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...
Mast seeding, the synchronised occurrence of large amounts fruits and seeds at irregular intervals, is a reproductive strategy in many wind-pollinated species. Although series studies have investigated mast year (MY) patterns European forest tree species regional scale, there are few recent evaluations scale on impact weather variables (weather cues) resource dynamics behaviour. Thus main objective this study to investigate specific conditions, as environmental drivers for MYs, resources...
Abstract Key message Exceedance of critical limits in soil solution samples was more frequent intensively monitored forest plots across Europe with loads for acidity and eutrophication exceeded compared to other from the same network. Elevated inorganic nitrogen concentrations tended be related less favourable nutritional status . Context Forests have been exposed elevated atmospheric deposition acidifying eutrophying sulphur compounds decades. Critical identified, below which damage due...

Damage risks in two forest management regimes were estimated by means of a literature review and questionnaire to Finnish forestry experts.• usually be higher even-aged than uneven-aged regimes.• In some cases, however, damage may stands (root-rot infected Norway spruce mechanical due repeated thinnings).
<ja:p>The occurrence of moose damage was studied using data from three National Forest Inventories (NFIs) accomplished between 1986 and 2008 in Finland. The combined included a total 97â390 young stands. proportion increased 3.6% to 8.6% the 8th NFI (1986â1994) 10th (2004â2008). majority (75%) occurred Scots pine-dominated higher aspen-dominated stands than dominated by any other tree species. species mixture also had clear effect on damage. Pure pine less mixed stands, decreased...
Empirical evaluation of visualizations has so far been typically carried out by measuring the performance participants that have shown visualization in relation to control group grading programming tasks. Such studies tell little about what effects take place during and how these build up into learning effects. To address issues, we are carrying a series experiments using tools whose long-term known.This paper presents model cognitive phenomena viewing sessions describes an experiment where...
The changing forest disturbance regimes emphasize the need for improved damage risk information. Here, our aim was to (1) improve current understanding of snow risks by assessing importance abiotic factors, particularly modelled load on trees, versus properties in predicting probability damage, (2) produce a map Finland. We also compared results winters with typical conditions and winter exceptionally heavy loads. To do this, we used observations from Finnish national inventory (NFI) create...
Data from 24544 pine-dominated plots of the Eighth National Forest Inventory (NFI) in southern Finland were used this study. The most commonly identified cause damage was Gremmeniella abietina (10.6% stands). Disease assessments by NFI groups reliable at stand level. disease spatially clustered, being almost twice as common on peatland mineral soil plots. However, there no difference between undrained peatlands and soils. more original site type had changed after drainage, disease. On soil,...
<ja:p>Field data of the 8th National Forest Inventory (NFI) from southern Finland and digital elevation models (DEMs) were used in this study. Damage due to Gremmeniella abietina increased slightly with an increase absolute mineral soils. Severe damage almost linearly soil plots. The mean tract area (the 7 km x 8 surrounding plot) was more strongly correlated disease than individual relative altitude plot important: most severe plots situated lower area, especially peatland In group,...
Abstract In 2006, the distribution and frequency of pine stem rust Cronartium flaccidum was studied on Melampyrum spp. in permanent sample plots an EU forest health monitoring program a BioSoil Finland. The infected with C. low, but recorded new locations eastern No uredinia were observed samples collected from over 700 plots. Telia common sylvaticum occasionally also found pratense nemorosum. most species growing mainly dry sites. seldom detected, suggesting that alternate hosts are absent...
