Fire History Reconstruction from Tree Rings in Coahuila, Mexico

NOAA/WDS Paleoclimatology archives fire history data derived from tree rings at the Las Bateas 2 site in the Sierra Madre Oriental, Coahuila, Mexico. The dataset provides a temporal record of fire events spanning from 427 to -5 calendar years before present. It is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Analyze fire frequency and return intervals using the fire history chronology from tree rings.
• Correlate fire event years with regional climate proxy records to study climate-fire relationships.
• Reconstruct historical fire regimes for the Sierra Madre Oriental region using the dated fire scars.
• Calibrate and validate fire simulation models with site-specific, centuries-long fire history data.

Strengths

• Temporal coverage spans over 430 calendar years, providing a long-term perspective.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's temporal coverage ends at -5 BP, limiting analysis of the most recent centuries.
• Data is specific to a single site (Las Bateas 2), which may not represent broader regional patterns.
• The last recorded update was in 1955, indicating the core data is historically static.
