%X Site index (SI) curves for H 20 (dominant height at 20 years total age) were constructed for hybrid larch ( Larix ℅ eurolepis Henry) growing in 26 stands on former farmland in southern and central Sweden (Latitude 56每60∼ N.). The mean total age of the stands was 23 ㊣ 10 (range 17每49) years; the mean diameter at breast height (ob) was 16 (7每34) cm; the mean height was 14 (8每29) m; and the stands had a mean density of 993 (266每2195) stems ha ˋ1. A model derived by Cieszewski (2001) performed best for the data. The model explained 99% of the observed variation in height development. No apparent bias across the range of predicted site indices was found. SI was examined in relation to soil types. Multiple samples were available for three soil types: light clay, medium clay and till. There were no significant differences between these soil types with respect to the choice of SI curve.
