Coring dominant fire-adapted trees dates stand origin after burns.
Evidence
Stand-origin dates were obtained mostly from cores of dominant trees of species known to reproduce well after fires. … Usually two to five trees were cored for ages on each plot. Jack pine and red pine were used whenever available. Other trees used occasionally were white pine, black spruce, white spruce, and aspen. Dominant trees of fire-adapted species were used because the objective was to get an estimate of the time of origin of the stand. — Miron L. Heinselman, Fire in the Virgin Forests of the…, 93
