Abstract: In recent years, Europe has experienced an unexpectedly high frequency of natural disturbances. Private forest owners (PFOs), who manage a significant proportion of European forests and have diverse objectives and approaches to forest management, play a crucial role in salvage logging. The aim of this study was to (i) categorise PFOs based on their forest management objectives, experience with regular forest management, and responses to natural disturbances, and (ii) propose policy implications for particular PFO groups to improve salvage logging operations and meet legal requirements. A survey was conducted among a random sample of PFOs whose forests were affected by natural disturbances (n = 547). The survey data were analysed using K-means cluster analysis, and three groups of PFOs were identified. The outsourcing-oriented managers (32%) responded most strongly to natural disturbances, with 96.0% carrying out salvage logging. This highly co-operative group often relies on forest contractors and demonstrates the highest commitment to performing forest management activities among the three groups. The self-reliant managers (42%) also responded strongly (92.6% carried out salvage logging) and are characterised by a strong preference for performing the work themselves. The group of less active managers (26%) included the highest proportion of PFOs who did not conduct salvage logging (19.0%) and those with no previous forest management experience (12.0%). Despite these differences, common policy instruments based on smart regulation principles are proposed to promote efficient salvage logging. The results may contribute to the holistic transformation of forest policy and management in response to the current challenges posed by large-scale natural disturbances.

Abstract: Invasive alien species (IAS) pose a signiicant threat to forest ecosystems by disrupting ecological networks and competing with native species. Forest habitat patches and corridors designed to enhance connectivity and biodiversity can unintentionally promote the dispersal of IAS, further compromising the ecological integrity of the forest ecosystem. This chapter discusses two main aspects related to IAS and forest connectivity: (1) the spread of IAS in the landscape and their impacts on native species and (2) the consequences of IAS on forest connectivity. Effective management of IAS is crucial to improve connectivity for native species while restricting the spread opportunity for aliens and preserve biodiversity. Ideally, a site-speciic risk analysis should precede conservation or restoration efforts, determining the potential impact of IAS on the respective habitat patch’s structural and functional connectivity, and vice versa. Furthermore, this chapter explores management strategies to control IAS, including physical removal, biological control, and monitoring. Citizen involvement and remote sensing play vital roles in supporting management actions, IAS detection and long-term monitoring, and habitat connectivity. Including stakeholders such as forest owners and managers in such actions ensures a collaborative approach to safeguarding forest ecosystems from the threats posed by IAS.

Abstract: The heterobranch fauna recorded to date in the Slovenian part of the Adriatic Sea was reviewed and analysed in order to present an updated inventory. The ecological traits and zoogeographical affiliation of the recorded heterobranchs were also analysed. The new data revealed that the heterobranch fauna in the area consists of at least 157 species with the majority being nudibranchs (61.4%). The bulk of heterobranchs were considered as Atlanto-Mediterraneans. Heterobranch diversity was found to be significantly related to the number of sampling events. The spatial pattern of heterobranch species and their composition structure in parts of the study area were linked to specific human-impacted areas (HIAs) such as coastal wetlands, ports, and mariculture facilities. Better examination of less investigated environments, new sampling techniques, and citizen science involvement will doubtlessly increase the numbers in this checklist.
