“…Eleven articles are devoted to the study of forest ecosystems (Table 2). Research was conducted on old-growth mesic broad-leaved forest [63][64][65], beech forests [66], Pinus nigra plantations [67], mixed mountain forests composed of Picea abies, Abies alba and Fagus sylvatica [68], old-growth spruce-fir forests [69] and others.…”

“…The studies of climatedriven dynamics for various types of vegetation deserve special attention [66,76,83,84]. Scientists considered the recovery dynamics for the alpine mountain bog [73], bare slopes [79], forests [64,67,68,85] and grasslands [86]. Climatic, soil, plant and anthropogenic factors were assessed for grasslands [53,60,61].…”

The conservation of biodiversity and ecosystem sustainability is essential for human well-being. An important tool for addressing this issue is ecological indicators. This overview document examines recent studies covering the period 2018–2022 that use the values of the Landolt indicator as one of the analysis methods. The total number of records examined was 8910. After excluding irrelevant, inconsistent and duplicate records, 91 records were selected. The selection criteria were the presence of the English abstract and a digital object identifier (DOI). We chose the VOSviewer software for data analysis and visualization. The analysis of research geography, types of plant communities under research, research topics, the network of co-authorship and relationship papers, as well as the publication activity and citation rate of the authors, is carried out. The results revealed that the geography of using Landolt indicator values is quite wide, while they are more often used in Switzerland, Italy and Russia. The most important and frequently cited studies were carried out in the context of large international projects, confirming the importance of scientific cooperation in the development of environmental indicators. The Landolt indicator values showed effectiveness in the study of forests, bogs, riparian vegetation, a coarse quarry waste dump, and in assessing the urban environment. At the same time, the vegetation dynamics and influence of various factors on plants were studied most often. It was revealed that Landolt indicator values can serve as an effective universal method that integrates many aspects of the environment and allows for a comprehensive multicriteria analysis of environmental factors, habitat stability, vegetation diversity and dynamics for different plant communities at different spatial scales over a wide geographical area. This is confirmed by the high citation rate of the papers. We recommend the Landolt indicator values for a wider use, including in the monitoring of ecosystems and individual species for their conservation and sustainable management. In order to achieve this goal, it is necessary to extend the network of relationships between the authors, which is not very well developed at the moment. The research results obtained are useful for the further successful development not only of the Landolt indicator values but also of environmental indicators in general.

“…Throughout the Mediterranean region, overexploitation and depletion of forest resources have had a profound impact on the ecosystems (Vogiatzakis et al 2006). The basic principles of NBFM are also appropriate for Mediterranean forests and there are many examples of uneven-aged management (Grassi et al 2003;Trasobares and Pukkala 2004;Diaci et al 2019), although processes such as deforestation, overgrazing and soil degradation with desertification, replacement by shrubs and fire-prone secondary conifer plantations must be considered. More than 95% of fires are caused by human activities, making societal measures essential (e.g.…”

The report benefited from the helpful comments from three external reviewers, Fernando Valladares from the Spanish Council for Scientific Research (CSIC), Janez Potočnik, ThinkForest President and co-chair of the International Resource Panel, and an anonymous reviewer. We wish to express our thanks for their insights and comments that helped to improve the report, and acknowledge that they are in no way responsible for any remaining errors.Closer-to-Nature Forest Management 3. Use adaptive management as a way to tackle uncertainties: We need to regularly monitor forest responses to management interventions, evaluate these responses and adjust management strategies accordingly.A similar adaptive approach is urgently required to evaluate the impact of policy measures and support mechanisms proposed to encourage adoption of Closer-to-Nature Forest Management. Not a quick-fix, long-term measures are needed:The introduction of Closer-to-Nature Forest Management is not a 'quick-fix' and policy makers must provide long-term and consistent support measures to encourage forest managers and other stakeholders to adopt this strategy. Support for forest owners for training and application of the strategy is key. Review existing subsidy and taxation regimes for private owners:Convincing private owners to follow this approach will require the creation of schemes that reward them for providing ecosystem services. Closer-to-Nature Forest Management has the potential to support biodiversity, adapt forests to climate change and provide ecosystem services to a higher level than conventional forest management. There is an urgent need to review existing subsidy and taxation regimes affecting private forestry, and to consider how these might be changed to further the uptake of Closer-to-Nature Forest Management. Develop and use new technologies and tools:There is a need to harmonize monitoring systems and to develop and use new technologies and tools (GIS, GPS and remote sensing) to ease management of these more diverse and structure-rich forests.Finally, there are still some uncertainties about the effect of certain elements of Closer-to-Nature Forest Management on biodiversity conservation and ecosystem health, and how they will affect other ecosystem services including wood production under different management conditions throughout Europe. This calls for more collective learning, experimentation and research.

“…This represents promising potential for its success. In the Karst it is often one of the dominant species, and it is also promising in gradual conversion by means of natural regeneration (Diaci et al, 2019). We expect that in the long term Quercus petraea might be the most successful of all of the planted species, although perhaps not the best quality.…”

Good survival of broadleaf tree species in a four-year-old plantation in the Slovenian Karst

Six broadleaf tree species (Celtis australis L. – Mediterranean hackberry, Quercus petraea (Matt.) Liebl. – sessile oak, Fagus sylvatica L. – European beech, Prunus avium L. – wild cherry, Juglans regia L. – Persian walnut and Acer pseudoplatanus L. – sycamore maple) were planted in 2012 in a trial in the Slovenian Karst on two sites differing in productivity to test their suitability for use in the conversion of old pine stands into ecologically more stable broadleaf forests and to investigate their possible response to the harsher growth conditions predicted in the future. The selected economically interesting tree species have higher timber quality than broadleaves which regenerate naturally (e.g., Ostrya carpinifolia, Fraxinus ornus, Quercus cerris). Measurements were taken in 2017, after four growth seasons. All planted species except Fagus sylvatica had a high survival rate. In total, 70% of all seedlings survived, which shows promising potential. The survival rate was higher at the site on flat terrain than at the site on a slope. Prunus avium was the most successful of all planted species in terms of survival rate, at 83%, and other measured parameters (height, height increment, stem diameter, vitality and quality), and Fagus sylvatica was the least successful, with a survival rate of only 20%. Celtis australis had the highest survival rate, at 87%. Acer pseudoplatanus had the largest differences in measured parameters between the more and less productive sites among all planted species. Quercus petraea showed high resistance to xeric conditions and is expected to be the most successful in conversions. All planted species except Fagus sylvatica show favourable initial potential for the future conversion of Karst pine forests.
