The Northwestern Ontario Forest Ecosystem Classification NWO FEC is an ecologically based forest site classification system for northwestern Ontario Canada. This article provides examples which show how the NWO FEC system has been applied for the purposes of ecological description at both the stand eg 10 ha size and landscape eg 1 20 000 mapping scale levels. At a stand level the NWO FEC can be used to examine species autecologies soil moisture requirements and wildlife habitat preferences. At a landscape level the NWO FEC system is employed to construct landform toposequences correlate interpreted climatic features with forest humus forms and develop spatial models of ecosystem processes. In the future classification systems such as the NWO FEC will be used for advanced simulation modelling problems at various spatial scales. boreal forest Ontario forest site classification I ecosystem modelling Resume Applications d une classification des écosystèmes forestiers au niveau du peu-plement et de I unite de paysage dans le nord-ouest de I Ontario Canada. Les classifications des stations forestieres sont des outils utilises pour atteindre divers objectifs d amenagement et de pla-nification des ressources et servant de cadre pour aborder les questions de biodiversité et de déve-loppement durable.
