Forest disturbances – a failure to adapt?
Vortragender: Dr. Tanja Sanders, Forest Ecology and Biodiversity, Thünen Institute of Forest Ecosystems (Homepage)Do. 14.10.2021 (12:00-13:30)
In recent years we experience an increase in large scale forest disturbances driven by abiotic as well as biotic agents. Besides the economic loss, especially the impact on biodiversity and forest persistence causes great concern. While it seems easy to distinguish between the damaging causes and some interlinkages are acknowledged, they might be even larger. This becomes especially apparent when looking at the range of individual tree responses to changing climate conditions. In addition to abiotic and biotic causes, internal predisposition might therefore play a larger role for vulnerability and risk assessments. In this presentation I will show case studies from ICP Forests monitoring data as well as dendroecological samples to highlight the individual adaptation processes over time and their limits. I will use examples of risk and vulnerability mapping to explain the need for detailed knowledge on site conditions and disturbance legacy, which will lead to a sneak preview on a project on species selection for future forests. From single tree assessments to large-scale remote sensing we need to combine knowledge, sources, and methods to understand adaptive processes, their limits, and the role they play in forest disturbances. *** Invited by Anke Jentsch, Disturbance Ecology
