Objectives: This research involved resampling a series of permanent plots established in the 1980's and collecting tree cores from red spruce and balsam fir at many of these sites to identify shifts in tree growth and demography associated with recent environmental changes.

Description: This research involved resampling a series of permanent plots established in the 1980's and collecting tree cores from red spruce and balsam fir at many of these sites to identify shifts in tree growth and demography associated with recent environmental changes. To do this, we studied tree species distributions along elevational gradients on 12 mountains in four states of the northeastern United States (New York, Vermont, New Hampshire, and Maine). See Wason et al. (2017) for more information.

Taxonomic standard used: USDA Plants Database
How plots were selected: Plots were selected to represent mature forests in all survey periods (i.e., avoided early successional species composition and stand structure).
How trees were selected: We collected increment cores (2 radii per tree > 20 cm DBH) from 55 P. rubens (26 plots) and 57 A. balsamea (22 plots) across each species’ elevational range, thus sampling across many sites to minimize site effects on tree growth. All trees were in canopy positions and were in apparently good health.
Exclusion of trees (if any): None.
How cores were collected: Selected trees were within 20 m of the vegetation plots and cores were taken 1.3 m above the ground parallel to the elevation contour.
How cores were processed: Cores we recrossdated by species and elevation band (Low, Mid, and High)
Exclusion of cores (if any): A small number of cores (<10) were excluded that did not crossdate well.
