In recent years forests have been severely damaged due to disturbances. A further increase in frequency and intensity is to be expected. Consequently, large areas will require reforestation. This presents an opportunity to build resilient forests. Nevertheless, forest enterprises face major challenges such as limited financial resources for reforestation. An alternative to reforestation via planting is to actively and strategically incorporate natural regeneration of early-successional tree species like birch. Bio-economic models are useful for scrutinizing potential ecological-economic trade-offs of such decisions. However, current models for Germany lack early-successional tree species. Experiences with birch in larger-scale natural regeneration are largely missing in Germany. In contrast, in Finland, birch is one of the main wood species. They have extensive experience and data on birch regeneration and management. This will help to improve the currently available model by creating more realistic regeneration scenarios including successional tree species and by extending the model from the stand to the landscape (forest enterprise) level.
