On an agrosilvopastoral farm in central Italy where Maremmana cattle graze in Turkey oak forests, we evaluated the impact of different livestock densities on stand structure, tree diversity and natural regeneration in four types of grazed areas based on the grazing regime adopted: calf-grazed, high-intensity-grazed, low-intensity-grazed, ungrazed c...
Gli studi effettuati per valutare il ruolo delle matricine nei cedui di castagno concordano nell'affermare che la loro presenza condiziona negativamente la struttura e l'accrescimento dei polloni, limitando in particolare lo sviluppo e la dominanza delle ceppaie. Gli effetti negativi, oltre alla componente cedua, riguardano anche la rinnovazione da...
Per "sistema selvicolturale" s'intende l'insieme di operazioni messe in atto per la coltura, l'utilizzazione e la messa in rinnovazione di un bosco. I sistemi selvicolturali indicati per il governo a ceduo del castagneto variano in funzione degli obiettivi specifici, ma possono essere raggruppati in due diverse categorie di selvicoltura: quella di...
Sporadic valuable tree species and especially Sorbus species have gained importance in forest management as they increase tree biodiversity, ensure a higher resilience of the stand to climate change, and enhance valuable timber production. This paper reports the first results of a trial carried out in Central Italy in a Turkey oak coppice stand (ag...
L'articolo ripercorre le attività di ricerca e sperimentazione condotte dal CREA Centro di ricerca Foreste e Legno, che da 50 anni or sono realizzava protocolli di ricerca nelle tipologie di ceduo più diffuse e ne iniziava un periodico periodico e sistematico monitoraggio che prosegue tutt'oggi. L'obiettivo era ed è quello di dare indicazioni gesti...
In the last decades, releasing standards have become a very common and in some cases even mandatory management options in coppice systems in Europe. As for the chestnut tree, a light demanding and fast-growing species, however, there is a lively debate and a lack of scientific evidences about the pros and cons of releasing standards, especially in...
Aim of study: To verify the short rotation coppices (SRC) aboveground biomass production; to define the best planting intra-row spacing for walnut and poplar growth and wood production, with the last goal to assess the possibility of obtaining competitive yields in comparison to those produced by traditional monocultures.
Area of study: Po Valley,...
Per valutare l’impatto della fauna selvatica sul processo di rinnovazione, sono stati analizzati due casi di studio: uno in una fustaia di pino nero, utilizzata 8 anni fa, in cui parte della superficie era stata recintata; l’altro in un ceduo di cerro di 2 anni per determinare la capacità di ricaccio e l’entità dei danni in funzione dell’origine,

Species interactions in mixed plantations can influence tree growth, resources capture and soil fertility of the stands. A combined approach of tree-ring analyses and carbon stable isotope was used to check tree growth and water use efficiency of two species, Populus alba L. and Juglans regia L., intercropped with each other and with N-fixing or co...
The paper describes the principal techniques and cultural models suitable for common walnut cultivation pointing out the high potentiality of this tree and the limitations of walnut cultivation.
Tree planting on abandoned agricultural land could both restore the soil quality and increase the productivity of economically valuable woody species. Here, we assess the impact of mixed-species tree plantations on soil quality at a site in Central Italy where tree intercropping systems were established 20 years ago on a former agricultural land. T...
Within the activity of the H2020 'WOODnat' project ("Second generation of planted hardwood forests in the European Union") the growth parameters, yield and sanitary conditions of the most important walnut (Juglans spp.) plantations, established in Italy in the 1990s and in Spain starting from 1996, were recorded. One of the objectives of the projec...
The invasion of the Asian chestnut gall wasp Dryocosmus kuriphilus (ACGW) in Europe has caused serious biological and economic impacts on chestnut stands that have been partially solved with the introduction of the biological control agent Torymus sinensis. However, information concerning tree‐ring growth during the ACGW epidemic has been lacking s...
In Italy, forest tree crops cover an area of about 100,000 hectares of farmland: more than half are represented by specialized poplar plantations, while the remaining consists mainly of hardwood broadleaves plantations. The profitability of poplar and hardwood broadleaved plantations, assessed by field data collected on a representative number of p...
Thinning intensity is an important factor affecting forest structure and density and influencing tree growth.
The main objective of the study is to evaluate how the different intensity of thinning can influence, in the short and long term, the productivity and intrinsic water use efficiency (WUEi) of Quercus robur L., a widespread European species....
The management of Italian chestnut coppices has gradually been suspended after World War II, causing a widespread overaging of the concerned stands. In recent years, the renewed interest in coppice wood products increased the need of a solid knowledge on the most suitable restoration practices of overaged coppices.
In this context, a key issue is a...
The goal of this study is to assess the impact of different thinning approaches for coppice conversion into high forest of Turkey oak stands in Italy. The stand structure and the tree/shrub diversity were analyzed in 27 long-term monitoring plots from 7 experimental trials in the Colline Metallifere district (Tuscany, Central Italy) to verify the c...
Premessa Le classificazioni e definizioni esistenti in tipolo-gie dei soprassuoli puri o a prevalenza di castagno lasciano spesso ampi margini per interpretazioni sog-gettive, ciò che può portare a confusioni e fraintendi-menti nella stesura di regolamenti forestali, misure di finanziamento e rilievi inventariali. Il contesto casta-nicolo risulta o...
Introduzione Nei cedui, il rilascio delle matricine è una pratica dif-fusa quasi esclusivamente in Italia e giustificata più dalla consuetudine che dall'effettivo assolvimento delle funzioni attribuite a questa componente. Zanzi Sulli e Di Pasquale (1993) hanno esaminato, attraverso la letteratura scientifica storica, il pensiero selvicolturale uff...
Key message
The adoption of new silvicultural methods and approaches requires an understanding of the differences between those and “old” or “conventional” approaches, along with extensive training to break previous knowledge bias.
Context
Forestry is in transition towards ecosystem-based management, and new silvicultural approaches are appearing w...
Walnut tree species (Juglans spp.) are commonly used for high-quality wood production in plantation forestry. In this paper, the most relevant walnut plantations in Italy and Spain have been reviewed and analysed under a geographic and techni- cian management point of view. Between 2016 and 2019 a total of 96 plantations (15 - 25 years old) were vi...

Climate change alters the thermal environment of animals, affecting animal health, reproduction, and the feed conversion efficiency. Environmental stress and, more specifically, thermal stress directly affect productivity and health of livestock resulting in
significant economic losses. Agroforestry is a land-use strategy to cope with climate chang...
Over the last decades, the abandonment of the traditional management due to many adverse factors caused a general aging of chestnut coppices; this led to an increased mortality of the chestnut stools and a consequent replacement with the entry of other species. Preservation and improvement of the chestnut coppice emphasize the importance of natural...
Forest management strategies for addressing global climate change have become an increasingly important issue. Among forest management practices, thinning is the most commonly applied treatment for improving tree productivity. Thinning is able to decrease competition between the remaining trees and improve stand vigour, thereby effectively increasi...
The relationship between climate change mitigation measures and water is a reciprocal one. Mitigation measures can influence water resources and their management, and it is necessary to realise this when developing and evaluating mitigation options. Indeed, it is important that carbon sequestration strategies consider all environmental consequences...
First results from The European project WoodNat: second generation of planted hardwood forests in EU
Over the last 50 years, many unfavourable factors have led to the abandonment of the traditional management of many chestnut
coppices. This generated a general aging of the stands and a related reduction of the slope stability, emphasizing the importance of natural
regeneration for future forest management.
Natural regeneration from seed contribute...
Mixed-species plantations containing non-nitrogen (N)-fixing species and N-fixing species have the potential to increase the productivity and the ecophysiological performance of the target tree species in comparison to monoculture. However, there are few and conflicting data on the effects of fixed N transfer on species water use efficiency in the...
Coppice management in Italy has traditionally focused on a single or few dominating tree species. Tree-oriented silviculture can represent an alternative management system to get high value timber production in mixed coppice forests. This study illustrates an application of the tree-oriented silvicultural approach in Turkey oak (Quercus cerris L.)...

Tree-oriented silviculture is an innovative approach of forest management aimed at enhancing a limited number of early-selected crop trees whose growth is favored over the full rotation period by applying frequent thinning in their neighborhood. This approach was originally applied to high forests, but can also be applied to coppices to maintain or...
In the past centuries, a notable reduction of lowland forests in Italy was detected as a result of the expansion of intensive agriculture and deforestation activities. According to the National Forest Inventory (INFC 2005), the English oak (Quercus robur L.) is mainly a scattered species distributed across 146,000 hectares of mixed forests. This sp...

In Italy, as in the rest of Europe, tree farming and agroforestry systems can contribute significantly to
domestic wood production, for industrial usage and energy conversion, combining productive
activities with ecosystem services. This has been demonstrated in the last few years by many
research studies carried out at national and international l...
According to FAO, a 12.9% crop land decrease was registered in Europe from 1965 to 2001
and it was particularly evident in Italy (-29.7%). Besides, FAO stated a further reduction of
forest (-1.7%) and cropland (-3.1%) from 2000 to 2013. Over the same period, forest land
increased of 0.7% at European level confirming the positive trend occurred over...
In this contribution we present the results of a Swiss-Italian joint sylvicultural experiment to verify if and how the single-tree-oriented silviculture can be applied to chestnut coppices to enhance timber production for industry and structural timber. The study was carried out in five 7 to 17 years old, pure chestnut coppice stands growing on sit...
