1. Cucujus cinnaberinus (Scopoli, 1763) at its terra typica in Slovenia : historical overview, distribution patterns and habitat selectionAl Vrezec, Špela Ambrožič Ergaver, Andrej Kobler, Andrej Kapla, Maarten De Groot, 2017, original scientific article Abstract: The saproxylic beetle, Cucujus cinnaberinus, has received increasing research attention in Europe since the adoption of the Habitats Directive and establishment of the Natura 2000 network. The history of the species has been investigated as well as the influence of abiotic and biotic variables on the distribution of C. cinnaberinus in Slovenia which is at the limit of its range and also terra typica for the species. The species was first described in 1763 by Joannes A. Scopoli in Carniola, a duchy of the Habsburg Monarchy. Today, most of the territory of Carniola is situated within Slovenia. C. cinnaberinus is particularly common in the eastern part of the country, but very scarce in the mountainous western part. According to historical and recent distribution patterns of C. cinnaberinus in the former Carniolan territory, the region of Ribnica-Kočevje in southern Slovenia is proposed as the most probable type locality of the species. Although the bulk of the C. cinnaberinus population in Slovenia is confined to the lowlands, the species has been found up to 1095 m a.s.l., albeit at a much lower abundance due to the influence of climate and forest structure. Although C. cinnaberinus is a quite an opportunistic species regarding host tree selection, it has been shown to exhibit a preference for Tilia, Populus and Robinia. It is suspected that the high abundance of C. cinnaberinus in lowland floodplain forests is due to the recent human-induced increase in preferred fast-growing and short-lived host trees, i.e. the planting of poplar trees and spread of invasive Black Locust (Robinia pseudoacacia) after the 1960s. In contrast, in montane forests, preferred host trees (e.g. Tilia) represent < 1 % of all growing stock. Although montane C. cinnaberinus populations are rare, they could still be important for the conservation of the species, since montane habitats cover the largest area within the species’ distribution range.

4. 250 let načrtnega usmerjanja razvoja gozda in 135 let usmerjanja populacij prostoživečih živalskih vrst v Trnovskem gozduEdo Kozorog, Peter Razpet, 2023, professional article Abstract: Pred 250-timi leti je bil narejen prvi gozdnogospodarski načrt za Trnovski gozd, ki je začetek načrtnega gospodarjenja z gozdovi v Sloveniji. Že ob koncu 18. stoletja so takratni gozdnogospodarski načrti vsebovali tudi podatke za lovne vrste v Trnovskem gozdu. V prispevku je predstavljen razvoj ključnih živalskih in rastlinskih vrst v Trnovskem gozdu prek kazalnikov, ki so sestavni del gozdnogospodarskih načrtov. Iz prikaza izhaja, da je bil razvoj nekaterih vrst zelo dinamičen in soodvisen, na kar se je treba pri usmerjanju razvoja stalno prilagajati. Izpostavljena je tudi težava pomanjkljivih podatkov o stanju nekaterih, zlasti ogroženih vrst ter posledično nezanesljivih ocen vzročnih povezav.

5. Phytosociological description of the dwarf mountain pine shrub community (Amelanchiero ovalis-Pinetum mugo) in the valleys of the Slovenian AlpsIgor Dakskobler, Mateja Cojzer, Andrej Rozman, 2023, original scientific article Abstract: We have expanded our knowledge of the localities, sites and distribution of the Amelanchiero ovalis-Pinetum mugo association in the Slovenian Alps. Based on phytocenological analyses, the shrub association belonging to the forest vegetation type Alpine mountain pine scrub was divided into two subassociations: peucedanetosum oreoselini and hylocomiadelphetosum triquetri. We also described four variants within the latter association.

6. Assessing the heterogeneity and conservation status of the Natura 2000 priority forest habitat type Tilio–Acerion (9180*) based on field mappingJanez Kermavnar, Erika Kozamernik, Lado Kutnar, 2023, original scientific article Abstract: Priority habitat types (HTs) within the Natura 2000 network are of the highest importance for conservation in Europe. However, they often occur in smaller areas and their conservation status is not well understood. One such HT is that of the Tilio–Acerion forests of slopes, screes and ravines (9180*). The Natura 2000 study site, Boč–Haloze–Donačka gora, in the Sub-Pannonian region of eastern Slovenia is characterized by a matrix of European beech forests and includes rather small, fragmented areas covered by Tilio–Acerion forests. The goal of this research was to examine the heterogeneity and conservation status of the selected HT through field mapping, which was performed in the summer of 2020. As the conservation of HT calls for a more detailed approach, we distinguished between the following four pre-defined habitat subtypes: (i) Acer pseudoplatanus-Ulmus glabra stands growing mostly in concave terrain, (ii) Fraxinus excelsior stands growing on slopes, (iii) Tilia sp. stands with thermophilous broadleaves occurring on ridges and slopes, (iv) Acer pseudoplatanus stands occurring on more acidic soils with an admixture of Castanea sativa. Field mapping information was complemented with the assessment of habitat subtype characteristics using remote sensing data. The results showed that habitat subtypes differed significantly in terms of area, tree species composition, forest stand characteristics, relief features and the various threats they experienced (e.g., fragmentation, tree mortality, ungulate browsing pressure). The differences between subtypes were also evident for LiDAR-derived environmental factors related to topography (i.e., terrain steepness and Topographic Position Index). This study provides a baseline for setting more realistic objectives for the conservation management of priority forest HTs. Due to the specificities of each individual habitat subtype, conservation activities should be targeted to the Natura 2000 habitat subtype level.
