This paper suggests that for assessment studies, divisions into a core region (ecoseries), an im- mediate surrounding (ecosecction) and a wider surrounding ( ecodistrict) should be used in eco- system classification. A methodology to classify sites was set up and, making use of ten sites for biological evaluation in Belgium, it was shown how a hierarchical ecosystem classification could improve categorisation. Often the visual characteristics of the surrounding landscape, such as diversity or connectivity, mask the fea- tures ofthe core zone itself(ecoseries). Using different hierarchic ecosystem levels is a direct and effective help to avoid this masking and to give more importance to existing nuances.
