 The assessment of ES can be carried out in different levels of detailedness and technical complexity. A common approach is to classify these approaches into 3 different “tiers”. They provide a rough orientation on the assessment characteristic with transitional versions being possible (Grêt-Regamey et al. 2017; Maes et al. 2014) ((Grêt-Regamey, A.; Weibel, B.; Rabe, S.-E. & Burkhard, B. (2017): A tiered approach for ecosystem services mapping. In: Burkhard, B. & Maes, J. (Hg.): Mapping Ecosystem Services. Sofia: Pensoft Publishers, p. 213–217.))

   * Tier 1: The most basic approach assesses ES by using existing, widely available (large-scale) datasets (like CORINE for Europe) as a proxy for the provision of certain ES. Most ES indicators on this tier can be served using land use and land-cover data, biodiversity monitoring maps, national forest inventories, etc. On this tier ES may also be scored by expert estimations based on simple cartographic representations or even without them. Therefore, the used indicators must be of direct dependency of specific ecosystems (or other mapped units), i.e. spatially explicit or area/size-based.   * Tier 1: The most basic approach assesses ES by using existing, widely available (large-scale) datasets (like CORINE for Europe) as a proxy for the provision of certain ES.
