Quercus cerris is an important species in the forests of Kosovo with a potential high economic value, although there is little information on the stem quality for the saw-milling industry. This study brings data on wood properties, particularly on heartwood, sapwood and bark development within Q. cerris trees grown in two sites in Kosovo, where mature trees were felled, and discs taken at different stem height levels. The average radial growth rate was 1.21 and 1.76 mm yr-1 for both sites. Heartwood decreased from the tree base upwards with a proportion of 53% and 43% until 5 m of height in the two sites. The radial width of sapwood was higher at the stem base (on average 44 mm) and afterwards approximately constant at 32 mm. The taper was low at an average 3.3 mm m-1 between 3.3 and 7.3 m of height. Bark represented on average 16.4% of the total stem cross-section and contained a substantial proportion of rhytidome (51% of the total bark area proportion at stem base and 41% at 9.3 m). Q. cerris in Kosovo showed good potential as a timber species for the supply of stem wood to the saw-milling industry, allowing good yields of heartwood-only sawn wood components. The bark should also be considered for complementary valorization.
