Assessment of the hierarchical order of interactions among forest layers showed that overstory broadleaf abundance, through its influence on soil nutrients, promotes cover and richness of shrub and herb layer species, but limits bryophytes and lichens. Shrub layer facilitates or is tolerated by herb layer species, but cover and richness of shrub and herb layers adversely affect bryophytes and lichens.
