The Holocene vegetation history in an area of northern Norway has been investigated by means of 12 pollen-analysed sections 11 of them from peat sediments. Biostratigraphical zonation of the individual pollen diagrams, and comparison between pairs of them have been carried out by numerical methods of the IGCP-158-b research programme. Generally, the zonation programme have adequate results. Zonation of the total pollen taxon assemblage including the peatforming taxa - and zonation of the regional pollen assemblage (trees), gave rather similar results. However, when studying man’s impact on vegetation, it might prove useful to exclude all peatforming taxa before running the zonation programme. The comparison programme proved not to give adequate treatment of this material, which is characterized by spectra with a high degree of similarity throughout the Holocene.
