- Abstract in English : The Cranberry fritillary (Boloria aquilonaris) is a typical species of small raised bogs with mesotrophic influences. Its critically endangered status has prompted a species protection plan. This paper identifies its main habitat requirements as a sufficient area of peat bog, a high proportion of a micro-mosaic of mounds and depressions, a high-cover of mound species such as the host plant Oxycoccus palustris and Andromeda polifolia, an abundant nectar source of Erica tetralix and a low encroachment of grasses. A practical habitat quality index explained 79% of habitat occupancy. The main threats consist of desiccation, eutrophication, habitat fragmentation and ongoing succession. Solutions can be found in the creation of buffer zones between nature reserves and agricultural areas, restoration of degenerated bogs and small-scale peat cutting to set back succession. Conservation measures should be combined with adequate monitoring as a basis for adaptive management. It is argued that a species-based approach can be combined successfully with a system approach to achieve the conservation of entire ecosystems.
