The paper presents the assessment of compaction grade caused by machinery used in forest biomass for energy harvesting. The main aim was to determinate unaffected soil conditions, the compaction grade exactly after harvesting activities, the return of soil after couple of years and compaction grade in stands, which were not harvested but affected by skidding and seed collection activities. Therefore four different compaction grades were evaluated. To ensure as much as possible uniform soil conditions also soil samples were evaluated. Soil samples were collected using Kopecky physical metal rings and followed characteristics of soil were determined i.e. moisture content, bulk density and porosity, respectively. In San Rossore national park 24 plots were identified of which 8 were harvested in 2011 year (H2011), 8 were harvested in 2005 year (H2005), 7 were not harvested but were affected by other activities (NH) and 1 was unaffected (U). On each plot 50 repetition of measurement were carried out. The results display both: significantly different compaction grade of soil and return of the soil towards the original conditions after 6 years.
