Each region was characterised by a special combination of parameters or landscape components. Considering inventory data from a chosen area (Figure 3: P), the components found there can be compared with the characteristic components of the region where the area is situated (Figure 3: 1). In the same way the components of the chosen area can be compared with the components of other areas (Figure 3: 3 and 4) and also with those of neighbouring regions (Figure 3: 2). Figure 3: Evaluation of the representativity of the landscape components in a planning area using physiographical regions. Examples of different ways (1-4) to relate the landscape components in the planning area. This makes it possible to analyse the appearance of components within an area with respect to representative natural features (components of the area/components of the region) together with frequency and pattern (diversity, rarity). Repeating this analysis at different points in time provides a picture of changes in the environment and can be useful for monitoring changes in landscape components. The next step in the improvement of the evaluation method was to stress the importance of vegetation and vegetation types and to obtain more or less complete lists of the vegetation types within the regions. In this way, it was also possible to use the physiographic map as a flexible biogeographic map. Knowledge of vegetation types is not only useful for identifying the habitats of plant and animal species, but is also useful for inferring abiotic factors such as climate and soil conditions.

types, in conjunction with ecological studies, can be used both to analyse the functions of ecosystems separately or together as a landscape ecosystem. A compilation of the knowledge on Nordic vegetation was made and published in the report “Vegetation types of the Nordic countries” (PÅHLSSON 1998). Each unit was briefly described under the headings area, physiognomy, soil conditions, climate, characteristic species, number of species, stability, land use-management and references. The name of the unit was given in Latin but also in the Nordic languages and English. This material was later adapted for electronic database format. In 1999, the database “European Vegetation Types, The Nordic Countries” was published on CD-ROM and in 2000 on the Internet (PÅHLSSON 2000). This database has been instrumental in the classification of inventory data and also as a tool for rapid analysis of Nordic vegetation types and their relationship to different factors and (physiographic) regions.
