Leaf area index and soil water content responses to pre-commercial thinning in Norway spruce plantations under climate change

Popis výsledku v původním jazyce

Global climate change (GCC) and increasing drought frequency pose a threat to the stability of European forests, particularly those of Norway spruce [Picea abies (L.) Karst.] plantations. We investigated how different pre-commercial thinning (PCT) intensities affect leaf area index (LAI) and its relationship to soil water content (SWC) in young spruce stands in northeastern Czechia. Three permanent research plots in a 13-year-old monoculture were subjected to mild PCT, heavy PCT, or left as an unthinned control in winter 2019/2020. Thinning caused an immediate decrease in LAI, with averages of 8.3 +/- 1.1 m2 center dot m-2 (mild), 3.8 +/- 0.5 m2 center dot m-2 (heavy) and 11.1 +/- 1.1 m2 center dot m-2 (control) in 2020. By 2023, LAI in the mildly thinned stand had largely converged with the control, whereas the heavily thinned stand maintained significantly lower LAI. The strongest relationship between LAI and SWC occurred in the heavily thinned plot (R2 = 0.715 in 2021), while correlations were weak or transient in the mildly thinned and control plots. These results indicate that PCT intensity influences both the magnitude and duration of LAI reduction and is associated with differences in stand water dynamics. Appropriately adjusted thinning may therefore modestly affect water availability and could contribute to adaptive management of spruce forests under GCC.
