The impact of extreme weather events such as droughts, heat waves, storms and the associated intensification of bark beetle outbreaks in spruce forests in recent years, has led to a vast loss of spruce trees in Thuringia and other regions in Germany. There are various options for the management of disturbed areas, but their pros and cons are not clearly resolved. The ResEt-Fi consortium implemented a supra-regional field trial to test how specific practices for deadwood management affect the ecological conditions and subsequent reforestation dynamics of natural regeneration and planted trees. It aims at generating climate-stable mixed forests by an ecological valuable transition offering socio-economic benefits. For stakeholders and forest practitioners, it is planned to create guidelines and showcase scenarios for facilitating the selection of management procedures that fit optimally to the regional conditions and goals for mid- and long-term development.
