Everett Fire History Reconstruction from Tree Rings in Washington

Washington state fire history data derived from tree-ring analysis at the Nile Creek Aspect Polygon 5 site. The NOAA National Centers for Environmental Information archives this paleoclimatology study covering the period from 457 to -46 calendar years before present. The dataset was last updated in 1996.

Use Cases

• Analyze fire_event_year and fire_interval data to reconstruct historical fire frequency and seasonality.
• Correlate fire_history parameters with tree-ring_width or other dendrochronological metrics to assess climate drivers.
• Model fire_return_intervals using the 503-year temporal coverage for ecological forecasting.
• Map fire_scar evidence from core samples to understand spatial patterns within the geographic polygon.

Strengths

• Temporal coverage spans 503 calendar years, from 457 to -46 BP.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1996, making it temporally stale for contemporary analysis.
• Specific sample size, row count, and column details are unknown, limiting reproducibility assessment.
• Geographic coverage is restricted to a single polygon in Washington state, not representative of broader regions.
