Earthworm populations in forestry plantations (Araucaria angustifolia, Pinus elliottii) and Native Atlantic forest in Southern Brazil compared using two sampling methods

•Earthworms were collected using handsorting and formalin extraction in three forest systems.•Handsorting was more efficient than formalin extraction in collecting earthworms, particularly endogeic species.•Formalin extraction collected mainly epi-endogeic species (Amynthas, Metaphire, Urobenus).•P. corethrurusabundance was higher in Pine plantations, A. gracilis in Araucaria plantations, A. corticis in native forest.•Earthworm population assessments and inventories in Brazilian forest systems should prioritize handsorting.
