Palynological investigations were made up to know the vegetation history of the upper Nure Valley (Ligurian-Emilian Apennines). The reconstructed picture is in accordance with that already known for the northern Apennines. The pollen diagram relevant to the most significant palynological sequence (i.e. Pramollo sequence) shows a continuous range from the Boreal- Atlantic period to the lower Subatlantic one. Pramollo peaty sediments have been 14C dated and their age (380 cm depth) has been assessed at 5632±210 years B.P.
