Design of the permanent plots. a Dendrometric variables for individual trees are measured on a plot sized 250 m2, here indicated in grey, while landscape- and stand-level variables, and biodiversity habitats are recorded on larger plots of 0.1 and 0.2 ha, respectively. b Tree densities and tree heights in young stands are measured on five 16 m2 subplots (dotted circles). c Four subplots are used to assess cover of bilberry and lingonberry (black squares), and for recording the number of trees with dbh < 5 cm and browsing intensity (dotted circles). d Patches of droppings from moose and red deer are counted on a 100 m2 plot (dark grey), while downed deadwood is measured along perpendicular transects of length 18 m (thick dotted lines)
