Appendix A
1. River ecological profiles of each transect
The different height and cover percentages (as seen in Tables 3.1, 3.2 and 3.3) of the vegetation classes are presented in these river ecological profiles.
In these river ecological profiles:
The height classes are illustrated on the Y-axis
The five different bands of the cross-section in Figure 3.6 are represented on the X-axis
The cover percentages of the different vegetation types are illustrated on the river ecological profile graphs by means of the keys in Figure A1. For instance, three shrubs on the graphs indicate that it had a cover percentage between 25 and 11%.
Figure A1 Keys to the different cover percentages
156
The graphs on the left illustrate the summer vegetation structures, and those on the right illustrate the winter vegetation structures of the different transects. Therefore, the graphs on the left list the avian abundances (N), species richness (S), and relatively avian densities (RAD – N/1.8ha) of the summer months, as well as the summer CAH in which the transect was clustered in. The graphs on the right list the values of these three parameters during the winter months.
