The encyclical letter Laudato si’ of the Holy Father Francis on care for our common home, our planet, is considered. The approach to complex socioecological systems is stressed. In this same perspective, the tenth congress of the Italian Society of Silviculture and Forest Ecology, to be held in Firenze (Italy) next September 15th to 18th, aims to highlight the role of forests and forestry in supporting the life on the planet. Forestry can be one of the most dynamic sectors of the “green economy”. The ethical norm of respect for the intrinsic value of the ecosystem is just brought about by concern, closeness and familiarity between man and forest and, on the contrary, it may be hampered by aprioristic resource immobilization.</p><p><b>Keywords</b>: Encyclical Letter, Forestry, Land Ethic, Tenth Congress of The Italian Society of Silviculture and Forest Ecology</p><p><i>Forest@ 0 (0): 233-234 ()</i> - doi: 10.3832/efor0088-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Corona P Editoriali 2015-08-25 Copyright (c) 2015, 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@ 0 (0): 217-232 ()</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) 2015, 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@ 0 (0): 193-207 ()</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) 2015, 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@ 0 (0): 208-216 ()</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) 2015, Italian Society of Silviculture an Forest Ecology.
