Tree diametric-species diversity is affected by human impact in old Scots pine dominated forest in boreal Fennoscandia
Background Forest structural and compositional variability is of fundamental importance for forest ecosystem functioning and species diversity. The purpose of this research was to examine how human impact has affected the compositional-structural diversity of mature pine-dominated boreal forest in b...
