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. |
