Milieukartering provincie Utrecht – Presentatie van de floristische gegevens met behulp van een computer

This article discusses the environmental mapping project of the province of Utrecht. A survey is given of the possibilities of setting up and using a databank of floral investigations. A description is given of the various possibilities of sorting out the data in tables (fig. 1—6), in distribution maps of species (fig. 7—8), etc. The necessity of getting a better knowledge of the autecology of plants is evident. The main cost of setting up a databank is caused by the field inventory. Costs of programming, computer input and output are marginal.
