# Methods: See Brown, P.M. 2001. Increment cores were removed from
# approximately 10 cm height above ground level on living trees and cross
# sections were cut from stumps, logs, and snags such that one surface was
# at an estimated 10 cm height above root crown. Cores sampled had to be
# no more than a field-estimated 10 years from pith. On increment cores
# or cross sections that did not include pith but inside ring curvature
# was visible, pith dates were estimated using overlaid concentric circles
# of varying diameters that take into account both average inside ring
# widths and an estimated distance to pith.

# Comments: Twenty-two of 26 trees were dated from this very open stand.
# We were only able to sample 27 pre-settlement trees within 50 m radius
# of plot center.  All were either living or stumps except for 2 snags.
# Trees dated to the early 1700s cohort (11 trees between 1721 and 1730)
# or had piths scattered in the latter 1700s to latter 1800s.  Fire scars
# were common on the stumps, and included a unique scar on one tree at 1777.
# A scar also was recorded on one tree at 1819 while other trees recorded
# scars at the more common date of 1822.
