From: Tree-Ring Indicators of Fire in Two Old-Growth Coast Redwood Forests
Anatomical indicators of known and suspected fires for redwoods at Landels-Hill Big Creek Reserve. Red boxes show year of event and red arrows point to indicators. Black boxes in lower right corners cover 1 mm2. Growth proceeds from left to right for A to F, and bottom to top for G. A) Traumatic resin ducts (TRD) and infused resin in the earlywood of 2001 at 70 m; B) TRD in 1988 at 40 m; C) TRD and infused resin in the latewood of 1864 and earlywood of 1866 at 10 m; D) TRD in the latewood of 1841 at 40 m; E) TRD in the latewood of 1977 at 3 m; F) TRD in the earlywood of 1634 at 3 m for remnant; and G) scar from 1985 fire showing a) char, b) ring separation, c) mid-ring scar, d) TRD and discolored wood for subsequent growth rings.
