Models have been developed to calculate the impact of different policy scenarios on nature in agricultural areas. These models treat abiotic/landscape factors and management regimes separately. First, separate maps are made of the quality of separate abiotic factors. These maps are then integrated into a single map, describing the ‘potential quality’ of the landscape. Management is considered as a factor that determines the degree in which this potential quality is realised, resulting in a ‘realised quality’ map. The potential and realised habitats are differentiated into reproduction habitats and foraging habitats. The final suitability of these habitats is determined by their magnitude and spatial distribution. A brief description is given of how the model can be used to calculate different scenarios. This may be done by making changes in the factor maps (e.g. changes in landscape structure or drainage) or in the management map (e.g. intensification of the management regime).
