  1. R2 = Nagelkerke index. Odds ratio, P values, and χ2 statistics are given for the following factors or factor levels a/ soil type: down-hill system (DhS), alloterite <1.2 m (Alt), superficial lateral drainage (SLD), up-hill system (UhS); superficial hydromorphy (SH) is taken to be the reference b/distance to logging damage (logscale) c/distance to conspecific (Clump, logscale). PEnv is the minimum of PSoil (drainage) and disturbance (PDist). Last column (PTorus) reports the frequency of lower residual deviances found when model is applied after random torus translation of environmental factors map with regard to stem map
