Gonystylus bancanus (Miquel) Kurz is one of the most valuable timber species in tropical peat swamp forest. Its timber is widely used for furniture, decorative cabinets and interior decoration. Due to its higher demand, G. bancanus continues to be harvested which leads to its disappearance in the wild. This is worsened by the fact that germination rates in the wild are very poor due to rapid insect and fungal infestation. Even though vegetative propagation via stem cuttings has been successful, proper protocols on tissue culture need to be explored as a viable way of mass production of a large number of planting stock in...

Wood ash production from power plants and the use of recycled ash for earthworks and forest peatland fertilization have increased markedly in Finland in recent decades. In this study, effects of wood-based ash on potted Scots pine seedlings were tested in a greenhouse. Seedlings were grown for one to two growing periods in peat with ash mulch thicknesses 0-8 cm. Seedlings grew well in ash thicknesses 0-4 cm during the first growing period. Seedling mortality (60%) occurred with the thickest ash mulch. Soluble nutrients in press water extracts were high compared with the control treatment. N and P levels were suboptimal also with ash mulch. During the...
Adaptive k-tree sample plot for the estimation of stem density: An empirical approachOriginal Paper

Available budgets for the inventory of non-commercial woodlands are small. Therefore, there has been increased interest in using distance methods, such as k-tree sampling, which are faster than fixed plot sampling. In low-density woodlands, large search areas for k nearest trees contradict any practical advantage over sampling with fixed area plots. Here, a modification of a k-tree sample plot with an empirical approach to estimating the number of trees per unit area in low-density woodlands is presented. The standard and modified k-tree sample plots have been tested in one actual and three simulated forests with...

The study evaluated the energy potential of Scots pine and black locust stands within the Northern Steppe of Ukraine, in forest plantations subordinated to the State Agency of Forest Resources (Ukraine). This study defined general values of aboveground biomass components per age-class structure in the forest stands. Allocated carbon was calculated using the biomass components by age groups as follows: stem, branches and leaves (needles). Contribution of different age groups to carbon allocation was investigated. A key role of stem wood in the process of carbon allocation in the forest stands was shown. It was found that the maximum carbon budget was...
Evaluation of total time consumption in harvester technology deployment in conditions of the forest sector of the Czech RepublicOriginal Paper

Cut-to-length technology represents a modern forest logging technology characterized by high performance, efficiency, productivity and work safety. At the same time it is friendly to forest ecosystems. Both acquisition and operating costs of harvester units are high, which requires their year-round utilization. The aim of this paper was to analyse shift time consumptions and thus analyse the common harvester and forwarder work shift. In 2015-2016 we collected time snapshots of harvesters and forwarders of various performance categories and from different production conditions throughout the Czech Republic. Consequently the analysis of work shift time...
Relationship between innovation and networks in chestnut value chain: A case study in ItalyOriginal Paper

In the last decades, the chestnut production has decreased in Italy due to diseases such as chestnut blight and chestnut gall wasp, and progressive depopulation of mountainous areas. The aim of the paper is to analyse the role of social network to enhance the dissemination of new ideas and innovations in view of the chestnut value chain development. The study was conducted in the Mugello-Val di Sieve area in the Tuscany region (Italy). A participatory value chain analysis approach was used for the strengthening of the local chestnut value chain. The data were collected by administering a questionnaire to a sample of 126 chestnut growers (83 chestnut...
