“…A similar approach was also used to estimate AGB and CS at stand level. The stand volume parameter was frequently selected as an indicator for the forest ecosystem's capability for timber production (Merganič, Marušák, Merganičová, Stolariková, & Tipmann, 2013;Irauschek, Rammer, & Lexer, 2017).…”

Stand density and species diversity are two indicators that are highly related to forest productivity. However, the effect of those variables on the productivity of community forest is rarely documented. This study evaluates the influence of stand density and species diversity on timber production and carbon stock in the community forest. The study area was located in Madiun District. A field survey was conducted in four different community forest sites, i.e. Morang, Kuwiran, Randualas, and Kare. The sampling technique was by quadrat method using a sample plot size of 25 m x 25 m. The number of sample plots used in this study was 64 units, which were evenly distributed in every site. Comparison of stand attributes among sites was examined by Kruskal-Wallis test and followed by Kruskal-Nemenyi test on the effects of stand density and species diversity on timber production and carbon stock were assessed separately for each parameter using the generalized least square regression test. The process of statistical analysis was applied using a significance level of 5%. Results show a significant difference in stand volume, aboveground biomass, and carbon stock among sites (P<0.05). This study also recorded a meaningful effect of stand density and species diversity on timber production and carbon stock of community forest, wherein stand density provided a higher effect (R2 = 0.68; P<0.05) than species diversity (R2 = 0.26; P<0.05).

“…Merganic et al (2016) found that, depending on the stage of stand development, forest biodiversity, structural diversity, and spatial heterogeneity can be positively related to timber quality in the Czech Republic. However, these relationships must be considered in the context of other factors that also impact timber quality.…”

“…This Special Issue is based on a technical session at the IUFRO 2014 World Congress that explored potentially positive interactions between high-value timber management and biodiversity. The papers cover a wide geographic range: from temperate forests in Europe (Löf et al 2016;Merganic et al 2016), Canada (Hébert et al 2016), and Japan (Owari et al 2016), to tropical forests in Cameroon (Doucet et al 2016) and Ghana (Onyakwelu & Olabiwonnu 2016;Stephens et al 2016).…”

Value production is one of the most important information for comparing different management strategies in forestry. Although the value production of forest stands is affected by various factors (stem and assortment quality, stem dimension, stem injury, price of assortments), thinning can be considered as one of the most important one. This paper aims at the evaluation of qualitative and value production in homogeneous beech stands, which were managed by two different thinning types for period of 45 to 55 years: (i) -heavy thinning from below (C grade according to the German forest research institutes released in 1902) and (ii) -Štefančík´s free-crown thinning. The third variant was control (iii) -subplot with no interventions. Silvicultural quality characteristics of the lower half of the stem were assessed using a 4-class scale (A -the best quality, D -the worst quality). Assortment structure (commercial quality) was estimated for each stem by an assortment model developed in the past. Nearly 3,000 individual trees aged from 83 to 105 years from 23 subplots established across the Slovakia territory were assessed. The highest volume of the best silvicultural quality of stems (A class) has been reached in forests where Štefančík´s free-crown thinning was applied (57 -85%) while the lowest (22 -56%) on subplots with no management. The proportion of two best commercial quality assortments (I + II) was highest in forests managed by heavy thinning from below (21 -29%) and the lowest when no treatment was applied (7 -19%). The highest value production (expressed in € ha −1 ) was reached in the forests treated by free-crown thinning. Results suggested the overall positive impact of thinning on the increase of value production in beech forests. Particularly, the free-crown thinning focusing on selection of best quality trees should be preferred as it leads, besides its sufficient value production, to a higher vertical differentiation of the beech forests.
