In recent years, climate change has led to drought and severe bark beetle infestations, affecting Norway spruce (<em>Picea abies</em>) across Europe, with detrimental consequences for forest owners, the forestry sector and associated industries. As a result, silviculture now faces the challenge of identifying tree species more resilient to these stressors to mitigate the impacts on forest management, forest-dependent economies and rural livelihoods. The North American Douglas-fir (<em>Pseudotsuga menziesii</em>) has emerged as a promising conifer species, better suited to future climate conditions and capable of producing high timber yields.</div><div>2.

In this study, we examined how incorporating neighborhood competition improves biomass prediction accuracy and how the influence of neighborhood competition differs between Scots pine (<em>Pinus sylvestris</em> L.) and Pyrenean oak (<em>Quercus pyrenaica</em> Willd.), as well as the relative contributions of intra- and interspecific competition to AGB.

This addition reduced the root mean square error (RMSE) by 14% and improved the model efficiency factor (MEF) by 15%. Furthermore, intraspecific competition in Scots pine slightly reduced AGB, whereas interspecific competition had a significant negative effect on AGB. In contrast, DBH alone was the best predictor of AGB for Pyrenean oak, as neighborhood competition did not improve model performance. Also, intra- and interspecific competition in Pyrenean oak had positive but nonsignificant effects on AGB.

However, data describing the long-term response of temperate rainforests to disturbance is rare. In the cool temperate rainforests of northern New South Wales, Australia, <em>Nothofagus moorei</em> is considered especially vulnerable to climate change due to a decreasing number of mature individuals, limited remaining suitable habitat, and low rates of sexual regeneration. In this study, we used over 50 years of empirical data from silvicultural experiments with multiple thinning intensities to characterise the demographic responses (i.e., growth, mortality, and recruitment) of cool temperate rainforest species, including <em>N. moorei</em>, to disturbance over time. Cool temperate rainforest species showed resilience to disturbance, predominantly through their widespread ability to basally coppice. <em>Nothofagus moorei</em>, in particular, demonstrated higher rates of successful sexual and vegetative recruitment and grew faster in response to higher intensities of disturbance, in comparison to very low rates of recruitment pre-disturbance. These results challenge successional models that position rainforests as disturbance-sensitive ecosystems and identify <em>N. moorei</em> as a species that requires large-scale disturbance to successfully regenerate.

For shade-intolerant pines of the southern United States, however, few studies have examined residual tree growth following silvicultural treatments that convert even-aged stands to multi-aged stands. Understanding the growth response of residual trees to different kinds of stand conversion treatments is critical to stand development and sustainability, as trees must be recruited into larger size classes during the conversion process to develop the desired stand structure and maintain productivity. In this study, we utilized a replicated, long-term silvicultural experimental trial in the southeastern United States to assess the effects of two cutting treatments (dispersed “single tree cutting” that created small canopy gaps and the “patch cutting” that created 0.1–0.8 ​ha patch openings) and an uncut control on the 14-year growth (∼cutting cycle length) of residual longleaf pine (<em>Pinus palustris</em> Mill.) trees. We found that tree growth, measured as mean basal area increment (BAI), was significantly higher following patch cutting (mean BAI of 16.97 ​cm²) compared to both the single tree cutting (13.33 ​cm²) and the uncut control (12.68 ​cm²) (<em>p</em> ​&lt; ​0.001). In patch cutting, the size of the patch opening, the location of trees surrounding the patch opening, and the position of the tree canopy all had a significant effect on BAI. Trees surrounding patch openings of 0.4 ​ha exhibited greater growth, with a mean BAI of 19.24 ​cm², compared to those surrounding 0.1 and 0.8 ​ha patch openings, which had mean BAI values of 15.89 and 15.71 ​cm², respectively (<em>p</em> ​&lt; ​0.001). The position of a tree around the patch opening also influenced tree growth, as residual trees more to the North, South, and East sides exhibited significantly higher mean BAI than trees on the West side of the patch openings (<em>p</em> ​&lt; ​0.001). However, distance from the patch opening border did not significantly affect the mean BAI (<em>p</em> ​= ​0.522). In all treatments, dominant and co-dominant trees exhibited higher BAI than intermediate and overtopped trees, indicating that tree canopy position significantly influenced tree growth (<em>p</em> ​&lt; ​0.001).

This study is the first to focus on Băneasa Forest, the only urban forest in Bucharest, which serves as a vital recreational area for thousands of residents and visitors. For the first time in Romania, this research uses a web-based Participatory GIS survey to collect spatially referenced data. The survey, which combines questionnaires and mapping exercises, allows us to produce high-resolution CES maps based on 816 responses. The results reveal that the forest's natural characteristics are perceived as the primary contributors to CES. These findings are valuable for urban planners, as they highlight the needs and expectations of forest visitors, promote conservation efforts, and foster collaboration to prevent conflicts. Alongside factors frequently discussed in the literature, such as age and accessibility, the percentage of green space in residents' neighborhoods emerges as a significant factor influencing CES preferences. This insight presents a novel contribution to the literature, being of particular importance for urban planners and policymakers, as it underscores the need to consider not just the green space within parks and forests, but also the broader context of surrounding neighborhoods when planning for CES. Understanding that the availability of nearby green space influences residents' CES preferences can guide more effective strategies to enhance access to CES in urban areas, both in Bucharest and elsewhere.

One proposed strategy is competition reduction to increase water availability and, as a result, alleviate drought stress. This study investigates the effect of competition intensity on drought stress and tree growth in European beech (<em>Fagus sylvatica</em>) and pedunculate oak (<em>Quercus robur</em>). We deployed 72 point dendrometers, placed along a competition intensity gradient, in National Park Brabantse Wouden (Belgium), to measure daily minimum tree water deficit (TWD_min) as a drought stress proxy and daily radial growth at tree level. Our results revealed species-dependent effects of competition intensity (CI). For European beech, competition reductions positively influenced growth and alleviated (1 ​&lt; ​CI ​&lt; ​2) or aggravated (CI ​&lt; ​0.5) drought stress. For pedunculate oak, competition intensity did not affect drought stress or growth along the investigated gradient. Environmental variables consistently affected TWD_min and growth of both species. Precipitation reduced TWD_min and increased growth, while vapor pressure deficit led to opposite trends. Thus, environmental conditions and competition can play a critical role in forest dynamics, especially in light of climate change. However, reducing competition through increased management efforts does not seem to be a one-size-fits-all solution to alleviating drought stress. Additionally, there seems to be a trade-off between reducing drought stress and improving tree growth in European beech: tree growth continuously benefited from competition reductions, while under low competition (CI ​&lt; ​0.5) drought stress increased.
