In this master’s thesis, we examined changes in moisture content and selected properties of Norway spruce (Picea abies (L.) Karst.) logs during storage at two different micro-locations. The study focused on logs stored at a sawmill facility in Nazarje, specifically in the immediate vicinity of the Savinja river and at a site approximately 200 m away from the river. Using sensors, we remotely monitored the influence of climatic conditions on the dynamics of wood moisture changes during the winter and spring periods. Before and after storage, we determined wood moisture content and gravimetric density, while changes in the dynamic mechanical properties of the logs were assessed using an ultrasonic method. We also investigated the properties of debarked and non-debarked sections of the logs. The results showed that climatic conditions differed between the two micro-locations and influenced the course of moisture changes in the logs. At the shaded location near the river, lower temperatures and higher relative humidity were measured, whereas the more distant, sun-exposed location provided more favourable conditions for wood drying. The gravimetrically determined wood moisture content decreased at both locations by the end of storage compared to the initial state. A comparison between debarked and non-debarked sections of the logs revealed differences in moisture change dynamics, mainly related to the protective role of the bark. Measurements of wood density before and after storage showed no significant changes, and the measured modulus of elasticity values indicate that storage during the observed period did not notably affect the mechanical properties of spruce logs.
