This method can be used for state of the (ecological) environment reporting. The following issues are discussed: policy needs, current ecological yardsticks, indicator selection, resolution, aggregation of information, presentation of results, ecological models and ecological monitoring programmes. On the basis of this information the conceptual method is proposed at a regional level using target species, ecosystem species and abiotic conditions of target species and target ecosystems. Needs to work out this conceptual method are discussed in terms of research and compared with current reserach programmes of the RIVM and the IKC-NBLF. Ommisions and cornerstones have been identified.60 pnl12ecosysteemanalysemethodebio-indicatorecosystemsanalytical methodsbioindicatorsamoebaecologische indicatorenamoebenonderzoeksprogrammering; natuurtoekomstverkenningenmilieutoekomstverkenningenReport2012-12-12
