AB  - This paper aims to improve the methodology and results accuracy of MEDALUS model for assessing land degradation sensitivity through the application of different data detail levels and by introducing the application of Ellenberg indices in metrics related to vegetation drought sensitivity assessment. For that purpose, the MEDALUS model was applied at 2 levels of detail. Level I (municipality level) implied the use of available large-scale databases and level II (watershed) contains more detailed information about vegetation used in the calculation of the VQI and MQI factors (Fig. S6). The comparison was made using data based on CORINE Land Cover (2012) and forest inventory data, complemented with object-based classification. Results showed that data based on forest inventory data with the application of Ellenberg's indices and object-based classification have one class more, critical (C1 and C2) and that the percentage distribution of classes is different in both quantitative (area size of class sensitivity) and qualitative (aggregation and dispersion of sensitivity classes). The use of data from Forest Management Plans and the application of Ellenberg's indices affect the quality of the results and find its application in the model, especially if these results are used for monitoring and land area management on fine scales. Remote sensed data images (Sentinel-2B) were introduced into the methodology as a very important environmental monitoring tool and model results validation.

AB  - Land degradation is a complex issue caused by diverse drivers, each of which should be considered in the analysis of land sensitivity to degradation. This study identifies the areas most sensitive to land degradation in the Grdelica Gorge and Vranjska Valley, which are unique in terms of natural and socioeconomic conditions. Land-use changes and inappropriate land management have led to serious degradation in this region. The flexible and multifactorial approach of the Mediterranean Desertification and Land Use (MEDALUS) model allowed comprehensive land degradation sensitivity analysis in the study area. The main factors driving soil degradation were assessed by estimating climate quality index, soil quality index, and vegetation quality index, and the main socioeconomic indicators by management quality index and social quality index. The results showed that forest cover is the main factor to contrast land degradation, and even minor adverse changes in forest characteristics, such as structure, canopy cover, health, and quality, could trigger degradation processes. The vegetation quality index was defined in terms of the current vegetation???s capacity to protect soil from erosion, drought resistance, and fire risk. Detailed data on forest vegetation cover was obtained from the National Forest Inventory (NFI). The environmentally sensitive area (ESA) index generated through the analysis classified 26.11% of the total study area as critical, 69.53% as fragile, and 2.70% as either prone to or unaffected by degradation processes. According to the ESA index, the areas covered by forests with optimal species composition and high canopy cover were the least susceptible to degradation. The areas under intensive agricultural production without any application of conservation measures were the most susceptible to degradation. Future strategies for optimal land-use patterns are discussed, such as the intergration of woody species in croplands to protect soil against degradation and meet human needs in the areas prone to degradation.

AB  - The aim of this paper is to analyze the effect of different degrees of mixing on the diversity structure in stands left to spontaneous development. The research included two communities of species endemic to the Balkan Peninsula-the Serbian spruce (Picea omorika Pancic Purk.) and the Macedonian pine (Pinus peuce Griseb). Data from eight sample plots were used in the research. The changes in diameter and height structure, spatial arrangement of trees, and diameter differentiation were analyzed. The analyzed parameters of structural diversity show relatively low to moderate values. Results showed an increase in mixing was reflected in the width and shape of distributions. A spatial analysis of stands with a higher degree of mixing showed a tendency towards a random to regular distribution of individuals, in contrast to stands with a lower degree of mixing which showed a tendency towards a clump distribution. The pronounced species' dimensional and spatial diversity confirms their importance to the condition of modern forest management. Significant differences in the change of structure are shown by stands with a share of admixed species of above 20% by volume. The obtained results refer to stands left to spontaneous development, suggesting than an active research and management approach must be assumed to realize the goal of protecting rare forest ecosystems.

AB  - This study was mainly aimed at constructing polymorphic site index curves for beech in the central (Rudnik mountain - RU, about 15,000 ha) and eastern (Zagubica - ZA, about 7,000 ha) part of its distribution in Serbia. To obtain suitable height-age data and evaluate the best-fit growth model we used 107 felled dominant beech trees. The Korf, Korsun and Chapman-Richards growth functions per site class were first parameterized and then mutually compared with respect to residual statistics and the significance of their parameters. They were additionally parameterized in line with empirical data on the value and age of the culmination of current annual height increment (CAI(h)). The obtained results indicated that the Chapman-Richards growth function showed the best results both by statistical (residuals standard error, significance of the parameters, distribution of residuals, and homosccdasticity) and by empirical criteria (the CAI(h) culmination time, the maximal values of the CAI(h), and the attained height of trees at a certain age) of the height-age beech modelling in the analyzed regions. The obtained polymorphic site index curves which classify sites with regard to their productivity can be very helpful in planning appropriate silvicultural treatments, and for decision-making in forest management planning, forest policy and ecology and, consequently, in the sustainable management of beech forests in Serbia and some neighbouring countries with a similar forestry sector development.

AB  - The recent research has indicated that restoration of old-growth attributes such as large-sized living trees and snags contributes to sustaining biodiversity on the landscape level. The extent to which these attributes are restored, maintained, or diminished by total salvage logging, selection silviculture, and strict protection has been partly investigated in the past. However, studies examining the influence of partial salvage logging are largely absent. Thus, we compared long-term structural and compositional changes in three montane beech-fir-spruce stands in Serbia that were exposed to different management regimes for five decades (partial salvage logging, selection silviculture, and strict protection). Tree species composition of partly salvaged stand and selection stand significantly differed from that in the adjacent unmanaged stand. However, the diameter distributions of compared stands often exhibited the same structural forms in certain periods, despite the greater share of large-size trees in the unmanaged stand. The study indicated that managing for old-growth attributes such as large trees may be possible by applying not only rotated sigmoid and negative exponential structures, but also the increasing-q diameter structure as high basal areas in studied beech-fir-spruce stands did not impair the ingrowth of young trees when conifers dominated the upperstory. The study further revealed that partial salvaging may serve as a sound alternative to promoting old-growth attributes such as large veteran trees and snags.

AB  - Old-growth forests play an important role in getting an insight into processes that occur in nature, and consequently in the implementation of those insights through close-to-nature forest management. A segment of familiarity with the above processes is knowledge of the structural and production characteristics of the investigated old-growth forests. The research described in this paper was conducted in beech forests, in a total of 13 sample plots distributed in several mountainous regions of Serbia. Initially, the shape of diameter and height curves was used for the structural definition of the investigated forests, and the results were tested on the basis of the ages of individual trees. In addition, forest productivity was estimated on the basis of the achieved volume, current volume increment and increment intensity. All the investigated stands, except one, were initially defined as even-aged stands. However, due to a high variability in the individual ages of trees in most of the stands, their structure was defined as covert uneven-aged. All the stands but one, which is at the phase of stand development and has a diameter structure similar to selection structure, are in the optimum phase. It is reflected in accumulated volume, slowed dynamics and consequently lower current increment and increment intensity. Although particular site conditions (high mountainous and sub-alpine vegetation belt) more or less differ from the optimum state, the achieved volume indicates high productivity of the investigated beech forests. Finally, the knowledge of structural and production characteristics of old-growth beech forests is an important starting point for defining the goals of forest management on a regular basis, as well as for the selection of the best measures for the achievement of these goals.

AB  - Predmet ovih istraživanja bile su mešovite šume smrče i jele na prostoru NP Kopaonik, koje pripadaju zajednici smrče i jele - Abieti-Piceetum abietis Mišić et Popović, 1978. Osnov za proučavanje strukturne izgrađenosti i proizvodnog potencijala ovih šuma predstavljaju podaci sa 12 stacionarnih oglednih površina, prosečne veličine 0,18 ha. U odnosu na cenoekološku pripadnost sva ogledna polja pripadaju grupi ekoloških jedinica - šume smrče i jele (Abieti-Piceetum abietis, Mišić et Popović, 1978) na kiselim smeđim i smeđim podzolastim zemljištima, odnosno diferenciraju se u 5 ekoloških jedinica: Abieti-Piceetum abietis oxalidetosum na smeđem podzolastom zemljištu, Abieti-Piceetum abietis oxalidetosum na kiselom smeđem zemljištu, Abieti-Piceetum abietis vaccinietosum na smeđem podzolastom zemljištu, Abieti-Piceetum abietis typicum na smeđem podzolastom zemljištu i Abieti -Piceetum abietis drymetosum na smeđem podzolastom zemljištu. U strukturnom smislu, ove šume karakteriše izražena raznolikost strukturnih oblika, od strukture bliske jednodobnim sastojinama, do tipičnih višespratnih, raznodobnih sastojina. Oblik sumarnih linija raspodela stabala u većini slučajeva uslovljava smrča kao dominantna vrsta. Pri tom, dominiraju tanka i stabla srednje debljine, sa minimalnim prisustvom stabala jakih dimenzija. Prosečna zapremina ovih šuma iznosi 777 m3·ha-1, sa razmerom smese 0,7:0,3 u korist smrče. Prosečna vrednost tekućeg zapreminskog prirasta iznosi 14 m3·ha-1, sa ućešćem smrče 68% i jele 32%. Procenat prirasta se kreće od 1,6% do 2,5% i u svim oglednim poljima nešto je veći kod jele. Stanišni potencijal, sastojinske karakteristike i međusobni odnosni vrsta drveća unutar njih, rezultirali su strukturnom složenošću, visokom proizvodnošću i ekološkom stabilnošću ovih šuma, tako da u budućem gazdovanju treba izbegavati radikalnije mere i zahvate koji bi narušili uspostavljene odnose i dinamičke procese.
AB  - The subject of this research are mixed forests of spruce and fir in the area of NP Kopaonik, which belong to the community of spruce and fir - Abieti-Piceetum abietis Mišić et Popović, 1978. The basis for the study of the structural development and production potential of these forests are data from 12 sample plots, with the average size of 0.18 ha. In terms of coenoecological affiliation all the sample plots belong to the group of ecological units - forests of spruce and fir (Abieti-Piceetum abietis, Mišić et Popović, 1978) on acid brown and brown podzolic soils, which are differentiated into 5 ecological units: Abieti-Piceetum abietis oxalidetosum on brown podzolic soil, Abieti-Piceetum abietis oxalidetosum on acid brown soil, Abieti-Piceetum abietis vaccinietosum on brown podzolic soil, Abieti-Piceetum abietis typicum on brown podzolic soil and Abieti-Piceetum abietis Dr.ymetosum on brown pozolic soil. In structural terms, these forests are characterized by very diverse structural forms, ranging from the structure of even-aged stands to typical multi-storey, unevenaged-aged stands. The form of cumulative curves of tree distribution is in most cases determined by spruce as the dominant species. At the same time, thin and medium-thick trees dominate, while the presence of stems with large dimensions is minimal. The average volume of these forestse is 777 m3·ha-1, with a mixture ratio of 0.7: 0.3 in favor of spruce. The average value of the current volume increment is 14 m3·ha-1, with a 68% share of spruce and 32% of fir. The percentage of increment ranges from 1.6% to 2.5% in all sample plots and is somewhat higher for fir. The site potential, stand characteristics and relations among the tree species have resulted in structural complexity, high productivity and ecological stability of these forests. Therefore, future forest management should avoid radical measures and procedures that would violate the established relationships and dynamic processes.

AB  - Podaci periodičnih potpunih premera stalnih oglednih površina i odeljenja u kojima se one nalaze, u periodu 1955/60-2005/2010, predstaljali su osnov za ova istraživanja. Dva seta podataka iz vremenskog opsega od 50 godina omogućila su komparativnu analizu niza strukturnih i numeričkih elemenata redovno gazdovanih prebirnih šuma jele, smrče i bukve sa šumama koje su se manje-više spontano razvijale na oglednim površinama. Broj stabala u tanjim kategorijama se smanjuje, ali je u odeljenjima u kojima se redovno gazduje on delimično kompenzovan podmlađivanjem i urastanjem, koje iznosi 7,9 stabala godišnje, sa dominacijom jele. U šumama spontanog razvoja urastanje ili izostaje ili je minimalno i iznosi 2,7 stabala godišnje. S aspekta očuvanja prirodne kompozicije ovih šuma, a time i njihove biološke stabilnosti, zabrinjavajući je značajan pad broja bukovih stabala, pre svega u najtanjim debljinskim kategorijama. Nagomilavanje stabala jakih dimenzija izraženije je na oglednim poljima u odnosu na odeljenja u kojima se redovno gazduje. Ovakav trend je rezultirao visokim iznosima temeljnice (max. je u 131. odeljenju i na kraju analiziranog perioda iznosi 37,8 m2·ha-1, a na OP-2 55,7 m2·ha- 1) i zapremine (max. od 605,4 m3·ha-1 ostvarene u 66. odeljenju, sa učešćem jele 79%, odnosno 898 m3·ha-1 na OP-2 u kojoj jela učestvuje 71%). Povećanje zapremine u debljinskim kategorijama iznad 50 cm u odeljenjima u proseku iznosi 120%, a sastojinama spontanog razvoja čak 230%. Tekući zapreminski prirast je visok i u odeljenjima na kraju perioda prosečno iznosi 12,9 m3·ha-1, a na oglednim površinama 14,9 m3·ha-1. U obe vrednosti jela učestvuje sa 80%. Međutim, procenat prirasta, kao pouzdaniji izraz vitalnosti i dobrih stanišnih i sastojinskih uslova opada, sa 2,54% na 2,32% u posmatranim odeljenjima i sa 2,31% na 1,91% na oglednim površinama, u uslovima spontanog razvoja. Na osnovu prethodno iznetog, mogu se konstatovati izvesni poremećaji i negativni trendovi, kako u redovno gazdovanim šumama, tako i u sastojinama spontanog razvoja, pri čemu su oni znatno izraženiji u drugom slučaju. Ovo se ogleda u nepovoljnim prostornim odnosima i svetlosnom režimu, posledično u otežanom podmlađivanju, uraštanju (posebno bukve) i usporenoj dinamici ovih šuma i u konačnoj instanci u poremećaju njihove strukturne izgrađenosti i funkcionalne vrednosti. U redovno gazdovanim šumama uzrok leži u krutom shvatanju prečnika sečive zrelosti i slabijeg zahvata sečama u jači deo inventara, koji je usporio dinamiku i otežao podmlađivanje i uraštanje. Jačim zahvatima u ovaj deo inventara ostvario bi se bolji prostorni raspored stabala (horizontalno i vertikalno), bolji svetlosni režim i ubrzao bi se razvoj ovih šuma. U prilog ovome je i činjenica da bez prebirnih seča, prepuštena samoregulacijskim procesima (spontanom razvoju), prebirna šuma postepeno osiromašuje stablima donjeg i srednjeg sprata i pretvara se u jednoslojnu strukturu sa horizontalnim sklopom što se dešava na istraživanim oglednim površinama.
AB  - The data of periodic complete measurements of permanent sample plots and compartments in which they were located in the period 1955/60-2005/2010 served as the basis for this research. Two sets of data from a 50-year time span enabled a comparative analysis of a number of structural and numerical elements of regularly managed selection forests of fir, spruce and beech that more or less spontaneously developed in the sample plots. The number of trees in low-diameter categories decreased in the regularly managed compartments, but it was partly compensated by regeneration and ingrowth, which amounted to 7.9 trees per year. In forests with spontaneous development, the ingrowth is either missing or minimal, and it amounts to 2.7 trees per year. From the aspect of preserving the natural composition of these forests and thus their biological stability, a significant decline in the number of beech trees is worrying, above all in the lowest-diameter categories. The accumulation of large-dimension trees is more pronounced in the sample plots in relation on the compartments with regular management. This trend resulted in high basal area values (max. was observed in compartment 131 and at the end of the analyzed period, it amounted to 37.8 m2·ha-1, and in SP-2 to 55.7 m2·ha-1) and volume (max. 605.4 m3·ha-1 was achieved in compartment 66, with a 79% share of fir, i.e. 898 m3·ha-1 in SP-2 in which the share of fir is 71%). Increase of volume in diameter categories above 50 cm amounts to on average 120% in compartments, and in stands with spontaneous development to as much as 230%. Current volume increment is high and at the end of the period it amounted to on average 12.9 m3·ha-1 in the compartments, and 14.9 m3·ha-1 in the sample plots. In both these values the share of fir is 80%. However, increment percentage, as a more reliable indicator of vitality and good living and stand conditions decreased from 2.54% to 2.32% in the observed compartments and from 2.31% to 1.91% in the sample plots, under the conditions of spontaneous development. On the basis of the above, certain disturbances and negative trends can be identified, both in regularly managed forests and stands with spontaneous development, while they are significantly more pronounced in the latter case. This is reflected in the unfavorable spatial relationships and light regime, and consequently difficult regeneration and ingrowth (especially of beech) as well as the slowing dynamics of these forests, which finally disrupts their structure and functional value. In regularly managed forests, the reason for that is the rigid understanding of the felling ripeness diamater and lower intensity cutting of large-dimension inventory, which slowed down the dynamics and made regeneration and ingrowth difficult. More intensive operations in this part of the inventory would provide a better spatial distribution of trees (horizontal and vertical) and a better light regime, while the development of these forests would be accelerated. This is confirmed by the fact that forests with self-regulation processes (spontaneous development) become gradually depleted in low and medium storey trees and turn into a one-layer structure with a horizontal canopy which was observed in the investigated sample plots.

AB  - Mixed forests of broadleaved and coniferous trees (beech and fir; fir, spruce and beec) account for 2.4% of the forest area in Serbia. They are characterized by high productivity, ecological diversity, increased resistance to various adverse impacts and structural complexity. Multifunctionality of these forests on one hand and small forest areas below the potential of site opportunities in the growing stock of Serbia on the other have initiated this research in mixed forests of beech spruce and fir on Mt.Tara and beech and fir on Mt.Goč. The primary aim of this research was to analyze the structural, dynamic and dimensional changes in the composition and diversity of tree species in the forests of these sites that were established in the last fifty years. Assessment of the causes, extent and quality of the current changes represent a starting point for the defining of the framework for further management treatment of these polydominant communities in the context of close-to-nature and adaptive management. Data from 15 sample plots were used for this research, of which 6 on Mt.Tara with sizes ranging from 1.0 to 1.85 ha and 9 on Mt. Goč with sizes ranging from 0.93- 1.70 hа. Data collection in the sample plots was performed every time in the same way during each forest measurement in the period from 1955 to 2005 on Mt.Tara, and from 1954 to 2011 on Mt.Goč. Data from periodic full (total) measurements were subjected to standard dendrometric and statistical processing. The assessment of status and the analysis of changes that occurred in researched stands during the specified period was performed on the basis of the following elements: the number of trees, volume, and their distribution by diameter degrees and Biolay diameter classes, basal area, height structure, height curves, current volume increment, dimensions of medium-sized trees, stand volume index, Gini coefficient, recruitment rate index and shares of species in the mixture...

AB  - The growth characteristics of silver fir are of high importance for selection forest management, and for the current aims laid out in Serbia's forest management focused on increasing the share of silver firs in Serbia's growing stock. With the objective of increasing the understanding of the growth characteristics of silver fir, the growth of two silver fir trees felled during forest site production research on Mt. Goc, located in Central Serbia, have been analyzed. Both trees showed significant differences in their growth dynamics over long periods as results of micro-site and micro-stand effects (primarily ambient light regime). The common growth characteristic of the two trees, a 450-year-old tree as the main study object (labeled Tree A) and a 270-year-old Tree B is a long stagnation stage. For Tree A the latent phase, with small interruptions, lasted 410 years; one phase lasted 330 years in continuity, which is the longest period of silver fir stagnation recorded in Europe. Tree B showed a long-lasting stagnation stage that lasted 170 years. The long stagnation stage of Tree A, characterized by an average diameter increment of 1.4 mm/year (average growth ring width of 0.7 mm) and an average height increment of 0.08 m/year, shows the extraordinary silver fir capacity for physiological survival in complete shade. This study adds to the existing knowledge of the shade tolerance of the silver fir. Therefore, the silver fir belongs to the group of extremely shade-tolerant tree species. This characteristic makes silver fir an irreplaceable tree species in the selection forest structure. It offers a wide range of silvicultural flexibility in the management of these forests, and is applicable to silver fir selection Serbia's forests.

AB  - The forest cover of Serbia occupies around 29% of its territory, which puts
   it among fairly well wooded countries in Europe. The forests of Serbia are
   characterized by both state and private forests, medium preservation status,
   i.e. 27% of area that is covered by insufficiently stocked stands. Coppice
   forests cover about 50% of the area, and private forests are additionally

   than 200 years (The Plan of Deliblato Sands Afforestation 1806). There are
   two basic assumptions that define forest management planning: sustainability
   and multifunctionality. Today, forest management planning in Serbia is
   regulated by the Law on forests and it has the characteristics of a system.
   The planning also has the characteristics of an integral, integrated and
   adaptive system. The latter is particularly important in terms of pronounced
   climatic changes. For the forests in protected objects of nature, there are

Jedan od metoda koji pripada ovoj oblasti, a primenjuje se i u šumarstvu, jeste matematičko programiranje (posebno linearno programiranje). Linearno programiranje ima dugu tradiciju primene u američkom i evropskom šumarstvu, dok je u šumarstvu Srbije još uvek teorijska, a pogotovo praktična nepoznanica.

Dobijeni rezultati i strana iskustva u ovoj oblasti nedvosmisleno ukazuju na to da se linearno programiranje može uspešno koristiti i za rešavanje i znatno kompleksnijih problema (u odnosu na prezentovan u ovom radu) u našoj šumarskoj praksi (višedimenzionalno planiranje sa nizom ograničenja).
AB  - In situations where it is necessary to consider a variety of options when making decisions in forestry (and in general), with the choice influenced by hardly comparable criteria and a number of conflicting interests, a possible solution is to use multiple criteria methods. One of these methods, which can be applied in forestry, is mathematical programming (in particular, linear programming). Linear programming has a long tradition of being used in the U.S. and European forestry, whereas in the forestry of Serbia it still represents a theoretically and practically unknown tool. Therefore, in this paper we analyze the possibility of applying the methods of linear programming in developing a plan of regeneration cutting in the poplar plantations of FMU 'Topolik' managed by PE 'Vojvodinašume.' Using the aimed function (linear programming) and the corresponding software package the maximum yield that can be achieved by cutting the plantation was obtained. The planned management period was from 2012 to 2021 and its volume was 155 852 m3. The preset condition that the yield in half-periods remains equal was fulfilled (half-period I 77,925 m3, half-period II 77,927 m3). The maximum yield obtained with this methodology was by 4,040 m3 lower than the theoretically possible yield that would be obtained if all stands were cut down at the end of the second half-period, i.e. higher by 8,430 m3 than the yield that would be obtained if cutting of the stands were performed at the start of the management period. The results obtained and foreign experience in this area clearly indicate that linear programming can successfully be used to solve this problem and even more complex problems (than the one presented in this paper) in our local forest practice (multidimensional planning with a series of constraints).

AB  - Valuable broadleaves, including also wych elms, belong to the category of rare tree species in the growing stock of Serbia. The conservation of Serbian forest diversity and the genetic potential of these tree species require a multidisciplinary study. In this respect, we undertook a dendrometric and health analysis of a wych elm tree on Goč, as it is a rarity by its dimensions, not only from the local, but also from the regional aspects. The tree is 266 years old, its diameter at breast height is 2.09 m, height 42.1 m, and volume (d gt 3 cm) 56.35 m3. Current height increment culminated early, at the age of 20-30 years, attaining 0.5 m, and current diameter increment at the age of 40-50 years when its value was 14.4 mm. The above data point to a high productivity of this elm tree and to favourable site and stand conditions of its development. On the other hand, its current diameter increment and height over the last period (1.7 mm, and 0.03 m respectively) indicate that the tree was in the phase of physiological dying. 10 species of fungi were identified on the tree (facultative parasites or saprophytes), the most significant being Armillaria mellea and Aurantioporus fissilis, which caused central heartwood decay. Other fungi developed saprophytically in the dead part of the stem or in dead branches. Eight insect species (secondary and tertiary pests) were identified, including the two most dangerous elm beetles (Scolytus scolytus and S. multistriatus). Together with the species Saperda punctata and Cerambyx scopolii, they accelerated the dying process of twigs and branches, as well as of the whole tree. Ambrosia beetle Xyleborus monographus infested the stem and the large dead branches and caused minor technical damage in wood. The species Dorcus paralelopipedus, Oryctes nasicornis and Valgus hemipterus supported the faster progress of wood-rotting fungi and thus contributed to physiological weakening and shortened the life cycle of the study elm tree.

AB  - A period of stagnation in silver fir development has been recorded in all felled trees in selection forests of Serbia (233 trees on Mt. Goc and 451 trees on Mt. Tara). In the selection forests on Mt. Goc the stagnation stage ranges between 40 and 330 years, but on Mt. Tara, it ranges from 15 to 185 years. It was concluded that the duration was caused not by the ecological and productivity potential (site class) of the soil for fir development, but primarily by the growth space, resulting from the application of single-tree selection or group selection systems. It was also found that the duration of latent state and tree sizes attained over that phase (except for height, and that was to a lesser extent) did not affect the silver fir tree development in the post-stagnation period.

AB  - Mixed forests of broadleaves and conifers, thanks to their high productivity and high biodiversity, are the most valuable part of the growing stock in Serbia. The aim of this research was to analyze the mixed old-growth forests of fir, spruce and beech in the reserve 'Račanska Šljivovica' so as to define the laws which could be applied in the future forest management on Mt. Tara. The research was based on the data of six periodic complete inventories followed by standard dendrometric and statistical processing. Forest structure was similar to the typical selection structure. The recruitment dynamics (except beech) was relatively favourable, with the ratio to dead trees amounting to 1.72. The number of trees and the volume increased constantly, attaining 422.2 trees·ha-1, i.e. 800.3 m3·ha-1, and the volume increment was above 12 m3·ha-1, despite a slight drop. Silver fir was the protagonist of the selection structure and productivity. It is necessary to stimulate the survival and development of beech at the concrete site, to examine the balanced number of trees and volume, and to investigate the relationship between the number of recruited trees and the stand volume.

AB  - The control method, one of the most reliable methods of selection forest management, has been applied in selection forests of western Serbia in a somewhat modified form (God variety) for fifty years. This paper analyzes the effects of the control method, i.e. its Go variety, in the period from 1960/70 - 2000. It is based on the data of five successive complete inventories of the Forest Management Unit (FMU) "Tara", whose high selection forest of spruce, fir and beech (Piceo-Abieti-Fagettum subass. typicum) trees on diluvium, brown and illimerised soil on limestone, and on limestone in formation with hornfels, are the best quality and the most spacious forests in the Management Class MC 491/1. The effects were monitored through the changes in the distribution of the number of trees and volume per diameter classes, separately for fir as the protagonist of the selection structure, and collectively at the level of a compartment, a typical representative of MC 491/1. Also, the analysis included the changes in the number of trees, volume, current volume increment, yield, and number of recruited trees per unit area (1 ha) by tree species in MC 491/1, occupying an area of 2,648.78 ha. The study results show that in the study period the average volume in MC 491/1 increased by 18.8%, the percentage of conifers increased from 66.0% to 78.5%, and the bearer of the changes was fir. The volume of the mean fir tree increased by 35.9% and it attained 1.086 m(3). The volume increment increased by 15.7%. The selection structure of conifers was satisfactory, but there were problems with beech regeneration, in its stable presence and in its achievement of the targeted structure. The number of trees per unit area (1 ha) decreased, which in the long run could have detrimental consequences, but the sustainability in general was satisfactory. The levels of regeneration and recruitment were satisfactory. The health of the trees was improved; the stands were healthy, vital, and biologically and functionally stable. The study results point not only to a series of positive effects of the several-decades' long implementation of the Goc variety of the control method, but also to some problems, the understanding of which will have a corrective role in the future management of selection forests in western Serbia.

The volume of the mean fir tree increased by 35.9% and it attained 1.086 m(3). The volume increment increased by 15.7%. The selection structure of conifers was satisfactory, but there were problems with beech regeneration, in its stable presence and in its achievement of the targeted structure. The number of trees per unit area (1 ha) decreased, which in the long run could have detrimental consequences, but the sustainability in general was satisfactory. The levels of regeneration and recruitment were satisfactory. The health of the trees was improved; the stands were healthy, vital, and biologically and functionally stable. The study results point not only to a series of positive effects of the several-decades' long implementation of the Goc variety of the control method, but also to some problems, the understanding of which will have a corrective role in the future management of selection forests in western Serbia.",

AB  - The laws and dynamics of individual silver fir tree development in selection forests were studied. The specificities of fir development are: stage of stagnation, rather significant correlation between tree development (especially height) in the post-stagnation period and the dimensions reached at the end of the stagnation stage, two culminations in current diameter and height increment, and a great proximity in the culminations times at different sites. The length of silver fir stagnation and its development and increment over the long post-stagnation period (60 to 70 years in concrete conditions) are affected predominantly by the growing space. After this period, site conditions have the prevailing effect on tree development. The high and long-lasting effect of growing space enables forestry experts to influence the selection forest processes by regulating the light regime. They can accelerate or slow down the processes, but the limiting factor must be the conservation of the selection structure.

AB  - Na bazi podataka nacionalne inventure šuma u ovom radu prikazano je i analizirano stanje šumskog fonda Srbije po različitim kvalitativnim i kvantitativnim pokazateljima. U pitanju su sledeći pokazatelji: način korišćenja zemljišta, vlasništvo nad šumom, poreklo, prirodnost, očuvanost, mešovitost i strukturni oblik šuma, zastupljenost pojedinih vrsta drveća, sastojinska pripadnost, distribucija zapremine po debljinskim klasama, kao i količina suvog (mrtvog) drveta i rezerve ugljenika u šumama Srbije. Analiza ovako prezentovanog stanja omogućila je definisanje nekih od strateških problemi koji pojedinačno i u sadejstvu opterećuju naše šumske ekosisteme, a čija će detaljna razrada, mere i sredstva za prevazilaženje puni izraz dobiti u najvišem planskom dokumentu -Nacionalnom šumarskom programu. U vidu posebnog poglavlja i bez analitike prikazani su i osnovni podaci o šumskom fondu autonomne pokrajine Kosovo i Metohije, preuzeti iz izveštaja Norveške šumarske grupe.
AB  - Based on the data of the National Forest Inventory, this paper presents the basic characteristics of forest ecosystems in Serbia by different qualitative and quantitative parameters. The following parameters were dealt with: land use, forest ownership, origin, naturalness, preservation status, mixture and structural form of forests, percentage of tree species, stand category, volume distribution by diameter degrees, as well as the quantity of dead wood and carbon stock in the forests of Ser­bia. The analysis of the presented state enables the definition of some of strategic problems which individually and acting together burden our forest ecosystems, and whose detailed elaboration, measures and methods of enhancement will be fully expressed in the highest planning document - National Forest Programme. A special section, but without being sufficiently analytical, presents the main data on the growing stock of the Autonomous Province Kosovo and Metohija taken from the Report of the Norwegian Forestry Group.
