森林恢复已成为全球保护的优先事项，特别是在热带地区，那里剩余的森林生态系统有很大一部分已经退化。为了通过有限的保护资金实现雄心勃勃的恢复目标，必须优先考虑将提供最大生物多样性价值的地区。在这里，我们将联合收割机机载激光扫描与广泛的相机陷阱数据集相结合，以保护和恢复退化的采伐森林梯度为目标。我们证明了三维栖息地结构的重要性，会计定义森林的适宜性和恢复潜力的哺乳动物。因此，我们提供了一个强大的定量框架，优先退化的森林恢复生物多样性的考虑。热带森林生态系统正面临着前所未有的退化程度，严重损害了野生动物栖息地的适宜性。尽管生物多样性在森林再生中发挥着根本作用，但根据其野生生物价值确定退化森林并将其列为恢复或养护的优先事项，仍然是一项重大挑战。将人为改造的热带森林简单地分类为完整森林与退化森林，忽视了三维森林结构可能对物种分布的影响，这也削弱了描述生境选择的努力。在这里，我们开发了一个框架，以确定保护和恢复的机会，在婆罗洲采伐森林。我们耦合高分辨率的机载光探测和测距（LiDAR）和相机陷阱的数据来表征热带哺乳动物群落的响应在整个退化梯度的三维森林结构的变化。哺乳动物是最敏感的协变量，占明确的垂直和水平的特点，森林和积极选择结构复杂的环境，包括高大的树冠，增加植物面积指数在整个垂直列，和可用性更大的多样性的生态位。我们表明，哺乳动物是敏感的结构简化，通过干扰，强调维护和提高结构完整的森林的重要性。通过计算物种的发生阈值，以响应森林结构的变化，我们确定退化的森林，如果恢复将提供最大的好处多个高保护价值的物种的地区。该研究表明，使用激光雷达绘制森林结构图的优势，而不是依赖于人类改造的热带森林的过于简单的分类，以优先考虑恢复区域。
Forest restoration has become a global conservation priority, particularly in the tropics where a significant proportion of remaining forest ecosystems are degraded. To achieve ambitious restoration targets via limited conservation funds, areas that will deliver the greatest biodiversity value must be prioritized. Here, we combine airborne laser scanning with an extensive camera trap dataset to target conservation and restoration across a degraded logged forest gradient. We demonstrate the importance of accounting for three-dimensional habitat structure when defining forest suitability and restoration potential for mammals. Consequently, we provide a robust quantitative framework to prioritize degraded forest restoration based on biodiversity considerations. Tropical forest ecosystems are facing unprecedented levels of degradation, severely compromising habitat suitability for wildlife. Despite the fundamental role biodiversity plays in forest regeneration, identifying and prioritizing degraded forests for restoration or conservation, based on their wildlife value, remains a significant challenge. Efforts to characterize habitat selection are also weakened by simple classifications of human-modified tropical forests as intact vs. degraded, which ignore the influence that three-dimensional (3D) forest structure may have on species distributions. Here, we develop a framework to identify conservation and restoration opportunities across logged forests in Borneo. We couple high-resolution airborne light detection and ranging (LiDAR) and camera trap data to characterize the response of a tropical mammal community to changes in 3D forest structure across a degradation gradient. Mammals were most responsive to covariates that accounted explicitly for the vertical and horizontal characteristics of the forest and actively selected structurally complex environments comprising tall canopies, increased plant area index throughout the vertical column, and the availability of a greater diversity of niches. We show that mammals are sensitive to structural simplification through disturbance, emphasizing the importance of maintaining and enhancing structurally intact forests. By calculating occurrence thresholds of species in response to forest structural change, we identify areas of degraded forest that would provide maximum benefit for multiple high-conservation value species if restored. The study demonstrates the advantages of using LiDAR to map forest structure, rather than relying on overly simplistic classifications of human-modified tropical forests, for prioritizing regions for restoration.
