The increasingly globalized trade in plant material has caused the emergence of new invasive pests in many ecosystems. An example is the aggressive alder pathogen Phytophthora ×alni in European riparian forests. Due to the ecological importance of alder to the functioning of rivers and the increasing incidence of P. ×alni-induced alder decline, eff...

The forest-based sector plays a significant role in supporting Europe on its pathway towards a more integrated and bio-based circular economy. Beyond the supply of timber, forest ecosystems offer a wide range of products and services beneficial to human wellbeing. Non-wood forest products (NWFPs) play an integral role in provisioning forest ecosyst...

Sustainable forest management planning is challenged by the expectation for natural resources to provide a broad range of ecosystem services (ES). This can become more complex in joint management areas because the decision can involve several to many actors with different interests and objectives. The goal of this research is to facilitate forest...

The provision of ecosystem services depends on the landscape-level distribution of forest management options over extended planning horizons. Nevertheless, transportation costs are an important fraction of total procurement costs. Therefore, forest managers are challenged by the need to make decisions regarding the design of the road network needed...

Forest management planning can be challenging when allocating multiple ecosystem services (ESs) to management units (MUs), given the potentially conflicting management priorities of actors. We developed a methodology to spatially allocate ESs to MUs, according to the objectives of four interest groups—civil society, forest owners, market agents, an...

Forests are of major importance to people, providing fundamental ecosystem services (ESs). Increasing the supply of an ES might negatively affect the supply of another ES. For example, increasing game densities might reduce timber production. Such trade-offs among ESs may lead to conflicts between actors interested in prioritizing different ESs. Th...

Forest management planning is a challenge due to the diverse criteria that need to be considered in the underlying decision-making process. This challenge becomes more complex in joint collaborative management areas (ZIF) because the decision now may involve numerous actors with diverse interests, preferences, and goals. In this research, we presen...

Within forest governance research, the transfer of power from governmental actors to civil society and market actors has been subject to intense scientific debate. We move forward on this debate by analyzing how ongoing transformations and power shifts in forest governance affect the power relations of actors with interest in various ecosystem serv...

Forest management planning is often challenged by the need to address contrasting preferences from several actors. Participatory approaches may help integrate actors’ preferences and demands and thus address this challenge. Workshops that encompass a participatory approach may further influence actors’ opinions and knowledge through social interact...

Forest management is currently challenged by the need to address an increasing demand for a wide range of ecosystem services. Addressing this challenge requires landscape-level supply approaches that may bring together multiple interests and goals of forest actors. Characterizing these interests and the corresponding forest management context is th...

In this paper, we present a web-based decision support system (DSS)—wSADfLOR—to facilitate the access of stakeholders to tools that may contribute to enhancing forest management planning. The emphasis is on a web-based architecture and a web graphic user interface (wGUI) that may effectively support the analysis of trade-offs between ecosystem serv...

After the catastrophic wildfires in 2017, it was critical to explore the needs for alternative forest management (aFMMs) over 14,840 ha in the Vale do Sousa case study area (CSA), located at the North‐Western Portugal, namely as a landscape management planning between Entre-Douro-e-Sousa (north of the Douro river) and Paiva (south of the Douro rive...

Poster presented at the International conference on Wild Forest Products in Europe (Star Tree Final conference)

The interest in sustainable development and environmental management from non-wood forest products (NWFPs) has been growing during the past decade. These products are important in the bio-economy especially in regions where wood is not the most profitable product. As NWFPs cover a wide range of species they provide an array of alternatives to use m...

In this paper, we present a forest management planning web-based decision support system (SADfLOR). The system enables remote visualization of ecosystem services potential supply values as well as of trade-off information. This is influential to evaluate the levels of achievement of various objectives in order to help users build strategic and sust...

The deliverable identify the improvements developed or needed to be developped in order to overcome the possible weaknesses of different MPT and NWFP models. The main body of the deliverable is structured in two chapters. The first part (chapter 2) is focused on those existing models that already present a high degree of development and that were a...

ABSTRACT: In this dissertation geostatistical methods are applied to define the limit of a study area (1 million hectares), in the south of Portugal, at Alentejo, and to predict the cork oak growth index (cgi) and the degree of canopy damage (dcd) for cork oak (Quercus suber L.) and holm oak (Quercus ilex spp rotundifolia Lam) stands. These variab...

This paper presents preliminary results of research about the development of a forest ecosystem management decision support system (FEMDSS) in Portugal. Key components of the FEMDSS are characterized. The data model and its technological application is briefly outlined. The structure of the interactive natural resources simulator is described. Focu...

A utilização de sistemas de informação geográfica (SIG) em gestão de recursos florestais em Portugal privilegiou no passado a possibilidade de produção de mapas. Neste contexto, não se tirou partido do potencial da sua integração em sistemas de apoio à decisão; menosprezou-se a sua ligação com módulos de projecção do crescimento das espécies flores...
