Abstract [en]

In this paper, we present a method for base-line mapping of biotope and landscape elements in the rural Swedish agricultural landscape. The overall goal is to elaborate a classification system for a national landscape monitoring program, based on interpretation of existing colour infrared (CIR) aerial photographs at the scale 1:30000, and including a field control. The classification system developed was tested by mapping landscape elements in strategically selected test areas, and it is assessed with respect to interpretation accuracy. The landscape elements, mapped separately as patches, lines and points, are significant for the biodiversity on landscape level, and are susceptible to change. The classification system is based on a hierarchical approach in five levels, with regard to land use and management, nature type and succession stage, moisture, physiognomy, vegetation cover and plant species. By using the method and the suggested classification system, a base-line mapping can be done very quickly and accurately. The mapping rate is 1.4-2.8 km(2)/h and the interpretation accuracy is 95-99%.
