Deadwood is recognized as one of the most important resources affecting forest biodiversity.Its absence from the forest landscape is, therefore, of concern, such that one official Swedishenvironmental objective is to increase the volume of deadwood. However, increasing the useof renewable energy sources, another environmental goal, is likely to work against thisbiodiversity objective. In this study we utilize a regional economic forest sector model,focusing on northern Sweden, in order to estimate the effect of a large scale introduction ofstump harvest on the future use of forest fuel. In addition, an ecological model, describing therelationship between the availability of dead wood and the abundance of saproxylic beetles, islinked to the economic model.The parameters used in the economic model are derived from a data set spanning 28 yearswhile the ecological model is derived from a survey of ten clear cuts, undertaken seven yearsafter the clear cutting, in order to investigate the abundance of saproxylic beetles in stumps.We simulate the effects of an increased demand for wood fuels in northern Sweden, with orwithout stump harvest. The two scenarios have different effects on all major round woodmarkets in the region, as well as on the abundance of saproxylic beetles. More specifically,the harvest of stumps is associated with a 5% reduction in the mean abundance of saproxylicbeetles living in deadwood on future clear cuts and a 3% increase in the use of renewableenergy recourses in heating plants.
