Table 2 Pearson’s correlation coefficients between the regeneration cover (%) of main tree species, i.e., Pinus sylvestris (Pisy), Pinus pinaster (Pipi), and Quercus pyrenaica (Qupy), and the cover (%) of main understory species. Only significant correlations are shown (p < 0.05). Species codes in Fig. 1
