From Nov. 1974 until Oct. 1975 soil samples were taken monthly in an oak-pine forest in West Berlin from 3 plots to investigate the influence of road construction and traffic on the moss mite population. Plot A is situated near a highly frequented road, thus affected by road construction, traffic and salt; plot B at a distance of 50 m in the forest (control plot), plot C near a macadam lane closed to all vehicles, thus only affected by road construction. The plots belong to the same forest stand, but differ somewhat in their pedological and vegetational aspects, because they are differently exposed to the road effects. Abundance of moss mites (and nearly all other mite and arthropod groups) is highest in plot A, lower in plot B and lowest in plot C; moss mite species diversity, however, is highest in plot B, lower in plot A and again lowest in plot C. Moss mite community structure is most similar between the plots A and B, less similar between the plots B and C, and least similar between the 2 roadside plots A and C; differences are partly due to a different depth distribution. Soil moisture and especially soil reaction (pH) are altered by road construction and salt application, but general correlations between these factors and varying moss mite abundances cannot be established (the same applies to soil temperature), probably due to the complex and partly indirect nature of the effects, e.g., via food availability.
