Article
With the publication of the European Green Deal, the European Union has committed to reaching carbon neutrality by 2050. The envisaged reductions of direct greenhouse gases emissions are seen as technically feasible, but if a wrong path is pursued, significant unintended impacts across borders, sectors, societies and ecosystems may follow. Without...

Article
Full-text available
Primary forests, defined here as forests where the signs of human impacts, if any, are strongly blurred due to decades without forest management, are scarce in Europe and continue to disappear. Despite these losses, we know little about where these forests occur. Here, we present a comprehensive geodatabase and map of Europe’s known primary forests...
Article
The demand for timber, bioenergy feedstock and other forest products, leading to intensified forest harvesting, is expected to increase in the coming decades in European Union. A reduction in the delivery of forest ecosystem services and, specifically, biodiversity, including the provision of habitats for mature-forest-dwelling raptors, has been at...

The spatially explicit assessment of land use and land-use change patterns can identify critical areas and provide insights to improve land management policies and associated decisions. This study mapped the land uses and land-use changes in Lithuanian municipalities since 1971. Additionally, an analysis was conducted of three shorter periods, corr...
Article
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...
Article
Full-text available
Effective management decisions regarding greenhouse gas (GHG) emissions may be hampered by the lack of scientific tools for modeling future land use change. This study addresses methodological principles for land use development scenario modeling assumed for use in processes of GHG accounting and management. Associated land use policy implications...
Article
Full-text available
Intensified forestry can be seen as a solution to climate change mitigation and securing energy supply, increasing the production of forest bioenergy feedstock as a substitution for fossil fuels. However, it may come with detrimental impacts on forest biodiversity, especially related to older forests. The aim of this study was to assess the sustain...
Article
Full-text available
Lithuanian forestry has long been shaped by the classical normal forest theory, aiming for even long-term flow of timber, and the aspiration to preserve domestic forest resources, leading to very conservative forest management. With radically changing forest management conditions, climate change mitigation efforts suggest increasing timber demands...
Article
Full-text available
The prerequisite for sustainable management of natural resources is the availability of timely, cost-effective, and comprehensive information on the status and development trends of the management object. An essential source of such information has always been the application of remote sensing. Data and algorithms to use remote sensing in forestry...
Article

Primary forests are critical for forest biodiversity and provide key ecosystem services. In Europe, these forests are particularly scarce and it is unclear whether they are sufficiently protected. Here we aim to: (a) understand whether extant primary forests are representative of the range of naturally occurring forest types, (b) identify forest ty...
Article
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...
Conference Paper

In Lithuania, forests are managed by Lithuanian State Forest Enterprise, municipalities, ministries, etc. and private forest owners. About 50% of all forest land is State importance, privately owned forests cover 40% of forest land, and about 10% of forest land belongs to forests reserved for restitution. Forest management of private ownership forc...

The abundance of grey seals (Halichoerus grypus) in Atlantic and Baltic waters has been increasing in recent years. It is important to understand factors affecting this growth and how the growing population can influence the behaviour of individual seals. Individual behaviour during the lactation period is important for later development in many ma...

Volatile organic compounds (VOCs) emitted by trees in response to abiotic stress evoke high levels of secondary organic aerosol (SOA) compounds. Few techniques exist to provide chemically-resolved submicron (PM1) particle mass concentrations and source apportionment of stress-induced emissions from trees and SOA formation. The chemical composition...

Article
Sympatric species are likely to compete with one another unless there is a low degree of overlap in their resource use, in which case these species are able to coexist. Disclosing of biotic interactions between sympatric species is important from both theoretical and practical perspectives, especially when the species are of conservation concern. H...

Full-text available
Sustainable forest management is driving the development of forest decision support systems (DSSs) to include models and methods concerned with climate change, biodiversity and various ecosystem services (ESs). The future development of forest landscapes is very much dependent on how forest owners act and what goes on in the wider world; thus, mode...
Article
Forest planners in former Eastern Block countries tend to provide conservative forecasts of timber supply, based on a rigid area control under the legislated rotation ages, and often assuming uniform forest management behaviour irrespective of the owner type. This study, in contrast, explores timber supply in a multi-disciplinary approach that anal...
