Abstract: The Environmental Impact Classification for Alien Taxa (EICAT) is an important tool for biological invasion policy and management and has been adopted as an International Union for Conservation of Nature (IUCN) standard to measure the severity of environmental impacts caused by organisms living outside their native ranges. EICAT has already been incorporated into some national and local decision-making procedures, making it a particularly relevant resource for addressing the impact of non-native species. Recently, some of the underlying conceptual principles of EICAT, particularly those related to the use of the precautionary approach, have been challenged. Although still relatively new, guidelines for the application and interpretation of EICAT will be periodically revisited by the IUCN community, based on scientific evidence, to improve the process. Some of the criticisms recently raised are based on subjectively selected assumptions that cannot be generalized and may harm global efforts to manage biological invasions. EICAT adopts a precautionary principle by considering a species’ impact history elsewhere because some taxa have traits that can make them inherently more harmful. Furthermore, non-native species are often important drivers of biodiversity loss even in the presence of other pressures. Ignoring the precautionary principle when tackling the impacts of non-native species has led to devastating consequences for human well-being, biodiversity, and ecosystems, as well as poor management outcomes, and thus to significant economic costs. EICAT is a relevant tool because it supports prioritization and management of non-native species and meeting and monitoring progress toward the Kunming–Montreal Global Biodiversity Framework (GBF) Target 6.

Abstract: Background and objectives: Successful policy implementation relies on understanding stakeholders’ willingness to contribute to policy goals. The EU Green Deal, with strategies on forests, biodiversity, and the bioeconomy, also depends on the performance of the forestry sector, including a significant portion of privately owned forests. Materials and methods: We conducted a nationwide survey among a sample of 341 private forest owners in Slovenia (total population of 424,086). The online questionnaire had three sections: (1) knowledge and priorities regarding ecosystem services and the bioeconomy, (2) a discrete choice experiment for eliciting preferences concerning the implementation of activities supporting strategic goals originating from EU Green Deal policies, and (3) socio-economic data and future forest management objectives. Results: The results indicated heterogeneity in preferences for performing activities on private forest lands to enhance specific forest ES that contribute to policy goals. More than half of the respondents (57.6%) exhibited a reluctance to implement activities and were skeptical of higher compensation payments, whereas the rest expressed an inclination towards changing their forest management. Conclusions: Slovenia’s private forest owners appear to be heterogeneous in their willingness to participate in a hypothetical ES enhancement scheme that could contribute to some EU Green Deal goals. Policymakers must recognize intrinsic motives and social norms that affect the willingness of forest owners to be engaged to increase the acceptance of solutions.

Abstract: Železniški transport je okoljsko in ekonomsko sprejemljivejši od drugih vrst kopenskega transporta, vendar lahko negativno vpliva na prostoživeče živali, saj pomeni oviro za njihovo gibanje (barierni učinek) ter neposredno povečuje umrljivost zaradi trkov z vlaki. Zaradi tovrstnih vplivov je smiselno načrtovati in implementirati omilitvene ukrepe, ki zagotavljajo ekološko povezljivost in zmanjšujejo umrljivost prostoživečih živali na območju železniške infrastrukture. Ukrepi morajo biti usmerjeni predvsem k preprečevanju vstopanja in zadrževanja živali na območju železniških tirov, saj se vlaki praviloma ne morejo izogniti trku. Še posebej primerni so omilitveni ukrepi, ki zmanjšujejo število trkov in ne povečujejo bariernega učinka. V preglednem članku smo se osredotočili na ukrepe, ki so bili obravnavani oz. implementirani na območju železniške infrastrukture in na novejše raziskave, v okviru katerih so preverjali možnost uporabe alternativnih omilitvenih ukrepov, npr. opozorilnih sistemov, testiranih v Kanadi in na Švedskem. V drugem delu prispevka predstavljamo predlog protokola za zagotovitev migracijskih koridorjev na območju železnice, ki smo ga oblikovali na podlagi relevantne tuje literature in lastnih izkušenj, pridobljenih z načrtovanjem in spremljanjem ukrepov za zmanjšanje povoza prostoživečih živali (s poudarkom na parkljarjih) na cestah, hitrih cestah ter avtocestah in z analizo povozov na območju slovenske železniške infrastrukture v izbranem petletnem obdobju.
