Table 1. Number of trees in different categories (Usnea longissima present, newly established, disappeared, or if the tree had fallen to the ground), in 2012 compared to 2005/06, within study sites and whether the trees were influenced by the experimental selective loggings. The five last columns show forest stand level information. Sites with no logging are shaded.

a) Area of location of trees with U. longissima.
b) From Vestad (2008).
c) Mean size of trees ≥10 cm DBH. 44–75 trees were measured in each site. From Storaunet et al. (2008).
d) Parts of site E8 was not included in the 2012-inventory, since the stand had been exposed to wind throws and quite a few trees had died from drought.
