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="http://www.sisef.it/forest@/contents/?id=efor1536-012" target="_blank">http://www.sisef.it/forest@/contents/?id=efor1536-012</a></p><hr size="1"/> Nikodinoska N, Mattivi M, Notaro S, Paletto A, Sparapani G Articoli Scientifici 2015-06-20 http://www.sisef.it/forest@/contents/?id=efor1536-012 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="http://www.sisef.it/forest@/contents/?id=efor1539-012" target="_blank">http://www.sisef.it/forest@/contents/?id=efor1539-012</a></p><hr size="1"/> Vignali G, Barbarotti S, Piovani P, Maresi G, Salvadori C Articoli Scientifici 2015-06-20 http://www.sisef.it/forest@/contents/?id=efor1539-012 Copyright (c) 2015, Italian Society of Silviculture an Forest Ecology.
