Abstract: Reconstructing and quantifying human impact is an important step to understand how, when and to
what extent humans have changed the landscape during the Holocene. In this study we present a
reconstruction of vegetation changes throughout the Holocene based on palynological data of six study
sites in the Dijle catchment, located in the Belgian loess belt. A reconstruction of human impact in the
catchment is extracted from the palynological study based on statistical analyses (cluster analysis and
non-metric multidimensional scaling (NMDS)). The NMDS analysis on the pollen data do not detect
large-scale Mesolithic or Neolithic human activities on the Dijle catchment. In these periods, human
impact in the catchment was probably limited to local disturbances and small-scale forest clearances.
Only from the Bronze Age onwards (ca 3900 cal a BP) human impact was clearly detected in the pollen
records and vegetation gradually changed. Human impact further increased from the Iron Age onwards,
except for a temporary halt between ca 1900 and 1600 cal a BP, possibly coupled with the Migration
Period in Europe. The general vegetation development and increasing human impact are rather similar at
the catchment scale, beside some local variations in timing and intensity of the human impact in the
different subcatchments. The applied methodology, cluster analysis and NMDS, proves to be a useful tool
to provide semi-quantitative insights in the temporal and spatial vegetation changes related to
increasing human impact.
