The frequency and intensity of typhoons are expected to increase over time due to climate change, and forests must be resilient to bear their effects without substantial ecological shifts. It has been suggested that post-windthrow management should focus on cool-temperate and boreal forests, where forest recovery may be slow and sensitive. Here, our aims were 1) to quantify forest recovery 30 years after windthrow by using four forest indicators (tree height, stem density, forest cover ratio, and LAI) estimated from aerial imagery and LiDAR data, 2) to compare the indicators between unmanaged and variously managed (salvage logging, scarification, sowing, and planting) stands, and 3) to determine the factors affecting forest recovery. Ordination results indicated that even 30 years after windthrow, stands were still at the initiation stage, and post-management activities delayed recovery, especially in terms of tree height. Regression models provided additional evidence of the negative effect of management activities on stand recovery and identified elevation, aspect, and pre-disturbance stand attributes as important drivers of recovery following windthrow. Our results suggested that natural succession may be the path to achieving high resilient systems after windthrow, and the intensity of post-disturbance management should be carefully considered based on pre-disturbance stand attributes and local topography.
