The main objective of this work was to analyse how increased harvesting for bioenergy production might affect other Ecosystem Services (ES) in two Norwegian municipalities (Ringsaker and Voss). The aim was to identify locations where synergies or conflicts between ES could be expected. The spatial distribution of eight different ES (3 provision, 3 regulation and 2 cultural services) was modelled using information provided by land use spatial databases and additional data sources. Model parameters were set by integrating existing research and expert knowledge. Maps showing the level of provision of ES were analysed using a moving window to analyse scale dependence in the spatial distribution of ES provision. Map algebra was then used to identify areas providing multiple ES, thus defining the most important areas on which to focus the management of both synergies and trade-offs. Finally, specific ‘binary bundles’ maps, where bioenergy provision was compared with each of the other ES, were developed. The methodology proved its utility to assess the compatibility of bioenergy uses with other services. This straightforward approach is readily replicable in other regions and can be used as a decision support tool for planning and designing provision areas, and to ensure sustainable forest management approaches.

Abstract
Gjengroing av område som tidlegare vart slått eller nytta som beite er ein av årsakene til at seminaturlege naturtypar er raudlista. Dette er ein stor trugsel for arter som til dømes solblom, dragehode og mogop.

Abstract
In modern agricultural landscapes, «the green in between» plays a crucial role in supporting the survival of many plant and animal species. These areas include field margins, grassy banks between fields, mid-field islands of uncultivated vegetation, rocky outcrops, fallow land, and other patches of unused ground. We surveyed vascular plant species in these green spaces and compared the results with a similar survey conducted 18 years earlier. Our findings reveal a general decline in species richness, including many plants important for pollinators. Nevertheless, numerous green patches remain species-rich and continue to provide valuable resources for pollinators. Among these, road verges stood out as the most diverse. This suggests that active management of the green in between—such as removing invasive species and implementing regular mowing to maintain flower-rich patches—could significantly enhance its value for wildlife and biodiversity conservation.
