Floristic analysis of the undisturbed forestTable 4.1. List of trees (T), shrubs (S) and climbers (C) in abundance rank order. Thecolumn head ‘RO’= rank order of the average abundance per plot of the species(N) in a descending; i.e., rank order and 1 is the first and most abundant species.Note also other columns: N = average abundance; %N = relative abundance ofthe species; LN = local abundance; F = absolute frequency; %F = relativefrequency; BA= basal area (m 2 ha -1 ). The list that includes all species withauthors is found in Appendix 1. Full description of the abbreviated distributiontype of some trees given below is found in Appendix 3.RO Species Family N %N.
