Growth characteristics of oak (Quercus petraea [Mattusch.] Liebl.) stand under different thinning regimes

Abstract

In the paper, selected quantitative characteristics of 57-year-old oak pole stage stand were analysed on plots with different thinning regimes at its establishment. Six thinning treatments were performed in an interval of 8, 14 and/or 5 years. We applied the method of target (crop) trees on three partial plots and method of promising trees on one plot with different intensity of releasing the trees of selective quality (promising and target trees). The results of both methods were compared with the control (untreated plots). Preliminary outcomes suggested that from the quantitative aspects the best results were obtained on plots where target trees were released by removing one and/or two trees at the stand age of 19 years. These results confirmed the well-known fact that the tending of young oak stands should be realized by thinnings of intermediate intensity.

Implications of Reduced Stand Density on Tree Growth and Drought Susceptibility: A Study of Three Species under Varying Climate

“…Our findings are in line with the general view that tree population density reductions result in accelerated tree growth and that the magnitude of growth increase is directly related to the intensity of the density reduction (e.g., [10]). Previous studies have also reported increasing diameter growth with thinning and reduced inter-individual competition in Scots pine [51,52,[95][96][97][98], sessile oak [18,99,100], and ponderosa pine [16,51,56,[101][102][103][104][105][106]. Stand density reductions can improve the growth of remaining trees by release from inter-individual competition for above and belowground resources, such as light, water, and nutrients [19,26,40], and are therefore often used as a silvicultural measure to maximize diameter growth and tree value on relatively short rotation [10].…”

At the same time, yield, defined as the entire stand biomass produced since stand establishment [107], might be lower under heavy compared with moderate stand density reductions or untreated controls [95,97,100,103], often prompting a trade-off between enhanced tree growth and stand productivity [26].…”
