The aim of the research was a spatial and temporal analysis of the sale of large-size pine wood in Poland. The analysis was based on revenues from timber sales divided into WA0, WB0, WC0, WD and WK assortments. The source data was obtained from the State Forests Information System (SFIS) of 17 regional directorates of the State Forests for the years 2020–2022. The results obtained showed a differentiation in the structure of timber sales in the analyzed units. The study indicated an increase in the share of the WK assortment and a decrease in the share of WC0 in the total volume of large-sized timber sold. It was shown that during the study period the volume of sold assortments increased by 10%, with a very high increase in sales revenues – 78%. The research confirmed the large variation in revenues from the sale of large-sized pine timber between rdSF (WA0: v = 119.55%; WB0: v = 72.78%; WC0: v = 47.78%; WD: v = 101.04%; WK: v = 54.90%).
