1. Balancing wood production and biodiversity in intensively managed boreal forest

Author:
Jeannette Eggers; Johanna Lundström; Tord Snäll; Karin Öhman
Source:
Scandinavian journal of forest research 2022 v.37 no.3 pp. 213-225
ISSN:
1651-1891
Subject:
biodiversity; boreal forests; forest management; landscapes; research; wood; Sweden
Abstract:
... Fennoscandian boreal forests are managed intensively for wood production, which has had a negative impact on biodiversity. The harvesting pressure on the forests is likely to increase in the future because wood is seen as an important resource in a bio-based economy. Thus, there is an urgent need to better describe the trade-offs between wood production and biodiversity, and to understand how thes ...

Abstract:
... The four-parameter Johnson's SB (JSB) and three-parameter Weibull distributions have received significant attention in the field of forestry for characterising diameters at breast height (DBH). This study suggests the Bayesian method for estimating parameters of the JSB distribution. The maximum likelihood approach uses iterative methods such as a Newton–Raphson (NR) algorithm for maximising the l ...

boreal forests; case studies; computer software; data collection; forest management; remote sensing; research; trees
Abstract:
... Monitoring the regeneration process of a forest is an important part of forestry management. Compared to traditional methods of counting tree species, UAVs have been a revolutionary means of saving time and costs due to the temporal and spatial flexibility of data collection. In turn, the integration of multispectral cameras allows the traditional vegetation indices that have been used with satell ...

Abstract:
... The new round of the Grain for Green Project (GGP) has unified the subsidy standards for economic and ecological forests. However, due to the difference between the afforestation density effect and management effect, the project’s ecological effect is different. Uniform payment standards may decouple afforestation investment from its ecological benefits, consequently affecting the cost-effectivene ...

Abstract:
... The heartwood of Dalbergia odorifera T. Chen (D. odorifera) is highly valuable. It was speculated that drought could promote heartwood formation in D. odorifera. To test this hypothesis, we artificially simulated conditions of low and high soil moisture content and investigated whether D. odorifera trees living in habitats with contrasting soil water conditions display distinct heartwood formation ...

Abstract:
... To develop recommendations for tree selection in Continuous Cover Forestry (CCF), access to valid tools for simulating growth at individual tree-level is necessary. To assist efforts to develop such tools, in this study, long-term observation data from two uneven-sized Norway spruce plots in southern Sweden are used to evaluate old and new individual-tree growth models (two established Swedish mod ...

Abstract:
... Forest protection in nature reserves in Norway relies on the voluntary participation of forest owners. While the national forest protection program has been a success since its start in early 1990s, by 2020 the national forest protection authorities were only halfway to reaching their goal of protecting 10% all forest area. We examined attitudes towards forest protection in general and towards dif ...

Stag beetle (Coleoptera: Lucanidae) larvae are saproxylic organisms specialized in living in deadwood colonized by microorganisms; these beetles are bioindicators of forest integrity and are currently under threat by habitat loss, climate change and intensive forest management. A multi-year collection of data on the habitat and microha ...

Abstract:
... Thinning experiments were primarily established for analysing how treatment variants determine the amount and quality of wood production. Given climate change, they may also explain how silvicultural treatment determined drought resistance. Especially for tree species cultivated in regions beyond their natural range, silvicultural treatment may help mitigate drought stress. Here, we used the 47-ye ...

Abstract:
... Transition towards a bio-based society requires large amounts of woody biomass to be converted into biofuels and biomaterials. Populus species are good candidates for growth in short rotations, but there is a lack of climate-adapted plant material suitable for growth at the high latitudes of the Nordic–Baltic region. Here we studied the growth and phenology traits in 63 Populus trichocarpa clones ...

Abstract:
... Precision forestry allows decision-making on tree level or pixel level, as compared to stand-level data. However, little is known about the importance of precision in thinning decisions and its long-term effects on within-stand variation, stand economy and growth. In this study, silviculture was optimized for Net Present Value (NPV) in 20 conifer-dominated forest stands in hemi-boreal southern Swe ...

Abstract:
... How seedling mortality and browsing affects species composition of regenerating forests has been mostly studied on a small scale. Yet, large-scale analyses based on extensive data are essential for robust prediction of species composition in young forests. In this study, we used a dataset from a national inventory of young forests (1–4 metres in height) to investigate the species composition of yo ...

Abstract:
... Even-aged management (rotation forestry, RF) involves ditch network maintenance (DNM) operations in peatlands. Although the DNM operations contribute tree growth, they have negative environmental effects on watercources. To avoid DNM, a strip cutting (SC) management has been proposed. SC management in peatlands relies on natural regeneration by trees growing on the edge stand next to a clear-cut s ...
