Europese en mondiale verspreiding van Nederlandse vaatplanten

Quantitative information about the distribution of plant species can play an important role in flora and vegetation analyses, for instance in relating distribution figures with floristic and phytosociological data. Therefore, all species of the Dutch flora were classified according to their distribution patterns in six more or less floristic homogeneous regions in Europe. For each region, the coverage of the plant species is given. The distribution outside Europe (but inside the Holarctic) and outside the Holarctic is qualitative. The figures are based on the natural distribution patterns of the species, except for those species that have been naturalized a long time ago and of which the original distribution is unknown (‘archaeophytes’). Apart from that, the position of the Netherlands with regard to the distribution area of the plant species is indicated.
