dcterms:description
We observed the long-term effect of management (two thinning regimes: 2a – by positive selection from above and 3b – by negative selection from below compared to 1c – unthinned control) on production characteristics and forest-floor status in the stands of Scots pine in Central Bohemia (Czech Republic). We found similar effect of treatment on production during the 45-year long period of investigation, i.e. lower periodic basal area increment of both thinned stands compared to control. About 6-9 thousand kg of dry-mass was stored per hectare in humus horizon L in the stands studied in 2008, with insignificant differences among the variants. In horizon F, we found about 14-18 thousand kg of dry-mass per jhectare and differences among variants were again insignificant. Significantly higher amount of dry-mass was observed in horizon H in control unthinned plot compared to both variants with thinning (103, 45 and 60 thousand kg per ha in variants 1c, 2a and 3b, respectively). The results obtained indicate that studied thinning regimes resulted in significantly decreased amount of accumulated humus in forest-floor and consequently carbon and nitrogen under treated pine stands.
