Lake Duparquet Fire History Reconstruction From Tree Rings

NOAA/WDS Paleoclimatology archives fire history data from Lake Duparquet Island in Quebec, Canada. The dataset reconstructs fire events using tree-ring parameters, covering a period from 37 to -34 calendar years before present. The National Centers for Environmental Information (NCEI) maintains this study, which was last updated in 1984.

Use Cases

• Analyze fire frequency and return intervals using the calendar years before present (BP) time series.
• Correlate fire history parameters with other paleoclimate proxies for the Quebec region.
• Model past fire regimes by examining the tree-ring data features for fire scars or growth anomalies.
• Reconstruct regional fire chronology for the Lake Duparquet area using the dated fire events.

Strengths

• Data covers a 71-year period (from 37 to -34 BP) for fire event analysis.
• Archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Temporal coverage is limited to a specific 71-year window, not a long-term millennial-scale record.
• Data is geographically focused on a single island site (Lake Duparquet), limiting broad spatial analysis.
• The dataset's last update was in 1984, potentially lacking modern methodological refinements.
