Low consumer-grade cameras attached to small unmanned aerial vehicles (UAV) can easily acquire high spatial resolution images, leading to convenient forest monitoring at small-scales for forest manage...
Modeling Tree Growth Responses to Climate Change: A Case Study in Natural Deciduous Mountain Forests
biotic and abiotic factors climate change Hyrcanian Forest machine learning RCP scenarios
2023/11/22
Climate change has significant effects on forest ecosystems around the world. Since tree diameter increment determines forest volume increment and ultimately forest production, an accurate estimate of...
Age-independent diameter increment models for mixed mountain forests
Age-independent growth equations Algebraic difference approach Mixed effects models Uneven-aged forest Mixed species forests Growth index
2023/11/20
Mixed mountain forests with an uneven-aged structure are characterized by a high tree-growth?variability making traditional age-dependent?growth?models inapplicable. Estimating site productivity is ye...
Provision of ecosystem services in mountain forests–case study of experts’and stakeholders’perceptions from Slovakia
ARANGE project Western Carpathians context analysis participation societal demands
2016/9/2
Forests in the mountain ranges are supposed to meet multiple objectives at the same time. There are different expectations and priorities among stakeholder groups. The object of the research is the ca...
Evaluating the effects of physiographic parameters on the road cross section in mountain forests (Case study: northern forests of Iran)
hillside slope rock base soil texture
2016/1/29
Road cross section, as one the main effective factors in relation to fill and cut volume, was effective in costs and disturbance of forest road constructions. In this research, the effect of a few phy...
Influence of micro-relief and weed competition on natural regeneration of mountain forests in the Šumava Mountains
Czech Republic micro-relief mountain forests natural regeneration weed competition
2015/3/19
Natural regeneration and its relationship to micro-relief and weed competition were studied on 6 research plots in mountain spruce forests in the Šumava Mountains. The data on density regeneratio...
Regional analysis of climate change impact on Norway spruce (Picea abies L. Karst.) growth in Slovak mountain forests

2015/3/3
The paper presents the results of a regional analysis of climate change impacts on Norway spruce growth
in the north-western part of Slovakia (Orava region). Radial increment was determined from nin...
Research on principles of making access to mountain forests by forest road networki

We consider making access to forests and forest complexes as an optimal allocation of routes of forest roads, land and air communications and transport routes with their optimal structure (composition...
Sustainable management of mountain forests in the Czech Republic
Czech Republic mountain forest sustainable management
2015/2/2
Forest management in the Czech Republic (CR) was not shaped in the environment of natural forests but in the territory that was influenced by unregulated felling and animal grazing for a long time. He...
Introskeletal erosion threat in mountain forests of the Czech Republic

2015/1/29
Summarization of the potential of introskeletal erosion (ISE) was done on the basis of field surveys in the Šumava Mts., Krkonoše Mts. and Jeseníky Mts. areas. The results give a rough estim...
