Table 6 Resistance, recovery, and resilience indices, calculated for a 3-year period for each silvicultural treatment in a dry year (either 1994 or 2017), before and after the treatment. Abbreviations: control (CO), understory clearing (UC), and understory clearing and pine thinning (UCPT). F and p of each ANOVA test are given. Different letters correspond to significant differences according to the post hoc Turkey test among treatments for each year (1994 and 2017), not across the different indexes
