Distribution of tree basal area differences between pairs of the three forest management systems in a moist semi-deciduous forest in Ghana (OG: old-growth, SL: selectively logged, CC: clear-cut logged) across the various diameter classes. If a value bears a superscript of a particular forest management systems, it means that value was contributed by that forest management system (i.e., that forest management system had a higher basal area value than the other forest management systems in the pair).
