Description: In 2003, a severe region-wide event damaged over 90% of red spruce in the northeastern US. We assessed the influence of the 2003 winter injury event on long-term growth and C sequestration of red spruce trees by measuring the xylem growth (basal area increment) in forest stands in Vermont, New Hampshire, and Massachusetts where winter injury was quantified in 2003. To do this, we assessed dominant and co-dominant red spruce trees in 30 forest plots (10–15 trees per plot) from 14 locations that had been quantified for winter injury severity (visual assessment of damage to current-year foliage, ranging from 0% to 100%) in 2003 (a sub-set of the 27 locations and 176 plots assessed by Lazarus et al., 2004).

How plots were selected: We selected 30 red spruce plots that had been quantified for winter injury severity in 2003 (a sub-set of the 27 locations and 176 plots assessed by Lazarus et al., 2004) in VT, NH, and MA.
How trees were selected: We used dominant and co-dominant red spruce that were previously selected and assessed for winter injury damage in 2003 (Lazarus et. al. 2004).
Exclusion of trees (if any): We included all trees that had been previously assessed, including dead trees.
How cores were collected: We collected xylem increment cores in fall 2010. Two cores per tree were collected at stem DBH (1.3 m aboveground level) with a 5 mm increment borer at 180° to each other and perpendicular to the dominant slope.
How cores were processed: Cores were mounted in grooved wooden blocks, sanded, and crossdated using the list method (Yamaguchi, 1991). Annual xylem increments were microscopically measured to 0.001 mm resolution using a Velmex sliding stage unit (Velmex Inc., Bloomfield, NY) with MeasureJ2X software (VoorTech Consulting, Holderness, NH) according to methods of Stokes and Smiley (1968). The computer program COFECHA was used to detect and correct for potential crossdating errors in ring series (Holmes, 1983).
Exclusion of cores (if any): No cores were excluded.
