This paper presents the species composition and number of epigeic carabid beetles (Col., Carabidae) inhabiting Redykajny Peatbog Nature Reserve (UTM DE65). The reserve is one of Europe’s largest forest complexes growing in town. Carabid beetles were captured in 2004–2005 at three sites in the nature reserve: on a margin of high bog, in a bog birchwood in the middle of Redykajny Reserve, and in a spruce wood, part of a humid mixed forest. Based on the quantity and quality composition of the populations of Carbidae, the authors made an attempt to evaluate the present state of the habitat. The results are at the same time the first inventory of epigeic Carabidae which occupy Redykajny Reserve.
