Abstract The forests of urbanised areas provide multiple ecosystem services and are highly dynamic. Determining the trends in species composition changes can help to predict their future capacity to fulfil ecological and resource-maintaining functions. We examined the direction of forest successions in the Northeast Moscow region under the canopy of different tree species. Field data were obtained from 78 permanent test plots monitored for more than a 15-year period; field studies were complemented by archival data. The cluster analysis made it possible to divide all plots into five groups by current species composition and structure and into eight groups by the importance of broadleaved species in the undergrowth. Gradual evolution (cohort dynamics) was found to be typical for middle-aged secondary forests; patch dynamics was described in mature stands of late succession species after non-critical natural disturbances; drastic changes were observed in spruce (Picea abies (L.) Karst.) stands after pest attacks. Two main trends were revealed in species composition shift: restoration of mixed spruce-broadleaved forests and development of lime-dominated broad-leaved forests, the latter being the prevailing one in the stands of composite forest types. Intensive development of oak-associated species is probably related to the climate conditions in the Moscow megacity. The content of this article may be of interest for researchers studying natural forest dynamics and can be used for prospective planning of target species composition in the forestries of the Moscow region.

Abstract The weather conditions determine the dynamic forest fire risk. In Poland, the dynamic forest fire risk is calculated using a method elaborated at the Forest Research Institute. The forest fire risk degree (4-level scale) is calculated every day at 9:00 am and at 1:00 pm during the fire season (1.03 till 30.09) for 60 prognostic zones selected on the basis of stand and climatic conditions. 97% of all annual forest fires occur during the fire season. Surface fires are a significant part of the fires (90%) and occur in forest stands where pine is the dominant species. The purpose of the research was to prepare a new method of forecasting forest fire risk, which would enable a more precise method of evaluation of the risk of an outbreak of fire in relation to the existing and forecast meteorological conditions in forests. The results obtained during testing of this method indicate a high accuracy in forecasting fire risk and a satisfactory precision of formulae for calculating moisture content of pine litter. The assumptions of the new method included: – possibility of determining the actual risk of fire for the given area, being the average for all measurement points located on the terrain equally those in which the moisture content measurement of litter has not been performed, – possibility of forecasting the risk of forest fire for the afternoon in the morning hours of the given day, – possibility of forecasting fire risk for the following day, – forecasting moisture content of litter for the afternoon and of the given day and for the following day, – drawing up a method enabling limitation of operational costs of fire prevention system.

Abstract The experiment conducted in the Kampinos National Park since 2015 was aimed at assessing the sprouting ability of black cherry (Prunus serotina Ehrh.) in response to different measures of mechanical control and mycobiota colonizing the dying trees. Basal cut-stump, cutting at ca. 1 m above the ground and girdling were performed on 4 terms, two plots and applied to 25 trees, 600 trees in total. Sprouts were removed every 8 weeks since the initial treatment for 4 consecutive growing seasons, except winter-treated trees. At the end of the fourth season of control, 515 out of 600 trees were dead (86%): 81% on Lipków and 90% on Sieraków plot. Among 18 experiment variants with sprouts removal, 17 showed more than 80% of dead trees. The lowest, 76% share, concerned summer cut-stump at the base of the tree. For winter measures, the share of dead trees was lower in all cases and ranged from 28% to 64% proving that sprouts removal contributes to the drop of sprouting strength and quicker dying of the trees. Almost 80% of trees showed sporocarps that represented 51 taxa of macrofungi in total, including 6 Ascomycota and 45 Basidiomycota. The group of six most frequently encountered fungi includes: Hyphoderma setigerum, Bjerkandera adusta, Peniophora cinerea, Armillaria ostoyae, Nectria cinnabarina, Stereum hirsutum. Both plots had similar share of black cherry individuals with sporocarps of macrofungi, that is, 81% and 78% for Sieraków and Lipków respectively. The share of colonized trees and the number of reported macrofungal taxa increased significantly compared to the year following the treatment. In addition, the composition of macrofungi changed with the progressing dying of trees. These results broaden the knowledge about macroscopic fungi colonising and living on black cherry within its secondary range of distribution. Moreover, one macrofungus and two microfungi new for KNP are reported.

Abstract In 2013–2014, a set of 30 pheromone traps baited with synthetic lures attracting I. duplicatus (Duplodor – 15 traps) and I. cembrae (Cembrodor – 15 traps) was installed in 6 altitudinal transects (1000–1400 m a.s.l., every 100 m of elevation) in the eastern, central and western part of the Tatra National Park (TPN) in Poland and operated during the entire growing season. The main aim of the survey was to check if and to what vertical extent these two species of bark beetles, not yet recorded, are presently distributed in TPN. Collected insects, including non-target Scolytinae and Cerambycidae, were determined. Overall 1896 Scolytid bark beetles belonging to 13 species, all occurring in the whole elevation range, were collected. I. duplicatus (28 specimens in total) was collected in the whole elevation profile, similarly as I. cembrae (718 specimens in total). Among Cerambycidae (282 individuals) belonging to 19 species, Rhagium inquisitor and Pidonia lurida, found on all elevations, were the most abundant; 8 species were collected on the highest locality. Pogonocherus decoratus was found for the first time in the Tatra. Results indicate the upward spreading of the studied insects as a possible effect of climate change and the resulting environmental conditions favourable for those organisms.

Abstract The aim of the study was to determine the distribution of prevailing forest types within the catchment areas of the biggest rivers in the north-east of Ukraine. During the allocation of the catchment areas of the studied rivers, the MapInfo Professional 12.5 program and the vector map of Ukraine were used. The research covered the forest area (more than 502,000 ha) of the state forest enterprises managed by the State Forest Resources Agency of Ukraine. The studied area located on the tributaries of the Sula, Psel, Vorskla and Siversky Donets rivers within the Poltava, Kharkiv, Sumy, Chernihiv, Kyiv and Cherkasy administrative regions of Ukraine. The analysis of the forest fund was carried out based on the electronic subcompartment database of the Ukrderzhlisproekt Production Association, using the application software and geoinformation technologies. It was revealed that a large variety of forest types in the tributaries of the Sula, Psel, Vorskla and Siversky Donets rivers as well as the prevalence of fresh fertile maple-lime oak and fresh fairly infertile oak-pine forest types (in 75 tributaries of Psel, Vorskla and Siversky Donets rivers) and fresh fertile maple-lime oak and fresh fertile hornbeam oak forest types (in 20 tributaries of the Sula River) are due to the relief, hydrological and soil-climatic conditions of the studied area, as well as anthropogenic factor. Assuming homogeneous natural conditions, an insignificant number of forest types are formed (up to five). For a large variety of natural conditions, there are at least six forest types that should be taken into account during forest management, along with the characteristics of the catchment areas of tributaries. The analysed data on the total number of forest types in the catchments of rivers would be appropriate to use in the future when creating a single list of forest types for the Left-Bank Forest-Steppe zone of Ukraine. The prevalence of certain forest types within the catchment areas of tributaries of the Sula, Psel, Vorskla and Siversky Donets rivers directly depends on the soil and climatic conditions, geomorphological structure, relief and anthropogenic influence in the forests. The results should be used in forest management activities to preserve and restore the species diversity of forests within the river catchments.
摘要:本研究的目的是确定乌克兰东北部最大河流集水区内主要森林类型的分布。在分配所研究河流集水区时，使用了MapInfo Professional 12.5程序和乌克兰矢量图。这项研究涵盖了乌克兰国家森林资源局管理的国有森林企业的森林面积(超过502000公顷)。研究区域位于乌克兰波尔塔瓦、哈尔科夫、苏梅、切尔尼耶夫、基辅和切尔卡西行政区域内苏拉、普塞尔、沃斯克拉和西沃斯基顿涅茨河的支流上。利用应用软件和地理信息技术，以乌克兰项目生产协会的电子分隔间数据库为基础，对森林基金进行了分析。据透露,各种各样的森林类型的支流苏拉,Psel,沃斯科拉河东岸和Siversky顿涅茨河以及新鲜肥沃maple-lime橡树和新鲜的患病率相当贫瘠oak-pine森林类型(75年Psel支流,沃斯科拉河东岸和Siversky顿涅茨河)和新鲜的肥沃maple-lime橡木和新鲜的鹅耳枥橡树森林类型(20苏拉河的支流)由于救援,水文和soil-climatic条件的研究区域,还有人为因素。假设自然条件均质，形成的森林类型数量很少(最多五种)。对于各种各样的自然条件，在森林管理期间至少应考虑到六种森林类型，以及支流集水区的特点。在今后为乌克兰左岸森林-草原地区编制单一的森林类型清单时，关于河流集水区森林类型总数的分析数据是适当的。苏拉河、普塞尔河、沃斯克拉河和西沃斯基顿涅茨河支流汇水区内某些森林类型的普遍程度直接取决于土壤和气候条件、地貌结构、地形和森林的人为影响。研究结果应用于森林管理活动，以保护和恢复河流集水区内森林的物种多样性。

Abstract Forests in Kampinos National Park contain some of the most valuable tree populations in Poland. Particularly interesting are stands of Scots pine (Pinus sylvestris L.) that are more than 130-years-old. Periodic observations of the health of tree crowns in these stands facilitates a wide range of research investigations. This article evaluates statistical relationships between allometric features of trees and the occurrence and severity of crown defoliation. Observations were made of 5 pine populations in 2017 and 2019, in which detailed data were collected for 250 trees. The percentage loss of the assimilation apparatus and level of stand damage were calculated. The results revealed a significant increase in defoliation between 2017 and 2019. The deterioration of crown condition was particularly evident on the most fertile sites. The degree of crown damage was not correlated with tree height or diameter. The greatest increase in defoliation between 2017 and 2019 was observed for the most severely damaged trees growing on fertile sites. This study contributes analyses aimed at correlating the allometric features of a stand with its health. Such information is valuable as it describes the status of the analysed stands, as well as providing information about how trees have responded to environmental conditions. In this study, crown defoliation coincided with a period of drought in Poland, which appears to have affected pine stands. For these reasons, the results are of both scientific and practical value.

Abstract Deterioration of water conservation, water protection, water-regulating, soil-protective, health and recreational properties of urban forests is an urgent problem in urban areas. Researching the state and growth characteristics of urban forests will help in developing the best forestry management activities of care. The objects of study were the urban forests of Kharkiv region. During the study, methods commonly used in forestry, forest inventory and biometrics were applied. The investigation determined a species range of urban forests and prevailing species in terms of users. The stands’ distribution by species composition, age groups, their average age, site class, stand density and timber volume was determined. The practicability of further research of these objects was proved.

Abstract Whilst, in many countries, the scale of forest loss from business-as-usual development is immense, in Poland, this problem does not exist. However, obtaining additional land areas for afforestation is a main issue in Poland. In Poland, after the World War II, the forest area has been systematically growing. In 1945, the forest area was about 6.5 million ha, and the forest cover was 21%. In 2016, the forest area reached 9.2 million ha, and forest cover amounted to 29.5%. Today, there are 0.24 ha of forests per one inhabitant of Poland. The size of wood resources in stands is also changing. In 1945, forest resources on the trunk amounted to approximately 906 million m3, and in 2016, it reached 2.4 million m3. The problem, however, is the uneven distribution of forests in Poland. Forests in Poland are very strictly protected by law. There are two most important acts, Forest Act of 2001 and Nature Conservation Act of 2004, that regulate principles for the retention, protection and augmentation of forest resources. Over the past decades in Poland, the social demands regarding non-economical functions of forest such as recreational activities, soil and water protection and mitigation of global warming became an important and constantly growing challenge for forest managers. Thus we suggest that, first of all, it is very important to extract the leading function for a given forest area. Interactions between development and conservations policies are very tied and may suggest the need of their integration. In this article, we present the concept of development policy for forest management and forest protection in Poland.

Today, there are 0.24 ha of forests per one inhabitant of Poland. The size of wood resources in stands is also changing. In 1945, forest resources on the trunk amounted to approximately 906 million m3, and in 2016, it reached 2.4 million m3. The problem, however, is the uneven distribution of forests in Poland. Forests in Poland are very strictly protected by law. There are two most important acts, Forest Act of 2001 and Nature Conservation Act of 2004, that regulate principles for the retention, protection and augmentation of forest resources. Over the past decades in Poland, the social demands regarding non-economical functions of forest such as recreational activities, soil and water protection and mitigation of global warming became an important and constantly growing challenge for forest managers. Thus we suggest that, first of all, it is very important to extract the leading function for a given forest area. Interactions between development and conservations policies are very tied and may suggest the need of their integration. In this article, we present the concept of development policy for forest management and forest protection in Poland.","PeriodicalId":35789,"journal":{"name":"Folia Forestalia Polonica, Series A","volume":"4 1","pages":"31 - 38"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82414542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Global climate change has mainly impacted the forest ecosystems in Europe. Today, it is not fully understood how these changes will affect the reproductive process of trees on seed orchards. The main aim of the study is to evaluate the growth, condition and reproductive function of Scots pine clones of Finnish origin after moving them to the southern direction of natural distribution area. Variability and seed productivity of 25-year-old clones of Scots pine of Finnish origin in the clonal seed orchard under climatic conditions of the central part of Ukraine (Vinnitsa region) was investigated. Grafted seedlings of Scots pine of Finnish origin were moved southward at a distance of over 1,500 km. Climatic conditions of Vinnytsia region, where the clones were displaced, differed by an increase in the mean and maximum temperatures by 3.3–3.6ºC, as well as an increase in the mean temperatures during the cold period and a rise in the minimum by 2.1–2.3ºC. The climate in the seed orchard location was characterized by the most significant increase in the mean temperatures in April and May (5.3–5.8ºC), which greatly influenced the intensity of the formation of microstrobili and macrostrobili. The ratio of precipitation to the amount of temperatures decreased more than twice. Analysis of the grafted trees’ vitality of Finnish origin and seed progeny of the local population, estimation of their intensity (height, diameter), state (category of the state) and reproductive processes (intensity of formation of microstrobili and cones) was carried out on the clonal seed orchard. In conditions of climate change, most of the clones of Finnish origin were characterized by a higher intensity of flowering compared to the local population. Some clones of Finnish origin (E80 and E729) dominated the local population by the seed yield. According to a comprehensive analysis of vitality, the intensity of growth and reproductive capacity, the best clones of Finnish origin were E80, E1883 and E2254. Low adaptive ability was noted in the clones E2312, K634 and K801. According to the research results, it was found that changes in climatic conditions did not significantly affect the vitality, development and condition of the clones. There was observed intensification of the formation of microstrobili and cones. Seed viability and quality of Scots pine of Finnish origin obtained on seed orchards located in the southern conditions requires further research.

Abstract In forest production, there is an emerging tendency towards the planting of fast-growing trees as attractive, renewable energy sources. Hence, efforts were made to develop a method of micropropagation by organogenesis of seven clones of black locust (Robinia pseudoacacia L.) that are resistant to propagation by traditional vegetative methods, as well as one plus tree (no. 9755) at the age of 60, to see if the age of the mother plant is a limitation in the micropropagation of black locust trees. Overall results suggest that Murashige and Skoog medium supplemented with 30 g l−1 sucrose, 0.6 mg l−1 6-benzylaminopurine (BAP) and 0.1 mg l−1 naphthalene acetic acid (NAA) is better for the propagation of each genotype of R. pseudoacacia than Woody Plant Medium with the same growth regulators, and the age of the donor plant does not affect the organogenic potential. Recalcitrance to adventitious rooting from adventitious shoot formation is a major limitation for the clonal micropropagation of forest trees. Our results showed that although the roots were also formed spontaneously in the growth medium without growth hormones for the tested black locust clones, the application of auxin increased the total root length compared to that in the medium with active carbon and control. A significant effect of the additives of hormone and sucrose on the total root length was found. Increasing the sucrose concentration stimulated the induction of roots in each of the tested concentrations (5, 10, 15 or 20 g l−1). Additionally, the change in sugar dose in the rooting medium caused significant differences in total root length.
在森林生产中，种植速生树木作为有吸引力的可再生能源是一种新兴趋势。为此，本文研究了7个对传统无性繁殖有抗性的刺槐(Robinia pseudoacacia L.)无性系和1 +树(1 + tree)无性系的器官发生繁殖方法。9755)，以观察母株的年龄是否对刺槐树的微繁有限制。结果表明，在Murashige和Skoog培养基中添加30 g l−1蔗糖、0.6 mg l−1 6-苄基氨基嘌呤(BAP)和0.1 mg l−1萘乙酸(NAA)对刺槐各基因型的繁殖效果均优于添加相同生长调节剂的木本植物培养基，且供体植株的年龄不影响其有机潜能。对不定根形成不定根的抗拒是制约林木无性系微繁殖的主要因素。结果表明，虽然在不添加生长激素的培养基中，刺槐无性系的根也能自发形成，但与添加活性碳和对照培养基相比，添加生长素使刺槐无性系的根总长度增加。激素和蔗糖的添加对总根长有显著影响。增加蔗糖浓度在每个测试浓度(5、10、15或20 g l−1)中都刺激了根的诱导。另外，生根培养基中糖浓度的变化对总根长也有显著影响。
