The main problem with firewood production is the same as for other wood biofuels: storage. Usually, firewood is stored in logwood. The goal of this study was to determine the drying storage dynamics of logwood used for firewood production under the typical forest practice of southern Europe. Storage dynamics were evaluated for two different tree species (poplar and black locust) with logwood disposed in uncovered piles for a period of 180 days (March-September). In this study, the effect of the diameter of logs and their position inside the pile on wood drying was evaluated. This evaluation was performed considering the main key drying physical parameters - temperature (T), moisture content (MC), heating value (HV) and dry matter (DM). The study found that initial values of key parameters were different for both forestry species, but at the end of the storage period the values were considered to be similar. No statistically significant differences were pointed out between logs with different diameter sizes and different positions in the pile. For this reason, drying logwood in uncovered piles can be considered a good storage method irrespective of forestry species, the diameter of logs and the position of logs in the pile.
