Abstract:

High work consumption in forest operations is above all the result of the character and task realization mode in works undertaken in forestry. Development of mechanization in forest management activities allows to considerably decrease manpower needs. In the present study, there were analyzed the possibilities of reduction of work consumption by improving the mechanization level of forest works. The method was developed to consider the following assessments: 1) variant W1 – basic option comprising factual work consumption values in works carried out on the area administered by the Region

Abstract:

In Asian countries, people have a long history of using rice husk charcoal or wood ash as an agricultural soil amendment, but evidence of this has been long obscured. Since the 1980s, microbiological studies, mainly on symbiotic organisms, have been performed in Japan. Charcoal is a porous material with high water and air retention capacities and high alkalinity. Therefore, it stimulates root growth and enhances the infection of various symbiotic microbes to plant partners. The use of carbonised materials in agriculture, forestry, and construction will contribute to the sustainability of crop

Historically British Columbia's forests were managed under the implicit assumption that virtually the whole forested land base would, one day, be available for timber production. The BC Forest Service and licencees incorporate non-timber values into timber production plans through a process of "integrated resource management" which attempts to consider wildlife, riparian habitat, recreation, water flows, grazing and other forest uses in each decision about each hectare where logging is to occur. Under this extensive form of management, silvicultural investments are low. This policy has clearly

Insects constitute the largest single class of animals or plants in an ecosystem in terms of numbers of species.

The most significant of these in the context of the current Canadian emphasis, is that the forest ecosystem cannot be intelligently managed for sustained fibre production and species diversity without a better knowledge of the species and roles of the organ

Aromatic resins are valuable non-wood forest products (NWFPs) derived from Boswellia and Commiphora species in the drylands of this region. The study seeks to answer the following main questions: “What are the ecological and livelihood roles of resin producing species, and the role that people have in either degrading or restoring these ecosystems?” “Who are the participants in frankincense and myrrh production, processing, and trad

Analogue forestry involves blending traditional knowledge and science to recover and valorise indigenous knowledge, creating systems that are familiar to traditional societies and meet the needs of contemporary forest-dependent communities. Conservation agriculture is based the principles of minimal soil disturbance, permanent soil cover and crop rotations so as to achieve sustainable and profitable agriculture and improve farmers ‘livelihoods. Every farmer is a researcher, who experiments every season on his or her farm. Farmers who find something that works are likely to repeat it the next s

In this work, we present that how bifurcation in Pinus trees can influence productivity and harvester production costs. Our example draws from one harvesting machine that works in thinning operations in forest plantations of Pinus taeda L. in a small Brazilian forestry company. To get daily productivity, we use the machine’s system, which provides such daily information as total production. We also used a time and motion study to obtain the meantime to cut, delimb, and process the tree stem into logs. In this way, we separated the normal trees from the forked trees to get the operating cycle t

The objectives of this study were to characterize parent stand age and harvest method treatment effects on biomass production of aspen and other species, and to construct equations for the prediction of aspen stemwood, branch, and foliage biomass production. Aspen from young parent stands (30–40 years) generally regenerated taller and denser stands, and produced higher total aspen biomass and larger proportions of branch biomass than those regenerated from older parent stands. Stands regenerated after total biomass removal were taller and had larger diameters and average densities than stands

Abstract:

Recent concerns regarding non-timber forest product (NTFP) management are focused on raw material production. But NTFP ought to be viewed from the perspective of ecological processes, cultural heritage, livelihood of local people, economic values and incentives for forest management. This broader role for NTFP cannot be realised by simply domesticating a few species. Integration of NTFP in forest management is necessary in order to achieve sustainable forestry. Because forestry technologies are developed with timber values uppermost, it is vital to develop forest management technologies that t

Abstract:

Due to traditional forest management, the primary goal of which is the production of raw wood material, commercial forest stands are characterized by low biodiversity. At the same time, commercial forests make up the majority of forests in the Central European region, which means a significant impact on the biodiversity of the entire large region. Saproxylic species of organisms are a frequently used criterion of biodiversity in forests. Based upon the analysis of 155 scientific works, this paper defines the fundamental attributes of the active management supporting biodiversity as well as the

The production of short, wide tree crowns facilitates cone harvesting, supplemental mass or controlled pollination, and the control of insects and diseases.

Height, root-collar diameter, and oven-dry mass of tops and roots were significantly greater in greenhouse-cultivated seelings. However, the differences were reduced when the seedlings were sown later in the spring. Analysis of top-root ratios showed that the balance of seedlings was not affected by greenhouse cultivation.

Abstract:

The sustainable supply of timber is one of the most important forest ecosystem services and a decisive factor determining the long-term profitability of forest enterprises. If timber production is to be economically viable, there must always be a way to analyse forest stands and trees felled for exploitation with regard to the wood assortments they contain. Only then can the expected timber yields, achieved by various silvicultural strategies or actions and different sorting options, be quantified with sufficient accuracy. The SorSim assortment simulator was developed for forest practitioners
