Popis:	Individual tree mortality was analysed for 9924 Scots pine trees from 26 pre-commercial thinning (PCT) experiments established in Sweden (57°–66° N) between 1953 and 1972. Almost all of the stands examined were naturally regenerated and homogenous pine stands. The PCT treatment factors included stand density and height at the time of PCT. The stand densities varied between 600 stems ha −1 and >9000 stems ha −1 before PCT. The height at the time of PCT varied between 1 and 8 m and mortality was examined 8.6–23.5 years after PCT. The results showed low overall mortality (
