Elevation and aspect were measured at the center of plot (mid-point on plot), and latitude/longitude were recorded from GPS readings taken at the upper end of each transect. Each transect included two rectangular stand assessment plots, 10 m×50 m. Percent whitebark pine in overstory is based on a count of canopy-level trees within each plot. See text for details.
