The easy implementation of a nature-based solution (NBS) to address prompt stabilisation burnt areas may be crucial in the Mediterranean forest environment. A plot scale hydrological and ecological survey was conducted pine Aspromonte Massif (southern Italy) affected by high fire severity summer 2021. response 30 rainfall event groups is analysed monitoring nine sloping plots distributed into three blocks (forested according pre-fire situation, with randomly directed felled logs manually...

In the Mediterranean basin, coniferous reforestation mainly comprises forest stands highly susceptible to fires. When silvicultural treatments have not been performed for decades after plantation, these often exhibit high vertical and horizontal tree density, along with a significant occurrence of lying standing deadwood, thereby increasing fuel load. On average, pine forests are characterized by values above-ground biomass, ranging from 175 254 Mg ha−1 younger older ones, respectively. The...

In the middle of XIX century, Calabrian pine was planted in southern Italy to increase forest cover mountainous areas. Many these stands were never managed, since they considered non-profitable for wood production. Therefore, order promote timber value, it is fundamental study, more deeply, characteristics and management options this species. The acoustic technologies applied predict mechanical physical properties are well-established practices research. we hypothesized that tree stand...

The effects of initial planting densities on the distribution above-ground biomass Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. menziesii) were investigated in a plantation southern Italy. Allometric equations designed for under study used to estimate and particular partitioning stem crown compartments. A comparison between estimated with allometric constant expansion factor (BEF) from Italian National Forest Inventory (INFC 2005) was carried out. Moreover, BEF calculated as ratio...

Mixed-species forests may deliver more forest functions and services than monocultures, as being considered resistant to disturbances pure stands. However, information on wood quality in mixed-species vs. corresponding is poor. In this study, nine plots grouped into three triplets of stands European beech Calabrian pine (three dominated by beech, pine, plots) were analysed. We evaluated tree growth through dendrochronological approaches non-destructive technologies (acoustic detection),...

The assessment of the current annual increment forest standing volume (CAI) is a fundamental tool to support management and planning. A suitable approach such an end rely on growth yield models. However, this kind models are often not available for many countries and/or locations species. Furthermore, they may become obsolete due potential changes in environmental silvicultural conditions. Such shortcomings be distinctively detrimental context inventories. Several methods have been proposed...

Sclerophyllous vegetation contributes to the formation of forest resources in Mediterranean biome that turn provides an important resource terms ecosystem services. Despite this, scientific knowledge sclerophyllous vegetation, particular with regard their root systems, is fragmented. This review takes into account research on below-ground biomass different contexts where there a climate. In particular, authors analyse investigative approaches used studying roots, main topics covered by...

The present study was focused on how cardinal directions inside gaps of different sizes (small, 200 m2; medium, 400 and large, 600 m2) can affect soil characteristics tree regeneration. Additionally, the effects gap size growth dynamics trees outside were evaluated. carried out in a European beech stand located Aspromonte National Park (Southern Apennines, Calabria, Italy). Microclimatic variables, physical, chemical, biochemical properties, natural regeneration density, density assessed....

Tree-related microhabitats (hereafter TreMs) are structures occurring on trees, such as rot holes, cavities, large nests, mould, fruiting bodies and mycelia of decomposer fungi. TreMs have been widely recognized important substrates useful for biodiversity conservation in forest ecosystems, they can be used indicators describing monitoring naturalness. However, most studies the occurrence mainly done ecosystems Central Europe, while less research has conducted Mediterranean mountain forests....

CO2 fluxes from soil, together with soil water content and temperature have been measured over one solar year in an even-aged beech forest (Fagus Sylvatica L.) southern Italy. We investigated the effects of three different harvested biomass removal treatments (traditional, innovative, unharvested control) on respiration (Rs) plots May 2014 to April 2015, aim evaluate such silvicultural practices respired floor. The influence moisture was also analysed. Rs showed large variations among...

Between XVIII and XX centuries, the forest resources in Calabria region (southern Italy) were intensively exploited only political strengths, relatively recent, led to a re-establishment of cover. Thanks these actions, from 1957 1980, reforestation recovery activities interested 153.000 ha cover increased by 32%, with consequent reduction erosion processes mountainous areas. In present study we analysed three monospecific conifer stands, reforested 50 years ago, Aspromonte National Park,...

In Italia vi sono diversi boschi nei quali l’assenza di impatti significativi legati alle attivita umane per un periodo tempo sufficientemente lungo, ha consentito dinamiche naturali esprimersi, dando luogo a cenosi strutturalmente complesse e ricche biodiversita. Per tali caratteristiche, questi popolamenti forestali possono essere considerati vetusti. L’analisi della struttura, componente viva quella morta, consente individuare definire lo stadio evolutivo del bosco il grado complessita...

The initial data of a long-term research programme aimed at determining the silvi- cultural choices for management ageing holm oak coppices are reported.The various treatments being tested following: A and B, respectively, with 50 250 reserve trees per hectare, all same age; treatment C 140 three different ages; D, conversion into high forest; E, natural evolution (the control).A total 15 permanent plots were established (five x replicates) experimental design used is that randomized...

The work has examined an area of the central-northern part Calabria, in province Cosenza (Southern Italy), reforested between 1955 and 1960 with black pine trees on 1,535 hectares, divided separate blocks different surface. Applying a methodology integrated phases we estimated fuel reduction by thinning corresponding caloric energy separately for various areas. Results show that reducing stand density, average 48% tree number, 18.0% basal volume,assuming total combustion would affect only...

This paper reports the results of first fire hazard reduction experiment in Italy which integrates thinning and prescribed burning. The study was conducted Aleppo pine stands a high fir-risk area Calabrian Region. Two with different stem density were selected. design included: i) burning followed by selective from below stand lower tree density; ii) selected higher density. Light/moderate intensity treatments applied at both sites June-July 2013. Prescribed May 2013 March 2014. Data on fuel...
