    Comparative analysis on the communication strategies of the forest owners associations in Europe

    Full text link
    This research reports a comparative analysis of the communication strategy that forest owners' associations across Europe use to influence society on one side and the decision-makers on the other, in order to fulfill forest owners' interests. 60% of Europe's forests are privately owned by an estimated number of 16 million forest owners, who are represented by forest owners' associations. One of its main functions is to influence the public perceptions on forests and forestry. In this article it is analyzed how a specific forestry stakeholder fixes its strategies to communicate with and lobby society in order to get acceptability for their proposals/demands. Open-end surveys have been used as a source of information in 2006 and repeated in 2012. Besides of the comparison among countries, a comparison along the time has been also performed. The whole communication frame is analyzed, considering the objectives, the structure, the messages, the channels, and the evaluation. The main conclusions that arise are: first, the temporary comparison (2006 2012) results into an improvement in several issues; second, there is room for improvement of professionalization of communication in forest owners' associations in Europe; third, social research into public perception of forestry might help to define communication strategies.Fabra Crespo, M.; Rojas Briales, E.

    Species-specific, pan-European diameter increment models based on data of 2.3 million trees

    ResearchBackground: Over the last decades, many forest simulators have been developed for the forests of individual European countries. The underlying growth models are usually based on national datasets of varying size, obtained from National Forest Inventories or from long-term research plots. Many of these models include country- and location-specific predictors, such as site quality indices that may aggregate climate, soil properties and topography effects. Consequently, it is not sensible to compare such models among countries, and it is often impossible to apply models outside the region or country they were developed for. However, there is a clear need for more generically applicable but still locally accurate and climate sensitive simulators at the European scale, which requires the development of models that are applicable across the European continent. The purpose of this study is to develop tree diameter increment models that are applicable at the European scale, but still locally accurate. We compiled and used a dataset of diameter increment observations of over 2.3 million trees from 10 National Forest Inventories in Europe and a set of 99 potential explanatory variables covering forest structure, weather, climate, soil and nutrient deposition. Results: Diameter increment models are presented for 20 species/species groups. Selection of explanatory variables was done using a combination of forward and backward selection methods. The explained variance ranged from 10% to 53% depending on the species. Variables related to forest structure (basal area of the stand and relative size of the tree) contributed most to the explained variance, but environmental variables were important to account for spatial patterns. The type of environmental variables included differed greatly among species. Conclusions: The presented diameter increment models are the first of their kind that are applicable at the European scale. This is an important step towards the development of a new generation of forest development simulators that can be applied at the European scale, but that are sensitive to variations in growing conditions and applicable to a wider range of management systems than before. This allows European scale but detailed analyses concerning topics like CO2 sequestration, wood mobilisation, long term impact of management, etcinfo:eu-repo/semantics/publishedVersio

    Landscape trajectory of natural boreal forest loss as an impediment to green infrastructure

    Loss of natural forests by forest clearcutting has been identified as a critical conservation challenge worldwide. This study addressed forest fragmentation and loss in the context of the establishment of a functional green infrastructure as a spatiotemporally connected landscape-scale network of habitats enhancing biodiversity, favorable conservation status, and ecosystem services. Through retrospective analysis of satellite images, we assessed a 50- to 60-year spatiotemporal clearcutting impact trajectory on natural and near-natural boreal forests across a sizable and representative region from the Gulf of Bothnia to the Scandinavian Mountain Range in northern Fennoscandia. This period broadly covers the whole forest clearcutting period; thus, our approach and results can be applied to comprehensive impact assessment of industrial forest management. The entire study region covers close to 46,000 km2 of forest-dominated landscape in a late phase of transition from a natural or near-natural to a land-use modified state. We found a substantial loss of intact forest, in particular of large, contiguous areas, a spatial polarization of remaining forest on regional scale where the inland has been more severely affected than the mountain and coastal zones, and a pronounced impact on interior forest core areas. Salient results were a decrease in area of the largest intact forest patch from 225,853 to 68,714 ha in the mountain zone and from 257,715 to 38,668 ha in the foothills zone, a decrease from 75% to 38% intact forest in the inland zones, a decrease in largest patch core area (assessed by considering 100-m patch edge disturbance) from 6114 to 351 ha in the coastal zone, and a geographic imbalance in protected forest with an evident predominance in the mountain zone. These results demonstrate profound disturbance of configuration of the natural forest landscape and disrupted connectivity, which challenges the establishment of functional green infrastructure. Our approach supports the identification of forests for expanded protection and conservation-oriented forest landscape restoration.

    Collection and consumption of non-wood forest products in Europe

    Many Non-Wood Forest Products (NWFPs) such as mushrooms and berries are collected and consumed in Europe; but both national statistical and scientific data on this topic are reported only for a limited number of countries, products, and case-study areas. Without an adequate quantitative basis, their importance as source of food and income, their links to recreation and cultural heritage, are all under-valued in forest-focused and forest-related policies. In this study we aimed to address this gap by assessing the consumption and collection of NWFPs through a statistically-representative survey in 28 European countries with over seventeen thousand respondents. Our results show that ninety percent of households consume NWFPs and about one quarter collects them. The consumption and collection rates, as well as the number of collected products and their contribution to household income, increase from West to East of Europe. The vast majority of collected products is consumed fresh. Households with higher income consume a more diverse range of NWFPs, especially in Western Europe. The relation between income and collection is more ambiguous, but there is some indication that the collection rate is higher than average among higher-income households in North and Western Europe, and among lower income households in Eastern and South-Eastern Europe. Households for which NWFP collection is the main income source are predominantly located in Eastern Europe, and they focus their activities on few key products. Our results also identify recreational, hobby and professional collectors, whose characteristics vary across socio-economic variables and geographical gradient. Recreational collectors in Western and Southern Europe collect 8 kilos of NWFPs from 5 different products, while recreational collectors in Central-Eastern and North-Baltic Europe collect about four times more from ten different products. Hobby collectors collect about one hundred kilos of NWFP per year and professional collectors half a ton, where both groups focus on eight to twelve different products. Professional collectors are predominantly located in Eastern and South-Eastern Europe. We end the study by pointing to future research directions and with a series of policy recommendations on how NWFPs could be addressed along the geographical, income, and urban-rural gradient with respect to their role in forest recreation, as a food and income source
