Fig. 5

Total cover ratio by height class for each species or group of species in the Spanish and Portuguese NFIs. Continuous line corresponds to unburned plots whereas dotted line corresponds to plots that were later burned (a conifers species, b oak species, c other species). The seven height classes are distinguished as follows: h1 > 16 m, h2 [8–16 m[, h3 [4–8 m[, h4 [2–4 m[, h5 [1–2 m[, h6 [0.5–1 m[ and h7 < 0.5 m
