Synthesis of sample site locations from Morrison & Swanson (unpublished); Teensma (1987); Weisberg (1998) fire history studies, and Giglia (unpublished) supplemental data, used for super-old growth study, Giglia et. al. 2003.

Data quality varies depending on source. See metadata for individual researcher
shapefiles for details on data quality.
This shapefile was created by merging the following shapefiles:
giglia_allsites; m&s_unpub_allsites; teensma_allsites; weisberg_allsites.
Attributes merged were: researcher, x and y coordinates and SOG
presence/absence.
Site elevation was derived from a spatial join between site point
locations and a 20m contour layer.
Fire chronology data were aggregated to century-scale and classified by
severity as follows: Severity Class codes included from Class codes included
from code: Definition: M & S/Teensma fire chron. Weisberg fire chron. H
hi-severity fire occurred at least once 3, 4 5,7 M mixed-severity fire " " " " 5
4 L low-severity fire " " " " 1,2 1,2 S site not included in previous fire
chronologies, but refer to sites where SOG exists; assumption is made that SOG
post-dates high-severity fire The fire chronologies referred to above are in ms
excel format: "BRCHRONO" (DF15) and "brmfc" - see Don Henshaw.
Elevation class was derived from a spatial join with "gen_aspect"
shapefile and refers to the slope position in relation to proximal high
ridges.
Slope class was derived from a spatial join with "slope_class" shapefile
and refers to the slope angle classified by degrees.
General aspect was derived from a spatial join with "gen_aspect" shapefile
and refers to the general aspect of a slope, ignoring
microtopography.
