Abstract
<p>Restoring forests has recently received considerable attention as an effective tool to address societal challenges such as climate change and biodiversity loss. Shiretoko National Park in northern Japan is currently undergoing restoration to pristine natural vegetation, consisting mainly of mixed conifer-hardwood forests, based on scientific knowledge and an adaptive-management approach. In this study, we assessed this forest-restoration effort in terms of forest-canopy structure using aerial light detection and ranging (LiDAR) data and aerial imagery data collected by an unmanned aerial vehicle (UAV). Specifically, we evaluated forest height and structural diversity in both native and non-native plantations, and assessed forest growth for five major forest types, such as primary and secondary forests, during the 16-year period 2004-2020. We found that forest growth tended to be higher in native-tree plantations than in other forest types. By contrast, the structural diversity of native-tree plantations showed slow recovery toward natural forests. Our findings indicate that structural diversity has not fully recovered after approximately 40 years of restoration. We also describe the restoration activities conducted in Shiretoko National Park based on adaptive management, and discuss a potential framework for determining optimal reforestation approaches. We anticipate that these findings will be useful for ecosystem-restoration planning in other regions.</p>
