Physisch-geographisches Kolloquium (PG):
Reconstruction of Past Hydroclimate Variability in Iran from a Multi-Centennial and Multi-Parameter Juniper Tree-Ring Network
Dr. Zeynab Foroozan (Institut für Geographie, FAU Erlangen-Nürnberg)
Moderation: Prof. Dr. Achim Bräuning
Understanding how ecosystems respond to long-term climate variability is essential, especially in regions increasingly affected by drought and water scarcity. Iran has a long history of climate-related crises, primarily driven by droughts and flash floods, which are being intensified by ongoing climate change. In this talk, I present the JunIRANet project, which uses tree-ring records from Juniperus polycarpus across Iran to reconstruct hydroclimatic variability over the past centuries. By integrating multiple parameters from tree rings—including growth and stable isotopes—we gain insight into historical drought patterns, long-term trends, and the frequency and severity of extreme events. This approach also allows us to explore the ecological consequences of different types of drought. The talk will demonstrate how natural archives such as tree rings offer valuable long-term perspectives on environmental change and are essential for understanding forest responses to complex hydroclimatic extremes in semi-arid regions like Iran.
