Abstract In this study we analyzed the effect of selected biometeorological variables on the onset of phenophases in three beech stands in different climatic areas (warm, moderately warm and cold). We have focused on two phenophases - leaf unfolding and leaf colouring. Timing of both phenophases was identified visually and using series of MODIS satellite images. The data were collected during a 13-year period (2000-2012). For the spring period, we found a significant dependence between temperature and precipitation-based biometeorological variables and leaf unfolding in both datasets - those based on visual and remote sensing-based observations. The average air temperature in the period from February-April was the most significant factor which initiated the onset of beginning of leaf unfolding in all three investigated stands. The evapotranspiration-based biometeorological variables (climatic water balance, actual evapotranspiration, dryness index) had no effect on the onset of the beginning of leaf unfolding observed using both methods. The high precipitation totals in April caused the later onset of leaf unfolding in all stands. The relationship between the first autumn phenophase - leaf colouring and biometeorological variables was found significant in beech stand in the warm climatic area only.

摘要本研究分析了不同气候区(暖、中暖和冷)3个山毛榉林分物候期发生的生物气象变量。我们重点研究了两个物候期——叶片展开和叶片着色。这两个物候期的时间是目测和使用一系列MODIS卫星图像确定的。数据收集于13年期间(2000-2012年)。在春季，我们发现基于温度和降水的生物气象变量与基于视觉和遥感观测的两个数据集的叶片展开之间存在显著的依赖关系。2 - 4月的平均气温是导致3个调查林分开始展开的最重要因素。以蒸散发为基础的生物气象变量(气候水分平衡、实际蒸散发、干燥指数)对两种方法观测到的叶片展开开始时间均无影响。4月降水总量大，导致各林分叶片展开时间晚。暖气区山毛榉林分初秋物候-叶色与生物气象变量的关系显著。摘要:V práci sme analyzovali vplyv biometeorologických premenných na nástup fenologických fáz V troch bukových porastoch nachádzajúcich sa V rozdielnych klimatických oblastiach (teplej, mierne teplej a studenej)。Sledovanými fenofázami boli za iatok zalistenia a za iatok žltnutia listov。其中nástup bol sledovaný vizuálne a s použitím satelitných údajov MODIS。Pozorovania prebiehali po as 13- ro n - odobia(2000-2012)。V jarnom období sme zistili významný vplyv biometeorologických premenných založených na teplote a zrážkach na zaiata zistenia bukových波拉斯托夫zisten - vizuálnym aj satelitným sledovaním。Najvýznamnejšou z týchto premenných bola priemern teplota vzduchu od februára do apríla, ktor vyvolávala skorší nástup za iatku zalistenia na všetkých troch bukových stanovištiach。Vyššie úhrny zrážok v mesiaci apríl spôsobovali na sledovaných stanovištiach neskorší nástup tejto fenofázy。Naopak, premenn založené na evapotranspirácií (klimatick vodn bilancia, aktuálna evapotranspirácia，索引等)nemali žiaden vplyv na za iatok zalistenia zistený oboma metódami。Vzťah medzi provou jesenou fenofázou - za iatkom žltnutia listov a biometeorologickými premennými bol významný iba na bukovom stanovišti nachádzajúcom sa v teplej klimatickej oblasti。

Abstract The paper presents information on the projected drought exposure of Central Europe, describes the anticipated dynamics of the regional forests, and identifies measures facilitating the adaptation of forests to climate change-induced drought risk. On the basis of an ensemble of climate change scenarios we expect substantial drying in southern Slovakia and Hungary, while such trends were found to be less pronounced for the Czech Republic and Austria. In response to these climate trajectories, a change in species composition towards a higher share of drought tolerant species as well as the use of drought resistant provenances are identified as paramount actions in forest adaptation in the region. Adaptation to aggravating climate change may need to use artificial regeneration to enrich local gene pools and increase the drought tolerance of stands. Increasing risks from pests, pathogens and other disturbances are expected as a result of more frequent and severe droughts, underlining the need to put a stronger focus on risk management principles rather than on indicators of productivity in silviculture and forest planning. A consolidation of disturbance monitoring systems and a broader use of pest dynamics and hazard rating models are paramount tools to facilitate this adaptation process in forest management. The effectiveness of all the suggested measures needs to be controlled by efficient forest monitoring systems, the consolidation of which seems to be a timely task. Systematic and long-term implementation of the presented measures should increase forest stability and resilience, and further secure the sustainable provision of ecosystem services under climate change.

摘要:本文介绍了中欧地区干旱暴露的预测信息，描述了该地区森林的预期动态，并确定了促进森林适应气候变化引起的干旱风险的措施。根据一系列气候变化情景，我们预计斯洛伐克南部和匈牙利将出现大量干旱，而捷克共和国和奥地利的这种趋势则不那么明显。为了响应这些气候轨迹，物种组成的变化以及抗旱种源的使用被认为是该地区森林适应的最重要行动。为了适应日益加剧的气候变化，可能需要利用人工更新来丰富当地基因库，提高林分的耐旱性。由于更频繁和更严重的干旱，虫害、病原体和其他干扰的风险预计会增加，这突出表明需要更加注重风险管理原则，而不是造林和森林规划方面的生产力指标。巩固干扰监测系统和更广泛地使用有害生物动力学和危害等级模型是促进森林管理中这种适应进程的重要工具。所有建议的措施的有效性需要由有效的森林监测系统加以控制，巩固这一系统似乎是一项及时的任务。系统和长期地实施所提出的措施应能提高森林的稳定性和复原力，并进一步确保在气候变化下可持续地提供生态系统服务。苏Abstrakt Včlanku prezentovane informacie o očakavanom vyvoji这样的V oblasti strednej Europy,我opisana莫žna dynamika lesov V podmienkach zmeny klimy,我vypracovany系统opatreni umožňujucich adaptaciu lesov na zmenu klimy。Na zaklade kolekcie scenarov zmeny klimy波尔identifikovany vyrazny narast intenzity这样的v oblastiach južneho Slovenska马英九ďarska, zatiaľčo v oblastiČeskej republiky一Rakuska流星锤zmena relativne nevyrazna。S ohľadom na tento vývoj predstavuje úprava drevinovsamho zloženia smerom k vyššiemu zastúpeniu sucho tolerujúcich drevín a širšiemu využívaniu proveniencií rezistentných vo i suchu jedno zo základných adaptačných opatrení。V prípade výrazných zmien klímy narast význam umelej obnovy, ktor predstavuje nástroj na zlepšovanie drhovej a genetickej diversity porastov a zvyšovanie rich tolerance vo i suchu。Narastajúci vplyv škodcov súvisiaci s rastúcim vplyvom sucha a ďalších abiotických činiteľov nazna uje potrebu orientovova pestovanie a hospodársku úpravu lesa viac na manažment rizík ako na maximalizáciu produckcie。Konsolidácia system 2013.2013.1 škodlivých činiteľov a širšie využívanie modelov动态škodcov a hodnotenia rizík patria medzi ďalšie dôležité opatrenia podporujúce adaptáciu lesov na zmenu klímy。Všetky uveden opatrenia musia bylovpodporen informáciami získanými na základe dlhodobsamoringu lesa, ktorý však vyžaduje urýchlenú konsolidáciu。systematick a dlhodob realizácia prezentovaných opatrení podporí stabilitu a rezilienciu lesov a vytvorí predpoklady pre udržateľné poskytovanie ekosystémových služieb a funkcií v podmienkach zmeny klímy。

Abstract Nowadays, forest enterprises are facing the persistent need for communication with media, while such situation was not common in the past. Thus, it is necessary to study the principles of media communication under special conditions of forestry, using phenomenological approach. The paper, based on the analysis of theoretical background of communication and media policy, proposes model of the forest enterprise presentation in media, including general principles of communication policy with special emphasis on its effectiveness in non-monetary terms. More specifically, the following issues are addresses in the paper: goal and objectives of media communication as well as basic characteristics of media communication. Then, the irreplaceable components of the model of forest enterprise media communication, including the enterprise communicator role, media communication tools and strategies, are proposed. Finally, the measures of effective media presentation of forest enterprises are discussed.

Abstract The paper presents results of a long-term observation focused on the growth of two selected fir-beech stands in the area of the Eastern Carpathian Mountains, which were established in the past to investigate the effect of different management treatments on the growth and structure of the stands. Attention was paid to changes in the tree species proportion, vertical and horizontal structure, the quantitative production and dead wood. The results of the monitoring of approximately 60-year stands development suggested a reduction of the fir proportion and an increase proportion of beech and maple in the natural conditions. Production characteristics (wood stock, above ground biomass, carbon stock, and dead wood) have reached higher values on the control area. The results suggested that the close-to-nature management of these forest stands has a beneficial effect on their structure and overall development.

Abstract The paper deals with the research of structure and dynamic development of stands in National Nature Reservation Trčkov, located in Protected Landscape Area Orlické Mts. (Czech Republic). The research was carried out in spruce-beech stand with admixed fir and sycamore maple. Two permanent research plots (PRP 1 and PRP 2), for each with area of 0.25 hectare were chosen as an object of our research. FieldMap technology was used for field measurement. Compared PRP were characterized by the same typological, soil, phytocenology and stand parameters, but different method of protection against game damage. Results showed that deer is considered to be limiting factor for successful development of natural regeneration of autochthonous tree species. The tree species proportion of natural regeneration occurred in PRP 1 with fencing was sufficient, contrary to PRP 2 (outside fencing) owing to site and stand conditions. The results of biometric measurements and predicted simulation by Sibyla growth simulator showed multi-layer stand structure and productive spruce-beech stands with interspersed fir and sycamore maple. We also found depleted phase of regeneration according to frequency and tree species proportion, as well as beginning of grow up stadium, especially related to fir and sycamore proportion and/or beech and spruce. It is concluded that growth visualization and simulation confirmed the hypothesis about long-term effect of game to species, spatial and age structure and development of concerned autochthonous population.

Abstract Peatland Norway spruce (Picea abies L. Karst.) forests represent very valuable ecosystems with considerable importance for nature conservation. However, a lot of peatland forests have been drained or used for opencast mining of peat. Since dendrochronological and dendroecological studies on trees growing on peatlands in Europe are not many, this study aimed to reconstruct the impact of drainage to the growth of trees in forest stands older than 100 years in the moment of drainage. Dendrochronological analysis was performed on two 0.25-ha square sampling plots (50*50 m) in two pre-selected stands (control site vs. drained site) with similar natural conditions and age. The mean-value functions of the ring indices, comparing the drained site with the control site, in the period after 1940 revealed very similar radial-growth trends. After the year 1992, when one site was substantially drained, the radial-growth trends not showed any significant change. Likewise, the result of the independent two sample t-test for the period after 1992 has not revealed any substantial statistically important difference in the mean index between the control site and the drained site.
泥炭地挪威云杉(Picea abies L. Karst.)森林是一种非常有价值的生态系统，对自然保护具有重要意义。然而，许多泥炭地森林已被抽干或用于露天开采泥炭。由于欧洲泥炭地树木的树木年代学和树木生态学研究并不多，本研究旨在重建排水时刻对100年以上林分树木生长的影响。在自然条件和树龄相似的两个预选林分(对照林分和排水林分)中，对两个0.25 ha的采样样地(50*50 m)进行了树木年代学分析。1940年以后，排水场地与对照场地环指数的均值函数显示出非常相似的径向增长趋势。1992年之后，当一个地点基本上干涸后，径向增长趋势没有显示出任何重大变化。同样，1992年以后的独立双样本t检验结果也没有显示对照点和排水点的平均指数有显著的统计学差异。

Karst.) forests represent very valuable ecosystems with considerable importance for nature conservation. However, a lot of peatland forests have been drained or used for opencast mining of peat. Since dendrochronological and dendroecological studies on trees growing on peatlands in Europe are not many, this study aimed to reconstruct the impact of drainage to the growth of trees in forest stands older than 100 years in the moment of drainage. Dendrochronological analysis was performed on two 0.25-ha square sampling plots (50*50 m) in two pre-selected stands (control site vs. drained site) with similar natural conditions and age. The mean-value functions of the ring indices, comparing the drained site with the control site, in the period after 1940 revealed very similar radial-growth trends. After the year 1992, when one site was substantially drained, the radial-growth trends not showed any significant change. Likewise, the result of the independent two sample t-test for the period after 1992 has not revealed any substantial statistically important difference in the mean index between the control site and the drained site.","PeriodicalId":56352,"journal":{"name":"Forestry Journal","volume":"19 1","pages":"240 - 247"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82589110","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 The paper presents the results from the analysis of the 45 soil samples collected in 2010 from ten forest nurseries located at different regions of Slovak Republic. In total, 142 species of nematodes belonging to 87 genera were found. Out of them, 32 species are considered as plant feeders - parasites of higher plants, 11 species belong to fungal feeders, 10 species to root-fungal feeders, 8 species of predatory nematodes, 20 species of omnivorous nematodes and 49 species of bacteriovorous nematodes. The highest number of species was found in the Picea abies (94) and Quercus robur (80) rhizosphere. The survey results showed that communities of soil nematodes in forest nurseries are represented by all trophic groups of nematodes, but bacteriovorous, phytophagous and phyto-mycophagous nematodes prevailed and represented about 80% a total nematode fauna of coniferous and deciduous seedlings. The species of Acrobeloides nanus, Cephalobus persegnis, Rhabditis sp. juv.¸ Mesorhabditis sp.juv., Helicotylenchus digonicus, Paratylecnhus bukowensis, Trichodorus sprasus, Filenchus vulgaris, Malenchus exiguus, Tylencholaimus mirabilis, Tylencholaimus stecki belong to the most abundant at this study.

Abstract This review paper summarises the development of forest monitoring in Europe and in Slovakia. Since 1986 Forest Research Institute has been performing monitoring activities at the systematic grid of 16×16 km on permanent monitoring plots of Level I (extensive monitoring) and since 1995 on 9 plots of II. Level (intensive monitoring), which is closely connected with programme ICP Forests and PMS Forests. However, during 1991-1992 monitoring on 1189 plots in the grid of 4×4 km in Slovakia was done by Lesoprojekt Zvolen, which was repeated during the last 10 years as a part of LHP (every year 1/10 territory). This paper describes briefly also surveys and monitoring activities of different monitoring systems, parameters, methods and the perspectives of monitoring of the forest condition
