Abstract:	The paper presents the dynamics of the carabid populations identified in a mixed tree forest on a period of 2 years (2006-2007), from April till October. The mixed tree forest is located in  Bistrita Gorges, in the western part of the Buila-VI!nturarita National Park. Within the forest I  have identified 19 carabid species belonging to 6 genera, 12 species were common, being captured  in 2006 and 2007. The studied populations were characterized by a small number of eudominant  species: 4 eudominant carabid species and 2 dominant ones in 2006 and 4 eudominant carabid species and 3 dominant ones in 2007. The majority of the identified species belonged to the accidentally class specie, having low frequency values in samplings. The species diversity of the carabid populations from the mixed tree forest varied widely throughout the years, influenced by the abiotic factors. The quantitative and qualitative composition of the carabid populations was determined: number, seasonaldynamics, mean individual biomass, Shannon-Wiener index of diversity.
