Forest value chain resilience from a local perspective in five European countries: analysis of predictors and co-drivers

Frontiers in Forests and Global Change, Journal Year: 2025, Volume and Issue: 7

Published: Jan. 7, 2025

Climate change-associated disturbances such as storms, wildfires, and pest outbreaks increasingly destabilize forest systems, threatening their ecological, economic, social functions. These disruptions impact the value chain (FVC) by causing fluctuations in timber supply, from a quantity quality perspective. This study employed operational resilience framework (ORF) to assess FVC five European case studies (CZ, HR, DE, FIN, ESP), focusing on supply key system variable. A assessment was conducted using thresholds, considering sustainability both ecological economic perspectives. Principal component analysis (PCA) identified three predictor groups that influenced resilience: wood production (WP), harvesting systems (HS), management silviculture (MS). Findings revealed regions with proactive sufficient processing capacities ESP) maintained relative stability despite natural disturbances, while others (DE FIN) experienced prolonged instability due market-driven logging practices limited adaptive measures. The highlighted frequent breaching of particularly during high-volume salvage following bark beetle outbreaks, windstorms, wildfires. results emphasized importance integrating strategies mitigate these impacts. ORF demonstrated potential for operationalizing provided guidance improving preparedness against future disturbances.

Biodiversity and Management as Central Players in the Network of Relationships Underlying Forest Resilience

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(5)

Published: May 1, 2025

ABSTRACT Global change is threatening the integrity of forest ecosystems worldwide, amplifying need for resilience‐based management to ensure their conservation and sustain services they provide. Yet, current efforts are still limited by lack implementation clear frameworks operationalizing resilience in decision‐making processes. To overcome this limitation, we aim identify reliable effective drivers resilience, considering synergies trade‐offs. From a comprehensive review 342 scientific articles addressing forests globally, identified factors shaping resilience. We recognized them into two categories that influence responses disturbances: predictors, which can be modified through management, codrivers, measurable but largely unmanageable (e.g., climate). then performed network analyses based on predictors codrivers underlying In total, 5332 such relationships linking or with attributes Our findings support central role biodiversity, mixed, non‐planted, functionally diverse promoting across all contexts biomes. While also enhanced success specific interventions was highly context‐dependent, suggesting its application requires careful analysis Specifically, practices like cutting prescribed burning generally terms tree growth, plant diversity, landscape vegetation cover, stand structure. contrast, pest herbivore control reduced taxonomic diversity while offering only minimal gains other variables.

Leafing Out: Leaf Area Index as an Indicator for Mountain Forest Recovery Following Mixed-Severity Wildfire in Southwest Colorado

Forests, Journal Year: 2025, Volume and Issue: 16(6), P. 872 - 872

Published: May 22, 2025

Wildfire is a critical driver of ecological processes in western U.S. forests, but recent shifts climate, land use, and fire suppression have altered forest structure disturbance regimes. Understanding post-fire recovery essential for management, particularly across complex montane landscapes like the southern Rocky Mountains. We assessed conifer ranging from ponderosa pine to spruce-fir, following large mixed-severity using field-based stand data remotely sensed Leaf Area Index (LAI) measurements. Our objectives were determine whether LAI meaningful proxy vegetative how patterns vary by type, burn severity, abiotic factors. Stand characteristics predicted crown severity inconsistently did not predict soil severity. correlated strongly with live overstory tree density shrub cover (R2 = 0.70). Recovery trajectories varied lower-severity burns generally recovering four years post-fire, while high-severity showed delayed recovery. Regeneration influenced higher seedling densities occurring at wetter sites. findings highlight utility as underscore importance climatic factors when assessing resilience.

Exploring spatial and temporal resilience in socio‐ecological systems: Evidence from sacred forests in Epirus, Greece

People and Nature, Journal Year: 2024, Volume and Issue: 6(3), P. 1206 - 1219

Published: April 1, 2024

Abstract Socio‐ecological resilience is the capacity of a system to adapt changing ecological and social disturbances. Its assessment extremely important integrate long‐term management features natural ecosystems. This especially true for Sacred Natural Sites, such as sacred forests groves, where it can reveal influence processes in ecosystem recovery or degradation. Using tree ages determined through dendrochronology population size‐class distributions collected five Epirus (NW Greece), we explore spatial temporal dynamics socio‐ecological system, identifying which cultural elements characterize space time. Our main results show that over past centuries underwent periods varying establishment rate, depending on intensity human activities historical disturbance events. We also identified strong evidence role component (i.e. church associated praxis) determining extent forests' current phase, thus overall system. Policy implications .

Patterns of early post-disturbance reorganization in Central European forests

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2031)

Published: Sept. 1, 2024

Disturbances catalyse change in forest ecosystems, and a climate-driven increase disturbance activity could accelerate reorganization. Here, we studied post-disturbance forests after the biggest pulse of tree mortality Central Europe at least 170 years, caused by drought bark beetle (Scolytinae) outbreaks 2018–2020. Our objectives were to characterize early state regeneration mortality, quantify patterns reorganization relative undisturbed reference conditions assess how management patch size affect disturbance. We surveyed 1244 plots 120 patches under managed (salvage-logged, often planted) unmanaged (deadwood remaining on site, no planting) Germany. found that density disturbed sites was high (median 11 897 stems ha −1 ), resulting from cohort advance regeneration. strong drivers change, with indications for resilience only 36.3% patches. Reassembly (i.e. species composition) dominant pattern (61.5%), Picea abies changed most strongly. Post-disturbance facilitated particularly promoting composition. The strength increased size. conclude recent wave will likely Europe.

Abstract Key message The UNFCCC COP 27 in Sharm El-Sheikh confirmed that climate policies too heavily rely on mitigation by forests rather than de-fossilizing the energy system, to keep global warming within safe 1.5 °C. Reliable would imply healthy productive well adapted change, and this is no longer case. current trend loss of forest vitality shows adaptation urgently needed, but measures are being insufficiently adopted foresters ground. In letter, we wonder about reasons for inaction paralyzing climate-smart forestry propose a way forward using diversity-based no-regret approach line with available knowledge.
