Lake Duparquet Fire History from Tree Rings

NOAA's archived paleoclimatology study provides fire history data derived from tree rings for Lake Duparquet Island in Quebec, Canada. The temporal coverage spans from 374 to -34 calendar years before present. This dataset was produced by NOAA National Centers for Environmental Information and was last updated in 1984.

Use Cases

• Reconstruct historical fire frequency and severity using tree-ring fire scar data.
• Analyze long-term climate-fire relationships by correlating fire event years with other paleoclimate proxies.
• Calibrate and validate regional fire history models for the Quebec boreal forest.
• Study fire return intervals and ecosystem resilience over a multi-century timescale.

Strengths

• Temporal coverage spans 408 calendar years (374 to -34 BP).
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data recency is limited, with a last update recorded in 1984.
• Specific sample size, column details, and file formats are not provided.
