Natural disturbances risks in European Boreal and Temperate forests and their links to climate change – A review of modelling approaches

Forest Ecology and Management, Journal Year: 2022, Volume and Issue: 509, P. 120071 - 120071

It is expected that European Boreal and Temperate forests will be greatly affected by climate change, causing natural disturbances to increase in frequency severity. To detangle how, through forest management, we can make less vulnerable the impact of disturbances, need include risks such our decision-making tools. The present review investigates: i) how most important forestry-related are linked ii) different modelling approaches assess their applicability for large-scale management planning. Global warming decrease frozen soil periods, which increases root rot, snow, ice wind damage, cascading into an increment bark beetle damage. Central Europe experience a precipitation temperature, lowers tree defenses against beetles rot infestations. Ice wet snow damages Northern forests, reduce Southern forests. However, lack cover may cases frost-damaged seedlings. increased temperatures drought together with fuel from other likely enhance wildfire risk, especially For approaches, thirty-nine disturbance models were assessed categorized according required input variables models' outputs. Probability usually common all model however, predict effects seem scarce.

Long‐term forest monitoring reveals constant mortality rise in European forests

Plant Biology, Journal Year: 2022, Volume and Issue: 24(7), P. 1108 - 1119

Published: Sept. 28, 2022

Abstract European forests are an important source for timber production, human welfare, income, protection and biodiversity. During the last two decades, Europe has experienced a number of droughts which have been exceptional within 500 years, both in terms duration intensity. These seem to leave remarkable imprints on mortality dynamics forests. However, systematic observations tree decline, with emphasis single species, scarce so far that our understanding drought occurrence is still limited at continental scale. Here, we make use ICP Forest crown defoliation dataset, permitting us retrospectively monitor all major conifers, broadleaves, as well pooled dataset minor species Europe. In total, analysed more than three million gathered during 25 years employed high‐resolution index can assess soil moisture anomaly based hydrological water‐balance runoff model. We found overall species‐specific increasing trends rates, accompanied by decreasing moisture. A generalized linear mixed model identified previous‐year most driver patterns but response was not uniform across numerous plots. conclude currently reaching concerning upward trend could be further accelerated global change‐type near future.

Evaluating Recent and Future Climatic Suitability for the Cultivation of Norway Spruce in the Czech Republic in Comparison with Observed Tree Cover Loss between 2001 and 2020

Forests, Journal Year: 2021, Volume and Issue: 12(12), P. 1687 - 1687

Published: Dec. 2, 2021

The high portion of secondary Norway spruce in Central European forests constitutes a major problem because significant part these is moving further away from their original bioclimatic envelope. precise evaluation and prediction climatic suitability are needed for the implementation forest adaptation strategies. We evaluated cultivation Czech Republic forests, making use Random Forest combined learning statistical method. presented was based on comparison with normal period 1961–1990; change analysis carried out 1991–2014 projected 2021–2040 2041–2060. found that suitable conditions will remain only 11.3% by area 2041–2060 vs. 46.0% 1961–1990. also compared tree cover loss data (using Global Watch) 2001 to 2020 statistics salvage logging. In period, affected 19.5% more than 30% spruce. relationships between relative percentage logging caused insects were conclusive statistically significant.

Assessing uncertainties in landslide susceptibility predictions in a changing environment (Styrian Basin, Austria)

Natural hazards and earth system sciences, Journal Year: 2023, Volume and Issue: 23(1), P. 205 - 229

Published: Jan. 18, 2023

Abstract. The assessment of uncertainties in landslide susceptibility modelling a changing environment is an important, yet often neglected, task. In Austrian case study, we investigated the uncertainty cascade storylines emerging from climate change and parametric model uncertainty. June 2009, extreme events heavy thunderstorms occurred Styrian Basin, triggering thousands landslides. Using storyline approach, discovered generally lower for pre-industrial climate, while future (2071–2100) potential increase 35 % highly susceptible areas (storyline much heavier rain) may be compensated by drier soils (−45 to landsliding). However, estimated predictions were high. While related within-event internal variability substantially than (ratio around 0.25), same order as scenario higher warming levels (+3 +4 K). We suggest that assessments, improved availability event-based inventories high-resolution soil precipitation data will help reduce models used assess impacts on hazard risk.

Question: We compared the soil organic carbon stock of forests an entire country. The objective our research was establishing differences between coniferous or deciduous with respect to stocks. question is relevant because are increasingly damaged by abiotic and biotic disturbances that related climate change. Deciduous considered be less vulnerable. Their soils expected more persistent reliable sinks for dioxide. Methods: Soil data available from Austrian Forest Survey. Soils have been sampled on sites Inventory. were stratified according geology (calcareous vs. silicatic bedrock), orientation slopes, forest type (coniferous mixed-deciduous forest). These used establish ground truth Further, we had simulation results a coupled growth/soil model. scenarios built Inventory 2007/09 reflect business-as-usual management climate-change adaptation scenario where managers replace if site conditions permit it. simulations performed growth simulator CÂLDIS model Yasso07. Results: Based Survey stocks consistently higher than in forests. This result applies both litter layer mineral depth 50 cm. gradients similar types. under strong warming showed increase when conifers replaced tree species. In 150-year majority will become suitable build-up large driven stronger harvesting pressure remaining lesser demand developed light intervention regime. However, toward end century, temperature level far above present levels, declined.
