“…Trying to compare the obtained values with results obtained by other researchers, no data were found in reference literature for the drying rate of Turkey oak. For 50mm thick European oak, Sergovski (1968) indicates an average drying rate of 0.1%/h, meaning 2.4%/day from 60% to 12% moisture content, and Unsal (2002) indicates an average drying rate of 0.04%/h, meaning 0.96%/day from 60% to 9.7% moisture content. The higher drying temperatures used in the the two cited references, and the fact that no differentiation between the free water and bound water removal was made, may explain why their reported values were higher.…”

Black locust (Robinia pseudoacacia L.) is the most widespread non-native tree species in Europe and has had a significant impact on the Central European landscape and forestry. The black locust has many exceptional characteristics that represent considerable potential for use by man. The climate shift in recent decades in Central Europe could further strengthen the importance of this tree species. However, there are also risks arising from the invasiveness of the black locust. Like Hungary, Czechia has had many years of experience with this tree species. Still, the current approach between these two countries, particularly in conventional forestry, differs. This paper attempts to summarise how the management of Robinia and its stands is viewed in Czechia, where the common forestry utilization of black locust is currently not considered due to its invasiveness. The reason for a more reserved forestry attitude in Czechia can be associated with the relatively frequent stem deformities of Robinia stands, which are often attributed to frost. However, the frost deformities and low stem-form quality of some Robinia stands do not affect their vigour and potential to invade adjacent habitats. It often takes considerable effort to remove black locust, especially where the spreading of Robinia threatens valuable adjacent ecosystems. On the other hand, there is great potential for the use of Robinia in Czechia. It can be found in controlled energy crops, fast-growing plantations (lignicultures), some land reclamation projects or urban greenery. Robinia can also be grown in small stands or in groups of trees surrounded by arable land that does not allow the tree to spontaneously spread. Regarding the production plantations of Robinia, the Hungarian experience and breeding program can be very inspiring for Czechia. Generally, there is a move towards 'site-specific management', but with a strong emphasis on the precautionary principle. Finding and then consistently applying a balanced approach to black locust management that not only allows for the potential but also respects the risks of Robiniait is currently a key challenge for Czech forestry, landscape and nature conservation.

“…Generally, high temperatures in the growing season can induce increased water stress and a subsequent reduction in radial growth due to increased water loss through evapotranspiration and soil moisture evaporation. Stafasani & Toromani [126] reported that most of the coppice Turkey oak mixture stands in Albania showed extreme drought in June of the current year as a limiting factor for growth. The negative effect of June and July temperatures on the growth of young oaks has previously been observed at several sites in continental Europe [127,128] in northern Spain [129] and also in the Mediterranean [130,131].…”

Turkey oak (Quercus cerris L.) is a thermophilic oak species that is gaining importance in the context of ongoing climate change because of its better resistance to climatic extremes and drier conditions. Therefore, this article focuses on Turkey oak’s role and growth properties in the coppice forests of Southern Europe (Italy, Bulgaria) compared to similar site conditions in Central Europe (Slovakia, Czechia). The aims are to evaluate the basic dendrometry indicators, stand biodiversity, growth dynamics, and the effect of climatic factors on tree-ring increment on specific site chronologies. We found that the tree density in coppices of 50–60 years varied between 475 and 775 trees ha−1, and the stand volume ranged from 141 to 407 m3 ha−1. The complex stand diversity of all plots ranged from a monotonous to uniform structure. The size of tree-ring growth was closely related to indicators of stand density. The lowest influence of climatic factors on tree-ring growth was found in sites in Italy and the highest in Slovakia. The primary limiting factor for growth was the lack of precipitation during the growing season, especially in June and July. In contrast, temperature had a marginal effect on radial growth compared to precipitation. The radial growth in research plots in Southern Europe goes through longer 6 to 8-year growth cycles, and in Central European sites, it goes through shorter cycles of 2.4 to 4.8 years, which confirms better growth conditions in this region. The studied coppice stands exhibit a stable reaction to climate change. Yet, regarding cyclical growth, the Central European stands benefit from an advantageous climate and grow better than in Southern Europe. As part of the changing environmental conditions, Turkey oak is becoming an important tree species that can achieve high production potential even in drier habitats due to its regeneration characteristic as coppice and may play a critical role in its northerly introduction in Europe.

“…Furthermore, extra sugar is stored in winter tree, which will be available for tree growth till next summer (LaMarche 1974). The dendroclimatological analyses showed that the positive moisture balance in current April and previous September was the dominant climatic factor favoring the radial growth of Quercus cerris in Albania (Stafasani, and Toromani, 2015). Some discrepancies in the regional responses of the studied species mean that regional patterns of stand productivity may be not necessarily extrapolated to the transcontinental level (Huang et al 2010).…”

Background The main pool of publications on this topic is related to the assessment of possible changes in vegetation growth under the influence of climate, but few of them actually took account the impacts of global change on species composition and morphological (taxational) structure, so led to an unanswered question, how the biological productivity of the forests will change if air temperature and/or precipitation change up to a certain extent. This is a subject of the study. Methods In this study, our database is used in a number of 2,110 sample plots for pine and 510 for birch. In each sample plot, the biomass of the forest stands was positioned in maps of January mean temperature isolines and to mean annual precipitation ones, and the input data matrix was compiled in which the values of biomass components and of stand taxation characteristics are mated with corresponding values of climate indices. The matrix was then subjected to regression analysis. Results It is stated, in cold and insufficiently moisture–rich climate zones, temperature increase causes a decrease in biomass of Pinus foliage, and in other regions its increase, but the Betula pattern is the opposite. With an increase in precipitation, the Pinus foliage biomass in warm zones increase, and in cold ones it decreases, but the Betula pattern is the opposite. Conclusion The biomass of pine and birch stands change in gradients of winter temperature and precipitation as propeller-formed but opposite patterns, which can be explained by the different winter physiology of evergreen and deciduous species.
