和指导这些关键的保护投资。只有将严格的多物种监测与大规模恢复相结合，我们才能在瞬息万变的环境中有效地保护生物多样性。
