Table 7 Mean ± SE density (individuals per hectare) of (a) seedlings and (b) saplings of Scots pine, pubescent oak, and other species in each management treatment before (2014) and 7 years after the treatments (2021). F and p of each ANOVA test are indicated below the means. Abbreviations: control (CO), understory clearing (UC), understory clearing and pine thinning (UCPT), pine logging (PL). Different letters correspond to significant differences among treatments according to the post hoc Turkey test
