Earthworm middens and non-midden soil were sampled for microarthropods in a mowed recreational field and and adjacent woodlot site. Samples were taken in fall 1983 and spring 1984. The earthworm middens of the mowed field supported a higher density of micrarthropods (especially Collembola and prostigmatid mites) than adjacent non-midden soil. This positive midden effect in the mowed field was more pronounced in the fall than in the spring. Woodlot earthworm middens examined in the fall had lower densities of microarthropods (especially oribatid mites) than adjacent non-midden soi, but in the spring woodlot middens supported greater densities of microarthropods (especially Collembola) than adjacent, non-midden soil.
