Note: See Figure 16 for location of the classes. The divisions within the table show how environmental variation has been differentiated at the 2, 4 and 9-class levels. The total area of each class at the 20-class level is shown in the second column and can be summed to derive the area in classes at the 2, 4 and 9-classes levels.
