The Lumbricidae family of brown forest soils in natural and agricultural ecosystems located in the central zones of the Republic of Moldova has been investigated in May, 2021 and 2022. Earthworms sampling was carried out from test cuts by manual sampling of soil layers to the depth of soil fauna occurrence. The number and biomass of Lumbricidae family in natural brown soils are greater by 3.8-17.9 times and by 2.6-16.5 times compared to brown soils of agricultural ecosystems. The highest values of abundance and biomass of earthworms were registered in the typical brown forest soils under natural vegetation and the smallest values - in arable luvic brown forest soils. A characteristic feature of the natural brown soils is the high concentration of invertebrates and Lumbricidae family in the upper layers of soils. The species Lumbricus terrestris, Lumbricus rubellus, Aporrectodea caliginosa and Aporrectodea longa and other were identified in the faunal samples from the natural brown forest soils.
