Taxonomic standard used: USDA Plants Database
How plots were selected: Locations (not plots) were selected on the basis of accessible locations with mature red spruce within the natural range in northern NY and New England. “Accessibility” includes permission to collect both increment cores and soil samples over the course of two years.
How trees were selected: Trees were selected on the basis of being canopy-dominant or subdominant, free of obvious stem defects and disease, and being representative of those at the location with respect to crown condition.
Exclusion of trees (if any): The sampling was not intended to be exhaustive, nor to represent a fixed spatial area. Consequently, not all trees were sampled. Again, the trees are at the location, but there are not plots as such.
How cores were collected: Two 12-mm diameter cores from each tree were collected manually at breast height with a Suunto increment borer.
How cores were processed: Cores were air-dried, mounted in grooved wooden blocks, and sanded with a graded series of sandpaper.
Exclusion of cores (if any): Occasionally, cores would contain pin knots or other defects and would not be measured for ring widths.
