Abstract

The article presents the results of scientific research on the development of a system of growth and productivity models for stands of the main forest-forming tree species of Ukraine on basis of the yield tables proposed by Ukrainian scientists. The fundamental prerequisites for creating the system and ways for its further development and improvement are grounded. The methodological ground is formed by the developments of Ecosystems Services and Management Program of the International Institute for Applied Systems Analysis in modeling growth, productivity and bioproductivity of forests. Von Bertalanffy’s growth function serves as a mathematical basis for the research, by means of which fitting of series of dynamics of stand mean height, diameter, basal area sum, growing stock and total productivity was secured for the studied stands. Perspectives for further application of the results and developments described in the article lie in the sphere of integration of the updated description of dynamics Ukrainian forests to regional and global models of dynamics of forest ecosystems to account for the impact of global climate change and forecast their state middle- and long-term prospect.

Abstract

The oak-spruce stands in Podillya region in fresh hornbeam oak forest type were studied. Comparison of productivity of oak stands with and without spruce introduction in the initial stand composition was performed. The dynamics of productivity change and distribution of oak and spruce trees by diameter were analyzed. It was found that there is an opportunity to get 70–130 m3 of wood additionally in oak and spruce stands up to 40–50 years in Podillya. The optimal is two-stage stand cutting by felling spruce at age of 40 and 60 years. The intensity of the first stage should be 30–50 % with further cutting the reserved part. The most appropriate method is to conduct the first cutting of spruce trees of Kraft classes 1 and 2 to reduce the competition impact on oak. Later spruce felling leads to oak inhibition and reducing its productivity.

Abstract

The article considers the structure and the features of formation of birch stands in the Eastern Polissya of Ukraine. The analysis of health condition as well as the comparing of the actual productivity with tabular data for birch normal stands was carried out. It is shown that the age structure of birch stands is not optimal due to an area exceeding of mature and overmature birch stands and deficiency of young stands. In the initial stages of birch forests formation, the birch dominates along with other small-leaved species. With aging, the participation of birch in the composition of the secondary stand increases. The health condition of birch stands is deteriorated with age increasing and decreasing the birch participation in the stand composition. The actual productivity of birch forests is about 80 % of stand volume with the density of birch stocking 1.0. The technical quality of the wood of mature birch stands refers to the 2nd and 3rd merchantability classes.

Abstract

The European spruce (Picea abies L.) stands were studied in the territory of Poloninskyy Ridge in Ukrainian Carpathians in moist fairly fertile (C3) and moist fertile (D3) prevailing forest site types (FST). The peculiarities of wood density dynamics for the stem wood, bark covered wood and a bark were analyzed in oven-dry state and under full humidification. The basic wood density was analized, too. An average basic wood density in FST C3 is 392 ± 9 kg•(m3)-1, and in FST D3 it is 345 ± 8 kg•(m3)-1 The maximum difference in average values of basic stem density in different types of site conditions is peculiar to the bark – 103 kg•(m3)-1 (25.4 % of the value in the FST C3) as compared to the rest of the fractions, where the difference is less significant: the value of the average basic stem wood density differs by 45 kg•(m3)-1 (12.0 % of the value in the FST C3) and bark covered stem wood by 64 kg•(m3)-1 (16.4 % of the value in FST C3). An age dynamics simulation was done for the basic stem wood density and its dependence on the diameter and height of the stem. It was found that the reduction of the values at a young age and the gradual increase to the age of maturity is peculiar to the dynamics of average basic stem wood density of European spruce in FST C3 and D3. Average values of the characteristic are higher in the FST C3 compared to FST D3.

Abstract

The area distribution for oak stands of Polissia zone of Ukraine by origin, age classes, type of site conditions, relative stand density, site index and oak units in stand composition was shown in the context of administrative regions using data from subcompartment database of Production Association “Ukrderzhlisproekt”. Weighted averages of inventory indices for oak stands of Polissia were calculated for administrative areas. The predomination of middle-aged high-forest (VII–VIII age classes) and ripe short-stemmed, medium stocked (0,64–0,71) and highly productive (I–II site class) oak stands was found. A comparative study of the calculated average inventory indices were made in the context of administrative regions, origin and types of growing conditions. Forestry and environmental potential of the oak stands of Polissia as well as their natural and artificial regeneration capabilities were estimated in different types of forest site under climate change.

Abstract

Indicators of windfalls in the beech and spruce zones of the Carpathians are considered. The estimation of their distribution on the altitude of hornbeam-beech stands is done. Wind resistance ranking of the forest species for the beech forest zone is adduced. The features of the windfalls situations occurrence in the Latoritsa basin depending on exposure and steepness of slopes and on the altitude are characterized. A significant wind resistance weakening of beech forests during storm winds is reported. Quantitative changes of forestry and taxation indicators of the beech forest stands under the influence of partial windfalls are presented. Measures on the beech forests stability strengthen by natural forest stands restoring and by implementation of the against windfall protection system. Main forestry parameters of the windfall forest areas after the storm May 15, 2014 are given in this respect. It was found that forest stability does not significantly depend on its species composition in extreme weather situations with storm winds.

Abstract

The article presents an analysis of taxation indicators for dynamics of species and climatypes of the genus Larix in fresh fertile site type of the Left-bank Forest-Steppe of Ukraine over a 60-year period. New patterns of age dynamics are revealed. It was shown that larch provenances, which were characterized by high growth intensity at a young age, retained leadership up to 60 years. This indicates the possibility of early diagnosis of growth and development of larch, in the period from 10 to 20 years. The previous high taxation indices of the best provenances of European larch from Transcarpathia, Chekanovsky larch from the Irkutsk region, and the Dahurica larch from the Khabarovsk Territory, as well as the Sukachov larch from the Perm region, have been confirmed, which allows them to be recommended for the forest plantation creation in the Left-bank Forest-Steppe of Ukraine.

Abstract

Climate-regulating and carbon sequestration functions of stands of the Velikoanadolsky forest area were analyzed and quantified. A positive impact of forest stands of the forest area on micro-climate, in particular on the air temperature and humidity of the climate, was defined. Under the influence of forest stands of the forest area the sum of positive monthly temperatures is reduced by 2–5 %, and the average temperature during the growing season by 1–6 % as compared to the open area. The difference between the humidity of the climate by Vorobiev in the forest and in an open area in the period of 2002–2016 was increased from 0.4 to 0.7. The amount of carbon sequestration of artificial oak stands of the forest area was determined. At present, carbon sequestration by artificial oak stands is 260 thousand tons.

Abstract

In the article the results of the level of genetic variation assessment, subdivision and differentiation of forest stands of European aspen (Populus tremula L.), silver birch (Betula pendula Roth.) and English oak (Quercus robur L.) on the territory of Belarus, its eastern border regions and the Republic of Tatarstan are presented. The investigation was conducted by using isozyme, RAPD- and SSR-markers. It was shown that the analyzed tree species are characterized by wide range of indicators of genetic diversity. According to isozyme analysis at the species level the share of polymorphic loci (P99) ranges from 0.385 to 0.769, the average number of alleles (A) ranges from 1.923 to 3.231, observed heterozygosity (Ho) ranges from 0.114 to 0.227, expected heterozygosity (He) ranges from 0.115 to 0.237. The lowest values of P99 and A are revealed in forest stands of European aspen. The lowest values of Ho and He are revealed for silver birch stands. English oak stands are characterized by the highest level of genetic variation on all indicators. Based on the DNA analysis the lowest values of the genetic diversity are revealed in aspen stands. Analyzed tree species are characterized by low levels of subdivision and differentiation.

Abstract

The article deals with the results of study of amino-acid humate fertilizer “Rokohumin” using for growing containerized planting stock of oak in individual containers made of an agrotextile. It was established that the effectiveness of the fertilizer depends on the input method and concentration of working solutions. The maximum effect on strengthening of growth in height and diameter of root collar and increase air-dry weight of aboveground and underground parts of seedlings was obtained in a variant with fertilizer solution concentration of 20 ml•l-1. The average height of seedlings in this version is bigger by 81 %, diameter by 42 %, mass of aboveground and underground parts by 68 % and 27 % respectively. Leaf feeding with fertilizer solution 10 ml•l-1 contributed to more active growth in height by 45 % and increase the weight of aboveground parts by 25 %. Leaf feeding did not affect on root weight. The use of "Rokohumin" gives an opportunity to obtain planting material with given sizes, including large-sized, for use not only in silvicultural work, but in horticulture.

Abstract

Importance of geographical analysis of forest flora as a component of modern system approach for investigations of phytodiversity within forest areas and methodical support of forest biodiversity monitoring system is substantiated. The diversity of geographical elements (geoelements) of flora (groups of species similar on geographical distribution and origin) represents both the historical development features of flora in the certain forestland, district or region and adaptive possibilities of its species. Investigation relevance is caused by the international obligations of Ukraine in relation to biodiversity conservation, establishment of forest monitoring system and sustainable forest management. The object of researches is forest flora in woodland “Large Forest” located within southern part of Left-bank forest-steppe zone of Ukraine. The inventory of vegetation species composition was carried out in 24 subcompartments with oak stands of natural (vegetative and seed) origin of middle-aged and senior-aged classes in dry, fresh and moist maple-linden fertile oak forest type (0,980 km2) and 1 subcompartment (area of 0,039 km2) with middle-aged alder stands of vegetative origin in wet black alder fertile site type. The scheme of H. Meusel with co-authors was used as the basis for classification of the types of plant species areals (regional-geographical and latitudinal-zonal) in the forestland. The absolute and relative values of richness with the species of zonal and regional flora geoelements were investigated. Species distribution within Ukraine was pointed according to the natural zones and administrative-territorial units. Simultaneous comparison of geographical structure of flora for two forest formations, Querceta roboris and Alneta glutinosae (according to the Ukrainian dominant classification), and two vegetation classes, Querco-Fagetea and Alneta glutinosae (according to the Braun-Blanquet syntaxonomic classification), was executed in relation to general geographical spectrum of forest flora within the investigated woodland area. The analysis of areals provides as well the identification of relict and endemic species, species on the areal boundaries, species widespread and narrow-spread within Europe, its adjoining territories and Ukraine, and adventitious species. The zonal analysis of areas of species represented within the forestland testifies that leading positions are occupied by temperate species of broadleaved forests (50,6%); boreal species of coniferous forests and also pratal and paludous coenosises rank next (45,4%). There is a some greater percent of temperate elements in oak forest formation and boreal elements and absence of temperate elements in alder forest formation. Some species from herbaceous layer are arctic-meridional, plural-zonal and adventitious (1, 2 and 1, respectively). An adventitious element presents only 1,1% of forest flora, however the establishment of monitoring on potentially possible adventization of forest floristic composition is required. The regionally-geographical spectrum of flora in the forestland is presented mainly by the group of species with the European areal (39,4%) which is characteristic for florae of modern European Forest-steppe and Left-bank Forest-steppe of Ukraine and is basis for flora of broad-leaved nemoral formations. The majority of species with European and European-Western-Siberian areals and all Eastern European group are widespread in the ecosystems of oak forests. The European-Siberian species are recorded only in alder forests, that indicates the connection of Alneta glutinosae formation geoelements with Northern (Polissya) florae. The European species are prevailed in the leading zonal temperate element including 6 species (Corydalis solida (L.) Clairv., Corydalis marschalliana Pers., Scilla sibirica L., Galium odoratum (L.) Scop., Asarum europaeum L., Aconitum lasiostomum Reichenb.) which are the relics of Atlantic period. Boreal element is represented mainly by the large areal species of the European-Asian origin, among which 4 species (Angelica sylvestris L., Arabis pendula L., Actaea spicata L., Equisetum sylvaticum L.) belong to the relics of Wurm period. Six species of herbaceous plants (Aconitum lasiostomum Reichenb., Arabis pendula L., Veronica capsellicarpa Dubovik, Corydalis marschalliana Pers., Scilla sibirica L., Tulipa quercetorum Klok. et Zoz) have areals within forest-steppe and part of the steppe zones of Ukraine. One species (Tulipa quercetorum Klok. et Zoz) is endemic of Southern European part of Ukraine with national and international conservation statuses. Research of regionally-geographical and latitudinal-zonal structure of forest flora is the important component of system approach for investigations of phytodiversity within forest areas and methodical support of forest biodiversity monitoring system. The analysis of areals of relict and endemic species, species on the areal boundaries, species wide-spread and narrow-spread within Europe, its adjoining territories and Ukraine, and also adventitious species assists the identification of features of forest flora historical development and forest biodiversity conservation.

Abstract

Ukrainian Research Institute of Forestry and Forest Melioration named after G. M. Vysotsky The results of research of heavy metals accumulation in various components of ecosystems in pine forests of the industrial zone of Zmiev Thermal Power Plant are presented. The studies were based on methods of comparative ecology. The sample plots were located on the ecological profile on 4 to 28 km from the Zmіev Thermal Power Plant. The concentration index (Іc) was defined as the ratio of the element content in the investigated object to its content in the control. It was shown that the release of emissions into the atmosphere is the primary cause of pollution and negative changes not only in an aerotope (air, precipitation), but also in a trophotope (litter and soil). By the level of concentration index, soils are less contaminated by heavy metals than the litter. In the needles, the mean value of concentration indices is determined. In the industrial zone, the ash and heavy metals content in the needles increases with the aging. The main source of litter contamination is the sedimentation of ash emissions on the earth's surface. The obtained data on the mortmass reserves of the litter allowed determining the value of the total pollution of this ecosystem component. The proportion of heavy metals increases downward along the litter profile. The extremely big difference is between the litter and humus layers of the litter. Heavy metals storage in the H layer is tens or even hundreds of times larger than in the L layer.
