The significance of soil texture in forestry, and its determination by a rapid field method. Jour. Forestry 35 (5): 503.
It is essential to have a reliable system to detect humans in close range of forestry machines to stop cutting or carrying operations to prohibit any harm to humans. Due to the lighting conditions and high occlusion from the vegetation, human detection using RGB cameras is difficult. This paper introduces two human detection methods in forestry environments using a thermal camera; one shape-dep...

Most forestry machines being produced today include a personal computer that monitors and controls the harvester head, and an information system that stores data on every action the driver or the machine performs. Information and communication technologies (ICTs) thus provide an opportunity to improve efficiency and competitiveness and possibly also opens up new ways of working for actors in th...

This paper elaborates on forestry aid as it has evolved in the past. Future directions are suggested, referring to short and midterm projects, as well as long-term programmes. Tree planting has worked in the past, and is...
Forestry plans have been influential on tree species and planting in different ways, regulating tree species diversity. Investigation of the changes in tree species diversity and preservation livestock sustainability by using forestry inventory can be an appropriate tool for decision makers in management. Indicators such as the Shannon Wiener and Simpson indices can be used to study the variati...
