Tree-ring and fire scar data characterizes fire history across multiple spatial scales in the central Oregon Coast Range. The study compares recent fire patterns from the last 500 years with longer paleo records from lake sediment charcoal. Data was collected by SCIOPS, with a last platform update recorded in 2050.
Use Cases
- Model fire return intervals using fire scar dates and tree age class data across different climate zones.
- Analyze spatial patterns of fire occurrence by correlating fire dates with specific site attributes like aspect and hillslope position (U, M, L).
- Compare recent fire history from tree evidence with long-term charcoal sediment records to identify shifts in fire regimes.
- Reconstruct stand age structure and succession patterns using tree-ring counts from stumps at sampled clearcut sites.
Strengths
- Data collection designed to represent the study area proportionally across different aspects and climate zones.
- Sampling includes three distinct hillslope positions (upper, middle, lower) at each site for topographic analysis.
Limitations
- Specific quantitative metrics like total row count, column names, and dataset size are unknown.
- The temporal coverage of the primary tree-ring data is limited to approximately the last 500 years, with older context dependent on paleo records.
