Woodlots are located on the border of the Highlands Region and the South Moravian Region in the heterogeneous wooded landscape. Birds were monitored in 11 woodlots using two approaches – line transect and camera traps. The line transects took place between 2020 and 2022 in the spring and autumn, and monitoring with camera traps took place from March 2022 to December 2023. In the woodlots, spatial and structural characteristics such as height, width, length, circumference, and area of the woodlot stand were measured. Processing of the data obtained was carried out in the GIS system and overall evaluation in the statistical program R and Canoco 5 using the GLMM and pCCA methods. We revealed that each bird monitoring method captured a different spectrum of bird species depending on the woodlot geometry. The bird species composition of long, narrow and bushy woodlots was better matched by species recorded by camera traps, and the species composition of wide woodlots with taller and older forest stands was better matched by species records from transect. Regarding the use of traditional ornithological methods and camera traps, for the best results, it is advisable to combine both methods.","PeriodicalId":515466,"journal":{"name":"Zprávy lesnického výzkumu","volume":"99 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141657246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, evaluating disturbances’ spatial and temporal extent and synchronicity is critical for understanding of forest dynamics. This study aimed to evaluate the long-term natural disturbance history of primary mixed-beech forests and investigate the species composition-temporal synchronisation relationship. We collected a unique dataset of > 6,000 tree cores across 14 forest stands on 174 study plots, and using dendroecological methods we reconstructed 200-year-long plot-level disturbance histories and evaluated synchronicity within the stands. Subsequently, we used GLMs to evaluate the tree species diversity-synchronicity relationship. The results showed substantial temporal variability of natural disturbances and a prevalence of low and moderate severity disturbances. Disturbance synchronisation was higher in the Western than in the Eastern Carpathian forests, which have a lower proportion of admixture tree species. Moreover, the GLMs showed a strong positive dependence of synchronicity on tree species richness. The results contradict the general assumption that mixed-species forests have higher resilience to disturbances than monospecific forests. The reason behind these findings can be attributed to the substantial admixture of Norway spruce, and its vulnerability to disturbances such as windthrow and bark beetle outbreaks.","PeriodicalId":515466,"journal":{"name":"Zprávy lesnického výzkumu","volume":"87 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141657670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its deciduous needles, it is relatively resistant to immission, and therefore it was used to establish substitute forest stands. Substitute forest stands were established in the 1970s and 1980s in heavily immissioned mountain and foothill areas with the intention of preserving the continuity of the forest environment and, in the case of larch, to partially replace the timber production of declining spruce stands. The aim of the study is to evaluate the effect of thinning on growth of a non-mixed larch stand in specific conditions of substitute forest stands at the age of 11–29 years. Thinning resulted in acceleration of the diameter growth of the released trees and improvement of their static stability in terms of reduction of the height-diameter ratio (HDR). The treatment where thinning at the age of 11 years was applied (treatment 3) showed a more favourable HDR of individual trees compared to the control, but the results were less satisfactory in terms of crown ratio (CR). The treatment with two thinning interventions at the age 11 and 20 years (treatment 2) produced satisfactory results both in terms of HDR and CR. However, the strong thinning at the age 20, when the stand was curtailed to only 320 trees per hectare, drastically reduced the basal area and is likely to result in a loss of production compared to the more moderate thinning options. However, in substitute forest stands, volume production is not the primary goal.","PeriodicalId":515466,"journal":{"name":"Zprávy lesnického výzkumu","volume":"18 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141658826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article provides a comprehensive review of current knowledge on the adaptation strategies of European beech in response to changing climatic conditions, highlighting its ecological demands, development of taxonomy, ecological and economic importance and exploring its resilience, growth characteristics, and challenges such as water regime, pests, diseases, and the impact of climate change. A key finding is that despite the various stressors affecting European beech, adaptive management and the use of mixed forest stands can significantly contribute to its conservation and sustainable use. The importance of integrating the genetic diversity and adaptive capacity of European beech into forestry practices is emphasised. The review of 203 studies highlights the need for further research focused on understanding the interactions between European beech and a changing climate in order to develop more effective strategies for its conservation and sustainable management in the future.","PeriodicalId":515466,"journal":{"name":"Zprávy lesnického výzkumu","volume":"29 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140743845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was established in a seventeen-year-old naturally regenerated stands using a block design with two replications. The silvicultural intervention (thinning) involved reducing the number of trees to 1,800 per hectare in the stand without pine representation and reducing it to approximately 4,000 trees in the less mature stand in the mixture with pine. The results of a thirteen-year time series since the implementation of the initial thinning are presented. The diameter growth of Douglas-fir on these sites is significantly lower compared to Scots pine. Without thinning, Douglas-fir is gradually being displaced by Scots pine in the stand, leading to a decrease in its representation and basal area. The silvicultural intervention have positively influenced diameter increment and improved the static properties of the trees, as expressed by their height-diameter ratio (HDR). In the thinned plot without pine occurrence, it was even possible to temporarily reduce the HDR values of target Douglas-fir trees. In the thinned plot with pine competition, the rate of HDR increase was only reduced compared to the control.","PeriodicalId":515466,"journal":{"name":"Zprávy lesnického výzkumu","volume":"50 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140742973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
