AB  - The paper investigates the natural regeneration of downed deadwood in the Janj primeval forest. The old-growth forest is located in the southwestern part of the Republic of Srpska, which is dominated by dolomite geological base on which cambial soils were formed. The climate is perhumid and mountainous and the plantation belongs to the Piceo-Abieti-Fagetum community. The hectare contains 517 live trees with a total basal area of 53.0 m2/ha and a volume of 876 m(3)/ha. Twenty six downed deadwoods classified into three different degrees of decay were included in the study, where fir and spruce seedlings were found to be predominant and beech seedlings were rarely represented. The first degree of decay includes 7 (26.9 %), the second 8 (30.7 %), and the third 11 (42.3 %). The total volume of deadwood is 110.82 m3/ha with an average volume per tree of 4.2 m3/ha. The total number of seedlings on fallen dead trees is 836 seedlings (Abies alba - 89.59 %, Picea abies - 10.17 %, Fagus silvatica - 0.24 %).Fir seedlings are found on 25 fallen trees, spruce on 18 fallen trees, and beech on 2 fallen trees. Regarding quality, on average fir seedlings are better than spruce seedlings, but both species show a lot of senescence and very small size of current height increment. Most seedlings belong to the third quality class (fir - 46.2 %, spruce - 61.1 %), followed by second class (fir - 34.6 %, spruce -22.2 %) and third class (fir - 19.2 %, spruce - 16.7 %). The total number of seedlings was found to have a statistically significant difference in the amount of downed deadwood depending on the degree of decay, and the number of seedlings depended on the degree of tree decay. The number of seedlings increased with increasing volume and length of rotten trees.

AB  - Natural regeneration of sessile oak forests is a complex process whose final outcome is influenced by numerous factors. The initial phase of development of sessile oak seedlings stands out as the most critical period in the process of natural regeneration of sessile oak forests. As the available light and competition from the accompanying woody species and ground vegetation are some of the main predictors of the success of sessile oak forest regeneration, this paper presents the results of studying the influence of these factors on the regeneration dynamics and development of sessile oak seedlings. The research was conducted in sessile oak forests in northeastern Serbia in the period from 2015 to 2020. At the end of the growing season each year, the following data were collected on 180 smaller sampling plots of 1 m(2) in different conditions of canopy openness: the number, height, and root collar diameter of sessile oak seedlings. Also, the percent cover of competing woody species and ground vegetation was estimated on these sample plots. The obtained results indicated that the success of sessile oak forest regeneration largely depends on the initial number of sessile oak seedlings and silvicultural treatments during the rejuvenation period, which determine the microclimatic conditions in the stand and control the competing vegetation. They also indicate that with an increase in the available light, the impact of the competing vegetation on the dynamics of regeneration and development of sessile oak seedlings is less pronounced. Accordingly, as young sessile oak seedlings need a large amount of light for survival and development, it is necessary to increase the available amount of light intensively in a short period of time (six-eight years) by reducing canopy openness and thus providing optimal conditions in which sessile oak seedlings can gain an advantage over the competing vegetation.

AB  - The research was carried out in primeval forest stands of beech, fir and spruce (Piceo-Abieti-Fagetum illyricum) on brown dolomite soils (Janj) and dominantly shallow limestone soils (Lom). The diameter structure is typical for primeval forests with the participation of large trees in which physiological weakening is visible, especially in the Lom primeval forest. At the same time, the stands are characterized by the specifics of the transition from the terminal to the initial development phase, with a very pronounced lower floor of the stands where beech and fir dominate. Significant differences in the size of the diameter increment are characteristics for fir, which in the Lom primeval forest has a significantly higher diameter increment at the same diameters than in Janj. The current diameter increment of fir in Janj is 2.3 mm/year and in Lom 4.5 mm/year. The average current thickness growth of spruce in Janj is 0.2 mm higher on average than in Lom and amounts to 2.9 mm/year. The current thickness growth of beech in Lom is significantly higher (4.9 mm/year) than in Janj (2.3 mm/year). The average time of passage is the highest for fir in the Janj primeval forest and for the whole stand is 45 years, and the lowest for spruce in the Lom primeval forest 22 years. Beech trees in the lowest diameter classes have a significantly shorter time of passage than fir and spruce. Fir in the Janj forest has an average relative age of 85 years higher than in Lom. Spruce shows the largest difference in relative age between primeval forests in thinner diameter classes, and unlike fir, the difference in age decreases with increasing diameter.

AB  - The paper presents the results of research on competitive relations between sessile oak seedlings and the most important competing species of woody vegetation, as well as ground flora that grows under a shelterwood, after the preparatory-seed cut of the shelterwood cutting. The research was conducted in sessile oak (Quecus petraea /Matt./Liebl.) stand in the area of northeastern Serbia. The studied stand is located at 320 to 350 m above sea level, with a slope up to 25° and western exposure. In terms of phytosociology, the stand is defined as an association of sessile oak with hairy sedge (Carici pilosae – Quercetum petraeae B. Jov. 1989). After the preparatory-seed cut, 124 trees per ha remained in the stand, with a basal area of 11.9 m2/ha and a volume of 129.1 m3/ha. The obtained results in the paper indicate the competitive relations between sessile oak and the most important competing woody species, as well as the species of ground vegetation. The most common competing woody species are silver linden (Tilia tomentosa Moench.) and hornbeam (Carpinus betulus L.), while other species (Fraxinus excelsior L., Fraxinus ornus L., Crataegus monogyna Jacq., Acer campestre L., Cornus mas L.) are represented individually. In addition to a significant presence, competing species of woody vegetation are characterized by very intensive development, which significantly reflects on the presence and development of sessile oak seedlings. In contrast, eight-year-old sessile oak seedlings have outgrown blackberries in the studied stand, which no longer competes with them. The obtained results indicate that during the regeneration of sessile oak forests, special attention must be focused on the presence and dynamics of the development of competing vegetation, as well as that the success of the regeneration largely depends on controlling this factor.

AB  - The paper presents the results of a study on the regime of light and regeneration in a pure sessile oak stand in 'Fruska Gora' National Park in Serbia. Pure sessile oak stands cover 3960.73 ha or 17.6% of the area. The study stand is ecologically classified as the forest of sessile oak with fescue (Festuco drymeiae - Quercetum petraeae Jank. 1974) on acid brown and illimerised soil over sandstone. The 96 year-old stand is even-aged and vegetative. It is located on east and west facing slopes at an altitude of 450 m, with the slope inclination of 32 degrees. The starting hypothesis of this paper was that light regime has significant effects on the success of sessile oak forest regeneration. Data collection was performed in early July 2008. The study of regeneration elements (seedling number, height and quality) was conducted at the end of the growing season at the seedling age of 3. Light conditions that arc most favorable for regeneration include the intensity of illuminance between 5000 Lx and 10000 Lx, i.e, 1 1,3% to 22.6% of full daylight. The number of seedlings and their spatial distribution on the regeneration plot are in these specific site and stand conditions affected by the light regime of the area, making light most decisive, but not the only factor affecting their spatial distribution.

AB  - The paper studies the influence of the degree of canopy closure and light regime on the natural regeneration of mixed stands of fir and spruce in the area of Sitnica - in FMA "Mrkonjićko" Republic of Srpska. Stand estimation elements were measured using FieldMap technology. The method of hemispherical photographs and their processing using the Gap Light Analyzer (GLA) program were used to determine the light regime and the degree of canopy closure. The obtained parameters of the light regime (direct, diffuse, and total light), as well as the obtained values of the degree of canopy closure, were correlated with seedlings characteristics. The correlation method and regression analysis were applied. The obtained number of seedlings is satisfactory, and the new growth is mostly suppressed. The largest area of the stand has either a complete or dense canopy. The light intensity decreases with the increasing degree of canopy closure, but this correlation is the strongest in diffused light.

AB  - Old-growth forests are spontaneously developed forest ecosystems without direct human influence in which only natural processes take place. In this study we analyzed the structural sustainability of beech-fir-spruce old-growth forests on dolomite and limestone in the Bosnian Dinaric Mountains. The field work was carried out on permanent experimental plots of 1.0 hectare in size. Thereby, the diameters (d(1.30)) and the height (h) of all trees within the plots were measured. Based on the available literature, we hypothesized that the structure of old-growth forests provides sustainability through tree-size demographic equilibrium. Thus, the data collected were used to test possible differences between the actual and the theoretically balanced structure in the studied old-growth forests. Statistically significant difference in the actual structure between the two old-growth forests on limestone and dolomite was determined. However, both of them exhibited sustainable diameter distributions. These results point to the importance of preserving old-growth forests for future research as they exemplify the tree-size demographic sustainability and can thus serve as an appropriate reference to managed forests. Concretely, certain structural attributes from old-growth forests could be embedded into the management objectives for increased resilience of managed forests.

AB  - The data on forest fires in Portugal in the period 1980-2015 were used in the research: the annual number of forest fires, the annual burned area and the average burned area per fire. Increasing trend of the annual number of forest fires (statistically significant at p  lt = 0.01), nonsignificant increasing trend of the annual burned area and decreasing trend of the average burned area per fire (statistically significant at p  lt = 0.01) were recorded. Portugal is the most endangered country by forest fires in comparison with the other European countries. During the research period, fires in Portugal covered 23.6% of the total burned area in five the most affected European countries (Portugal, Spain, France, Italy and Greece). In the research of the connection between forest fires and the Atlantic Multidecadal Oscillation (AMO) Pearson correlation coefficient (R) was used. Monthly, seasonal and annual values of the AMO index were used in calculations. All R values recorded for the annual number of fires were positive and statistically significant at p  lt = 0.01. The highest values were recorded for August (0.543) and for summer (0.525). With the annual burned area all R values were also positive and the highest one on the seasonal level was for summer (0.359). With the average burned area per fire all R values were negative (-0.428 was recorded for winter). The results of the research could be applied in the fire danger forecast for periods of several months. Other climate indices should also be considered in future research.

AB  - The paper presents the most important data on temperature and other microclimate conditions (solar radiation and light regime) in the 127 year old even-aged pure sessile oak forest in the National Park "Fruska Gora" in Serbia. Data collection was conducted in July 2008, using an automatic weather station "WS-GP1" and a lux meter with a selenium photocell. The study stands are located on the east and west facing sides of a ridge at an altitude of 475 m. The slope inclination is 27 and 32. The canopy is sparse to complete (0.6-0.7). The paper presents comparative research results for the eastern and western aspect, which are further compared with the data from the reference weather station "Rimski Sancevi". The intensity and trend of microclimate changes depend on the type offorest, its structure, geographical location, canopy closure and other features. Microclimate research results indicate that during the research period the maximum air temperature of the eastern aspect was 24.8 degrees C, which was 3.6 degrees C below the maximum measured at the reference station. The maximum air temperature of the western aspect amounted to 31.0 degrees C, which was 2.8 degrees C below the value measured in the open. The maximum total solar radiation of the eastern aspect was 769 W/m(2) (at 11.08), and 634 W/m(2) (at 15.31) of the western. The research determined that the east-facing stand had the light intensity of 6,766.3 Lx/m(2), while the light transmission coefficient amounted to 14.8%; the west-facing stand had the light intensity of 9,213.8 Lx/m(2) and the light transmission coefficient of 19.3%.

AB  - The basic physical properties of spruce wood from plantations in the surroundings of Banja Luka were researched. The dependence of growth ring diameter and wood density, density, volume porosity, shrinkage, fibre saturation point and absorption of moisture were analysed on three trees average age about 16 years. The data for breast height and for all specimens from breast height to 9.3 m were statistically processed. The research and analysis of the basic physical properties of plantation-grown spruce wood shows that the effect of growth ring diameter on the density is negative and that the dependence is logarithmic, which confirms the previous results. Average value of wood density is lower than the usual value reported in references. Average value of radial shrinkage is 3.90%, and tangential 8.10%. This research confirms the linear dependence between the nominal density and volumetric shrinkage of spruce wood and that density has a negative effect on the coefficient of surface anisotropy. At breast height, average value of the coefficient of surface anisotropy is 2.16, volume porosity 72%, and fibre saturation point 32.6%. Average rate of absorption is 3.42% per day, for the first 7 days, and 0.12% per day for the last 30 days. The study results were compared to the results reported by other authors.

Izvršeno je i poređenje rezultata ispitivanja sa rezultatima drugih autora., The basic physical properties of spruce wood from plantations in the surroundings of Banja Luka were researched. The dependence of growth ring diameter and wood density, density, volume porosity, shrinkage, fibre saturation point and absorption of moisture were analysed on three trees average age about 16 years. The data for breast height and for all specimens from breast height to 9.3 m were statistically processed. The research and analysis of the basic physical properties of plantation-grown spruce wood shows that the effect of growth ring diameter on the density is negative and that the dependence is logarithmic, which confirms the previous results. Average value of wood density is lower than the usual value reported in references. Average value of radial shrinkage is 3.90%, and tangential 8.10%. This research confirms the linear dependence between the nominal density and volumetric shrinkage of spruce wood and that density has a negative effect on the coefficient of surface anisotropy. At breast height, average value of the coefficient of surface anisotropy is 2.16, volume porosity 72%, and fibre saturation point 32.6%. Average rate of absorption is 3.42% per day, for the first 7 days, and 0.12% per day for the last 30 days. The study results were compared to the results reported by other authors.",
