Fire Ecology

Table 4 Pearson correlation coefficient (r) and its statistical significance (P) for plant cover (upper-right panel) and Pearson χ ² test (d.f. 1) for the presence/absence data of rooted plants (lower-left panel) in 0.5 × 0.5 quadrats (n = 600) between all five dominant species in a Cistus-Erica shrubland at Quintos de Mora (central Spain). Statistical significance (P ≤ 0.05) is marked in bold
