The activity of soil enzymes depended on a season of the year and altitude. The abundance of the Gamasida population was higher closer to the tree. Abundance and species composition of the investigated Gamasida population changed with season of the year, altitude, and distance from the trunk, however, it was not significantly affected by the activity of the enzymes.
