Abstract Deadwood is an important component of forest ecosystems, and difference in the deadwood carbon stock depends on many variables including forest management. The aim of our study was to determine the patterns of formation of deadwood stocks in oak (Quercus robur L.) forests in the Left Bank Forest-steppe of Ukraine. As an outcome of the research, the data on deadwood parameters were obtained. The growth characteristics and coarse woody debris (CWD) characteristics were measured on intensive monitoring and inventory plots. Assessment of morphometric parameters of the CWD in oak stands was carried out by measuring diameters at top and bottom cut and length; to determine the carbon content, deadwood density was used. The distribution of deadwood by tree species, sizes and stages of decomposition was defined. The stock of dead trees (snags) in oak forest is 15.2 m3/ha and that of logs is 21.5 m3/ha. The carbon accumulation in oak forest stands in the Left Bank Forest-steppe of Ukraine was 3.4 and 4.5 t C/ha in dead trees and logs, respectively. The dynamics of deadwood stocks according to the results of repeated observations was given.

The paper presents the data on the number of advance growth of economically valuable species under the canopy of natural oak stands of different age (60–140 years). The study was carried out in the conditions of fresh and moist maple-lime fairly fertile oak forest type in the forest-steppe part of the Sumy region. The species composition, age, quality and occurrence were determined in this study. The evaluation was given for the regeneration success. After a seed year, a mass oak sprouting of economically valuable species, particularly of oak, was observed in maple-lime fairly fertile oak forests of the region. The sprouts were evenly spaced in the area. In the conditions of fresh maple-lime oak forest type, the total of regeneration varied from 11.1 to 17.4 thousand stems per ha, including oak from 2.3 to 10.3 thousand stems per ha. In the conditions of moist maple-lime oak forest type, the total regeneration was slightly smaller (from 9.1 to 13.7 thousand stems per ha) compared with fresh oak forest type, including oak 1.9–4.6 thousand stems per ha. The advance regeneration was characterized as «insufficient» and «satisfactory». To promote natural seed regeneration of oak forests, activities are proposed.

Abstract Dead wood plays an important role for the biodiversity of forest ecosystems and influences their proper development. This study assessed the amount of coarse woody debris in municipal forests in Warsaw (central Poland). Based on the forest site type, dominant tree species and age class, we stratified all complexes of the Warsaw urban forests in order to allocate 55 sample plots. For these plots, we determined the volume of dead wood including standing dead trees, coarse woody debris and broken branches as well as uprooted trees. We calculated the amount of dead wood in the distinguished site-species-age layers and for individual complexes. The volume of dead matter in municipal forests in Warsaw amounted to 38,761 m3, i.e. 13.7 m3/ha. The obtained results correspond to the current regulations concerning the amount of dead organic matter to be left in forests. Only in the Las Bielański complex (northern Warsaw) volume of dead wood is comparable to the level observed in Polish national parks or nature reserves, which is still far lower than the values found for natural forests. In general, municipal forests in Warsaw stand out positively in terms of dead wood quantity and a high degree of variation in the forms and dimensions of dead wood.

It was found that during the period of observation at hospitals forestry radiation monitoring in fresh upland oak forests and wet Pinetum compositum main drive radiocaesium is oak, which is connected, apparently, with its biological and ecological features. It is also clear that, along with the biological specificity of a particular tree species, an important role in the accumulation of woody plants play a cesium type of forest growth conditions (trophicity, humidity). In woody plants most contaminated surface tissues that make up the crust. Further, the degree of contamination, followed by leaves (needles), small branches, wood with bark and wood peeled, where radiocaesium virtually identified.

The article reports new results on the reconstruction of the noncommercial weakened coppice oak stands in the Left-bank Forest-Steppe zone, Ukraine. For the first time, a technology of reconstruction of coppice stands into the mixed seed natural or planted ones is proposed through regeneration felling with the elements of even gradual, group successive and strip gradual felling with a continuous cutting of 25 m width strips. The use of the technologies that combine regeneration felling, selective sanitary felling and thinning in conjunction with silvicultural activities will allow to form mixed seed natural or planted stands of different ages from noncommercial weakened coppice oak forests and significantly increase their productivity and sustainability.

to date, the main parameters for assessing the state of the forest are the average age, height, diameter, and completeness of the main forest-forming rocks, expressed in meters, fractions of a meter, or cubic meters. At the same time, on the same test areas, other measurement measures are used for soil research: milligrams, grams, percentages, moles, etc. Naturally, it is impossible to combine these indicators when characterizing the forest environment. To do this, first of all, you should choose a single system of measures, parameters and indicators that combine the biogenic and lithogenic parts of the landscape. Knowing that their interaction is based on energy and mass exchange, we suggest using measures common to both subsystems. The initial indicators for quantifying the oxygen-producing and carbon-depositing functions, as well as the energy accumulated in the primary products of forest ecosystems, are the elements of biological productivity expressed in weight units. The object of research – Voronezh upland oak forest, with a total area of more than 7 thousand hectares, is the Central organizing element of the entire urban ecosystem of Voronezh. The tree stand is represented by coniferous crops along the left Bank of the floodplain terraces, as well as broad-leaved forest plantations spread on the riverine slopes of the watershed.

Abstract Changes in the areas and stock volumes of oak stands were analyzed within the six administrative regions in the plain area of Ukraine, based on forest management data (subcompartment database) as of 2001 and 2016. The studied regions geographically related to the Left-bank Forest-Steppe zone of Ukraine (Kyiv, Poltava, Sumy, Kharkiv, Cherkasy and Chernihiv Regions). The analyzed area was over 284,000 hectares. The paper outlines the present state of the oak stands, concerning their origin (vegetative, natural seed and planted seed stands). Forestry-taxation indices of the stands were determined by grouping the plots according to age and further clustering in four age groups. The natural regeneration under a canopy in oak stands was accounted and estimated using circular 10 m2 (R = 178 cm) accounting plots. The oak forests were found to be dominated by stands of vegetative (coppice) origin (57%). Planted seed-origin oak stands covered 101,000 ha or 36% of the total area (284,000 ha). Stands of natural seed origin amounted to 7%. From 2001 to 2016, the total area of oak forests in the study region decreased by nearly 7,000 hectares. The analysis of literature sources allowed identifying numerous factors, which have the greatest influence on the emergence, liveability, and growth of natural regeneration of pedunculated oak. Only 20% of the investigated oak stands were found to have a sufficient amount of oak regeneration. For the implementation of sustainable forest management, activities should be aimed at optimizing the age structure of oak forests and growing natural forests from seeds.

Abstract Within Voronezh city there is a green zone, the core of which are forest clusters of natural origin. The study sites are located in the recreational area of an upland oak forest. In such conditions, the forest litter and the upper soil horizon first experience transformation. All results were processed by StatSoft STATISTICA for Windows 10.0. In this study we found that low-thickness forest litter was formed in the Voronezh oak forest, in which the average content of macronutrients was (%): C – 2.91, N – 1.11, K – 0.32, and P – 0.18. These elements can be arranged in a variation series C > N > K > P. It is established that the edaphotope of oak forests of the forest-steppe has a favorable regime for the destruction of organic substances and the accumulation of decomposition products. The content of macronutrients in the forest litter and the upper part of the humus horizon is arranged in the same row N > K > P, which indicates their genetic relationship. The obtained data on the ecological state of the forest litter and the humus horizon of the gray forest soils of the oak forests of the megalopolis are important for understanding the biological cycle under conditions of technogenic and recreational loads.
