)Arguments
- year

- perc_defol
An n-length numeric vector of the percent of trees experiencing defoliation.
- num_max_defol

- perc_max_defol
An n-length numeric vector of the percent of trees experiencing their maximum level of defoliation (i.e., their most extreme negative growth departure).
- mean_gsi
An n-length numeric vector of the average growth suppression index across all observed trees.
- mean_ngsi
