Stratified sampling was conducted across four elevation zones on the northern and southern slopes. Phytosociological parameters - including density, basal area, importance value index, and diversity indices - were assessed, and Pearson correlations were used to evaluate relationships with altitude and aspect. A total of 61 woody species from 43 genera and 26 families were recorded, highlighting the region's biodiversity. Tree and shrub density and basal area increased with elevation, particularly on northern slopes. Juniperus phoenicea L. emerged as the most dominant tree, while Phlomis floccosa D. Don and Pistacia lentiscus L. dominated the shrub layer. Diversity indices showed negative correlations with altitude, indicating declining species richness and evenness at higher elevations under cooler temperatures and greater environmental stress. Ten endemic woody species were documented, with endemic richness positively associated with altitude, reflecting the role of habitat isolation and environmental filtering. These findings provide essential insights for biodiversity conservation, climate adaptation, and ecosystem management in Al-Jabal Al-Akhdar and comparable mountainous ecosystems.

It had its maximum spread in the 16th century, when an estimated 36% of all forested land in Europe was managed for coppice. Coppice forests were the most important source of fuelwood until the mid-19th century, when firewood and charcoal were substituted by alternative fuels, and the demand for construction wood increased. Consequently, coppices (both low and coppice-with-standards) started to be converted to high forests, and the process was driven by national policies and/or subsidies, which is still the situation in some European countries. During the 20th century, coppicing was abandoned in many places across Europe due to the abandonment of the countryside and population migration into cities, as well as changes in socio-economic conditions, technical advances and political restrictions. However, coppicing is still important in many European countries as the main source of firewood for the rural population, who has limited access to other sources of energy. In this context, this paper presents the most important characteristics of this complex abandonment/management/conversion picture, emphasising the pros and cons for the future of coppices across Europe.

We focused on sessile oak [Quercus petraea agg. (Matt.) Liebl.] stands over 90 years old at two contrasting sites near Brno (South Moravian Region, Czech Republic): one actively managed and one left unmanaged for more than 40 years as a strict nature reserve. Tree heights were analysed using two-factor analysis of variance (ANOVA) with post hoc tests and multinomial logistic regression. A total of 1 239 trees were measured (584 stools and 655 standards). Standard trees were the tallest on average (21.8 m), significantly exceeding all the stool categories, whereas managed triple-stem stools were the shortest (15.97 m). Across all categories, unmanaged stands generally reached greater heights than managed stands did, except for standard trees. The forest type, exposure and slope had significant effects on height class probabilities, whereas elevation was important only for smaller trees. Overall, the results demonstrate that both the tree type and site conditions strongly influence height growth in Q. petraea coppice-with-standards stands, with management history leaving a clear biological legacy in the present-day stand structure.

At its western, oceanic range margin in the Swiss Prealps, the Swiss stone pine (Pinus cembra L.) occurs on large boulders embedded within subalpine forests dominated by Norway spruce [Picea abies (L.) H. Karst.]. We hypothesised that these landforms generate a continental-like microclimate enabling P. cembra persistence under otherwise sub-oceanic conditions, and we aimed to quantify this phenomenon. Using high-resolution data loggers, we measured air and soil temperature, thermal amplitudes, and soil moisture on the summits and at the bases of ten limestone boulders over a two-year period. Linear mixed-effects models revealed a pronounced microclimatic decoupling between positions. Boulder summits were consistently warmer and drier during the growing season. In contrast, during winter, summits were significantly colder, while boulder bases remained thermally stable due to persistent snow insulation. The strongest microclimatic divergence occurred in spring, when temperatures at the bases remained stable near 0 °C, whereas summit temperatures were markedly warmer and more variable. This continental-like microclimate likely promotes P. cembra persistence. Our results highlight the importance of topographic heterogeneity for maintaining marginal tree populations.
