Drought hardening is a nursery technique aimed to enhance early forest plantation establishment under dry conditions, which is a main limiting factors for plantation success. However, the quantitative effectiveness of drought hardening remains unclear. We conducted a meta-analysis to evaluate the influence of different factors in the effectiveness...

Recent model projections and many research results along the world suggest that forests could be significant carbon sinks or sources in the future, contributing in such a way to global warming mitigation. Conversion of coppice forest to high forest may play an important role towards this direction. However, the most effective way for this to succee...

One of the challenges faced by current forestry practice is how to effectively respond to the great environmental and global changes to achieve biodiversity conservation and the demands for timber and other non-wood forest products. Worldwide forestry suggests that the approach of ecological silviculture can provide efficient tools for facing these...

Measuring tree growth rates is an important requirement in many scientific disciplines and forest production sector. The assessment of annual volume growth rates in standing living trees, under ambient field conditions without destroying the tree has so far only been conducted with model approaches or by repeated measurements of tree dimensions in...

Greece, along with most of the countries in the Mediterranean basin, is historically linked with forest fires. Wildfires have always occurred, are happening, and will continue to occur, causing serious problems regarding the sustainability of natural resources. Their frequency, however, has shown a noticeable increase during the last decades; accor...

Purpose of Review The demand for forest tree seedlings is increasing globally, and Sphagnum peat moss is widely used as a component of growing media for container plant production. However, peat extraction is environmentally unsustainable. The forest nursery sector needs to switch to more sustainable alternatives to peat. This review aims to identi...

Purpose: The development of a methodological approach for the estimation of the wildfire danger in a protected area, located near a big city, based on the dominant factors contributing to a fire-prone environment and affect fire behavior. Theoretical framework: Vegetation management in protected areas characterized by sprawling of adjacent urban an...

The relationship between the quality of forest seedlings and their outplanting survival and growth has long been recognized. Various attributes have been proposed to measure the quality of planted seedlings in forest regeneration projects, ranging from simple morphological traits to more complex physiological and performance attributes, or a combin...

The recent Glasgow Climate Pact has recognized the contribution of ecosystems as sinks and reservoirs of greenhouse gases and their importance to achieve the objective of a maximum temperature increase of 1.5 °C. Thus, the knowledge of the long-term storage capacity of the soil organic carbon (C) in forest soils, and the driving factors, are consid...

Measurement of tree growth is needed in many scientific and production sectors, especially in forestry for wood and biomass production. The assessment of annual height increment in standing living trees, under ambient field conditions, is challenging or even impossible. This study develops a new simple non-destructive method for the estimation of a...

Recent model projections and many research results across the world suggest that forests could be significant carbon sinks or sources in the future, contributing in a such a way to global warming mitigation. Conversion of coppice forest to high forest may play an important role towards this direction. This study deals with the estimation of biomass...

In the past few years, the continuous expansion of urban development has created mixed forested, agricultural, and urban areas. These areas are called the wildland–urban interface (WUI), and they are characterized by increased human activities and land-use conversion, and they usually contribute to a high risk of wildfire occurrence. In the case of...

Forests host important plant biodiversity. Nevertheless, due to climate change and human disturbances, the floristic quality of forest ecosystems is degraded. Greek peri-urban forests biodiversity is threatened by anthropogenic activities such as forest fragmentation, pollution, garbage, etc. Measurement of biodiversity status and the floristic qua...

Floodplain forest ecosystems are considered important ecosystems for their high ecological and economical values and functions. Last decades human activities on floodplains have resulted in a large reduction of these ecosystems or/and high degradation, while in some cases they severely disrupted the regeneration of riparian tree species of the Sali...

Κατά την περίοδο της πανδημίας του covid-19 και των μέτρων για την αντιμετώπιση της (από 3/2020 έως και τον 5/2021) ο μαζικός τουρισμός κλονίστηκε. Οι ανάγκες για κοινωνική αποστασιοποίηση ευνόησαν τις επισκέψεις σε περιοχές φυσικού κάλους και στα δάση, όπου ο οικοτουρισμός με τα ιδιαίτερα χαρακτηριστικά του (επισκέψεις στην ύπαιθρο από μικρές ομάδ...

Είναι γενικά αποδεκτό ότι τα δάση συμβάλλουν στη δέσμευση του άνθρακα και στη μείωση της συγκέντρωσης του διοξειδίου του άνθρακα της ατμόσφαιρας, στο οποίο αποδίδεται κατά κύριο λόγο η υπερθέρμανση του πλανήτη. Παρόλη όμως τη γενική παραδοχή, ο ακριβής προσδιορισμός των ποσοτήτων άνθρακα που δεσμεύονται στα δασικά οικοσυστήματα είναι μια δύσκολη δι...

A critical issue in effective post-fire regeneration and re-establishment of a burnt forest is the stage concerning the burned stands. When stands are mature and produce seeds, the regenera-tion can theoretically be achieved, while in the case of immature stands, they may not be able to produce enough quantities of germinable seeds that can secure...

Solanum elaeagnifolium Cav. is one of the most invasive plant species worldwide that colonizes crops and human disturbed lands, while it appears at the edge of forest ecosystems. Its control still remains an unsolved problem around the world. Understanding its distribution under predicted climate change, could contribute to an effective management...

Reforestation constitutes a challenge in post-fire ecosystem restoration, although there are limitations such as species and genotype selection, planting and management design, and environmental conditions. In the present study, the basic issue is the longevity of Abies cephalonica Loudon—the Greek fir seedlings planted extensively in Parnitha Nati...

Pinus nigra is one of the most widely used tree species for reforestation within its geographical distribution, as well as being a potential substitute for other tree species in Central Europe under future climate scenarios. P. nigra is transplanted into the field as two-year or three-year old seedlings because of its relatively low growth rate in...

This study was undertaken to identify seedlings morphological characteristics that ensure better field performance Cercis siliquastrum L. The purpose of this research specifically, was to ans...

The aim of this study was to investigate the methods that increase the germination of the native species Cercis siliquastrum and Carpinus orientalis, whose seeds exhibit dormancy. Seeds of C. siliquastrum were collected from a natural habitat and an urban environment, and seeds from both origins were given 6 different dormancy-breaking treatments....

In Europe, the establishment of the Natura 2000 network is one of the main actions that has been undertaken to contribute to the maintenance of biodiversity. However, the management system of sites included in the network is under question. The aim of this study was to assess the natural resource management applied to the National Park of the wetla...

Field performance can be predicted by evaluating nursery stock quality, but optimal morphological variables for use in these assessments may vary by species espe-cially under dry Mediterranean conditions. Our objective was to identify initial seedling morphological characteristics that successfully predict field performance of five Mediter-ranean s...

Nine years after a wildfire, above-and below-ground morphology of Pinus brutia Ten. saplings and the microsite factors prevailing in understorey (unburned area) and postfire conditions (burned area) of the Forest Park of Thessaloniki were studied.
