Summary: Climate change has increased the frequency and intensity of droughts and heat waves, impacting the growth and mortality risk of forests. The effects of thinning on species' responses to climate variation are highly variable, especially for broad-leaved species. This study assessed the effects of thinning on the growth sensitivity and response to extreme drought events of Eucalyptus grandis. The results showed that increasing thinning intensity improved the growth capacity and reduced the sensitivity to water balance, especially for two-stage thinning.

Summary: The study in Chilean Andes evaluated the growth patterns, climate response, and drought resilience of Nothofagus obliqua forests across different latitudinal gradients. Tree growth was found to be influenced by stand dynamics and related to precipitation, with a negative impact from maximum temperature. The two northern stands showed higher resilience to drought, while overall climate conditions did not solely define the tolerance of stands, as local environmental factors played a significant role.

Summary: Understanding the impact of management on post-drought tree growth recovery and drought legacy effects is crucial for the improvement of forest conservation strategies. This study analyzed tree-ring datasets from non-managed and managed Qinghai spruce forests in China, revealing that management practices can improve growth resilience to drought and mitigate drought legacy effects. However, the effectiveness of management is weaker during a prolonged drought. Therefore, tailored strategies and measures are needed for forest conservation in the face of exacerbated drought conditions.

Summary: This study analyzed the long-term response of European beech trees in Croatia to climate factors and found that precipitation played a significant role in radial increment and vitality, while temperature had a lesser impact. The study also revealed differences in the response of beech trees between the alpine and continental biogeographical regions.

Summary: Eucalyptus grandis trees showed significant growth reduction under a 3-year period of extreme water deficit, but exhibited great recovery ability in terms of basal area growth. During the recovery period, trees were able to recover 51% of their basal area, despite only 5% recovery in total height. Rapid responses to rainfall variation were observed during the water deficit period, indicating high resilience and conservation of the xylem vascular system in the trees.

Summary: Climate change-triggered forest die-off is a growing threat to global forests, but predicting it remains challenging. This study examines the relationship between tree growth resilience to drought and stand-level mortality using a large tree-ring dataset from the US Mountain West. The results show that declining resilience and low tree growth are strongly associated with mortality patterns. However, the potential for tree growth resilience to improve large-scale predictions of forest die-off under climate change is only moderate.

Summary: Transformational change is needed to protect the world's natural resources. Ambitious forest restoration efforts are crucial in achieving this change, with the success of restoration depending on trees' ability to withstand various stressors, especially drought. Research often overlooks the significance of the former land use in determining the predisposition of trees to resist drought, potentially leading to wasted restoration efforts.

Summary: Tropical reforestation is a powerful tool for carbon sequestration, but climate change impacts on productivity are often overlooked. Using a forest growth model, the study analyzed future productivity and found that temperature increase can lead to significant declines in productivity across tropical lowland climate zones. High-emission scenarios could reduce reforestation effectiveness as a climate action tool.

Summary: Climate change is impacting tree growth and vitality, with urban trees in Canberra showing different responses based on heat tolerance, drought tolerance, leaf phenology, and age. Water deficit poses a significant threat to tree health in the city, with trees exhibiting symptoms such as dead branches and crown dieback. Management strategies need to be adapted to address these changes, including updating growth models to improve predictions.

Summary: Global climate change and increased drought frequency and intensity have resulted in forest decline and tree mortality. By studying the resilience components of tree growth to drought, including resistance, recovery, and resilience, as well as the influencing factors, this study helps assess the production and ecological stability of forests under a changing climate. The findings highlight the importance of drought severity and individual-tree characteristics in influencing drought resilience components, which can inform future adaptive management of natural Mongolian pine forests.

Summary: Climate warming has increased the frequency and severity of drought events, negatively affecting tree radial growth in drought-prone regions like the Mediterranean. The growth responses of tree populations to climate change are influenced by tree age and local environment, leading to geographical patterns in tree growth and forest productivity. Intraspecific variability in sensitivity to drought events should be considered in predicting forest productivity responses to climate change.

Summary: The Trajetorias dataset is a comprehensive set of environmental, epidemiological, and poverty indicators for all municipalities in the Brazilian Legal Amazon. It consolidates multidisciplinary indicators into a coherent dataset for integrated and interdisciplinary studies of the region. This dataset enables the investigation of the relationship between agrarian systems and their impact on environmental and epidemiological changes in the Amazon forest.

Summary: As climate change leads to increased drought, understanding the response of forests and the impact of forest management becomes crucial. This study found that restoration treatments, such as reducing stand density through fire or mechanical thinning, can mitigate mortality during drought. However, the effects on tree growth during drought vary depending on climate and tree size. The results suggest that density reduction treatments can improve tree resistance to water stress and have implications for carbon sequestration and ecosystem services.

Summary: Warming temperatures and droughts are causing widespread forest dieback and growth decline. Different tree species respond differently to precipitation and temperature, with declining trees exhibiting altered climate memory of growth. The sensitivity and memory of climate conditions vary between declining and non-declining trees.

Summary: Climate change is causing more severe and frequent droughts, leading to tree mortality and reduction in ecosystem services. Mixed stands are more resilient to drought compared to pure stands, and there is limited knowledge on the drought susceptibility of Norway spruce and Scots pine when coexisting. Norway spruce is more vulnerable to summer drought with lower resistance and longer recovery time than Scots pine. Mixed stands provide higher drought resistance for both species, but the advantage decreases with longer drought duration. Climate-sensitive and old trees in marginal sites are more affected by drought stress. Promoting Scots pine and mixed forests is a promising strategy for adapting to climate change.
