The aim of this study is to develop a set of eco-innovation indicators suitable to analyze the forest-wood chain at local level. The study was structured in three steps: literature review on eco-innovation indicators; defining a set of eco-innovation indicators suitable for the forestry sector; testing of eco-innovation indicators in a pilot area (Province of Trento, Italy). Eight indicators and sixteen sub-indicators suitable for the forestry sector were identified. The eco-innovation indicators were quantified using official statistics and new data collected by administering a questionnaire to 114 forest-wood chain actors. The results show an average efficiency of the timber processing and a medium-high level of enhancement of the wood residues generated by production process. Conversely, the level of collaboration between actors of forest-wood chain and institutional actors (universities, research institutes, R&D agencies) could be improved with the aim of increasing the diffusion of eco-innovation knowledge and information. The eco-innovation indicators developed by this study emphasize environmental impacts and negative externalities of innovation process in the forestry sector.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66120968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of these reforestations are characterized by a high instability, vulnerability, and a limited resistance to atmospheric agents. In this situation, it is crucial to define silvicultural interventions able to increase the ecological stability of black pine stands and at the same time to guarantee the economic sustainability of the wood products obtained. Thinning in black pine forests can provide wood material for energy use. The main aim of the present study was to investigate the economic sustainability of a local wood-energy supply chain applying three different forest management options. The case study was Monte Morello forest, a degraded black pine forest located in Central Italy. The results show that the long-term economic sustainability of the wood-energy supply chain is ensured only when the use of bio-fuel is characterized by high energy efficiency. In addition, the results show that public contributions are fundamental to ensure that silvicultural interventions are realized with a positive economic balance and that to surmount this situation many loggings companies are organizing. Finally, the results highlighted the importance of the quantities of thermal energy sold to ensure the economic and environmental efficiency of the wood-energy supply chain.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48925570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

F. a commercially and ecologically important forestry species of south Asia, is facing serious regeneration problem since last century. The continuously diminishing natural regeneration is associated with numerous abiotic and biotic factors, like edaphic, micro-climatic, physiological, genetic, anthropogenic, pathogens, insect-pests, etc. Following a good seed year and timely commencement of monsoon, Sal seeds germinate readily, and thousands of seedlings cover the forest floor. Subsequently, these get afflicted with die-back syndrome impeding shoot growth. Regular fire incidences during hot and dry season further aggravates the problem. Among biotic factors, Hoplocerambyx spinicornis , Cylindrocladium floridanum and Inonotus shoreae causes severe heartwood decay, blight and dieback leading to mortality. Moreover, over-exploitation, illegal felling, grazing, etc., have severely depleted the Sal forest. This review systematically explores the factors contributing to regeneration problem in S. robusta and opines appropriate silvicultural operations and management strategies for the conservation of Sal forests through SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis. We emphasized on the ecological aspects, soil characteristics, micro-climatic factors and importance of associated species to develop sustainable management regimes. Highlighting all facets of Sal regeneration problem and SWOT assessment, we suggest comprehensive weaknesses and threat perceptions to formulate strategies to seal the gaps.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45832511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As direct measurements are impractical, indirect optical methods have often been used to estimate CC from the complement of gap fraction measurements obtained with restricted-view sensors. In this short note we evaluated the influence of the image pixel resolution (ground sampling distance; GSD) on CC estimation in poplar plantations obtained from field (cover photography; GSD < 1 cm), unmanned aerial (UAV; GSD <10 cm) and satellite (Sentinel-2; GSD = 10 m) imagery. The trial was conducted in poplar tree plantations in Northern Italy, with varying age and canopy cover. Results indicated that the coarser resolution available from satellite data is suitable to obtain estimates of canopy cover, as compared with field measurements obtained from cover photography; therefore, S2 isrecommended for larger scale monitoring and routine assessment of canopy cover in poplar plantations. The higher resolution of UAV compared with Sentinel-2 allows finer assessment of canopy structure, which could also be used for calibrating metrics obtained from coarser-scale remote sensing products, avoiding the need of ground measurements.","PeriodicalId":37733,"journal":{"name":"Annals of Silvicultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46649427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the species diversity in the primary forest was not significantly different from the seven-year disturbed forest while the five-year disturbed forest was significantly different from the two types mentioned earlier. Moreover, the similarity index showed that the primary and seven-year disturbed forest were identical and both were different from the five-year disturbed forest. In addition, eight life forms were enumerated, viz. bamboo, climber, fern, herb, rattan, shrub, small tree, and large tree in which they were dynamic during the post-disturbance compared to primary forest.

The study of tree-rings time series through exploratory methods may also take advantages, by allowing some interpretation to be further checked via a small number of statistical tests. In particular, while providing overall results close to those of PCA, HFC complements it, by providing a classification of the time-series and estimating a representative chronology for each group, common to the clustered ones. As case study, a data set is taken from literature, composed by five synchronous 79 years-long chronologies of Pinus pinea L., from five different populations scattered along the Tyrrhenian coast in peninsular Italy.
