Table 3 Mean pre- and post-treatment oak seedling densities (±1 standard deviation) from 2009 to 2018 among oak restoration sites 1, 2, and 3 on the southern Cumberland Plateau, Tennessee, USA. The P-values were estimated using a repeated measures analysis with a first-order ante-dependence covariance structure (with 95% confidence levels). At Site 1, oak seedling densities after the first fire were significantly different from the other time periods (P ≤ 0.05). All other comparisons were not significantly different
