Lake Duparquet Fire History Reconstruction From Tree Rings

Fire history data spanning 479 years, from 445 to -34 calendar years before present, reconstructed from tree-ring analysis on Lake Duparquet Island. The dataset was archived by NOAA National Centers for Environmental Information under its Paleoclimatology program. The original study was published in 1984.

Use Cases

• Analyze fire frequency and return intervals over the 479-year period using the calendar years before present timeline.
• Model relationships between climate proxies and fire occurrence events recorded in the tree-ring parameters.
• Reconstruct historical fire regimes for the Quebec, Canada region to establish ecological baselines.

Strengths

• 479-year temporal coverage provides a multi-century context for fire history.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's temporal coverage ends 34 years before present (1964 CE), limiting analysis of modern fire dynamics.
• Data is from a single geographic location (Lake Duparquet Island), which may not represent broader regional patterns.
