The occurrence of thermophilous trees in the Scandes Mountains during the early Holocene: evidence for a diverse tree flora from macroscopic remains
1 Macroscopic remains of the fairly thermophilous tree species Alnus glutinosa , Tilia cordata and Betula pendula were recovered in subalpine and adjacent boreal environments far above and beyond their present‐day distributional limits. This establishes that the early Holocene tree flora of the Scan...
