Fig. 6

Location of each woody species, herbaceous vegetation, and burn severity categories (low severity, moderate severity, high severity, unburned in the last 10 years (young vegetation), and unburned in the last 20 years (old vegetation)) in the plane defined by the first two axes of the correspondence analysis developed for the lowest stratum vegetation (0–0.5 m) in each ecosystem (a shrubland, b heathland, c broomland, and d oak woodland). L low severity, M moderate severity, H high severity, Y young vegetation, O old vegetation. Values in brackets correspond to the percentage of total variance explained by each axis. The average cover per burn severity category of each woody species and herbaceous vegetation in the 0–0.5-m stratum are shown in Additional file 3: Table 3.1
