This research was conducted in three stands of different ... -
Xylogenesis and phloemogenesis of Norway spruce in different ages stands at middle altitudinal zone
(Výskumný ústav papiera a celulózy, Sekcia Slovenský drevársky výskumný ústav, 2020)This study aimed to determine the influence of the stand age and selected weather conditions on the cambial activity, xylem and phloem formation and their development. For the analysis, microcores were taken weekly from ... -
Multi-seasonal systematic camera-trapping reveals fluctuating densities and high turnover rates of Carpathian lynx on the western edge of its native range
(Nature Publishing Group, 2021)Camera-trapping and capture-recapture models are the most widely used tools for estimating densities of wild felids that have unique coat patterns, such as Eurasian lynx. However, studies dealing with this species are ... -
Overwinter Storage of European Beech and Norway Spruce Planting Stock: Effect of Different Methods and Temperature Conditions
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)The aim of this research was to compare methods of overwinter storage of forest tree species planting stock and to specify of the optimal and the minimal temperature for freezing. Planting stock of European beech and Norway ... -
Efficiency of Harvester with the Debarking Head at Logging in Spruce Stands Affected by Bark Beetle Outbreak
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)This paper deals with the use of debarking modifications of the conventional harvester head in the conditions of felling due to bark beetle calamity. For this purpose, a time study was established, in which the conventional ... -
Socioeconomic Impact of Mining in the Atiwa Forest Reserve of Ghana on Fringe Communities and the Achievement of SDGs: Analysis from the Residents' Perspective
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)The Atiwa forest reserve of Ghana sits upon roughly 150 million tons of bauxite. The Government has decided to mine and use the proceeds for national infrastructure development programs. This article examines the impact ... -
Surface charring of silver fir wood cladding using an enhanced traditional Japanese Yakisugi method
(North Carolina State University, 2022)The aim of this work was to better understand the ignition method of timber charring in order to improve the industrial process. Three silver fir boards were tied together to make a triangular prism, which acted as a ... -
Kolmogorovʼ entropy to investigate variation of forest soil properties in the Czech Republic
(Elsevier Science BV, 2022)A measure of variation in values of physico-chemical properties of different soil groups is influenced by deterministic uncertainty. In this study, we assessed variation level of soil horizon properties in the most wide-spread ... -
Effect of One-Sided Surface Charring of Beech Wood on Density Profile and Surface Wettability
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)One-sided surface charred European beech wood (Fagus sylvatica L.) was studied. Radial and tangential specimens of dimensions of 50 x 25 x 350 mm were one-sided surface charred at 200, 250, 300, 350, and 400 degrees C for ... -
Soil Microbial Functional Diversity under the Single-Season Influence of Traditional Forest Management in a Sessile Oak Forest of Central Europe
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)This one-year study focuses on the responses of a soil environment to the implementation of traditional forest management practices in oak-hornbeam stands with the following treatments: cut (C), cut + litter raking (CR), ... -
Description of Intra-Annual Changes in Cambial Activity and Differentiation of Secondary Conductive Tissues of Aesculus hippocastanum Trees Affected by the Leaf Miner Cameraria ohridella
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)Aesculus hippocastanum trees are commonly infested by the leaf miner Cameraria ohridella, whose larval activity causes the destruction of the leaf parenchyma and induces defoliation. Pest attacks result in, e.g., production ... -
Comparison of parametric and nonparametric methods for modeling height-diameter relationships
(Italian Society of Silviculture and Forest Ecology, 2017)This paper focuses on the problem of regionalization of the height-diameter model at the stand level. To this purpose, we selected two different modeling techniques. As a parametric method, we chose a linear mixed effects ... -
Predicted occurrence of ancient coppice woodlands in the Czech Republic
(Italian Society of Silviculture and Forest Ecology, 2017)Coppicing started in the Neolithic period and has been practiced throughout European history. This traditional silvicultural system was abandoned in many European countries during the 20th century. The Czech Republic now ... -
Willingness to Pay for Forest Existence Value and Sustainability
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)Uganda is richly endowed with flora and fauna. Until the early 2000s, most of the types of vegetation have remained natural/virgin forests and shrubs until recent years, when human activities have damaged them. Understanding ... -
