  1. The percentage of ground returns (PCzero) was determined as the number of ground returns/(the number of ground returns + all above-ground returns).
  2. Values shown include the mean, with standard error in brackets, and the range. All LiDAR metrics are shown for data with a pulse density of 10 pulses m−2.
