Abstract
The soil-zoological research took place in 2018 on the territory of the soil-hydromeliorative station “Malinovsky” of Lisinsky educational-experimental forest farm (Tosnensky district, Leningrad region, Russia) which was drained in 1973-1974. The purpose of this research is a comparative evaluation of the density of the population and taxonometric variety of eco-functional groups of macrofauna on the Gleysols Histic Drainic after 45 year draining period and the similar biotop without drainage. The constitution of group and species and the trophic structure of soil macrofauna have been researched. 118 individuals of geobionts out of 3 types and 6 classes have been collected. It’s been stated that zoophages are the trophic dominating group. After 45 year draining period a poor groups and species constitution, a low number of large soil invertebrates and a small share of saprophages have survived which corresponds to the fauna of the soil in oligotrophic bogs.
