| In the process of developing flora and vegetation statistics the CBS has collected a large number of data on autecological and other aspects of the vascular plants in the Netherlands. These data originate from various sources and have been brought together in one automated register, a botanical database containing information on the taxonomy, plant geography, morphology, autecology and vegetation of the species. Though primarily in aid of the statistical analysis of floristical and vegetative data, the register can also be used for external research and will be available, for a fee, on tape as well as in print. Continuous addition and improvement will enhance the usefulness of the information. The new subjects are added to the database in response to... |

| 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,... |
