Description:
Two field experiments, located in Central and Northern Sweden, were used to study the influence of standing volume on volume increment and ingrowth in uneven-aged Norway spruce (Picea abies (L.) Karst.) stands subjected to different thinnings. Each experiment had a 3x2 factorial block design with two replications. Treatments were thinning grade, removing about 45, 65, and 85% of pre-thinning basal area, and thinning type, removing the larger or the smaller trees, respectively. Each site also had two untreated control plots. Plot size was 0.25ha. Volume increment was 0.5-6.8m^3ha^-^1year^-^1 for the plots, and significantly positively (p<0.01) correlated with standing volume. Within treatment pairs, plots thinned from Above had consistently higher volume increment than plots thinned from Below. Ingrowth ranged from 3 to 33stemsha^-^1year^-^1, with an average of 14 and 21stemsha^-^1year^-^1 at the northern and southern site, respectively. At the southern site ingrowth was significantly negatively (p<0.01) correlated with standing volume, but not at the northern site. Mean annual mortality after thinning was 2 and 7stemsha^-^1year^-^1at the northern and southern site, respectively.
