Tree height is one of the most important variables in describing forest stand structure. However, due to difficulty in height measurement, especially in dense and mountainous forests, the common approach is to invoke the height-diameter (H-D) models. The oriental beech (Fagus orientalis Lipsky) is one of the most important species of Hyrcanian forests, over the mid to high-altitudes (400–1 800 m a.s.l.), in northern Iran. In this study, the H-D relationship of beech trees was investigated separately for mid-altitude and high-altitude in Shafaroud forests of Guilan using 14 nonlinear H-D models and an artificial neural network...

Forests cover almost one half of European land. Therefore, land taxes, including taxes from forests, are essential for a municipality's income. The land tax system is implemented on different levels, mainly nationally and locally. Therefore, many land tax features are settled by federal law, and others differ according to the local tax administrators. The objective of the paper is to compare the current laws and principles and the implementation process of forest land in Slovakia and Portugal. We have selected countries from different geographical areas of Europe. Even though the forest compositions and forest ownership differ, we aimed to identify...

Land abandonment and the emergence of new forest areas create novel dynamics for forest ecosystems and landscapes. Modelling is often used to forecast tree species composition, age group distribution and spatial patterns in the future. The aim of this study was to develop three scenarios for changes in tree species composition, stand age distribution and spatial patterns of new forest areas and permanent forests using Latvia as a case study. We selected 19 study areas of the size 10 km × 10 km to sample the variety of forest cover patterns, tree species, and stand age. Using GIS tools, we developed three scenarios: baseline, commercial...
Forest as a source of renewable material to reduce the environmental impact of buildingsOriginal Paper

Construction sector has high environmental impact throughout entire life cycle of buildings. One way to reduce the impact is to use building materials with the lowest possible environmental impact – such as wood. The use of wood-based building materials can improve the overall environmental balance of buildings. Compared to other materials, wood probably has the best environmental performance. These findings are particularly significant in the context of the environmental and legislative situation in Europe and the Czech Republic and may be one of the reasons for the increasing number of new wood-based buildings. The main reason for the...
