Figure 3


Principal Components Analysis of bryophyte parameters (biomass and species richness), forest age, basal area total and of each host tree species, tree density and percentage of each tree zone covered by bryophytes. Each symbol represents the combination of bryophyte statistics and environmental variables at the plot level. Forest age class represented by symbols: Circles = (8 YAH); squares = (15 YAH); diamonds = (25 YAH); rectangles = (60 YAH). Host tree species labelled by colours and letters: E = Erica arborea (grey symbols); L = Laurus novocanariensis (empty symbols); M = Myrica faya (black symbols). For more detail about bryophyte parameters see Table III.
