Overall, plots that did not converge did not converge in Aspen. Those plots have Aspen stands with very low basal area (<0.85) and low to medium densities ( between 30 and 90), and medium ages (tage~50), and short topheight (<8) indicating Aspen stands with thin/short individuals. This seems to be valid for SW as well. small basal areas, topheight and densities lead to slower convergence, and some to non-convergence. A few of these plots may not even be classified as forests.

The main question is whether or not we should just ignore Aspen and/or SW in these plots. And, if so, what is the cut-off value. This is more a forestry-related question than a code-related question. It may be the case that some of these plots are not even forests and should be ignored altogether.
