Table III
Total bryophyte biomass (kg/ha), cover (percentage of cover/25 m2) and species richness (number of species/25 m2) through the chronosequence. The stratification system is considered for each host tree species, separately. The highest value for each tree zone is shown in bold and dashes indicate value of zero.
