In the early 7 th century, numerous large trees in the Sila were felled at the behest of Pope Gregory I. Each trunk was cut into a beam, which was then taken down to the Tyrrhenian coast and shipped to Rome to be used in the construction of St. Peter’s Basilica. At the end of the 10 th century, the trees to be felled in a private wood, located on the Amalfi Coast of the Sorrento Peninsula, were selected and identified. These actions were carried out in close conjunction with the owners of a shipyard, of the forestry enterprise chosen to perform the felling and subsequent operations, and of the lady owner of the woodland being felled, each of whom was able to act in his/her own best interests. Lastly, in the first half of the 13 th century, Emperor Frederick II of Hohenstaufen’s woodcutters and carpenters were unable to locate numerous large trees in the montane forests of Basilicata, whose trunks would have been used as beams for the roof of Lagopesole Castle. The study ends with some final remarks on the silvicultural methods attributed to the different forest fellings examined.","PeriodicalId":336087,"journal":{"name":"L'italia Forestale E Montana","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129631527","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 ownership of statistical investigations on forests have belonged for a long time to ISTAT, which is part of the National Statistical System. In time, other surveyors have been added to the system and, as a consequence, some investigations have been suspended or merged. The investigation concerning the logged area and the quantity of wood was one of the most important forestry statistics. It was made on a regional basis but, being based on administrative data, its accuracy has decreased because of different problems such as the undervaluation of logging and the decline of the response rate.

Coastal stone pine forests provide many goods and services, such as dune stability, protection of arable lands, biodiversity, wildlife habitat, space for tourism and recreation, landscape perception and aesthetic, wood and non-wood forest products. Since the middle of the 20th century this anthropogenic landscape has been diminishing due to changes in forest dynamics and land use. Nowadays, the quality and quantity of goods and services provided by coastal pinewoods are influenced by the adopted management styles and by decision-making factors which depend on temporary socio-economic needs that often veer from sustainable forest management criteria. The objectives of this study were: (i) to map the current distribution of stone pine forests along the Tuscan coast, (ii) to analyze land use and land cover changes between 1954 and 2010, and (iii) to describe the structure and principal dynamics of stone pine forests in this area. Results show that in 2010, stone pine forests amounted to 10 660 ha. Land use changes along the Tuscan coast reflect the trends reported on a national scale: urbanization, abandonment of agricultural areas, and expansion of forested areas. Pure stone pine forests have contracted between 1954 and 2010 while the frequency of mixed stone pine-broadleaf forests has grown as a result of successional dynamics, which have progressively led to a transformation of the coastal landscape. Results are discussed with the intention of providing knowledge to support management of the forest landscape along the Tyrrhenian coast","PeriodicalId":336087,"journal":{"name":"L'italia Forestale E Montana","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133976220","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 habitat suitability maps were constructed by the land suitability method of FAO using climatic parameters (temperature and precipitation) and physical parameters (slope of the land and soil characteristics). The climate change scenario used is the A2 scenario of HadCM3 model. The predictive ability of cartographic models was evaluated with ROC statistical analysis. The accuracy of the habitat suitability maps was good (AUC = 0.875 for chestnut, and 0.813 for black pine), especially for beech (AUC = 0.952); for the turkey oak, the quality of the cartographic model was lower (AUC = 0.628) than the other species. The results indicate the presence of critical environmental issues for about 20% of the total area of pine forests (10,071 ha), a proportion that rises to 50% in the climate change scenario considered.

The Vallombrosan Benedictine congregation was founded by Giovanni Gualberto in the 11 th century. Starting from the 14 th century the monks developed the silvicultural technique of clear felling and replanting silver fir. In 1866 the Vallombrosa Forest was transferred to the Italian State and the first Italian Forestry School was founded there in 1867. The State administration continued with the management model applied by the monks; the fir stands increased from 217 ha in 1878 to 680 ha in 1960. The management approach changed in 2006 when a new Forest management plan was drawn out which does not try to impose an optimal and predefined structure and composition on the forest but aims at favoring a gradual evolution towards more diversified systems, in terms of composition, structure, habitats and processes. On a small area around the Vallombrosa Abbey the plan has created a Silvomuseum where fir stands will be maintained by the traditional silvicultural treatment developed by the monks. In 2013 and 2015 very severe wind storms hit the forest creating extensive windbreaks in the fir stands. Because of various administrative reasons the 2006 Plan has been applied only on a very limited area, and so it has not been possible to verify if the new management approach has increased resistance and resilience of the fir stands to these extreme events. This points out the need for an active management of the forest because only the constant and informed action of the silviculturist can guarantee the conservation of this precious cultural and environmental asset.","PeriodicalId":336087,"journal":{"name":"L'italia Forestale E Montana","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121237869","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 ecological marginality of these forests is particularly evident in the fragmented and isolated beech stands, near the timberline and/or located on less favourable topographic conditions. In this study we analyzed stand-structural parameters and tree health comparing recently coppice felled beech stands and control plots. Additionally, these aspects have been related also to the local topographic gradient and the cover fragmentation. Results clearly show a pronounced tree health reduction (more crown and bark damages, higher percentage of dead trees, lower seedling density) related to cut coppice, as far as to marginal topographic condition (on ridges and slopes) and stand-cover fragmentation (in clearing/border trees). The clear decreased tree health may lays an increasing future threat for these multi-marginal (for latitude, topography and cover fragmentation) beech stands. In addition, our results could also support the hypothesis that, although the silviculture effects originated by the human actions is quite evident in the two compared groups (coppice-cut and control), hastening the tree health reduction, a general climate change effect is going on these marginal beech stands. The reduced tree health status also in control plots seems to show this way.","PeriodicalId":336087,"journal":{"name":"L'italia Forestale E Montana","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132183561","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}

Stand structure was analyzed using structural indexes with data collected in plots drawn out in beech stands along the timberline. Diameter growth was measured on a sample of trees felled by natural disturbances. During 2013, a good mast year, we analyzed seed production of these stands and germination rate in comparison to seed collected from stands growing at lower altitudes. Results showed that there are two main structural types which are still strongly impacted by grazing: single storied stands with big and very old trees (over 400 years, DBH>70 cm); and stands with complex structures where groups of old trees are mingled with multistoried patches formed by trees of different size and age. In all cases, dendrochronological analyses showed very slow diameter growth. Void seed percentage at the timberline was 82%, much higher than the one for seeds produced at lower altitudes (55%). Nevertheless, seed production in good years can be considered sufficient if compared to other Italian beech stands. We believe our study can be a useful starting point for a deeper and coordinated study on forest stand dynamics at the timberline, an area which is particularly delicate because very susceptible both to environmental and land use changes.","PeriodicalId":336087,"journal":{"name":"L'italia Forestale E Montana","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121362820","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}

We measured height and deer impact on all firs planted in various sized clusters (from 6 to 59 fir per cluster, distance between firs in the cluster: 15-20 cm). Six years after planting, almost all the young fir were impacted by deer and often showed deviated stem growth as a result of past browsing. The majority of the silver fir saplings were less than one meter high, and were significantly smaller than firs planted inside a fenced control area. Plant position inside the cluster did not affect stem height and number of deer impacts. Height and impact incidenc ewas instead related to fir density within each cluster.
