In this paper, we simulated forest development over a 70-year planning horizon and evaluated the effect of different management strategies on spruce bark beetle susceptibility, timber production biodiversity indicators. We used national inventory plots located in Kronoberg county, Southern Sweden, from 2016 to 2020 perform analyses. A reference strategy mimicking current practices was compared with four other that can be an alternative decrease damage.

Abstract Climate change has increased the susceptibility of forest ecosystems, resulting in escalated decline globally. As one largest biomasses Northern Hemisphere, Eurasian boreal forests are subjected to frequent drought, windthrow, and high-temperature disturbances. Over last century, bark beetle outbreaks have emerged as a major biotic threat these forests, extensive tree mortality. Despite implementing various management strategies mitigate populations reduce mortality, none been effective. Moreover, altered disturbance regimes due changing climate facilitated success attacks with shorter multivoltine life cycles, consequently inciting more beetle-caused This review explores population dynamics context change, stand dynamics, strategies. Additionally, it examines recent advancements like remote sensing canine detection infested trees focuses on cutting-edge molecular approaches including RNAi-nanoparticle complexes, RNAi-symbiotic microbes, sterile insect technique, CRISPR/Cas9-based methods. These diverse novel potential effectively address challenges associated managing beetles improving health response climate.

Disturbances caused by the European spruce bark beetle (SBB; Ips typographus L.) on Norway (Picea abies (L.) H. Karst.), have increased immensely across Central and Northern Europe, are expected to increase further as a result of climate change. While this trend has been noted in Finland, so far limited research published. To support proper SBB risk management we compared stand properties between salvage loggings due damage during 2012–2020 (4691 cases) stands free damage. Also, explored role landscape attributes drivers We considered forest site fertility class, development soil type, mean diameter at breast height age. Considered were distance from SBB-damaged closest clear-cut, previous-year wind-damaged stand. used nationwide logging stock data, analysed using chi-squared Mann-Whitney U tests generalised linear mixed models. Based our findings, didn’t randomly, but prevailed mature (high age high height), herb-rich heath types semi-coarse or coarse soils. found correlation variables number loggings, with higher close clear-cuts.

Abstract Managing forest health is a critical challenge for managers and policymakers worldwide, especially in connected forests where ecological socio-economic linkages are tightly intertwined. Conservation sustainable management of ecosystems require the development implementation comprehensive strategies that address complex interactions between natural human-driven stressors affecting health. In this chapter, we review main drivers degradation provide an overview approaches tools can be used to monitor manage We highlight importance integrating practical knowledge with scientific information enhance resilience global environmental changes. Finally, discuss challenges opportunities associated managing landscapes, suggest possible improve management.

The European spruce bark beetle (SBB) is an important insect pest in many countries such as Sweden and has caused the loss of millions trees over past few decades. Forest management targeting key variables forest can be a potential tool to decrease SBB susceptibility. In this paper, we simulated development 70-year planning horizon evaluated effect different strategies on susceptibility, timber production biodiversity indicators. We used national inventory plots located Kronoberg county, Southern Sweden, from 2016 2020 perform analyses. A reference strategy mimicking current practices was compared with four other that alternative damage. were (1) mixed stands, (2) shorter rotations no thinnings, (3) prolonged (4) continuous cover forestry. differed how when regeneration, pre-commercial thinning, thinnings final fellings performed. optimization each aimed at reducing susceptibility while simultaneously investigating trade-offs range demands. addition, combined where any could chosen objective Also, respect indicators described Swedish environmental quality Living Forests. results show combination all most effective option manage achieve lowest average analysed area. Shorter rotation also resulted low leading large reductions abundance stem diameter Norway landscape lower values. Our suggest various strategies, alone or others, successfully employed However, achieving multiple objectives simultaneously, promotion biodiversity, may require additional constraints mathematical models addition settings describe strategies. Future work should explore incorporating these better optimize decisions.

In recent decades, increases in severe drought, heat extremes, and bark beetle outbreaks have increased global tree mortality. These risks are expected to be exacerbated under projected climate change. So far, observations of mortality mainly based on manual field surveys with limited spatial coverage. The lack accurate data over large areas has the development applications models. However, a combination high-resolution remote sensing data, such as aerial imagery automated analysis, may provide solution this problem. study, we analysed dynamics drivers forest canopy (standing dead trees) approximately 1200 km2 boreal Southeast Finland, between 2017-2023. For purpose, first developed convolutional neural network (CNN) U-Net architecture, automatically segment standing wood from 2017, 2020, 2023 resolution 0.5 m. Secondly, trained model using dataset consisting 32555 manually delineated segments various geographic regions Finland. showed high accuracy detecting trees (with an F1 score 0.86-0.93) when tested independent validation dataset.
