The Southeastern Europe, which is usually known as Balkan Peninsula, harbours a vast number of plant species among which a great number of relict and endemic ones. This region was one of the main areas in Europe where plant species found shelter in refugia and survived during the last glaciation. These refugia were the source areas for the postglacial colonization of many forest tree species. Human impact has been reported in the region since antiquity resulting in fragmentation of forests and deforestation. Marginal/peripheral (MaP) populations could be identified for most of the forest tree species occurring in the region. However, detailed information about MaP populations is restricted to few cases. Most of the MaP populations identified by FP1202 experts are not located in protected areas. Thus, approximately 27 % of the MaP populations are included in Natura 2000 sites, and only one out of the four reported populations is included in a genetic conservation unit. Many MaP populations (40%) are registered as seed stands and only 14% are included in EUFGIS database. Conservation of forest genetic resources, including MaP populations, is a component of sustainable management of forests in many countries of the region.

Evaluating tree roots systems without compromise their environment with destructive and laborious methods, is of crucial importance for preserving plant resources. Ground Penetrating Radar (GPR) technology applied to root and forest ecology studies is a key active remote sensing technology, based on the use of electromagnetic waves, providing unique, non-invasive resources to sample root biomass and spatial distribution. This paper reviews the use of GPR techniques, as near surface sensor radar scanning technology using a ground-coupled single-offset antenna configuration, to yield accurate tree roots system information. Based on the analysis of both geometric and general characteristics of underground soil layers, the GPR can be used as a rapid and high-spatial resolution tool for the analysis of roots distribution, morphology, orientation, and the occupied soil volume. Finally, this paper will show the opportunity of applying modern technologies of remote detection of active sensors in terms of application of radar technology to tree root systems.

In Italy, in the last decade, there have been both new social requests and an ever-increasing sensitivity towards the multiplicity of values attributed to forests. This has led to a profound revision of the structure of forest planning. This paper illustrates the planning system, characterised by a hierarchical approach, focusing on the upper level, that is Forest Landscape Management Plan (FLMP). At this level of planning, attention to the different needs and targets expressed by the population is considered of strategic importance and thus requires a participative attitude. In the first part of the paper the authors show the approach currently used in forest landscape planning, through a case study carried out in a rural area of the Appennine mountains, focusing in particular on the method established for the process of participation. In the second part, the quality of participation in the case study is analysed, after describing the methodology followed in order to identify a set of criteria for success, deemed particularly relevant

Carrying capacity is one of the most important variables that should be assessed for a proper evaluation of forage potentiality of pastures. Nevertheless, inside forest management plans, reduced costs make impossible the involvement of additional technical staff specialized in this domain and for this reason different methodologies to simplify data collection were proposed for pasture planning. In this paper a simplified method to evaluate the pastoral value (one of the most common procedure for carrying capacity estimation) is proposed and assessed in real conditions in order to obtain a proper potential stocking rate of a whole pasture area. The method is based on a previous research that proposed a simplified method of data collection that is performed by means of different functional groups of species or botanical families: palatable grasses, not palatable grasses, legumes, species belonging to other botanical families, spiny and poisonous species, trees and shrubs. Each category is linked to its feeding behavior by an index that summarizes forage potentiality and this permits to classify the resources in different quality classes, each of them characterized by a given potential stocking rate. The proposed methodology seems easy to be performed also by staff without a specific formation in pasture management and comparison performed with the traditional procedure produced accurate results. Even if the proposed scheme should not to be considered alternative to the original methodology, it can be useful to acquire information for pastoral resource management, especially at territorial level.

Brutia pine is a Mediterranean tree species of high ecological value, widely planted for soil protection, windbreaks and timber, both in its native area and elsewhere in the Mediterranean region. However, there is not yet enough information relating its growth dynamics and yield. The aim of this study was to evaluate the volume of Pinus brutia in a planted peri-urban forest (reforested area) in Greece. A single-entry, individual tree volume model has been developed using data from 18 permanent experimental plots, in the context of a research project regarding recovery of degraded coniferous forests.

Precision forestry is a new direction for better forest management. Precision forestry employs information technology and analytical tools to support economic, environmental and sustainable decision; the use of geospatial information tools enables highly repeatable measurements, actions and processes to manage and harvest forest stands, simultaneously allowing information linkages between production and wood supply chain, including resource managers and environmental community. In this report, we reviewed the most recent advances in the use of geospatial information technologies in forestry, and discussed their potential opportunities and challenges towards forest management and planning in the framework of precision forestry.

This paper quantified the impact of urban expansion on landscape characteristics of a famous landscape icon, the Roman Campagna, during the last thirty years. Landscape composition and structure were assessed between 1974, when the distinguishing features of Roman Campagna are still widespread and 2008, after the trajectory of urban decentralisation and urban sprawl. Changes in landscape structure were explored by spatial pattern analysis to detect how structural changes in landscape components can modify both land structure and landscape image. Non-parametric correlation statistics and multi factor analysis showed that the distinctive features of the Roman Campagna landscape are now blurred. A generalized landscape mixite was generated by the juxtaposition of different fragmented land uses, as showed by a negative relationship between changes in surface area and patchiness found in almost all other land use classes. Adaptation measures for preserving peri-urban agriculture in a landscape changed in structure and image are finally discussed.

Fire represents an important natural feature of Brazilian landscape, especially in the Cerrado biome. The Cerrado is the economic livelihood of thousands of people from rural areas in Brazil. It is one of the most important hotspot of biodiversity in the world but also it is a fire-prone area thanks to the high flammability index of the vegetation. Residents and native people of this environment use fire very frequently. The majority of wildfires are caused by humans, though there are some aggravating natural factors affecting the risk, intensity and severity of wildfires. Since residents are continuously involved in fire suppression activities, understanding their perceptions is important for the decision makers who must assess the local capacity to preserve natural resources. This study explores perceptions about wildfire risk and fire mitigation behaviors within three municipalities of the state of Tocantins (Brazil). The study demonstrates that survey participants perceived wildfire risk as rather high, although the perceptions were complex and conflicting among interviewees. A wide range of confused perceptions about fire ignition and heterogeneous point of view have carried out form the survey. However, the residence of interviewees and their educational attainment result the variables that significantly (p-value <0.05) affect the inhabitants’ perceptions.

In young black pine plantations, the most valuable and interesting thinning scheme is mainly based on the positive selection of dominant and well-shaped trees to be candidates for carbon sequestration, timber production and natural regeneration. The mechanical stability of candidate trees is here a fundamental skill that must be taken into account and the slenderness ratio (HD) is one of the main indicators. HD has been recently proved to be correlated to the living whorl number (LWN) by Cantiani & Chiavetta (2015). In this study, the statistical model was re-calibrated in order to study the influence of soil fertility on the HD - Living whorls number (LWN) relationship. The fertility-balanced models estimated a different LWN threshold. The model for the highest fertility class (Site index 24) estimated 12 LWN (RMSE of 20%). Similarly, a lower value were detected for the other two fertility classes, SI20 and SI16, where 10 LWN were considered enough with an associated RMSE of 16% and 17% respectively. Compared to the general model provided by Cantiani & Chiavetta (11 LWN with 18% of RMSE) the site index approach improved the accuracy and reliability.

This research note aims to exemplify the potential of annual time series of wildfire geodatasets to quantify fire occurrence and recurrence amongst different woodland types at large scale, under an international forestry perspective. The study covers a time series of areas affected by wildfire between 2007 and 2014 in Italy. A GIS operation of geometric intersection was carried out between burned areas geodataset time series and Corine Land Cover. Mediterranean pine forest, high maquis, transitional woodland-shrub and high oro-Mediterranean pine forest are the woodland types most preferred in terms of fire occurrence and recurrence. Large fires and megafires hold a significant share of total burned area. An unexpected finding is the huge impact of fires in wildland-urban-interface areas. The proposed analysis provides spatial information that is central to any approach to fire management at large scale. Research findings provide support that can be used e.g. for advancements in research, prioritization of fire prevention, suppression measures, economic incentive allocation, and urban and peri-urban planning.
本研究报告旨在举例说明，在国际林业视角下，野火地理数据集的年度时间序列在大尺度上量化不同林地类型的火灾发生和复发的潜力。该研究涵盖了意大利2007年至2014年间受野火影响的一系列地区。将燃烧区地理数据集时间序列与Corine Land Cover进行几何相交的GIS操作。地中海松林、高马丘林、过渡林地-灌丛和高山麓-地中海松林是火灾发生和复发的首选林地类型。大火和特大火灾占总燃烧面积的很大一部分。一个意想不到的发现是火灾对荒地和城市交界地区的巨大影响。提出的分析提供了空间信息，这是任何大规模火灾管理方法的核心。研究结果为研究进展、防火优先级、灭火措施、经济激励分配以及城市和城郊规划等方面提供支持。
