摘要: Fifteen species of earthworm were collected from a reclaimed fen peat soil used for rough hay in County Offaly, Ireland. The most common Aporrectodea tuberculata, Allolobophora chlorotica, Eisenia rosea and Octolasion tyrtaeum. A. chlorotica E. formed significant association. total numbers earthworms by hand-sorting reached maximum 197.1 m−2. Compared with hand-sorting, formalin-expulsion was an inefficient sampling method species. Soil moisture varied within the study area. Total densities biomasses greater where drier. turgida, Satchellius mammale pink form more dry soils whilst O. tyrtaeum, Lumbricus rubellus green wet soils.
