Tree-ring data from the Lake Duparquet region in Quebec, Canada, reconstructs fire events over a 458-year period. The dataset covers from 422 to -36 calendar years before present, indicating events both before and after the common reference year. NOAA National Centers for Environmental Information archives this paleoclimatology study.
Use Cases
- Analyze fire frequency and return intervals using the calendar years before present (BP) time series.
- Correlate fire event years from the tree-ring chronology with other paleoclimate proxy records.
- Model historical disturbance regimes in boreal forests using the fire history parameter.
- Reconstruct past vegetation resilience by examining the temporal clustering of fire events.
Strengths
- Covers a 458-year temporal range from 422 to -36 BP.
- Provides a specific geographic location for the study site in Quebec, Canada.
Limitations
- Data collection concluded in 1986, making the record temporally stale for contemporary analysis.
- Sample size and spatial resolution of tree-ring sites are unknown, potentially limiting statistical power.
- The calendar year BP scale requires careful handling for cross-dataset comparison with different reference points.
