Development and testing of an innovative model for managing ecosystems in the Rački ribniki–Požeg landscape park
Anže Japelj, Andreja Ferreira, Andrej Kobler, Anže Martin Pintar, Kaja Plevnik, Pia Höfferle, 2026, izvirni znanstveni članek

Povzetek: The article presents the process of designing and testing an ecosystem-based governance model (EBGM). The EBGM is an innovative and highly participatory approach to addressing management challenges in protected areas. The implementation of the EBGM makes it possible to define a management approach that seeks to balance the interests of various stakeholders, ensure the long-term availability of ecosystem services, and meet the conservation goals of nature protection in important areas. The study focused on Natura 2000 sites affected by climate change (altered precipitation patterns, higher temperatures, more frequent natural disturbances, the spread of invasive alien species, etc.) while also facing management challenges (conflicting stakeholder interests, lack of management capacity, preparation of management plans, etc.). The EBGM consists of six elements, representing phases in the search for shared governance solutions. It incorporates seven fundamental principles and three key management dimensions. The model was developed iteratively and tested in practice through two participatory workshops involving key stakeholders of the Rački ribniki–Požeg Landscape Park, which, at the time of the study, was undergoing a revision of its protection act and the preparation of a management plan. The outcomes of testing the EBGM included the establishment of a stakeholder network, an assessment of the park’s importance for nature conservation and provision of ecosystem services, an evaluation of past and future development trends, and the delineation of management zones for the entire area of the park. The EBGM is sufficiently flexible to be applied in other contexts and under different ecosystem management regimes.

Osutost drevesnih krošenj v Sloveniji po letu 1991 s poudarkom na letu 2024
Anže Martin Pintar, Pia Höfferle, 2025, izvirni znanstveni članek

Povzetek: Več kot 30-letno vsakoletno spremljanje osutosti dreves na istih ploskvah Raven I v okviru programa ICP Forests omogoča dragocen vpogled v dolgo časovno vrsto spremljanja vitalnosti drevesnih vrst, ki je še posebno aktualno v času podnebnih sprememb, ko so ekstremni vremenski dogodki vse pogostejši. V pričujočem prispevku predstavljamo rezultate spremljanja stanja osutosti drevesnih krošenj na ploskvah Ravni I v obdobju 1991–2024 v Sloveniji, s poudarkom na zadnjem letu meritev – v letu 2024. Od leta 1991 se je povprečna osutost povečala za 14,2 % (s 16,6 % na 30,8 %). V letu 2024 je povprečna osutost iglavcev znašala 31,5 %, pri listavcih pa 30,3 %. Časovna vrsta povprečne osutosti drevesnih krošenj za več kot 30-letno obdobje kaže, da se je v obdobju 1991–2000 stanje osutosti krošenj slabšalo, med letoma 2000 in 2013 pa je bilo razmeroma stabilno. Na začetku obdobja 2014–2020 smo zaznali veliko povečanje osutosti drevesnih krošenj (2,2 %) zaradi žleda leta 2014, sledilo pa je umirjanje negativnega trenda poslabševanja stanja, tj. povečevanja osutosti. Veliko povečanje osutosti (za 3,8 %) smo ponovno zaznali med letoma 2020 in 2022, na kar je vplivala poletna suša v letu 2022, vplivale pa so tudi različne ujme, kot so vetrolomi in gradacije podlubnikov. V zadnjih dveh letih smo zaznali stagnacijo stanja osutosti.

The impact of sanitary felling during large-scale disturbances on regulating ecosystem services in norway spruce-dominated Pre-Alpine beech forests of Slovenia
Anže Martin Pintar, Andreja Ferreira, Pia Höfferle, Anže Japelj, 2025, izvirni znanstveni članek

Povzetek: Ecosystem services (ES) are closely linked to nature-based solutions, which can mitigate the negative impacts of climate change or provide society with direct tangible and intangible benefits. In the context of a changing climate, it is essential to preserve these services despite increasing disturbances. In this study, we analysed changes in the structure and composition of the Jelovica forest complex (NW Slovenia) over the past two decades and assessed the provision of key regulating forest ES—specifically, soil erosion control, regulation of surface and groundwater flows, and regional climate regulation. The area has historically seen the artificial promotion of Norway spruce and, in recent decades, has been increasingly affected by large-scale disturbances and bark beetle outbreaks. We examined how these climate-related disturbances have influenced the availability of regulating ES. Over the past twenty years, the share of spruce in the growing stock in the Jelovica area decreased from 67% to 62%. We compared structural and compositional changes between two periods, 2001–2009 and 2015–2023, based on available forest management data. In both periods, mature stands were the dominant developmental stage. In the northwestern part of the Jelovica plateau, where extensive sanitary felling was carried out, the proportion of sapling stands increased significantly—unlike in other parts of the plateau. Areas affected by extensive sanitary felling exhibited statistically significantly lower evapotranspiration and reduced soil erosion control capacity, as well as higher levels of groundwater recharge, compared to other areas.
