Kurz, a tropical peat swamp forest timber species through tissue culture technique - Review Abstract: 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 a relatively shorter time for forest rehabilitation and enrichment planting purposes.

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 second growing period, seedling mortality occurred (17%) already with the thinnest ash mulch. The results suggest that ash mulch around seedlings in quantities of less than 0.5 cm (or 7 kg.m-2) is feasible and is not detrimental to Scots pine seedlings. The results provide foundation for further field research on the longer-term impacts of wood ash mulch on planted seedlings on boreal forest sites and on the feasibility testing of the mulch as a supplement to or substitute for the soil preparation for seedling planting.

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 different spatial patterns. The modified method was superior to other combinations of methods in terms of relative bias and relative efficiency. Considering statistical and practical aspects of sampling for tree density, the modified method is more promising than is the standard one.

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 accumulated in stands of both forest-forming species aged 41-60 years. The models are made on a dependence of carbon allocation in the different components of aboveground biomass by age. Results of energy content in the aboveground biomass were presented in Scots pine and black locust stands within the surveyed area. The study has shown that the energy potential of carbon accumulated in the biomass of Scots pine stands amounted to 40.31 PJ, and that of black locust stands was 32.04 PJ. Development of forest ecosystems in the Steppe zone of Ukraine can result in the optimization of abiotic conditions on a local level under the influence of the global climate changes.

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 with respect to unit, batch and shift times was conducted. The average duration of a harvester's work shift was 623 min, out of which operational time amounted to 73.6%. In forwarders the average shift took 520 min, with operational time representing 71.2%. In the course of the analysis and statistical data processing, all the remaining shift times which constitute an average harvester and forwarder work shift were quantified in detail. Work shift utilization ranged from 86.1 to 95.3%.

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 growers enrolled and 43 not enrolled in the Consortium of "Marrone del Mugello Protected Geographical Indication") to highlight the relationships between farmers and institutional actors. The network of the Consortium members was compared with the network of the non-members. The results show that a well-structured network allows for better dissemination of information and knowledge between farmers and greater diversification of product market sales.
