Soil degradation and desertification pose significant threats to Mediterranean ecosystems. The marginal maquis shrublands of Messara in Crete, Greece, exemplify poor land management under conditions, where overgrazing influences vegetation composition density, leading extensive soil erosion (Daliakopoulos et al., 2017). As ecosystem restoration becomes a global priority, the complete removal livestock revegetation efforts have become common throughout Mediterranean. However, few these...

Silver fir (Abies alba Mill.) used to be an important species in the region of what is Czech Republic today. Its return forest ecosystem more than desirable, mainly because it can utilised transition management close-to-nature establishing multistorey, uneven-aged or mixed forests. A total 15 unestablished stands arising on clear-cut areas Beskydy Mts. (caused by storms and subsequent gradation bark beetle) period 2015–2018 were selected, some which established large without being influenced...

We focused on the ability of one-year-old and two-year-old plants Paulownia Clon in vitro 112® to sprout grow branches, their pruning for best possible growth a plantation Střelice u Brna. Furthermore, we carried out selected parts that comprised: spring pruning; reduction angle between stem axis one new growing sprout; year-long pruning. The sprouting capacity was high—up 56% (one-year-old plants) 50% (two-year-old plants). Branches grew 34% all 57% plants. method seems be keeping or stump...

In the period of ongoing global climate change, ecosystems, including Central European forests, face significant challenges such as summer droughts and heat waves, which increase risks also for beech (Fagus sylvatica L.), an important dominant broadleaved tree species in this region. This article provides a comprehensive review current knowledge on adaptation strategies response to changing climatic conditions, highlighting its ecological demands, development taxonomy, economic importance...

Monoculture forests formed by Fagus sylvatica L. belong to one of the most sensitive forest ecosystems, mainly at low altitudes. Cultivation this species in mixed stands should reduce its sensitivity drought vegetation period, which is why we researched water balance pure-beech (i.e., monoculture) and beech–oak–linden mixed) forest. This research was carried out Drahanská vrchovina Czech Republic period 2019–2021. The total precipitation measured, together with partitions throughfall...

A private owner established a plantation of semi-arid hybrid Paulownia Clone in vitro 112® near the village Střelice u Brna 2016. We split according to terrain micro-relief (into three expositions: South slope, Plain area and North slope) applied biotechnology planting two parts: each with into 20 30 cm holes diameter). tested different winter protection techniques for above belowground plant organs. The results suggest that plants inside survive grow better than those ones, regardless...

Due to an increasing risk of further damage forests, forest managers are considering introducing alternative direction for their future development – via the cultivation mixed forests. At middle altitudes in Czech Republic, oak-beech-linden stand is most natural type, and we tried answer three main questions: (<i>i</i>) How various thinning types affect dendrometric parameters quality stand; (<i>ii</i>) long works on this until it loses its effect; (<i>iii</i>) develops spontaneously after...

The size of area plantations fast-growing tree species, established on agricultural land in the Czech Republic (CR), is rise. In order to gain saw timber, it necessary choose other species (example: Salix spp. and Populus spp., their resulting product wood chips), one which could be Paulownia 2015, an experimental plot with tomentosa two hybrids Shan-Tong Hybrid 9501 were South Moravia. plants periodically pruned up a height 3 m. After six years, had mean 9.4 m DBH 12.8 cm, P. 7.3 10.3...

Paulownia spp. comes from South-East Asia, where there is a tradition of its cultivation. Social pressure, in favour the use renewable sources energy and sustainable agriculture, on rise. In this context, agroforestry has become significant topic interest. could be one species utilized field. That why, 2014, experimental system, which was intended for production fodder farm animals, also saw timber, established warmest areas Czech Republic. The aim research to evaluate potential Bellissia®....

In this paper we are interesting in mathematical description of reforestation system Drahanska highlands, which can be found the Czech Republic. We estimate parameters revenue and cost functions predefined according to formulation underlying optimal control problem. Data related wood processing economy available limited form only, because companies do not present their costs profits regular way. To cover overall situation forestry management employ simulation techniques, provide data...

In forestry, it is still common to plant the seedlings of and cultivate Norway spruce (Picea abies L. Karst) at lower altitudes; however, climatic change that has been occurring increases evaporative demands in these areas. As a result, evidently suffers from drought, withers loses its power grow, thus, influencing stem thickness tree-height growth, as well biomass production. Therefore, growth production young (5-, 15- 25-year-old) stands altitudes (i.e., 200 500 m a.s.l.) was surveyed,...

This contribution presents initial qualitative results and discussions when addressing the particular dynamic optimization problems in Czech forestry management. First, we analyze deterministic infinite time horizon optimal control model aimed to determine paths for plantations of various mixed forests Morava region Republic. Second, problem path subsidy rates is established its solution via using simulated data suggested. The at foremost aim presentation present research topic itself...

Abstract Needed precipitation or supplied water is not known for mostly hybrids. Therefore, we chose one species Paulownia tomentosa and four hybrids - P. bellissia®, Clon in vitro 112®, Shan Tong Hybrid 9502. We found out how three types of watering affect their height thickness increment, amount leaf biomass area if the reaction plants these species/hybrids to different. planted 30 each into plant pots under a shelter. At end growing season, measured total heights plants, lengths...

Paulownia is a deciduous fast-growing tree with intensive sprouting ability and well adapted to various climatic soil conditions. Its native area extends from the middle lower section of Yangtze River. The aim our research was test potential Clon in vitro 112® for production saw timber conditions Czech Republic. In 2016, three private plantations were established—Střelice, Vlčatín Vorel. parameters that measured total height, height live above-ground part each plant after winter, stem...
