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.

We investigated several aspects of windthrow that are relevant to our understanding and management of forest ecosystems. As an example, we used an extreme event in December 2017, when the strongest storm in recent history occurred in the Slovenian Dinaric High Karst. We examined influential factors such as soil properties, wind speed, precipitation and ecological consequences for the affected forests. Soil properties were measured around standing and fallen silver fir trees at all three research sites. Tree species composition in the regeneration was observed on plots with chemical and acoustic ungulate deterrents and on control plots without deterrents. Economic estimates of yield loss due to damage were calculated at the national level. A model of the potential threat from windthrow was also developed based on data collected from windthrow events and meteorological data over the past 20 years. Our results indicate that soil depth and mineral fraction depth were similar at sites with and without damaged trees and were not the determining factors for tree toppling. Plots with acoustic deterrents showed the most effective regeneration development, the least decline in silver fir and the greatest increase in noble hardwood seedlings, while plots with chemical deterrents showed the least browsing damage. The estimated economic loss of €16.1 million is 6.6% less than the harvest under normal conditions. The economic loss was relatively low due to the nature of the storm, with the predominant type of damage being uprooted trees with no damaged trunks. The windthrow hazard model revealed that a large number of consecutive events with strong winds in each section weakened the stand, which was subsequently knocked down during the next extreme wind and rainfall event.

This article discusses single-tree growth models, which have become an important tool for decision-making, management and strategic decisions in the field of forest management. In Slovenia, we have only recently begun systematic development in the field of forest modelling, which includes the development of a matrix population model, testing selected models from abroad and the development of individual model components. The goal of our work is to introduce the field of empirical single-tree models for modelling forest development on a larger scale. We provide a detailed overview of established methods for modelling individual components of tree models, such as radial and height growth, crown recession, mortality, and recruitment and regeneration. We evaluated the suitability of the selected models from the perspective of their applicability in Slovenia. We conclude that the SILVA, WEHAM, MASSIMO and CALDIS models have the greatest potential for use in Slovenia, as they are all suitable for the different forest types and mixed forests with different structure that prevail in Slovenia. In addition to testing the existing models, we propose the development of new models adapted to the heterogeneous and mixed stands in Slovenia. We also propose expanding the set of indicators in forest inventories and measuring additional tree characteristics, such as canopy characteristics, which would expand forest modelling opportunities in Slovenia. In the conclusions, we also discuss the potential use of machine learning in forest development modelling, as this type of model could represent the next generation of forest models.

The Forest Act allows vehicles to be driven in the forest outside of forest roads for the purpose of forest management or rescue of persons or property. The vehicles and machinery intended for these tasks are very diverse, both in their form and in the dimensions and quality requirements of the thoroughfares on which they move. The types of mechanization discussed include agricultural tractors, specialized forestry mechanisation, trailers on tractors, trucks, cars and construction machinery. By reviewing various databases, legal restrictions and our own experience, interval data on the mass and width of representative examples of each category were given. It was estimated that among forest owners, the most numerous mechanization was up to 200 cm wide, while among professional contractors and protection and rescue forces, the most numerous mechanization and vehicles were up to 230 cm wide. It was also found that mechanization and vehicles up to 230 cm wide can perform all forest management and protection and rescue tasks at least on a basic scale.

Urban and peri-urban forests are important habitats for maintaining biodiversity in cities. In this paper, we report a method for using hoverflies as biodiversity indicators in urban forest habitats. As a case study, forest habitats in three peri-urban and urban forests were assessed and compared to rural forests in Slovenia. Rožnik (Ljubljana) was chosen as the urban forest site, Mestni log (Ljubljana) and Brdo (Kranj) were chosen as the peri-urban sites, and eight sites were chosen in rural forests in different ecoregions in Slovenia. Forest hoverfly species richness and the species composition of different biological traits were compared between the peri-urban forests, urban forest and rural forest sites. In addition, species richness was assessed for changes in response to weather conditions between years. The number of species with the investigated traits in the urban and peri-urban forests was within the range of the number of species observed in the rural forests. The number of saproxylic species was higher in the urban forest but lower in the peri-urban forests compared to the rural forests. The proportions of species with different feeding modes and different development times were similar between the peri-urban, urban and rural forests. The proportions of species with development times of less than 2 months or more than 1 year and of predatory species were similar in the urban and peri-urban forests but higher in the rural forests. The species composition of the other biological traits differed between the peri-urban, urban and rural forests. Species richness and abundance displayed large differences in phenological patterns between 2012 and 2013; these differences are related to differences in the minimum temperature for these years. The results are discussed in relation to forest management in urban forests, the usefulness of hoverflies as a biodiversity indicator and possible extrapolation to other species groups.

Use of proper personal protective equipment, can reduce workload of forestry workers, depends on working conditions. To identify differences between protective clothing systems (summer, transitional, winter), a laboratory study using a cycling-ergometer was conducted. During the study, 9 different measuring devices were used, with which we were able to measure 8 psychophysical indexes. Research showed that there are significant differences between the clothing systems depended on certain indexes. Resistance of cycle ergometer (load) has influence on all psychophysical indexes. Despite the study, made only on one research person, results are showing usefulness for measuring selected psychophysical indexes, and they prove that usage of protective clothing systems has impact on forest worker.

Monitoring the development of forest wood assortment prices is important for successful strategic planning, especially in the event of sudden changes in the wood market and in the implementation of trade policy. Revenue from forest wood assortment sales remains the most important criterion influencing the activity of forest owners or managers in intensifying forest management. The article presents data sources for prices of forest wood assortments in Slovenia and selected European countries and describes the main features of individual methods of collecting roundwood prices. After reviewing each of the methods used to collect prices for forest wood assortments, it was found that they differ from each other. In order to monitor the roundwood market, it is necessary to know and consider the criteria for defining the individual or group of forest wood assortments that are included in the statistics. However, caution should be exercised when comparing prices between individual sources, as the naming and classification of forest wood assortments varies from country to country and, in some places, from region to region. The article also compares prices for quality class B spruce logs among five different data sources for Slovenia, Austria, Germany, and the Czech Republic.

The spatial variability of precipitation in Slovenia was evaluated using correlation decay distance analysis (CDD). CDD analysis essentially explores how the correlation between neighbouring stations varies according to distance. We analysed CDD for the period December 2009–November 2019 using only those meteorological stations (n = 160) with no missing values and operating at same location for the whole analysed period. For each meteorological station, we calculated the threshold distance at which the correlation between series is higher than 0.707 (r2 = 0.5). The results indicate that the highest spatial variability in precipitation is during summer (CDD = 50 km), followed by spring (CDD = 76 km), autumn (CDD = 120 km) and winter (CDD = 141 km), when the spatial variability is the lowest. The spatial variability of precipitation is similar in spring and autumn (with the lowest variability of precipitation in E and SE Slovenia), and it is lowest in S Slovenia in summer and in NW Slovenia in winter. The variogram map indicates anisotropy in the correlation decay distance for spring precipitation. Higher values of semivariance are evident in the NE-SW direction, while semivariance values in the SE-NW direction are much lower.

The main purpose of the current research was to determine the chemical structure of typical lignocellulosic residues generated in wood processing industries, fruit and vine growing activities, and the maintenance of green areas. Four characteristic groups of samples, e.g. wood sawdust, bark, tree prunings and the lignified residues of fruits were analysed for the content of ash, lipophilic and hydrophilic extractives, cellulose, hemicellulose and lignin. Gravimetric methods were used for the analyses, and the purity of individual isolated fractions was monitored by FTIR spectroscopy. The highest quantity of ash and low molecular weight extractive compounds was determined in bark and tree prunings, while concentrations of cellulose and total carbohydrates were highest in sawdust samples. Lignified fruit residues and bark proved to be rich sources of lignin. Because of their diverse chemical composition, all of the examined materials are potential feedstocks for the production of platform chemicals and other specific products within biorefinery processes.

The aim of the study was to review the legislation and legal framework for the cultivation of non-native tree species in Slovenian forests. In the EU, several legal instruments are relevant for the introduction, use and management of non-native tree species, e.g. the Council Directive on the marketing of forest reproductive material, the Habitats Directive and the Regulation on the prevention and control of the introduction and spread of invasive alien species. In Slovenian legislation, the area of their introduction and potential impact is regulated primarily by the Nature Conservation Act, but also important are the Decree on Special Protection Areas (Natura 2000 areas), the Forest Act, the Forest Reproductive Material Act, the Regulations on the Designation of Seed Areas and the Decree on Protected Wild Plant Species. According to the legislation, the cultivation of non-native trees is not prohibited in Slovenia for the implementation of forestry activities, immigration is allowed, and the introduction of new non-native species requires an appropriate procedure that includes an environmental impact assessment and is approved by the competent minister. Slovenian legislation thus provides opportunities for the cultivation of non-native tree species, which could be of crucial importance for the adaptation of forests to climate change due to their better resistance to biotic and abiotic factors, as well as of economic importance due to their faster growth and timber quality.
