Earthworms are invertebrates from phylum Annelida, class Clitellata, subclass Oligichaeta. Through their activities, they help to maintain the soil structure and the process of bioturbation or movement of materials in soil layers. Although they are not quantitatively the most abundant organisms in the soil, their size and impact on the soil make them important factors in the overall soil biomass. The aim of this study was to determine the qualitative and quantitative composition of lumbricofauna in the area of Požeška gora. During 2020, a total of 82 sites were surveyed, and a total of 747 individuals were sampled. The presence of 15 species was established, which are classified into 10 genera. According to the quantitative composition, the most represented genus is the genus Aporrectodea with 469 individuals, within which the species Aporrectodea rosea with 236 individuals and Aporrectodea caliginosa with 219 individuals stand out. Qualitatively, the most represented genus is the genus Octodrilus with 3 species: Octodrilus croaticus, Octodrilus lissaensis and Octodrilus transpadanus. The average number of earthworms per m2 is 36 individuals.
