Abstract
The Mediterranean region hosts some of the oldest trees in Europe growing in high-elevation environments and reaching ages well beyond 800 years. We here present eight of these sites from the Atlas Mountains in the west to the Taurus Mountains in the east and discuss their potential for high-resolution climate reconstruction using dendrochronological techniques. Evidence from ancient trees plays a key role in placing the current temperature and precipitation dynamics into a long-term context and thereby providing a foundation of naturally forced climate variability that is needed to validate model-based 21st century projections. This is demonstrated in a case study using maximum latewood density measurements from Pinus heldreichii in northern Greece to reconstruct July-September temperatures back to 730 CE. While permission for sampling increment cores from ancient trees must be granted for scientists, we argue that these sites must be sheltered from any non-scientific use to keep these treasures of nature and life protected.
