Vegetation, species composition plot data:
Compare pre-settlement compositionestimates with current stand composition.
Relate pre (and post) settlement compositionwith fire regime characteristics among and betweenplots, sites, and transects.
High variability in forest composition between plots
Estimates of b.a. increase from pre-settlement conditionvaried from 0 to 100%. Average increase ~50%.
Giant sequoia fire record in the Circle Meadow areanow extended back prior to ~600BC with some replication.
