The quality of the soil is one of the three components of the quality of the environment, together with the quality of water and air. Soil quality indicators are divided into physical, chemical and biological soil quality parameters. As a biological soil quality parameter, soil animals have been determined as an important measure due to their rapid reactions to anthropogenic deterioration. One of the indicators designed and developed in recent years in determining the biological quality of the soil is QBS-ar. The QBS-ar index focuses on the presence of morphological characters that show micro-eclamps adaptations to the soil ecosystem and does not require complex taxonomic identification at species level.   Seven different trees (Abies cilicica Carr., A. nordmanniana ssp. by Bornmülleriana Mattf. and A. Nordmanniana ssp. The QBS-ar values determined by the Nordmanniana Mattf., Pinus sylvestris, Pinus nigra Arnold and Quercus petraea L. and Fagus orientalis L.) have found statistical differences both by time and by tree species. The lowest QBS-ar value was found in Abies cilicica (66) and the highest value was found in Pinus sylvestris (91). As a result, QBS-ar has shown that the soil has different biological quality under different trees.
