Abstract

This report discusses a conceptual model for the vegetaiton (MOVE), that predicts on a national scale the possibility that plant species will (dis)appear in the year 2015 in perspective of national scenario's for acidification, eutrofication and dessiccation. The model combines existing models for abiotic environmental conditions and information on the ecological tolerance of individual species by means of a risk assessment approach. Important features of the conceptual model are: a national scope, use of risk-assessment, applicable for both common and more rare plant species and multiple stress. Results can be visualised in a so-called AMOEBE figure. MOVE can be used for scenario studies that support the State of the Environment documents.
