Assessment fre data and rather large spatial units. Hence, generalizations of particular habitat features are unavoidable. Nevertheless, we do not assume that every part of a given habitat type is of equal value with regard to its capacity to provide ecosystem services, social values or management practices. This kind of information is planned to be generated during future applications. After that, results are expected to provide statistical and spatial information and illustrations (maps) which are useful for landscape planning and environmental management. Conceptual models and, in particular, spatially explicit information, like maps, have a high potential to support the understanding of complex systems and interrelationships
