Povzetek: etween 1st and 6th June 2023, we conducted floristic research on sev-eral sites in the upper Neretva River valley and along Zalomka River at Nevesinjsko Polje. We recorded 933 taxa in total; 897 plant taxa including 125 bryophytes were found at 51 localities in the upper Neretva River val-ley, and 200 plant taxa, including 32 bryophytes, were found at 11 sites in the Zalomka River valley. Among the registered taxa, 39 taxa are endemic to the Balkan Peninsula, 56 are listed in the List of endangered and rare taxa of Bosnia and Herzegovina, 27 are on the Red List of the Federation of Bosnia and Herzegovina, and 95 taxa are protected in the Republic of Srpska. We also registered several species new to the flora of Bosnia and Herzegovina. Among Angiosperms these were Barbarea intermedia, Lamium hybridum, Myosotis sicula and Poa ursina, and among bryophytes Fissidens gracilifolius, Grimmia dissimulata, Plagiomnium ellipticum, Schistidium robustum, Sphenolobus minutus, Tortella fasciculata and T. pseudofragilis. Our study reveals the high nature conservation value of the upper Neretva and Zalomka River valleys that should be protected for future generations. In addition, further systematic research of the flora of Bosnia and Herzegovina is needed

Povzetek: The fan mussel Pinna nobilis is the largest bivalve species in the Mediterranean Sea and provides numerous ecosystem services. It is classified as critically endangered by IUCN (International Union for Conservation of Nature) due to severe mass mortality events throughout the Mediterranean. The aims of this work are as follows: (i) to assess the current recruitment potential of the species, (ii) to enhance recruitment by keeping juveniles in controlled conditions before releasing them back into the sea, and (iii) to assess the health status of recruits. In the period 2022–2023, larval collectors were set up in the Gulf of Trieste as part of the LIFE Pinna project. The collected individuals were kept in aquaria in two different facilities under different conditions: (a) a closed system with constant water temperature, live phytoplankton, and commercial food and (b) an open system with ambient seawater temperature and commercial food. A clear temporal and spatial variability in recruitment was observed: 13 recruits were found in 2022 and 50 recruits in 2023. The live specimens were between 0.5 and 8 cm in size upon collection and larger in 2023. The growth and survival rate did not differ significantly between the two systems, but the average monthly growth and survival rate were related to the initial size of the juveniles.

Povzetek: Maintaining the conservation status of habitat types such as the ravine forests (Tilio-Acerion) assessed in this study is a priority of the European Natura 2000 network. Ravine forests often occur in smaller, fragmented areas, but are widely distributed throughout European forests. Reliable indicators of the conservation status of Natura 2000 habitats, which support monitoring and reporting under Article 17 of the Habitats Directive, are often not available. Therefore, we tested a set of 161 structural and compositional variables as potential indicators of the conservation status of close-to-nature managed ravine forests in a Natura 2000 site in eastern Slovenia. The studied forests ranged from Acer pseudoplatanus-dominated stands to those dominated by Fraxinus excelsior or Tilia species. Most forests were classified as having either a favourable or inadequate conservation status. The main pressures included game browsing and mortality of the key tree species, primarily caused by invasive alien fungi. Favourable conservation status was associated with less intensively managed Tilia-dominated stands on rocky ridges and steep slopes. It was also linked to higher tree layer cover, particularly of Acer pseudoplatanus, in well-preserved forest stands. Conversely, indicators of bad conservation status were associated with Fraxinus excelsior-dominated stands that had been severely affected by invasive alien fungi, resulting in increased volumes of standing and lying deadwood. The resulting tree mortality created more open stand canopies with increased light availability at the forest floor, as indicated by the higher number of plant species in the herb and shrub layer. The conservation status of ravine forests is likely to be increasingly threatened by the adverse effects of climate change, including pests and disease outbreaks and other disturbances. To ensure the continued favourable conservation status of ravine forests, it is essential to monitor key indicators and apply appropriate forest management measures.

Povzetek: The genetic diversity of forest trees, as provided by Forest Genetic Resources (FGR) and being the basis for the production of Forest Reproductive Material (FRM), is fundamental for maintaining forest resilience, adaptability, health, productivity, and biological diversity. Despite their importance, stakeholder governance of genetic diversity remains under-studied. This study aims to address this gap by mapping the forest stakeholder landscape FGR governance. Using the Quadruple Helix Approach, we categorised stakeholders into academia, industry, government, and civil society identifying relevant sub-communities. The mapping process involved iterative revisions through expert consultations, workshops, and literature scoping. Results show that the FGR sub-community is situated between strict conservation efforts and applied forestry, supporting both genetic conservation and productive forest management. The FRM sub-community, dealing specifically with the production and deployment of FRM, prioritises tree breeding, seed production, and afforestation/reforestation programmes. Meanwhile, the Protected Forests (PF) sub-community focuses on strict nature conservation, advocating minimal human intervention while facing pressures from resource extraction, tourism, and land-use conflicts. The diverging attitudes and values of close-to-nature forest management, intensive forestry, and strict protections, respectively, exist within same stakeholder groups, as well as among different ones, and are spanning all sub-communities. The study uncovers key tensions such as competing land-use priorities between forestry, agriculture, infrastructure and energy sectors, limited flow of knowledge between stakeholder categories and governance misalignments between local, national, and international regulations. The findings are particularly relevant for policymakers, forest managers, forest nurseries, conservation organisations, and industry stakeholders to balance conservation with sustainable forest utilisation. By integrating stakeholder perspectives and highlighting key governance challenges, this study shows where a common ground can be found and where divergent opinions are strong, opening the way for more integrated strategies and policies

Povzetek: Understanding public attitudes toward wildlife is crucial for the success of conservation efforts, particularly for species that might elicit mixed perceptions. For the first time in Slovenia, we conducted a study on attitudes and knowledge about the Eurasian lynx among primary, lower and upper secondary school pupils. Participants between the ages of 9 and 19 took part in the survey (N = 1312). The aim of the study was to determine the general acceptance and knowledge of the lynx and identify the key factors that influence the formation of attitudes and knowledge. The survey results show a good acceptance of the species among the younger generation and a high level of support for its conservation. A higher amount of knowledge was positively associated with less fear of the species, more interest in learning and higher support for conservation. Living in a region with a permanent lynx presence was associated with less fear and more interest in learning about the species. No differences in acceptance and support for lynx conservation were detected between regions with or without the permanent presence of the species. Year of education was positively associated with the amount of knowledge about lynx, while gender was partially associated with the amount of fear but mainly with support for conservation. Against this background, we provide guidance for planning future communication and education activities for the long-term conservation of the species.
