In Europe, two commercially important treelike birch species occur naturally: silver (Betula pendula Roth) and downy pubescens Ehrh.). Both have a wide natural distribution area on the Eurasian continent, ranging from Atlantic to eastern Siberia. Although birches throughout almost whole of most abundant resources are in temperate boreal forests Northern Europe. Baltic Nordic countries, proportion out total volume growing stock varies between 11 28 per cent. is broadleaved tree species....

The boreal forests of Fennoscandia are largely dominated by Norway spruce and Scots pine. Conifer monocultures have been favoured in forest management during the last decades. Recently, concern has risen that consisting only one tree species could be vulnerable to biotic damage. Additionally, environmental societal changes placing new demands on utilization, thus shifting focus alternative options providing a wider scale ecosystem services. It proposed mixed better than with respect...

Models were developed for predicting the decomposition of dead wood main tree species in Finland, based on data collected from long-term thinning experiments southern and central Finland. The rates strongly related to number years after death. In contrast previous studies, which have used first-order exponential model, we found that rate was not constant. Therefore, Gompertz Chapman-Richard's functions fitted data. slow initial period mainly due fact most trees remained standing as snags...

The role of values in climate-related decision-making is a prominent theme climate communication research. present study examines whether forest professionals are more driven by than scientists are, and if this results value polarization. A questionnaire was designed to elicit assess the assigned expected effects change working on forests Europe. countries involved covered north-to-south west-to-east gradient across Europe, representing wide range bio-climatic conditions mix...

Self‐thinning models were developed to describe the relationship between stem number and mean diameter of even‐aged monospecific tree stands undergoing self‐thinning. The separately for Pinus sylvestris L., Picea abies (L.) Karst. Betula pendula Roth. stands. Data from 41 unthinned permanent sample plots used. According Reineke's equation —3/2 power rule self‐thinning, a log‐log plot average size density will give straight, self‐thinning line constant slope. this study, slope consistent with...

Forest management alters the growing conditions and thus further development of trees. However, quantitative assessment forest on tree growth has been demanding as methodologies for capturing changes comprehensively in space time have lacking. Terrestrial laser scanning (TLS) shown to be capable providing three-dimensional (3D) stem reconstructions required revealing differences between shapes sizes. In this study, we used 3D stems from TLS an unmanned aerial vehicle (UAV) investigate how...

Abstract Tree functional traits together with processes such as forest regeneration, growth, and mortality affect tree structure. Forest management inherently impacts these processes. Moreover, structure, biodiversity, resilience, carbon uptake can be sustained enhanced activities. To assess structural complexity of individual trees, comprehensive quantitative measures are needed, they often lacking for current practices. Here, we utilized 3D information from Scots pine ( Pinus sylvestris...

The great interest in continuous cover forestry (CCF) Finland has increased the need for tools to predict tree growth uneven-aged stands. Growth predictions are commonly obtained with stand simulators like MOTTI, which is primarily targeted at even-aged stands rotation (RF) Finland. aims of this study were: 1) test how existing individual models MOTTI worked Norway spruce trees growing Finland; 2) identify significant predictors if biases were detected; and 3) compile calibration diameter or...

In forest management there is a tendency towards measuring less and simulating more. this context the development of reliable, user friendly simulators has become economically relevant. The objective perspective paper to highlight recent trends in simulation identify remaining challenges make reliable tool for policy management. Experiences with various purposes different geographical contexts illustrate how important decision support can be addressed through flexible customization end-user...
