• Vegetation, species composition plot data
• Compare pre-settlement composition
• estimates with current stand composition.
• Relate pre (and post) settlement composition
• with fire regime characteristics among and
  between
• plots, sites, and transects.

Giant sequoia fire record in the Circle Meadow
area now extended back prior to 600BC with some
replication.
High variability in forest composition between
plots
Estimates of b.a. increase from pre-settlement
condition varied from 0 to 100. Average
increase 50.
