Because species often overlapped, the sums of the percentages exceed 100. In addition, to 

 omit any marginal plants that exist at transition zones, a modal elevation differs slightly from the 

 arithmetic or weighted mean. Appendix 3-A contains histograms of species occurrence. Plots of 

 the profiles of each transect, showing the modal elevations of the substrate and zonation of plant 

 species are available from the authors.
