Wildfires are disturbances that open the canopy of the forest matrix and increase the heterogeneity of the environment. Their cause can be natural or anthropogenic. In August 2017, a wildfire engulfed the thermophilic beech forest (Seslerio autumnalis-Fagetum) on the southern slopes of the Northern Velebit National Park. Ground beetles (Coleoptera, Carabidae), as model organisms whose assemblages and species react to changes in the environment, were sampled using the pitfall trap method in the burned habitat and the unburned forest, as a control. A total of 37 species and 6267 individuals were collected. Although this research did not reveal significant changes in the biocenological parameters of the ground beetle assemblages (species richness, diversity and number of individuals) between burned and unburned forest, changes were detected at the level of dominant species, which shape the assemblages. Factors such as the size of burned habitats, soil structure, and proximity to forested areas play a key role in the speed of recovery of ground beetle assemblages after a fire. Furthermore, the absence of anthropogenic influence after a fire contributes to the faster recovery of communities. This research provides important insights into post-fire changes in ground beetle assemblages and suggests the need for further research.
