Predicted jack pine succession to other types never fully completes even after centuries.
Evidence
Our plots in jack pine-dominated communities show succession to either fir-spruce-birch or black spruce-feather moss types, as predicted by Ohmann and Ream (1971b). However, these successions were never entirely completed (Tables 7, 8 and Figs. 68). A 1727 burn extending from Frost and Cherokee Lakes east to Winchell Lake supports the oldest remnants of jack pine forest we found (see stand 30, Tables 7 and 8, and Fig. 8). Only six living jack pine were actually found in this age class, but numerous dead and down FIG. — Miron L. Heinselman, Fire in the Virgin Forests of the…, 342
