Fig. 2: Canopy complexity and annual phosphorus dry deposition along successional forest stages: agricultural field (Ag), 5- (5 yrs), 12- (12 yrs), 20- (20 yrs), and 60-year-old forest (60 yrs).

a Canopy height models show the deviation in canopy height (m) from the mean of a 40 × 40 m plot per successional stage. b Density distributions for three plots per successional stage displaying the deviation of mean height (DOMH, m) from the plot’s mean. c Canopy roughness and rugosity, based on unoccupied aerial vehicle-derived structure for motion and vegetation height, versus the annual P dry deposition. Points in (c) represent the plot-level measurements for annual P deposition and canopy roughness and rugosity.
