More frequent heatwaves and drought increase the flammability of the vegetation; the abandonment of rural land produces 30.000 ha of newly afforested areas each year; and the wildland-urban interface is expanding with the sprawl of urbanized areas. However, forest fires are rarely understood and managed in their complexity. The public opinion is often misinformed on the causes and consequences of fires in the forest. Moreover, fire management relies almost exclusively on extinction and emergency response, resulting in high costs and limited efficacy versus extreme fire seasons. We advocate to increase the role and investments in wildfire prevention, which can be carried out by fuel-oriented silviculture, such as facilitating less flammable species or prescribed burning, in order to reduce the flammability of the vegetation and mitigate fire intensity in high-leverage areas. A centralized structure is necessary to implement such a strategy and coordinate the competences and actions of all local administrations and actors involved.</p><p><b>Keywords</b>: Forest Wildfires, Forest Management, Climate Change</p><p><i>Forest@ 14 (4): 202-205 (2017)</i> - doi: 10.3832/efor2537-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Bovio G, Marchetti M, Tonarelli L, Salis M, Vacchiano G, Lovreglio R, Elia M, Fiorucci P, Ascoli D Commenti & Prospettive 2017-07-19 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

In Mediterranean Europe, two millennia of human exploitation deeply altered the structural complexity of the native forests. Some animal groups, including insects, may be used as a proxy of such changes. In this paper we explored the possible effects of forest management on the functional diversity (species traits) of carabid beetle communities. Three old-growth forests of the Sila National Park were sampled by pitfall traps set up in pure beech, beech-silver fir and Calabrian black pine forests. In each forest, five managed vs. five unmanaged stands were considered. Managed sites were exploited until the sixties of the past century and then left unmanaged. More than 6000 carabid specimens belonging to 23 species were collected. The functional diversity in carabid groups is influenced by forest management especially in beech and beech-silver fir stands. Body size, specialized predators, endemic species and forest species were negatively affected by stand management. On the contrary, omnivorous ground beetles populations (or species) with a high dispersal power (macropterous) and large geographic distribution were positively influenced by stand management. In pine forests the old-growth community seems less sensitive to past management and more affected by soil evolution. Soil erosion and disturbance may reduce species diversity of ground beetles. Anyway, the composition of the carabid community shows that 50-60 years of forest restoration are enough for the reconstruction of a fairly diverse assemblage reflecting a “subclimax” situation.</p><p><b>Keywords</b>: Functional Diversity, Species Traits, Forest Management, Old Growth Forests, Bio-indicators</p><p><i>Forest@ 14 (3): 162-174 (2017)</i> - doi: 10.3832/efor2351-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Mazzei A, Gangale C, Laurito M, Luzzi G, Menguzzato G, Pizzolotto R, Scalise C, Uzunov D, Brandmayr P Articoli Scientifici 2017-05-15 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

The AlForLab project is part of the Cluster MEA (Materials Energy Environment) addressed to the Calabria Region. Estimating the main dendrometric variables of Calabrian forests using models based on publicly available remote sensed data is one of the main purposes of the project. This paper describes the procedures used to develop several thematic maps (raster and vector) of timber volume and phytomass to be used in planning and management activities at both regional and forest property scale, as well as for felling plans, logging projects etc. We used public LiDAR data at medium-low resolution (1.6 pts m-2), acquired on about 90% of Calabrian territory in the frame of a national remote sensing programme of the Italian Ministry of the Environment. Field data from the second National Forest Inventory (INFC 2005) on 311 sample points were used for model calibration, as well as new field data acquired specifically for AlForLab project on 143 angle count samples. A series of regression models to predict volume and its corresponding aboveground biomass (dry and fresh weight) were developed and digital maps at different spatial resolutions were produced, as well as their estimate uncertainties. These models and their mapping products are also an important part of the new-establishing forest Decision Support System CFOR. The adopted models, though based on the same mathematical equation, have specific coefficients for different species and groups of species, according to a forest type classification system compatible with the fourth level of Corine Land Cover. In this way it is possible to apply the models without accessing more detailed forest type maps. All estimation methods and procedures are consistent with national forest inventory models, and with the other new tools proposed by AlForLab project to estimate timber volume, such as the regional tariffs and the field sampling inventory procedures. R2 adjusted values (for models at the highest typological detail) are between 60% and 85%, whereas uncertainties of timber volume estimate (ESS%) range from 25% (for main forest species) up to 50% (for less spread forest types). All processing steps to produce digital maps were performed on open-source environment (R and QGIS).</p><p><b>Keywords</b>: ALS, LiDAR, Timber Volume, Forest Biomass, Estimation Models, CHM, AlForLab</p><p><i>Forest@ 14 (3): 175-187 (2017)</i> - doi: 10.3832/efor2399-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Scrinzi G, Floris A, Clementel F, Bernardini V, Chianucci F, Greco S, Michelini T, Penasa A, Puletti N, Rizzo M, Turco R, Corona P Articoli Scientifici 2017-05-15 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

The AlForLab project, a Public-Private Laboratory which is part of the Cluster MEA (Materials Energy Environment) addressed to the Calabria Region (southern Italy), has gained great benefit by using LiDAR data acquired in the frame of a national remote sensing programme of the Ministry of the Environment and Protection of Land and Sea. This kind of LiDAR data, distributed in raster format and publicly available for research and non-profit purposes, have proved to be a suitable tool to support forest management. Their usage, however, has required the recognition and correction of non-forest elements included in the Digital Surface Model (DSM), like electric powerlines, wind turbines, sub-vertical rocks and viaducts. Such outliers, if remaining into the Canopy height Model (CHM), can generate potential errors in application of LiDAR-based prediction models. This paper proposes some semi-automatic pre-processing procedures, directly applicable on raster data, in order to obtain a CHM without non-forest elements. The methods described here have been developed in open-source environment (R and QGIS). The correction procedures carried out were tested in three municipalities having forest area between 1700 and 5400 ha, and characterized by different types of outliers. The performances of the methods were evaluated by comparing the estimated forest volume obtained before and after their application. Although low total volume changes were observed on the entire study areas (about 0.5%, corresponding to 1500 to 7200 m3), more significant effects, tens to hundreds cubic meters per hectare of overestimation, can occur in stands or forest compartments with a high presence of outliers. In conclusion, the proposed methods have proved to be suitable to achieve a reliable CHM for forest applications.</p><p><b>Keywords</b>: Outlier, Timber Volume, Normalized DSM, Canopy Height Model</p><p><i>Forest@ 14 (3): 188-201 (2017)</i> - doi: 10.3832/efor2328-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Floris A, Penasa A, Michelini T, Puletti N Articoli Scientifici 2017-05-15 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

The main studies focuses on three aspects: ecosystem services potential supply, demand and use. The potential supply is defined as the ecosystem biophysical capacity to supply services, while the demand represents the amount of service desired by the society. The third aspect considers the current use of a ecosystem service in order to satisfy the social demand. This study focused on the evaluation of social demand on ecosystem services provided by forests at local level (Calabria region) under the project “ALForLab”. The main objective of the present study is to analyze the stakeholders’ opinions and preferences of forest sector in Calabria Region about relevance of forest ecosystem services and categories of ecosystem services. The study, conducted in four areas (Pollino, Sila, Catena Costiera and Serre Calabre), was structured in three steps: (i) identification and classification of stakeholders (stakeholder analysis); (ii) administration of a questionnaire to the previously identified stakeholders; (iii) statistical analysis of the data collected by questionnaire. Stakeholders’ opinions and preferences were analyzed in order to highlight the differences between study areas and groups of stakeholders. At the end of the stakeholder analysis, 320 stakeholders were identified and contacted, 71 of whom filled in the questionnaire (response rate of 22%). The results show that the two main categories of ecosystem services are the supporting services and regulating services. According to the stakeholders’ opinions the three most important forest ecosystem services are: biodiversity, landscape and hydrogeological protection. Landscape is particularly important because it is strictly linked to the cultural value and social identity of a territory. This survey show that the characteristics and peculiarities of each study area are the main factors that influence the stakeholders’ preferences on single elements of the landscape. In the study areas characterized by a high natural value (Pollino, Sila and Serre Calabre) the stakeholders consider the natural elements of the landscape (forests and water bodies) as the most important, while in the most urbanized study area (Catena Costiera) the anthropic and cultural elements have a key importance. Finally, the stakeholders consider the forest fires, the illegal cuttings and the forest management abandonment the three main important threat factors to forests functionality in Calabria.</p><p><b>Keywords</b>: Provisioning Services, Regulating Services, Cultural Services, Supporting Services, Stakeholders, Social Preferences, Calabria Region</p><p><i>Forest@ 14 (2): 143-161 (2017)</i> - doi: 10.3832/efor2219-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Pastorella F, Maesano M, Paletto A, Giacovelli G, Vivona S, Veltri A, Pellicone G, Matteucci G, Scarascia Mugnozza G Articoli Scientifici 2017-04-12 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

Forest certification is a valuable instrument for environmental protection and a useful tool of green marketing for forest-wood chain enterprises. In the last decades, in developed countries there has been increased consumer awareness of environmental protection and environmentally friendly wood products. This consumers’ attitude is related to the consumers’ willingness to pay a premium price for environmentally friendly wood products. In the international literature, some studies have investigated the consumers’ willingness to pay (WTP) for several certified wood products with different prices, while few studies have analyzed the willingness to pay of manufactures and enterprises of forest-wood chain for certified wood products. In addition, in the international literature there is a knowledge gap concerning the manufactures or consumers’ willingness to pay for local wood products compared to equivalent products from other geographical areas. Starting from these considerations, the main aims of this study are: (1) to analyze the wood manufactures’ willingness to pay a premium price for certified wood products; (2) to investigate the wood manufactures’ attitudes and willingness to pay for regional/local wood products. The study was conducted as part of the “Ambi.Tec.Fil.Legno” project involving 127 manufactures and enterprises of forest-wood chain located in Calabria region. At the end of the questionnaire survey, the information provided by 40 manufactures and enterprises of forest-wood chain were processed and analyzed (response rate 31.5%). The results show that the main factors that influence the purchase decisions of enterprises are the trust in the seller and the durability of the product. Concerning the manufactures’ willingness to pay for certified wood products, 40% of sample of manufactures is willing to pay a premium price with a mean value of 1.55%. A similar percentage of wood manufactures and enterprises (40%) are willing to pay a premium price to purchase local wood material with a mean value equal to 3.25%. The results of this study can support the decision makers in the definition of new strategies to enhance the forest sector in Calabria highlighting the potential benefits of forest certification and use of local wood at regional level.</p><p><b>Keywords</b>: Sustainable Forest Management, Willingness to Pay, Forest-wood Chain, Wood Manufactures And Enterprises, Calabria Region</p><p><i>Forest@ 14 (2): 107-123 (2017)</i> - doi: 10.3832/efor2174-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Paletto A, Notaro S, Pastorella F, Giacovelli G, Giovannelli S, Turco R Articoli Scientifici 2017-04-03 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

We identified a break-even point in its implementation under different scenarios in order to highlight the economic sustainability limits, expressed in terms of m3 or tons of processed product. The results showed that the use of RFID technology along the supply chain could lead to an effective operational simplification and to a more efficient use of resources. Based on the average market prices for timber (80-120 € / m3), the implementation of RFID technology led to an increase in timber price by 8% under the worst scenarios. This suggests that the use of open source technologies for wood traceability is already feasible and economically sustainable, as 40% of private companies stated their willingness to pay a premium price (on average 3.25% higher) for purchasing certified local wood products in Calabria. Moreover, we expect a further reduction of tags and hardware costs in the next future, up to half the costs estimated in this work, thus making the application of such technology to timber traceability even more affordable.</p><p><b>Keywords</b>: Precision Forestry, Traceability, Tag, RFID, Open Source, Economic Sustainability</p><p><i>Forest@ 14 (2): 124-134 (2017)</i> - doi: 10.3832/efor2267-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Sperandio G, Costa C, Figorilli S, Pallottino F, Scrinzi G, Colle G, Proto AR, Macrì G, Antonucci F, Menesatti P Articoli Scientifici 2017-04-03 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

However, these services, which are crucial for human well-being, are not sufficiently recognised and rarely included into forest planning. The project LIFE+ Making Good Natura aims to develop innovative governance models for agro-forestry sites of the Natura 2000 network based on ES to achieve new possible mechanisms of (self)financing. This paper provides insights into the biophysical and monetary valuation of nine ES, which were quantified for selected Natura 2000 sites in different regions of Italy. Based on our results, Payments for Ecosystem Services (PES) are discussed in relation to forest planning and management suggesting a new concept for the forest planning. Management plans should hence integrate different financial flows, not only wood or timber, but also different ES which provide more interesting income.</p><p><b>Keywords</b>: Forest Planning, Forest Management Plan, Ecosystem Services, Natura 2000, Payments For Ecosystem Services</p><p><i>Forest@ 14 (2): 99-106 (2017)</i> - doi: 10.3832/efor2235-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Gaglioppa P, Guadagno R, Marino D, Marucci A, Palmieri M, Pellegrino D, Schirpke U, Caracausi C Articoli Scientifici 2017-03-28 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

In Italy, the value of bioeconomy is 251 billion € and more than 1.7 million of workforce is employed in this sector. The forest-wood chain cover about 15% of total value of bioeconomy. The consultation draft of Italian Bioeconomy Strategy was presented on November 22, 2016. This document identifies three macro-sectors (agrifood, marine bioeconomy, forestry and biobased industry) with the respective objectives and priorities. In addition, some Italian regions are organizing to devise a regional strategy detailing the key points of the EU Bioeconomy Strategy and Italian Bioeconomy Strategy in accordance with local peculiarities. In order to develop a regional strategy for the forest sector it is important to investigate the social demands and needs involving the local stakeholders. The aim of the study is to investigate the stakeholders’ opinions of Calabria Region (Italy) about the priorities of forest-wood chain to include in the future regional bioeconomy strategy. The stakeholders’ opinions were collected through the face-to-face administration of a structured questionnaire to 99 local stakeholders. The respondents assessed the importance of a set of objectives aimed to enhance the forest-wood chain at local level (economic exploitation of wood products; diffusion of forest certification; orientation of production to market demand; coordination of forest-wood-energy chain’s actors; implementation of environmental and cultural forest values; improvement of the level of mechanization in wood processing; improvement of the efficiency of forestry workers). In addition, the respondents assessed the capacity of some specific activities to achieve the above mentioned objectives. The collected data were used to define two strategies aimed to enhance the forest-wood chain in Calabria Region. The results show that for the interviewed stakeholders the main three objectives are: the implementation of environmental and cultural forest values, the improvement of the efficiency of forestry workers, and the diffusion of forest certification. In addition, the stakeholders highlighted the importance of the activities of environmental education for the citizens and the professional training courses for the forest operators. Finally, the diffusion of forest certification is a key issue for the interviewed stakeholders. This issue can be achieved facilitating the access of the certified products to the market and creating a chain-of-custody system for the wood products.</p><p><b>Keywords</b>: Bioeconomy, Public Participation, Consultation, Forest Certification, Environmental and Cultural Forest Values</p><p><i>Forest@ 14 (1): 34-48 (2017)</i> - doi: 10.3832/efor2277-013<br/><a href="" target="_blank"></a></p><hr size="1"/> Paletto A, Giacovelli G, Matteucci G, Maesano M, Pastorella F, Turco R, Scarascia Mugnozza G Articoli Scientifici 2017-02-27 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

Comparison of Lepidoptera community in silver fir and black pine stands in Calabria (southern Italy). The main coniferous forests of Calabria (Italy) are certainly the Calabrian black pine (Pinus nigra calabrica) forests of the Sila massif and the silver fir (Abies alba) forests of the Serre Vibonesi. Despite these woodlands are of great importance both economically and from a conservationist point of view, biodiversity of moth has been investigated in a non occasional way only for the Sila Calabrian black pine forests, while the silver fir woods of the Serre have been only recently the subject of studies. Apart from increasing the knowledge on the biodiversity of the nocturnal Lepidoptera hosted by Calabrian coniferous forests, the aim of this study was to compare the sampled communities to find out the main differences and their causes. The sampling was conducted in 9 sites for each forest type, distributed so as to cover the different development stages of ecological succession, from open areas to mature woodlands. A light trap was monthly placed at each site from May to November 2015, for a total of 126 nights/trap. The two communities showed low similarity indices (Classic Jaccard = 0.396; Sorensen Classic = 0.568), due both to the component trophically linked to the dominant forest species and to the component linked to the herbaceous layer. In fact, the dominant species in the Calabrian black pine wood and in the silver fir wood (Thera firmata and Macaria liturata, respectively) are absent or only occasionally present in the other forest type, and the community linked to the herbaceous layer is much better represented in the Calabrian black pine forest (29.7% of the total) than in the silver fir forest (14.9%). The arrangement of the Sila landscape, where Calabrian black pine forests alternate with pastures, shrubs and cultivated fields, seems to be the cause of the increased presence of species related to non-forest vegetation layer, while the micro-climatic conditions of the silver fir forest, more humid and temperate, favor the presence of a limited share of species trophically associated with herbaceous plants, which, however, have a high bio-geographical interest.</p><p><b>Keywords</b>: Lepidoptera, Biodiversity, Communities</p><p><i>Forest@ 14 (1): 49-59 (2017)</i> - doi: 10.3832/efor2241-013<br/><a href="" target="_blank"></a></p><hr size="1"/> Infusino M, Scalercio S Articoli Scientifici 2017-02-27 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

The system, called TaCAL, was based on the double entry volume and biomass functions of the Italian National forest Inventory - INFC 2005 -, and was built studying the height/dbh relationships on 2300 trees measured during the INFC campaign in Calabria, on over 300 sampling plots randomly distributed. For each of the 20 species, or group of similar species, the tariff system is articulated into 9 h/d relationship curves, which are in turn related to corresponding single entry tables of tree volume (stem and branches with dbh above 5 cm), and respective biomass tables. According to INFC 2005 stereometric equations, TaCAL system is suitable for both high forests and coppices. TaCAL provides a uniform volume and biomass estimation system for all main forest species of Calabria as well as, under certain conditions, a unique criterion of expression of the site fertility. TaCAL tariff system has already been integrated into the construction of forecasting models of timber volume and biomass based on angle count samplings, at forest management scale. TaCAL has also provided the basis for ground truth volume estimates to develop forecast models through remote sensing LiDAR data.

The species in a community have different behaviors and are more or less influenced by the surrounding landscape diversity. The effects of landscape diversity on moth communities are significant when the appropriate spatial scale is considered, which depends on the ecological needs and dispersion abilities of species. In this study we assessed the relationships between landscape diversity at different spatial scales in four different forest Calabrian scenarios, identified by using the CORINE Land Cover, and moth diversity. Nocturnal Lepidoptera were sampled in beech, chestnut, Calabrian black pine and fir forests by using LED light traps. In each forest type 9 traps were positioned, in a total of 36 sample plots selected by the maturity of forest. The diversity of Lepidoptera communities was related to landscape diversity, considering each sample plots as the center of the surrounding landscape analyzed with different buffers (500m, 1000m, 2000m, 3000m, and 5000m). Diversity moth-landscape correlations were performed for: (i) all 36 sample plots; (ii) only broadleaves forest sites; (iii) only conifers forest sites; (iv) only forested plots; (v) only non-forested plots. Our results suggest that landscape composition in forest ecosystems, both at small and medium spatial scale, have a driving role in determining moth communities diversity, pointing out that the landscape structure is a parameter to taking in account for the sustainable management of forests.</p><p><b>Keywords</b>: Lepidoptera, Diversity, Landscape Ecology, CORINE Land Cover, Calabria</p><p><i>Forest@ 14 (1): 75-83 (2017)</i> - doi: 10.3832/efor2296-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Greco S, Coluzzi R, Imbrenda V, Infusino M, Simoniello T, Scalercio S Articoli Scientifici 2017-02-27 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

Forest ecosystems play a multifunctional role and host an important portion of the whole biodiversity, particularly in the Mediterranean area. Remote sensing technologies provide a unique way to obtain spatially extensive information on forest ecosystems, but relatively few studies used such information to evaluate forest habitat and biotic diversity. In this paper we evaluate the effectiveness of remote sensing to predict forest diversity by linking remotely sensed information with diversity metrics obtained from ground measurements of butterfly diversity. The field work was carried out in Calabria in four different forest types (beech, chestnut, black pine and silver fir forests). The sampling of Lepidoptera was carried out by LED light traps. We positioned 9 traps per forest type, for a total of 36 sites chosen to sample the different stages of forest succession in each forest type. Samples were carried out once a month from May to November 2015. Data from in situ butterfly measurements were compared with above ground forest biomass estimated from airborne LiDAR with NDVI estimated from Landsat 8. Results indicated that the Geometridae/Noctuideae ratio of lepidopteran communities was significantly correlated with the tree biomass, its distribution among tree size classes and the NDVI. The Geometridae/Noctuidae ratio, therefore, represents an index easy to calculate, which can be employed to integrate data acquired from remote sensing in order to obtain continuous spatial estimates of forest naturalness.</p><p><b>Keywords</b>: LiDAR, Moths, Biodiversity, Bioindicators Taxa, Landsat, NDVI</p><p><i>Forest@ 14 (1): 84-93 (2017)</i> - doi: 10.3832/efor2293-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Infusino M, Scalercio S, Corona P, Greco S, Puletti N, Chianucci F Articoli Scientifici 2017-02-27 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

Recent advancements in informatics and communication technologies have led to an increasing employment of analytical and communication tools in forestry, including data from satellite, airborne, unmanned aerial vehichles, global positioning systems, and many sensors, devices and other geospatial tools. Precision forestry enables highly repeatable measurements, actions and processes to manage and harvest forest stands, simultaneously allowing information linkages between production and wood supply chain, involving resource managers and environmental community; all these factors are contributing to the wider goal of sustainable forest management. In this report, we review the most recent advances in the precision forestry applications and tools, with particular reference on advanced forest inventory, decision support systems, precision forest harvesting, and wood traceability.

Natura 2000 is an ecological network of protected areas identified by the Habitats Directive (92/43/EEC) and the Birds Directive (79/409/EC) - recently replaced by the Directive 2009/147/EC - in order to ensure the long-term protection of endangered species in their natural habitats in European Union (EU) territory. EU Member States are responsible for developing and implementing the procedures defined by Habitats Directive, but there are no specific recommendations about participation of stakeholders and local community in the decision-making process. Consequently, each country has adopted a different participatory strategy taking into account the principles of integration approach. The integration approach is based on combining human activities and nature conservation purposes in the same area or, at least, in areas in close proximity. In Italy, the implementation of Natura 2000 network was developed at local level (Regions and Autonomous Provinces) using different approaches and procedures. Starting from these considerations, the aim of the study was to analyse the stakeholders’ involvement process during the implementation of Habitats Directive in Italy and the management of Natura 2000 sites. This study was realized using three main criteria with the respective indicators: (1) inclusiveness of participatory process; (2) democracy of participatory process; (3) cooperation and conflicts during the implementation process of Natura 2000 network. The data were collected through the administration by email of a semi-structured questionnaire to 56 stakeholders divided in four main groups of interest (public administrations, universities and research centres, environmental associations, private organizations). The results of the survey show that the participatory process was characterized by a low level of inclusiveness despite the existence of some best practices at local level. In many cases, the decisions were taken by a low number of stakeholders - mostly public administrations - while the individuals of local community were only informed. Conversely, the results highlights as positive aspect the increasing level of trust among stakeholders after the Natura 2000 network implementation process.</p><p><b>Keywords</b>: Habitats Directive, Protected Areas, Nature Conservation, Participatory Process, Conflicts, Stakeholders</p><p><i>Forest@ 14 (1): 13-27 (2017)</i> - doi: 10.3832/efor2131-014<br/><a href="" target="_blank"></a></p><hr size="1"/> Paletto A, Graziani A, Brescancin F, De Meo I Articoli Scientifici 2017-01-31 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

In this study, we focused on the impact of Acacia saligna, an Australian invasive plant species, on the coastal ecosystem’s ecology and biodiversity along the sandy coasts of Molise (southern Italy). We analyzed data from 61 vegetation plots recorded in coastal pine forest and Mediterranean scrub habitats of Molise throughout the preparatory actions of the “LIFE Maestrale” project (NAT/IT/000262). In order to study the ecological impact of Acacia saligna comparing invaded and non-invaded areas, we first assigned the Ellenberg’s indicator values to each plant species, which were then used to relate the presence of Acacia saligna with ecological characteristics of sites through a generalized linear model (GLM). Our results showed a significant positive relationship between the presence of Acacia saligna and high levels of soil nutrients and, on the contrary, a negative relationship with the presence of mesophilic species, which are typical of the community interest habitats of pine forest (2270*). The use of ecological indicators is effective to pinpoint the ecological effects of biological invasions, as well as to evaluate habitat conservation state and to identify vulnerable native species.</p><p><b>Keywords</b>: Alien Species, Acacia Saligna, EC Priority Habitat, Nitrophilous Species, Molise</p><p><i>Forest@ 14 (1): 28-33 (2017)</i> - doi: 10.3832/efor2211-013<br/><a href="" target="_blank"></a></p><hr size="1"/> Calabrese V, Frate L, Iannotta F, Prisco I, Stanisci A Articoli Scientifici 2017-01-31 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

However, the landscape has a symbolic value because it can be considered the identity and culture of a territory that includes the values and beliefs of local population. The Alpine landscape is a unicum in the world due to its geomorphologic, climatic and vegetation characteristics and socio-economic conditions of local population. Over the centuries the social perception of Alps has changed: in a first phase the Alps were considered “horrible and scary mountains”, later Alps were perceived as “beautiful and fascinating places”, and currently the Alpine mountains are considered a place of relaxation and recreation. The analysis of landscape perception aimed to investigate the visitors’ opinions about landscape is an important instrument to support the decision concerning the land planning and management. This study focuses on the analysis of the aesthetic perception of visitors on Alpine landscapes following two perspectives: a first overall perspective considering the landscape as a mosaic of different land uses and a second perspective of detail observing the individual components that characterize the forest landscape. The aim of the study is to identify the most appreciated elements of landscape from the aesthetic point of view and the influence of socio-demographic characteristics of respondents on individual perception. In order to investigate the perception about the Alpine landscapes 358 visitors of two sites of Trentino-Alto Adige (Val di Genova and Santa Maria lake) were interviewed using a structured questionnaire. The results show that the most appreciated elements of the landscape by the visitors are water (lakes and rivers) and forests. These preferences are also conditioned by the site where the interviews were made. In addition, the results show that for the respondents of this survey the forest with the highest attractiveness is an uneven aged and mixed forest with randomly distributed trees, a canopy cover between 50% and 60% and without lying deadwood. Finally, this study shows the influence of socio-demographic characteristics of respondents (age, gender and origin) on individual preferences considering three types of perceptions: instinctive perception, affective perception and intellectual perception.</p><p><b>Keywords</b>: Cultural Landscape, Forest Multifunctionality, Visitors, Recreational Forest Function, Italian Alps</p><p><i>Forest@ 13 (1): 73-89 (2016)</i> - doi: 10.3832/efor2119-013<br/><a href="" target="_blank"></a></p><hr size="1"/> Pastorella F, Santoni S, Notaro S, Paletto A Articoli Scientifici 2016-12-03 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

Brown was observed. The main symptoms on both young and adults plants consisted of elongated cankers on the trunks and epicormic shoots, wilt of the canopy and dieback interested mostly aged trees. The woody tissues showed browning beyond the cankers. Sapwood and heartwood appeared decayed with a brown to gray-greenish discoloration. One fungal species was consistently isolated from infected woody tissues, which was morphologically attributed to Neofusiccocum sp. The sequencing of the ITS regions of a representative isolate allowed to identify (99% similarity) the species Neofusiccocum parvum (Pennycook & Samuels) Crous, Slippers and Phillips, teleomorph Botryosphaeria parva Pennycook & Samuels. The pathogenicity tests have reproduced symptoms similar to those observed in the field. N. parvum is the aetiologic agent of mortality of australian blackwood observed in Sicily and to our knowledge this is the first report of this fungus on Acacia melanoxylon. It is a generalist pathogen, cosmopolitan, present in many temperate areas, Mediterranean and subtropical. The older Peloritani Mountains populations of australian blackwood seem particularly susceptible to the pathogen, the latter favored by the lack of silvicultural interventions that generate interspecific and intraspecific competition, as well as the increase and spread of the fungus. To minimize the consequential damage is necessary to adopt sanitation measures that would lower the fungal inoculum and program substitutions of this exotic species with others that have multiple functions suited to environments (e.g., Chestnut) or encouraging the establishment and development of native species, such as the holm oak and shrub.</p><p><b>Keywords</b>: Australian Blackwood, Cankers, Botryosphaeriaceae, Italy, Sapwood</p><p><i>Forest@ 13 (1): 41-46 (2016)</i> - doi: 10.3832/efor2041-013<br/><a href="" target="_blank"></a></p><hr size="1"/> Sidoti A Articoli Scientifici 2016-10-14 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

There is an information gap in the Italian literature with regards to private forest ownership, while several analysis are available on the characteristics and the management systems of public forest ownership. To address this gap, this paper presents the characteristics of private forest owners and their evolution in time by reviewing the international literature in the last three decades. The examined studies are reported according to four perspectives: (i) the available classifications and/or typologies of private forest owners; (ii) the determinants of different forest owners’ behaviors, especially in relation to their objectives; (iii) the attitudes of forest owners and the motivations behind their management decisions; (iv) the valuation of the willingness to accept monetary compensations in return for the provision of ecosystem services. The results show a very complex picture, varying both in space and time. However, some recurring features can be identified: (i) not only are forest owners motivated by timber production goals, but also by other reasons, often very diversified and detached from market considerations; (ii) a “multi-functional” forest owner is by no means less active, but, conversely, is more active than a forest owner whose sole objective is timber production; (iii) in general, the active owner is a farmer whose family has owned the forest for many generations (and in this case he/she is more market-oriented), or is a new entry in the forestry sector; (iv) the “passive” owner is usually elderly, non-farmer and resides far from the property. In addition, the “absent” owner is a common problem to several of the examined geographical contexts. Although the results of the review cannot be transferred as such, they represent a useful starting point for similar analyses in the Italian context. Examining the determinants and attitudes of private forest owners in Italy would indeed prove interesting, given that private forest ownership in Italy represents a relevant share of total forest area and that the implementation of new policy tools such as payments for ecosystem services requires active participation by all key actors, including forest owners.</p><p><b>Keywords</b>: Private Forest Ownership, Forest Owners, Attitudes, Forest Owners’, Typologies, Ecosystem Services</p><p><i>Forest@ 13 (1): 18-30 (2016)</i> - doi: 10.3832/efor1751-013<br/><a href="" target="_blank"></a></p><hr size="1"/> Mozzato D, Gatto P Rassegne 2016-04-04 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

The Final motion of the Round table “The forest and man”, held in Florence in 1995, stated that “The forest is a complex biological system which has a fundamental role in maintaining life on our planet. Like all living systems, the forest has intrinsic value, it is a subject of rights which must be preserved and protected”. In the last decades a new forestry culture has developed which is based on three “E”s: Ecology, Economy and Ethics. Silviculture is a biological science and its vitality depends on its history and its ability to confront, not only on technical bases but also in scientific terms, the challenges coming from constant change. It is concluded that radical innovation is an asset of young people. They are the ones in charge of future scientific development. For this reason they must be educated to creativity and cultural independence. They must be aware of the importance of their work, which should be based on intense study and a search for excellence, even if this brings no immediate acknowledgement. If young researchers follow these rules, nothing will be precluded and success will finally arrive.</p><p><b>Keywords</b>: SISEF National Congress, Ecology, Economy, Ethics</p><p><i>Forest@ 12 (1): 45-46 (2015)</i> - doi: 10.3832/efor0087-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Ciancio O Commenti & Prospettive 2015-10-24 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

Its range partly overlaps with that of European ash (Fraxinus excelsior) and interspecific cross is possible. These habitats are of the utmost importance due to their high level of biodiversity, but highly threatened by human activities. Since climate change is expected to favor the diffusion of narrow leaved ash, a study was carried out with the aim of enhancing our knowledge of the biological, ecological and genetic aspects of this species. Twelve populations of narrow leaved ash from north-eastern Italy were sampled and their genetic variability was analyzed by means of six molecular markers (nuclear microsatellites), of which 4 gave consistent and repeatable results. Overall, 113 alleles were observed, of which 38 were present in only one population (private alleles). Consistent levels of genetic variability was found (mean number of alleles per locus = 7.08, effective number of alleles per locus = 4.37, expected heterozygosity = 0.613), though lower than those reported in the literature. Fixation index was very close to zero, indicating a good agreement with Hardy-Weinberg’s expectations. The genetic differentiation among populations was significant (both GST e FST as high as 0.102), although it was not possible to correlate the distribution of genetic variability with ecological or geographical factors. Genetic pools of F. excelsior and F. angustifolia were distinct, though several individuals showed intermediate genetic characteristics, especially in the population from Grotta di Farra where both species are present and many individuals showed intermediate morphological features. The presence of individuals possibly originated by interspecific cross should be taken into account in the case of seed collection. Our results may contribute to a rationale management of genetic resources of narrow leaved ash, also considering the current legislation on forest reproductive material.</p><p><b>Keywords</b>: Narrow Leaved Ash, nSSR Markers, Genetic Variability, Genetic Differentiation, Interspecific Hybridization, Regions of Provenance, Seed Stands</p><p><i>Forest@ 12 (1): 25-40 (2015)</i> - doi: 10.3832/efor1628-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Belletti P, Camerano P, Ferrazzini D, Fiorentin R, Cego Pernigotto F Articoli Scientifici 2015-08-08 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

In Italy, the new National Energy Strategy established that the renewable energy must cover 20% of gross energy demand by 2020. In order to achieve this objective the forest biomass could be of fundamental importance. In this context of increasing extraction of wood residues from forests, it is relevant to analyse two key aspects: (1) the involvement of stakeholders in the strategy for the valorization of forest-wood-energy chain at local level; and (2) the potential impacts of increased forest biomass extraction on environment. This paper analyses these two aspects through the stakeholders’ opinions in a case study in the Alto Adige (Sarentino valley). Stakeholders’ opinions concerning the analysis of SWOT categories (strengths, weaknesses, opportunities, threats) of the bioenergy supply chain were investigated using the SWOT-AHP (Analytical Hierarchy Process) approach. The results show that the local stakeholders emphasize some strengths (e.g., additional income over time for private forest owners) and opportunities (e.g., development of shared forest management strategies among small forest owners) of forest-wood-energy chain, and consider less relevant the weaknesses and threats. The results concerning one of most important potential threats - impacts on environment - show that all groups of stakeholders (public administrations, associations and NGO, research bodies and universities, and actors of rural sector) consider positive the impacts of increased forest biomass extraction on recreational activities and negative on other three ecosystem services (carbon sequestration, hydrogeological protection, and biodiversity).</p><p><b>Keywords</b>: Forest-wood-energy Chain, Forest Biomass, Stakeholders, SWOT Analysis, AHP (Analytical Hierarchy Process), Val Sarentino (Alto Adige</p><p><i>Forest@ 12 (1): 1-15 (2015)</i> - doi: 10.3832/efor1536-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Nikodinoska N, Mattivi M, Notaro S, Paletto A, Sparapani G Articoli Scientifici 2015-06-20 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

Norway spruce plantations located in the Foresta Demaniale Alta Val Parma (Corniglio, province of Parma - Italy) experienced since 2004 a massive outbreak of Norway spruce bark beetle (Ips typographus). This outbreak has been triggered by the exceptionally warm and dry summer of 2003. In the following years bark beetle attacks repeated and spread, raising concern about the future of this kind of stands. A survey program has been carried out to help local administration to chose the correct managements strategies. Monitoring of Ips typographus population, carried out between 2007 and 2013, confirmed the presence of two generations per year, with values above the risk threshold in 2007 and just below though very high in 2011. In the affected area, six survey plots have been realized to test different management options with the aim of favoring a fast regeneration of the forest cover. The tested options showed the great difficulty in the establishment of natural generation either for the lack of mother plants in such pure stands or for competition with tall grasses. Sowing brought no significative results, while direct plantation of indigenous broadleaves was more effective, with almost half of the individuals still alive after three years. Our results confirm the great difficulty to rebuild the forest cover after strong ecological disturbances in these artificial forests. Hybrid management strategies and ad hoc silvicultural choices seem to be the only way to manage such kind of situations in a National park, where the priority is biodiversity conservation.</p><p><b>Keywords</b>: Bark Beetle, Norway Spruce, Disturbance, Natural Regeneration, Management Choices</p><p><i>Forest@ 12 (1): 16-24 (2015)</i> - doi: 10.3832/efor1539-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Vignali G, Barbarotti S, Piovani P, Maresi G, Salvadori C Articoli Scientifici 2015-06-20 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.

B. nigrifluens may compromise wood quality and, in some cases, impair plant survival due to extensive cankers and bark necroses. Bacterial isolates obtained from bark tissue fragments, typed by rep-PCR analysis after multiplication on proper selective growing media, confirmed the diagnosis of the causal agent, despite the presence of other bacterial species. B. nigrifluens was detected in 28% of common walnut arboricultural stands located in Piedmont plains and hills, especially those located in the Vercelli province and in some areas of the Alessandria province. Based on the results of the cluster analysis carried out on PCR amplicons, none of the other bacterial isolates showed any genotypic similarity with the related B. rubrifaciens, the agent of the deep bark canker of walnut, which has not been detected in Europe yet. The application of the three rep-PCR variants, including BOX-PCR applied for the first time to B. nigrifluens, gave similar results, but with different cluster structures. In two pilot plantations, trees already presenting necroses did not necessarily develop new necroses or enlarge the pre-existing cankers in the following years. The disease apparently does not spread according to a climate factor, whereas it may be affected by plant genotype that possibly promotes the transition of B. nigrifluens, probably already present in tissues in an asymptomatic endophytic phase, to the pathogenic phase.</p><p><b>Keywords</b>: English Walnut, Brenneria nigrifluens, Shallow Bark Canker, Rep-PCR, Wood Arboriculture</p><p><i>Forest@ 11 (4): 180-188 (2014)</i> - doi: 10.3832/efor1335-011<br/><a href="" target="_blank"></a></p><hr size="1"/> Giorcelli A, Gennaro M Articoli Scientifici 2014-11-20 Copyright (c) 2017, Italian Society of Silviculture an Forest Ecology.
