Introduction
I am working on the development and application of decision support systems for multipurpose forest management. The development and application of criteria and indicators for evaluating sustainable forest management at regional, national and international contexts is my interest. In conservation management I am adopting population viability risk management approaches to evaluate conservation management strategies to identify courses of action to improve the viability of populations.

[𝘌𝘹𝘤𝘦𝘳𝘱𝘵 𝘧𝘳𝘰𝘮: 𝗘𝘅𝗲𝗰𝘂𝘁𝗶𝘃𝗲 𝗦𝘂𝗺𝗺𝗮𝗿𝘆] Wildfires, as a global phenomenon, are an integral part of the Earth system which affects different regions of the planet quite unevenly. They are of great concern in Europe: in the European Union alone, over 4000 km2 of our land were burnt in 2019; 3400 km2 in 2020; 5000 km2 in 2021. Depending on the proximity to...

Key message The growth of Shorea robusta is positively correlated with temperature, whereas the relation to moisture is weak. Abstract Tree-ring analyses provide a rich archive of information on environmental attributes affecting tree growth. Tree-ring studies conducted so far have mostly focused on temperate species, and research on tropical tree...
Article
Full-text available
Understanding fires in temperate European coniferous forests is hindered by a lack of reliable field observations on fuel load and structure. Fuel load influences the spread, intensity and spotting distance of a surface fire, torching likelihood and potential carbon emissions. We quantified fuel load and structure for Austrian coniferous forests us...

The interlinked character of the 2030 Agenda poses both a challenge and an opportunity in terms of coherent policy making. Accordingly, different methods have been used in approaching the interactions between SDG entities (goals, targets, indicators, policies, external entities) in several recent publications. In this paper, we provide a review and...

Article
The European spruce bark beetle ‘Ips typographus L.’ is the most serious disturbance agent for European forests. The complex interactions of many influencing factors need to be integrated into a model-based decision-support system to reduce the potential loss of forests. This paper compares two methodological approaches for spatially-explicit predi...

Changes in climate, land use, and land management impact the occurrence and severity of wildland fires in many parts of the world. This is particularly evident in Europe, where ongoing changes in land use have strongly modified fire patterns over the last decades. Although satellite data by the European Forest Fire Information System provide large-...
Article
• Key message Due to social and environmental changes over the last decade, managers use multi-attribute decision-making techniques and geographic information systems to support participatory planning. Several studies have indicated that the combined use improves forest planning by applying a set of key criteria to simultaneously evaluate various e...
Article
Full-text available
The understanding of spatial distribution patterns of native riparian tree species in Europe lacks accurate species distribution models (SDMs), since riparian forest habitats have a limited spatial extent and are strongly related to the associated watercourses, which needs to be represented in the environmental predictors. However, SDMs are urgentl...

Non-wood forest products (NWFP) are important goods provided by forest ecosystems. They comprise a group of products derived from mushrooms and truffles, understory plants to tree products, but also including animals and their products sourced from forests. The ecological requirements for the management of NWFP are as broad as the variety found bet...
Chapter
The recent international policy developments fostering a European bio-economy is gradually increasing the forest owners awareness of the potential of non-wood goods. This potential is related to the multiplicity of resources available and a huge portfolio of potential industrial products that can be derived out of them .In addressing these question...

The accurate prediction of the volume of standing trees is a prerequisite for planning and decision making in sustainable forest management. In Nepal, limited information on form factor (i.e. the ratio of the volume of a tree to the product of its basal area and height) is available for economically important tree species. Thus, current management...

Wildfires are becoming an increasing threat to human health, infrastructure, forestry, agriculture and biodiversity. In Alpine regions, fires are often at the start of cascading risks including avalanches, mudslides or rock fall due to the loss of forest and vegetation layers. Additionally, wildfires are expected to occur more frequently in the fut...

Coupled human and natural systems exhibit complex interactions (e.g. feedback-loops) that are often poorly understood. Decision-makers from regional (e.g., state or provincial) scale environmental stewardship programs to international policy makers are often faced with uncertainties about future climatic and sociopolitical conditions (henceforth, s...
Article
In recent decades, changes in fire activity have been observed in Europe. Fires can have large consequences for the provisioning of ecosystem services and for human well-being. Therefore, understanding the drivers of fire occurrence and improving the predictive capability of fire occurrence models is of utmost importance. So far, most studies have...

Non-wood forest Non-wood forest products (NWFPs) have often-underestimated economic potential, particularly for family forest owners. Their role and value, however, is changing in the global West and so are the business opportunities and innovation need associated with them. Focusing on industrialized countries, this chapter gives an overview of th...
