Oregon Fire History Reconstruction from Tree Rings

Fire history data spanning 279 years, from 237 to -42 calendar years before present, reconstructed from tree-ring analysis at the Troy site in Oregon. This paleoclimatology study is archived and provided by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1992.

Use Cases

• Analyze fire frequency and return intervals using the reconstructed fire year chronology.
• Correlate fire event years with regional climate proxy data from the same time-series.
• Model long-term forest disturbance dynamics using the site-specific fire history parameter.

Strengths

• Covers a 279-year period of reconstructed environmental history.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service.

Limitations

• The dataset's temporal coverage ends over 2000 years before present, limiting modern comparisons.
• Data is specific to a single site (Troy, site 14), reducing regional generalizability.
• The last known update was in 1992, indicating potential staleness in metadata or access methods.
